Bat ectoparasites (Nycteribiidae,Streblidae, Siphonaptera,Heteroptera, Mesostigmata,Argasidae, and Ixodidae) from Algeria

Twenty two species of ectoparasites (Family Nycteribiidae: Nycteribia (Listropoda) schmidlii schmidlii, Nycteribia (Nycteribia) latreillii, Nycteribia (Nycteribia) pedicularia, Penicillidia (Penicillidia) dufourii, and Phthiridium biarticulatum; Family Streblidae: Brachytarsina (Brachytarsina) flavipennis and Raymondia huberi; Order Siphonaptera: Rhinolophopsylla unipectinata arabs, Nycteridopsylla longiceps, Araeopsylla gestroi, Ischnopsyllus intermedius, and Ischnopsyllus octactenus; Order Heteroptera: Cimex pipistrelli, Cimex lectularius, and Cacodmus vicinus; Class Arachnida: Order Mesostigmata: Spinturnix myoti and Eyndhovenia euryalis; Order Ixodida: Family Argasidae: Argas transgariepinus and Argas vespertilionis; Family Ixodidae: Hyalomma dromedarii, Ixodes ricinus, and Ixodes vespertilionis) were recovered from 19 bat species in Algeria. New host records for bats are recorded for the first time: N. schmidlii from Rh. clivosus and R. cystops; N. latreillii from Rh. blasii and P. gaisleri; R. huberi from Rh. clivosus; C. pipistrelli from E. isabellinus and H. savii; C. vicinus from E. isabellinus; S. myoti from P. gaisleri; E. euryalis from P. gaisleri and Rh. blasii; A. vespertilionis from P. gaisleri; I. ricinus from T. teniotis and Rh. hipposideros and H. dromedarii from P. kuhlii. Raymondia huberi is recorded for the first time from Algeria.     

Caprine blood groups. 2. The C,G, H,I, J,K, L,N, and Q systems

Nine blood group systems of goats were identified using 12 caprine reagents produced by absorption of alloimmune antisera. The caprine C blood group system, possibly homologous to the ovine C blood group system, was characterized by two reagents and shown to be controlled by three alleles,C ¹²,C ²⁵, andC ⁻. A more complex blood group system of goats, designated G, was identified using three reagents and shown to be controlled by six codominant alleles (G ^10.19.20,G ^10.19,G ^10.20,G ¹⁰,G ¹⁹,G ²⁰) and a recessive allele (G ⁻). A further seven one-factor two-allelic systems were identified by seven reagents. The nine genetic systems provided exclusion probabilities of 0.479, 0.492, 0.548, and 0.572 in Australian Angora, Dairy, Cashmere, and Texan Angora goat breeds, respectively. This work was supported by a grant from the Australian Stud Book, Alison Road, Randwick, New South Wales 2031, Australia.     

COMPARATIVE MORPHOLOGY OF THE CARPEL IN THE ROSACEAE. V. POMOIDEAE: AMELANCHIER,ARONIA, MALACOMELES,MALUS, PERAPHYLLUM,PYRUS, SORBUS

The carpels of 2 groups of pomoid genera, Amelanchier, Malacomeles, Peraphyllum and Aronia, Malus, Pyrus, and Sorbus, were analyzed morphologically. Open sutures are associated with a lesser extent of tegumentary fusion and ovular bundle–wing bundle fusion than are closed sutures. However, in the genera as a whole (and particularly in Aronia and Sorbus), the extent of sutural closure is inversely related with the amount of intercarpellary adhesion and with the fusion of carpels to the floral cup. In the Amelanchier group and in Malus and Pyrus, ovular- and wing-bundle fusion is directly related with intercarpellary adhesion. Malus and Pyrus have closer structural resemblances with one another than they have with Aronia and Sorbus.     

HETEROCHROMATIN BANDING IN BOYKINIA,HEUCHERA, MITELLA,SULLIVANTIA, TIARELLA,AND TOLMIEA (SAXIFRAGACEAE)

Karyotypic differences were sought among species of Boykinia, Heuchera, Mitella, Sullivantia, Tiarella, and Tolmiea utilizing a modification of the Hy-banding technique. Prominent centromeric and some telomeric heterochromatin banding was observed. Boykinia aconitifolia and species of Sullivantia possess an identical banded karyotype, while four species of Heuchera, Mitella diphylla, Tiarella cordifolia, and Tolmiea menziesii (the latter at the tetraploid level) are characterized by a second, slightly different banded karyotype. In Sullivantia, Giemsa C-banding stains the same chromosomal regions revealed by Hy-banding. Larger amounts of heterochromatin are present in chromosomes of species of Heuchera, Mitella, Tiarella, and Tolmiea than in chromosomes of Sullivantia species and Boykinia aconitifolia. These karyological observations confirm generic relationships and demonstrate the systematic applicability of chromosome banding techniques to plants with very small chromosomes.     

The Boxgrove,England, middle Pleistocene herpetofauna: Paleogeographic,evolutionary, stratigraphic,and paleoecological relationships

Triturus vulgaris (smooth newt), Triturus helveticus or T. vulgaris (palmate or smooth newt), Triturus sp. (newt), Pelobates fuscus (common spadefoot), Bufo bufo (common toad), Bufo calamita (natterjack toad), Bufo sp. (toad), Rana arvalis (moor frog), Rana temporaria (common frog), Rana sp. (frog), Anguis fragilis (slow worm), Lacerta cf. L. vivipara (common lizard), Natrix natrix (grass snake), and Natrix sp. (grass, viperine, or dice snake) were identified at the Middle Pleistocene Boxgrove Site, West Sussex, England. This is the first British fossil record of Pelobates fuscus and the earliest fossil record in Britain for the endangered species Bufo calamita. All of these herpetological species are extant and all of them occur in Britain today with the exception of Pelobates fuscus and Rana arvalis that presently live on the European continent.

The Boxgrove, Westbury, and West Runton British pre‐Anglian Middle Pleistocene herpetofaunas show no apparent differences among themselves in patterns of species composition, diversity, or number of exotics. But these three herpetofaunas together have [1] less species diversity and [2] fewer exotic continental species than in the Cudmore Grove British post‐Anglian Middle Pleistocene herpetofauna.

Only the Terrestral Sequence Unit at Boxgrove yielded enough herpetological species for paleoecological interpretation. These taxa indicate a quiet pool surrounded by a somewhat humid vegetated area that gave way to a more xerophytic sandy area, and a paleoclimate at least as warm and perhaps somewhat warmer than occurs in the area today.     

Chromosome localization of the loci for PEPA,PEPB, PEPS, 1DH1, GSR,MPI, PGM1, NP,SOD1, and ME1 in the common shrew (Sorex araneus)

This report extends the genetic map of the common shrew (Sorex araneus) by adding chromosome assignments for ten genes to the seven already mapped (Pack et al. 1995). A somatic cell hybrid panel was used for the mapping. The genes for peptidase A (PEPA) and isocitrate dehydrogenase-1 (IDH1) map to chromosome de; the genes for phosphoglucomutase-1 (PGM1), superoxide dismutase-1 (SOD1), and mannosephosphate isomerase (MPI) are located on chromosome af; the genes for nucleoside phosphorylase (NP) and glutathione reductase (GSR) are on chromosome ik; and the genes for peptidase S (PEPS), malic enzyme-1 (ME1), peptidase B (PEPB) are found on chromosomes jl, go, and mp respectively.

Localization of growth arrest-specific genes on mouse Chromosomes 1, 7, 8, 11, 13, and 16

Growth arrest in NIH3T3 cells is associated with increased expression of a variety of mRNAs, several of which have been isolated as cDNA clones. Six of these growth arrest-specific (Gas) genes were mapped by following the inheritance of DNA restriction fragment length variants (RFLVs) associated with them in panels of recombinant inbred (RI) strains of mice and in the progeny of backcrosses both between laboratory mouse strains and between a laboratory strain and Mus spretus. The six genes are unlinked. Gas-1 maps to Chromosome (Chr) 13, Gas-2 to Chr 7, Gas-3 to Chr 11, Gas-4 to Chr 16, Gas-6 to Chr 8, and Gas-10 to Chr 1.     

Ontogeny of angiopoietin‐like protein 1, 2, 3, 4, 5, and 7 genes during chick embryonic development

Angiopoietin‐like proteins (ANGPTLs) are secreted proteins possessing an amino‐terminal coiled‐coil domain and a carboxyl‐terminal fibrinogen‐like domain and are known as angiogenic factors. Several members of ANGPTLs also regulate lipid metabolism independently of angiogenic effects, but most of their functions during vertebrate development are not demonstrated. To ascertain their developmental functions, we examined the expression patterns of Angptl1, 2, 3, 4, 5, and 7 orthologues during chick development using whole‐mount in situ hybridization. Angptl1 was first detected at embryonic day 3 (E3) in the somite. At E4, Angptl1 was expressed in somite‐derivatives and limb mesenchyme. Angptl2 was first detected at E3 in the hindbrain. At E4, Angptl2 was expressed in neuroepithelium of forebrain and hindbrain and partly in the heart. Angptl3 was first detected at E3 and continued to be expressed in the liver and yolk sac at E4. Angptl4 was first detected at E3 in the somites and liver. At E4, Angptl4 was also observed in the heart. Angptl5 was not detected in these developmental stages. Angptl7 was first detected at E3 in the ectoderm overlying the lenses of the eyes. At E4, Angptl7 was specifically expressed in cornea. These data suggest that each member of the ANGPTL family could be related to angiogenesis during various organogeneses of the developing chick embryo.     

Incrimination of the mosquito,Aedes taeniorhynchus,as the primary vector of heartworm,Dirofilaria immitis,in coastal Yucatan,Mexico

Mosquito collections were carried out on microfilaraemic dogs, positive for Dirofilaria sp., for 18 consecutive nights in the coastal town of Celestún, Yucatan, southeast Mexico, during the rainy season (August) of 2007. A total of 292 female mosquitoes representing 12 species of dipteran Culicidae were collected: Anopheles albimanus (Wiedemann); Anopheles crucians (Wiedemann); Anopheles pseudopunctipennis (Theobald); Culex coronator (Dyar & Knab); Culex interrogator (Dyar & Knab); Culex nigripalpus (Theobald); Culex quinquefasciatus (Say); Culex salinarius (Coquillett); Aedes aegypti (Linnaeus); Aedes scapularis (Rondani); Aedes sollicitans (Walker), and Aedes taeniorhynchus (Wiedemann). Aedes taeniorhynchus and Cx. quinquefasciatus were the species found most commonly feeding on the dogs. Filarial nematodes were observed by microscopy in nine of the mosquito species collected; however, third‐instar larvae were only observed in Ae. taeniorhynchus and An. crucians. Of 76 Ae. taeniorhynchus specimens found positive for Dirofilaria sp. by dissection, 14 were confirmed to be positive for Dirofilaria immitis (Leidy) by polymerase chain reaction (PCR). The resulting infection rate for D. immitis confirmed by PCR (6.2%) is higher than any infection rate for Ae. taeniorhynchus previously reported from the Americas.     

Thompsonia dofleini,a colonial akentrogonid rhizocephalan with dimorphic,ova- or sperm-producing,externae (Crustacea,Cirripedia)

Summary Specimens of the blue swimming crab,Portunus pelagicus, are often infected with many thousands of externae ofThompsonia dofleini, all of which are connected through a common root system within the host crab. The species is unique in that the production of sperm cells takes place within the visceral mass of a small minority of the population of the externae. Spermatogonia are probably introduced by male cyprids into these externae when they are young, and they multiply and develop at the expense of the oocytes which rapidly disintegrate and ultimately disappear. It is assumed that the sperm cells are transferred to the ovary of the ordinary, egg-producing externae through the root system. Shortly after the eggs have been fertilized within the ovary they are transferred to the mantle cavity where they develop into cyprid larvae. The larvae become liberated when the externae drop off and the mantle wall disintegrates.Abbreviations used in the figures a annulus - an antennule - bm basal membrane around ovary - ce compound eye - cg cerebral ganglion - cr connecting root - cy cyprid larva(e) - c1 cuticle 1 - c2 cuticle 2 - do degenerating oocytes - e eggs in early division - ec embryonic cells - em embryos - en endocuticle of host - ep epidermis of host - ex exocuticle of host - hc hemocoelic cavity - m mantle - mc mantle cavity - mcy male cyprid - o ovary - oo oocyte - r rupture in wall of visceral mass - rs root system - sc scar - se spawned eggs - so spent ovary - sp spermatogonia - ss sperm and spermatids - st stalk - tc thickened cuticle of mantle cavity - th thorax - vm visceral mass - y yolk granules     

Quaternary vicariance of tiger beetle,Cicindela chinensis,in Ryukyu,Japan, Taiwan and Korea–China

We show vicariance of Cicindela chinensis in Okinawa, Japan (differentiated within Japan) and Korea–China through construction of Bayesian inference trees by BEAST2. Calibration was done using an assumption of the MRCA expansion of C. chinensis at 1.55 Ma (=geologically obtained formative time of the Ryukyu islands) following the protocol of BEAUti. We derived substitution rates for mitochondrial COI (1.66%/m.y.) and nuclear 28SrRNA (0.109%/m.y.) of analyzed Cicindela. Cicindela ferriei is a sister of C. chinensis, and these two species differentiated from each other at ca. 3 Ma before the expansion of C. chinensis. However, they are not strongly differentiated between Amami‐Oshima and Tokuno‐shima, although they display different color. Vicariance at 1.55 Ma is also recognized between Cicindela batesi in Taiwan and Cicindela aurulenta and virgula in continental China. From the sequence data we obtained, it is also evident that C. c. okinawana recently colonized Ishigaki‐jima from Okinawa‐jima, as did C. batesi in Iriomote‐jima from Taiwan.     

A molecular genetic linkage map of mouse chromosome 18, includingspm,Grl-1, Fim-2/c-fms,andMbp

Restriction endonuclease fragment length variations (RFLV) were detected in mice with DNA probes for myelin basic protein (Mbp), glucocorticoid receptor-1 (Grl-1), and Friend MuLV integration site-2 (Fim-2). RFLV of theMbp gene were found inSacI restriction patterns, RFLV of theGrl-1 gene were found inEcoRV patterns, and RFLV of theFim-2 were found inBglII patterns. A three-point backcross was carried out by the backcross mating (C57BL/KsJ-spm/spm × MOL-MIT)F₁ males × C57BL/KsJ-spm/spm; spm is an autosomal recessive gene causing sphingomyelinosis. From the results,spm, Grl-1, Fim-2, andMbp loci were mapped on chromosome 18, and the following order of genes is proposed, with distances between genes in parentheses: centromere—spm—(7.8 cM)—Grl-1—(7.8 cM)—Fim-2—(39.1 cM)—Mbp—telomere. All laboratory strains and two European subspecies (Mus mus domesticus andM. m. brevirostris) carry theGrl-1 ^a ,Fim-2 ^a , andMbp ^a alleles. In contrast, another wild subspecies from Europe (M. m. musculus) and some Asian subspecies (M. m. molossinus, Chinese mice of wild origin, andM. m. yamashinai) carry theGrl-1 ^b ,Fim-2 ^b , andMbp ^b alleles. Onlycastaneus strains carry the intermediate combination of theGrl-1 ^b ,Fim-2 ^a , andMbp ^b alleles.     

Phylogenetic hypotheses: Cladoniaceae,Stereocaulaceae, Baeomycetaceae,and Icmadophilaceae revisited

Parsimony analyses of SSU rDNA sequences were conducted to examine phylogenetic relationships of selected genera within the families Cladoniaceae, Stereocaulaceae, Icmadophilaceae and Baeomycetaceae (lichen-forming ascomycetes). The analyses included 93 taxa (84 species) representing various groups of ascomycetous fungi. Analyses of the matrix with pre-aligned sequences were performed using heuristic and parsimony ratchet searches, and support values for the same matrix were calculated using parsimony jackknifing. The results support the recognition of the four families. Cladoniaceae are recircumscribed to accommodate Cladia, Cladonia, Heterodea, Metus, Pilophorus, Pycnothelia, Ramalea, Thysanothecium and the newly erected genus Carassea. Myelorrhiza is excluded from the family, while the status of other potential members, Calathaspis, Gymnoderma s.str. and Squamella, remains unresolved. Baeomycetaceae include Baeomyces and Phyllobaeis. Stereocaulaceae include Stereocaulon only, although the status of Muhria is still unclear. Finally, Icmadophilaceae include Dibaeis, Endocena, Knightiella, Icmadophila, Siphula and Thamnolia, while the status of Pseudobaeomyces and Siphulella requires further elucidation. The genus Cladonia appeared to be a polyphyletic assemblage, and accordingly, a new genus Carassea S. Stenroos, gen. nov., represented by C. connexa (Vain.) S. Stenroos, comb. nov., is described. Carassea is most closely related to Pycnothelia and Metus in the Cladoniaceae. Siphula, represented in the present analysis by six species, is not monophyletic, and is in need of reclassification.     

Analysis of Heterozygosity at the PI, TF, PGM1, ACP1, HP, GC, GLO1, C3, and ESDLoci in Pulmonary Tuberculosis Patients Differing in Response to Treatment

Heterozygosity at nine genetic loci (PI, TF, PGM1, ACP1, HP, GC, GLO1, C3, and ESD) was analyzed in pulmonary tuberculosis patients with good (group 1, N= 71) and poor (group 2, N= 35) response to treatment. The observed heterozygosities were compared with the expected values, which were calculated from allele frequencies in a control sample of healthy individuals (N= 328 with all but one locus and 78 with ESD) according to Hardy–Weinberg expectations. The analysis showed that the observed heterozygosities g _l of patients significantly differed from the expected values h _lin the case of four loci (GC, PI, C3, and ACP1). The observed heterozygosity was higher than expected in three cases (PI, C3, and ACP1) and lower then expected (GC) in one case. When data on each individual locus were compared using Fisher's exact test, both groups of patients proved to significantly differ (P _F< 0.05) from the control group in the same four loci. No difference in observed heterozygosity was detected between the two groups of patients. The mean expected heterozygosity was h¯= 0.386 ± 0.00674; the mean observed heterozygosity was g¯ = 0.415 ± 0.02 in group 1, g¯ = 0.402 ± 0.026 in group 2, and g¯ = 0.371 ± 0.00955 in the control group. The ttest did not reveal a significant difference between the mean values of expected observed heterozygosities. Heterozygosity at individual loci, rather than mean heterozygosity, was proposed as an integral nonspecific indicator of the genetic control of a disease, because the former directly implicates individual marker loci in the development of a disorder, whereas effects of individual loci may eliminate each other when mean heterozygosity is computed. Based on the results obtained, a genetic control was assumed for the development of the tuberculosis process in the lungs.     

New species of Alaus Eschscholtz, 1829 (Coleoptera: Elateridae,Agrypninae, Hemirhipini)

Four new species of Alaus Eschscholtz, 1829 are described: A. cinnamomeus n. sp., A. latlpennls n. sp., A. serlceus n. sp. and A. thoracopunctatus n. sp. Three species removed from Chalcolepldlus Eschscholtz, 1829, are transferred to this genus: A. allcll (Pjatakowa, 1941) n. comb., A. haroldl (Candèze, 1878) n.comb. and A. unlcus (Fleutiaux, 1910) n. comb. The characters of external morphology of these seven species and male and female genitalia, when available, are described and illustrated. An identification key for all species of the genus is included: A. allcll (Pjatakowa, 1941) n. comb., A. calcarlpllosus Casari, 1996, A. cinnamomeus n. sp., A. haroldl (Candèze, 1878) n. comb., A. latlpennls n. sp., A. lusclosus (Hope, 1832), A. melanops Leconte, 1863, A. myops (Fabricius, 1801), A. nobllls Sallé, 1855, A. oculatus (Linnaeus, 1758), A. patrlclus (Candèze, 1857), A. plebejus Candèze, 1874, A. serlceus n. sp., A. thoracopunctatus n. sp., A. tricolor (Olivier, 1790), A. unlcus (Fleutiaux, 1910) n. comb., A. veracruzanus Casari, 1996 and A. zunianus Casey, 1893.     

Revisione delle specie: Actinomyces albus,A. chromogenus,A. odorifer,A. thermophylus,A. viridis,A. viridochromogenes,A. hominis,A. innominatus

Riassunto Lo studio comprende una revisione critico-sperimentale della specie Actinomyces albus, della quale vengono considerati come sinonimi circa 30 nomi speeifici, fra i quale A. chromogenus, A. odorifer, A. thermophylus p.p.; della specie é data una diagnosi ed una particolareggiata descrizione.Sono inoltre studiate le specie A. viridis, (= A. viridochromogenus) e A. innominatus, n. nomen. Quest'ultima é preceduta da una breve discussione sulla specie A. homini.

---

Summary Twenty-six strains of Actinomyces albus are studied redescribed from morphological, cultural and biochemical standpoints. Many biological activities of A. chromogenus, A. odorifer and A. thermophilus are in common with other species of the same genus, so that they may be considered for sub-specific, (not specific) differentiation. A discussion on A. farcinicus, A. albidoflavus and A. aureus has been originated from mislabeling as A. albus; the group including the two last named species (flavus group) must be revised. A few strains classified A. farcinicus are in no doubt true A. albus, but this real specific entity remains to be revised from Nocard's strain. A. viridis, for the first time described by Lombardo-Pellegrino, has been redescribed three times as a new species under the same binomial, and the fourth as A. viridochromogenes. A. hominis Bostroem is an uncorrect determination for the species originally described by Waksmann and Curtiss, and it is renamed A. innominatus, the binomial A. (Streptothrix) hominis Auct. being a nomen ambiguum. In conclusion, 30 bionmial are appended in sinonimy to A. albus, including Cladothrix dichotoma Macé (1888) non Cohn, G. invulnerabilis Acosta et G. Rossi, C. odorifera Rullm. Actinomyces chromogenus Gasp., A. thermophilus Auct., p.p., A. (Streptothrix) Sanninii (Cif.) Westerd., A. Almquisti Duché, A. Gougeroti Duché, and so on.

     

Linkage disequilibrium of HLA-SB1 with the HLA-A1, B8, DR3, SCO1 and of HLA-SB4 with the HLA-A26, Bw38, Dw10, DR4, SC21 extended haplotypes

Homozygous typing cells from 13 normal HLA-A1, B8, Dw3, DR3 and five normal HLA-A26, Bw38, Dw10, DR4 individuals were typed for the following markers: HLA-SB, MB, MT; complement proteins BF, C2, C4A, C4B; and GLO. Ninety-one percent of A1, B8, Dw3, DR3 homozygous individuals (HI) tested were homozygous for BF ^* S, C2 ^* C, C4A ^* QO, and C4B ^*1 (SCO1 complotype), which indicates that the SCO1 complotype is in linkage disequilibrium with the A1, B8, DR3 haplotype in randomly selected normal populations. Sixty-seven percent of HLA-A1, B8, Dw3, DR3, SCO1 positive HI also expressed SB1; since the frequency of SB 1 in random Caucasian populations is 11.2%, this finding indicates that SB1 is in linkage disequilibrium with the A1, B8, DR3, SCO1 extended haplotype. All HI with the A26, Bw38, Dw10, DR4 haplotype were homozygous for both SC21 and SB4, suggesting that SC21 and SB4 should be included in the A26, Bw38, Dw10, DR4 extended haplotype. On the other hand, neither of the GLO markers were found in association with either haplotype. The results of this study indicate that HLA-SB is included in some extended haplotypes and may be important in these markers for diseases such as insulin-dependent diabetes mellitus. This study also demonstrated an apparent influence of HLA-SB on primary mixed lymphocyte culture (MLC) responses. The mean relative response of primary MLCs between individuals matched for HLA-A, B, D, DR, MB and MT but not SB was 40% of that for the MLCs with mismatched HLA-D, significantly higher than the MLCs matched for all HLA and complotypes.     

Tracer flow,permeability, and partial conductance

Summary It is often not possible to evaluate a permeability coefficient for net flowP from the small flows produced by physiological gradients of concentration or electrical potential. The common use of a tracer permeability coefficientP ^x for this purpose, under the assumption thatP ^x =P, requires that the species be transported passively, and that there be no significant coupling between its flow and that of other chemical species, and between the flows of its tracer and abundant isotopes (isotope interaction). These conditions are often not satisfied. However, for passive transport in the absence of coupling of flows of different chemical species the measurement of tracer flow at two values of electrical potential difference evaluates (P ^x /P) and thusP. In the presence of coupling of flows of different chemical species, although these measurements no longer evaluateP, they evaluate the partial conductanceG. A graphical method of evaluating (P ^x /P),P andG is presented.
