Lutzomyia antunesi has been commonly reported in outbreaks of
cutaneous leishmaniasis (CL) in the Orinoquia region of Colombia. The bionomics
of this species were studied in the municipality of Villavicencio (Meta,
Colombia). Sandflies were captured over the course of one week per month for one
year in intradomiciliary, peridomiciliary and extradomiciliary housing areas.
The captures were performed from 06:00 pm-06:00 am using CDC light traps and the
females were processed for polymerase chain reaction (PCR) to detect
Leishmania spp. A total of 22,097 specimens and 19 species
were captured of which Lu. antunesi (89%) and Lutzomyia
walkeri (5%) were the most abundant. Other species recognised as
anthropophilic (Lutzomyia panamensis, Lutzomyia
gomezi, Lutzomyia flaviscutellata and
Lutzomyia fairtigi) were present in very low abundance
(< 2%). Natural infection with Leishmania spp was detected using PCR in
Lu. antunesi, Lu. panamensis and
Lu. flavicutellata, showing infection rates of 1%, 4.8% and
7.5%, respectively. The present paper provides information on various ecological
aspects of Lu. antunesi. An analysis of seasonality shows that
this species increases in abundance in the hottest months (December, January and
February), directly correlating with the maximum temperature and inversely
correlating with precipitation. The natural infection rate is associated with
the peaks of highest abundance. 相似文献

Studies on natural infection by Leishmania spp of sandflies
collected in endemic and nonendemic areas can provide important information on the
distribution and intensity of the transmission of these parasites. This study sought
to investigate the natural infection by Leishmaniain wild female
sandflies. The specimens were caught in the city of Corumbá, state of Mato Grosso do
Sul (Brazil) between October 2012-March 2014, and dissected to investigate
flagellates and/or submitted to molecular analysis to detect
Leishmania DNA. A total of 1,164 females (77.56% of which were
Lutzomyia cruzi) representing 11 species were investigated using
molecular analysis; 126 specimens of Lu. cruziwere dissected and
also submitted to molecular analysis. The infection rate based on the presence of
Leishmania DNA considering all the sandfly species analysed was
0.69%; only Leishmania (Leishmania) amazonensis was identified in
Lu. cruzi by the molecular analysis. The dissections were
negative for flagellates. This is the first record of the presence of L. (L.)
amazonensis DNA in Lu. cruzi, and the first record of
this parasite in this area. These findings point to the need for further
investigation into the possible role of this sandfly as vector of this parasite. 相似文献

The composition and seasonal occurrence of sandflies were investigated in coffee
agroecosystems in the Soconusco region of Chiapas, Mexico. Insect sampling was
performed on three plantations located at different altitudes: Finca Guadalupe Zajú
[1,000 m above sea level (a.s.l.)], Finca Argovia (613 m a.s.l.) and Teotihuacán del
Valle (429 m a.s.l.). Sandflies were sampled monthly from August 2007-July 2008 using
three sampling methods: Shannon traps, CDC miniature light traps and Disney traps.
Sampling was conducted for 3 h during three consecutive nights, beginning at sunset.
A total of 4,387 sandflies were collected during the course of the study: 2,718
individuals in Finca Guadalupe Zajú, 605 in Finca Argovia and 1,064 in Teotihuacán
del Valle. The Shannon traps captured 94.3% of the total sandflies, while the CDC
light traps and Disney traps captured 4.9% and 0.8%, respectively. More females than
males were collected at all sites. While the number of sandflies captured was
positively correlated with temperature and relative humidity, a negative correlation
was observed between sandfly numbers and rainfall. Five species of sandflies were
captured: Lutzomyia cruciata , Lutzomyia texana ,
Lutzomyia ovallesi , Lutzomyia cratifer /
undulata and Brumptomyia sp. Lu.
cruciata , constituting 98.8% of the total, was the most abundant
species. None of the captured sandflies was infected with Leishmania
spp. 相似文献

Visceral leishmaniasis (VL) in Brazil is transmitted by the phlebotomine
Lutzomyia longipalpis and in some midwestern regions by
Lutzomyia cruzi. Studies of the phlebotomine fauna, feeding
habits and natural infection rate by Leishmania contribute to
increased understanding of the epidemiological chain of leishmaniases and their
vectorial capacity. Collections were performed in Jaciara, state of Mato Grosso from
2010-2013, during which time 2,011 phlebotomines (23 species) were captured (68.70%
Lu. cruzi and 20.52% Lutzomyia whitmani).
Lu. cruzi females were identified by observing the shapes of the
cibarium (a portion of the mouthpart) and spermatheca, from which samples were
obtained for polymerase chain reaction to determine the rates of natural infection.
Engorged phlebotomines were assessed to identify the blood-meal host by ELISA. A
moderate correlation was discovered between the number of Lu. cruzi
and the temperature and the minimum rate of infection was 6.10%. Twenty-two females
were reactive to the antisera of bird (28%), dog (3.30%) and skunk (1.60%). We
conclude that Lu. cruzi and Lu. whitmani have
adapted to the urban environment in this region and that Lu. cruzi
is the most likely vector of VL in Jaciara. Moreover, maintenance of
Leishmania in the environment is likely aided by the presence of
birds and domestic and synanthropic animals. 相似文献

We evaluated the effects of Leishmania spp infection on several
population parameters of Lutzomyia longipalpis sensu lato
andLutzomyia pseudolongipalpis, vectors of visceral leishmaniasis
in Venezuela, under experimental conditions during the first post-feeding period.
Females of both species were allowed to feed and engorge on a suspension of fresh
washed human red blood cells in foetal calf serum. These blood cells were either
non-infected or infected with one of the fourLeishmania spp strains
and were offered through a chicken skin membrane. The longevity, life expectancy and
the fecundity of uninfected flies were similar in both species, but the fertility was
significantly lower in uninfected Lu. longipalpis females. In all
cases, the infection of Lu. longipalpis and Lu.
pseudolongipalpis by the Leishmania strains resulted in
significant detrimental effects, which exerted a fitness cost expressed by reduced
survival and life expectancy, as well as decreased fertility and fecundity compared
with the control groups. Nevertheless, differences in these parameters were observed
between these vector species depending on whether they were infected with the
autochthonous Venezuelan Leishmania infantum strain (NESA) or the
Brazilian reference strain (PP75). The experimental data obtained agree with field
data on the natural infection of these vector species and the significance of this
scenario is discussed. 相似文献

In Panama, species of the genus Lutzomyia are vectors of American cutaneous leishmaniasis (ACL). There is no recent ecological information that may be used to develop tools for the control of this disease. Thus, the goal of this study was to determine the composition, distribution and diversity of Lutzomyia species that serve as vectors of ACL. Sandfly sampling was conducted in forests, fragmented forests and rural environments, in locations with records of ACL. Lutzomyia gomezi, Lutzomyia panamensis and Lutzomyia trapidoi were the most widely distributed and prevalent species. Analysis of each sampling point showed that the species abundance and diversity were greatest at points located in the fragmented forest landscape. However, when the samples were grouped according to the landscape characteristics of the locations, there was a greater diversity of species in the rural environment locations. The Kruskal Wallis analysis of species abundance found that Lu. gomezi and Lu. trapidoi were associated with fragmented environments, while Lu. panamensis, Lutzomyia olmeca bicolor and Lutzomyia ylephiletor were associated with forested environments. Therefore, we suggest that human activity influences the distribution, composition and diversity of the vector species responsible for leishmaniasis in Panama. 相似文献

Factors shaping the distribution and abundance of species include life‐history traits, population structure, and stochastic colonization–extinction dynamics. Field studies of model species groups help reveal the roles of these factors. Species of Caenorhabditis nematodes are highly divergent at the sequence level but exhibit highly conserved morphology, and many of these species live in sympatry on microbe‐rich patches of rotten material. Here, we use field experiments and large‐scale opportunistic collections to investigate species composition, abundance, and colonization efficiency of Caenorhabditis species in two of the world''s best‐studied lowland tropical field sites: Barro Colorado Island in Panamá and La Selva in Sarapiquí, Costa Rica. We observed seven species of Caenorhabditis, four of them known only from these collections. We formally describe two species and place them within the Caenorhabditis phylogeny. While these localities contain species from many parts of the phylogeny, both localities were dominated by globally distributed androdiecious species. We found that Caenorhabditis individuals were able to colonize baits accessible only through phoresy and preferentially colonized baits that were in direct contact with the ground. We estimate the number of colonization events per patch to be low. 相似文献

This study updates the geographic distributions of phlebotomine species in
Central-West Brazil and analyses the climatic factors associated with their
occurrence. The data were obtained from the entomology services of the state
departments of health in Central-West Brazil, scientific collections and a literature
review of articles from 1962-2014. Ecological niche models were produced for sandfly
species with more than 20 occurrences using the Maxent algorithm and eight climate
variables. In all, 2,803 phlebotomine records for 127 species were analysed.
Nyssomyia whitmani, Evandromyia lenti and Lutzomyia
longipalpis were the species with the greatest number of records and were
present in all the biomes in Central-West Brazil. The models, which were produced for
34 species, indicated that the Cerrado areas in the central and
western regions of Central-West Brazil were climatically more suitable to sandflies.
The variables with the greatest influence on the models were the temperature in the
coldest months and the temperature seasonality. The results show that phlebotomine
species in Central-West Brazil have different geographical distribution patterns and
that climate conditions in essentially the entire region favour the occurrence of at
least one Leishmania vector species, highlighting the need to
maintain or intensify vector control and surveillance strategies. 相似文献

Cutaneous leishmaniasis (CL) in the state of Rio de Janeiro is sporadic and can
be characterised as a peridomestic transmission that occurs in modified natural
environments. The aim of this work was to study the fauna and ecological
characteristics of sandflies in an environmentally protected area (the State
Park of Serra da Tiririca) within the remnants of the Atlantic Forest in the
municipalities of Niterói and Maricá and their possible relationship with
leishmaniasis. Captures were performed using light traps during the night once a
month for one year in both sylvatic environments and areas surrounding homes
near the park. A total of 1,037 sandflies were captured, belonging to nine
genera and 12 species: Evandromyia tupynambai (34.1%),
Migonemyia migonei (20.6%), Brumptomyia
cunhai (13.8%), Micropygomyia schreiberi (9.7%),
Psathyromyia lanei (6.5%), Brumptomyia
nitzulescui (5.7%), Evandromyia edwardsi
(5.4%), Nyssomyia intermedia (2.8%), Evandromyia
cortelezzii (0.6%), Pintomyia bianchigalatiae
(0.5%), Lutzomyia longipalpis (0.2%) and Sciopemyia
microps (0.1%). Both Mg. migonei and Ny.
intermedia may be acting as vectors of CL in this area. 相似文献

Coral reefs of the Central Red Sea display a high degree of endemism, and are increasingly threatened by anthropogenic effects due to intense local coastal development measures. Overfishing and eutrophication are among the most significant local pressures on these reefs, but there is no information available about their potential effects on the associated microbial community. Therefore, we compared holobiont physiology and 16S-based bacterial communities of tissue and mucus of the hard coral Acropora hemprichii after 1 and 16 weeks of in-situ inorganic nutrient enrichment (via fertilizer diffusion) and/or herbivore exclusion (via caging) in an offshore reef of the Central Red Sea. Simulated eutrophication and/or overfishing treatments did not affect coral physiology with respect to coral respiration rates, chlorophyll a content, zooxanthellae abundance, or δ 15N isotopic signatures. The bacterial community of A. hemprichii was rich and uneven, and diversity increased over time in all treatments. While distinct bacterial species were identified as a consequence of eutrophication, overfishing, or both, two bacterial species that could be classified to the genus Endozoicomonas were consistently abundant and constituted two thirds of bacteria in the coral. Several nitrogen-fixing and denitrifying bacteria were found in the coral specimens that were exposed to experimentally increased nutrients. However, no particular bacterial species was consistently associated with the coral under a given treatment and the single effects of manipulated eutrophication and overfishing could not predict the combined effect. Our data underlines the importance of conducting field studies in a holobiont framework, taking both, physiological and molecular measures into account. 相似文献

This study aimed to analyse changes in the spatial distribution of Lutzomyia
longipalpis in Posadas, an urban area located in northeastern Argentina. Data
were obtained during the summer of 2007 and 2009 through two entomological surveys of
peridomiciles distributed around the city. The abundance distribution pattern for 2009 was
computed and compared with the previous pattern obtained in 2007, when the first human
visceral leishmaniasis cases were reported in the city. Vector abundance was also examined
in relation to micro and macrohabitat characteristics. In 2007 and 2009, Lu.
longipalpis was distributed among 41.5% and 31% of the households in the study
area, respectively. In both years, the abundance rates at most of the trapping sites were
below 30 Lu. longipalpis per trap per night; however, for areas
exhibiting 30-60 Lu. longipalpis and more than 60 Lu.
longipalpis, the areas increased in both size and number from 2007-2009.
Lu. longipalpis was more abundant in areas with a higher tree and bush
cover (a macrohabitat characteristic) and in peridomiciles with accumulated unused
material (a microhabitat characteristic). These results will help to prioritise and focus
control efforts by defining which peridomiciles display a potentially high abundance of
Lu. longipalpis. 相似文献

Hepatic fibrosis induced by egg deposition is the most serious pathology associated with chronic schistosomiasis, in which the hepatic stellate cell (HSC) plays a central role. While the effect of Schistosoma mansoni eggs on the fibrogenic phenotype of HSCs has been investigated, studies determining the effect of eggs of
S
. japonicum
on HSCs are lacking. Disease caused by
S
. japonicum
is much more severe than that resulting from S. mansoni infection so it is important to compare the pathologies caused by these two parasites, to determine whether this phenotype is due to the species interacting differently with the mammalian host. Accordingly, we investigated the effect of
S
. japonicum
eggs on the human HSC cell line, LX-2, with and without TGF-β (Transforming Growth Factor beta) co-treatment, so as to determine the impact on genes associated with fibrogenesis, inflammation and matrix re-organisation. Activation status of HSCs was assessed by αSMA (Alpha Smooth Muscle Actin) immunofluorescence, accumulation of Oil Red O-stained lipid droplets and the relative expression of selected genes associated with activation. The fibrogenic phenotype of HSCs was inhibited by the presence of eggs both with or without TGF-β treatment, as evidenced by a lack of αSMA staining and reduced gene expression of αSMA and Col1A1 (Collagen 1A1). Unlike S. mansoni-treated cells, however, expression of the quiescent HSC marker PPAR-γ (Peroxisome Proliferator-Activated Receptor gamma) was not increased, nor was there accumulation of lipid droplets. In contrast,
S
. japonicum
eggs induced the mRNA expression of MMP-9 (Matrix Metalloproteinase 9), CCL2 (Chemokine (C-C motif) Ligand 2) and IL-6 (Interleukin 6) in HSCs indicating that rather than inducing complete HSC quiescence, the eggs induced a proinflammatory phenotype. These results suggest HSCs in close proximity to
S
. japonicum
eggs in the liver may play a role in the proinflammatory regulation of hepatic granuloma formation. 相似文献

Lipooligosaccharides are glycolipids found in the cell wall of many mycobacterial species including the opportunistic pathogen Mycobacterium kansasii. The genome of M. kansasii ATCC12478 contains a cluster with genes orthologous to Mycobacterium marinum LOS biosynthesis genes. To initiate a genetic dissection of this cluster and demonstrate its role in LOS biosynthesis in M. kansasii, we chose MKAN27435, a gene encoding a putative glycosyltransferase. Using Specialized Transduction, a phage-based gene knockout tool previously used to generate null mutants in other mycobacteria, we generated a MKAN27435 null mutant. The mutant strain was found to be defective in the biosynthesis of higher LOS subspecies, viz LOS-IV, LOS-V, LOS-VI and LOS-VII. Additionally, a range of low abundance species were detected in the mutant strain and mass spectroscopic analysis indicated that these were shunt products generated from LOS-III by the addition of up to six molecules of a pentose. 相似文献

The aim of the present study was to detect natural infection by Leishmania
(Leishmania) infantum in Lutzomyia longipalpis captured
in Barcarena, state of Pará, Brazil, through the use of three primer sets. With this
approach, it is unnecessary to previously dissect the sandfly specimens. DNA of
280 Lu. longipalpis female specimens were extracted from the
whole insects. PCR primers for kinetoplast minicircle DNA (kDNA), the mini-exon gene
and the small subunit ribosomal RNA (SSU-rRNA) gene of Leishmania
were used, generating fragments of 400 bp, 780 bp and 603 bp, respectively.
Infection by the parasite was found with the kDNA primer in 8.6% of the cases, with
the mini-exon gene primer in 7.1% of the cases and with the SSU-rRNA gene primer in
5.3% of the cases. These data show the importance of polymerase chain reaction as a
tool for investigating the molecular epidemiology of visceral leishmaniasis by
estimating the risk of disease transmission in endemic areas, with the kDNA primer
representing the most reliable marker for the parasite. 相似文献

Clostridium difficile is an emerging enteropathogen responsible for
pseudomembranous colitis in humans and diarrhoea in several domestic and wild animal
species. Despite its known importance, there are few studies aboutC.
difficile polymerase chain reaction (PCR) ribotypes in Brazil and the
actual knowledge is restricted to studies on human isolates. The aim of the study was
therefore to compare C. difficileribotypes isolated from humans and
animals in Brazil. Seventy-six C. difficile strains isolated from
humans (n = 25), dogs (n = 23), piglets (n = 12), foals (n = 7), calves (n = 7), one
cat, and one manned wolf were distributed into 24 different PCR ribotypes. Among
toxigenic strains, PCR ribotypes 014/020 and 106 were the most common, accounting for
14 (18.4%) and eight (10.5%) samples, respectively. Fourteen different PCR ribotypes
were detected among human isolates, nine of them have also been identified in at
least one animal species. PCR ribotype 027 was not detected, whereas 078 were found
only in foals. This data suggests a high diversity of PCR ribotypes in humans and
animals in Brazil and support the discussion of C. difficile as a
zoonotic pathogen. 相似文献

Background
Methylotrophy describes the ability of organisms to grow on reduced organic compounds without carbon-carbon bonds. The genomes of two pink-pigmented facultative methylotrophic bacteria of the Alpha-proteobacterial genus Methylobacterium, the reference species Methylobacterium extorquens strain AM1 and the dichloromethane-degrading strain DM4, were compared.Methodology/Principal Findings
The 6.88 Mb genome of strain AM1 comprises a 5.51 Mb chromosome, a 1.26 Mb megaplasmid and three plasmids, while the 6.12 Mb genome of strain DM4 features a 5.94 Mb chromosome and two plasmids. The chromosomes are highly syntenic and share a large majority of genes, while plasmids are mostly strain-specific, with the exception of a 130 kb region of the strain AM1 megaplasmid which is syntenic to a chromosomal region of strain DM4. Both genomes contain large sets of insertion elements, many of them strain-specific, suggesting an important potential for genomic plasticity. Most of the genomic determinants associated with methylotrophy are nearly identical, with two exceptions that illustrate the metabolic and genomic versatility of Methylobacterium. A 126 kb dichloromethane utilization (dcm) gene cluster is essential for the ability of strain DM4 to use DCM as the sole carbon and energy source for growth and is unique to strain DM4. The methylamine utilization (mau) gene cluster is only found in strain AM1, indicating that strain DM4 employs an alternative system for growth with methylamine. The dcm and mau clusters represent two of the chromosomal genomic islands (AM1: 28; DM4: 17) that were defined. The mau cluster is flanked by mobile elements, but the dcm cluster disrupts a gene annotated as chelatase and for which we propose the name “island integration determinant” (iid).Conclusion/Significance
These two genome sequences provide a platform for intra- and interspecies genomic comparisons in the genus Methylobacterium, and for investigations of the adaptive mechanisms which allow bacterial lineages to acquire methylotrophic lifestyles. 相似文献19.
Responses of bacterial and archaeal communities to the addition of straw during anaerobic digestion of manure at different temperatures (37°C, 44°C and 52°C) were investigated using five laboratory-scale semi-continuous stirred tank reactors. The results revealed that including straw as co-substrate decreased the species richness for bacteria, whereas increasing the operating temperature decreased the species richness for both archaea and bacteria, and also the evenness of the bacteria. Taxonomic classifications of the archaeal community showed that Methanobrevibacter dominated in the manure samples, while Methanosarcina dominated in all digesters regardless of substrate. Increase of the operating temperature to 52°C led to increased relative abundance of Methanoculleus and Methanobacterium. Among the bacteria, the phyla Firmicutes and Bacteroidetes dominated within all samples. Compared with manure itself, digestion of manure resulted in a higher abundance of an uncultured class WWE1 and lower abundance of Bacilli. Adding straw to the digesters increased the level of Bacteroidia, while increasing the operating temperature decreased the level of this class and instead increased the relative abundance of an uncultured genus affiliated to order MBA08 (Clostridia). A considerable fraction of bacterial sequences could not be allocated to genus level, indicating that novel phylotypes are resident in these communities. 相似文献

In several countries, surveillance of insect vectors is accomplished with automatic
traps. This study addressed the performance of Mosquito Magnet® Independence (MMI) in
comparison with those of CDC with CO2 and lactic acid (CDC-A) and CDC light trap
(CDC-LT). The collection sites were in a rural region located in a fragment of
secondary tropical Atlantic rainforest, southeastern Brazil. Limatus
durhami and Limatus flavisetosus were the dominant
species in the MMI, whereas Ochlerotatus scapularis was most
abundant in CDC-A. Culex ribeirensis and Culex
sacchettae were dominant species in the CDC-LT. Comparisons among traps
were based on diversity indices. Results from the diversity analyses showed that the
MMI captured a higher abundance of mosquitoes and that the species richness estimated
with it was higher than with CDC-LT. Contrasting, difference between MMI and CDC-A
was not statistically significant. Consequently, the latter trap seems to be both an
alternative for the MMI and complementary to it for ecological studies and
entomological surveillance. 相似文献
