We found an association between tonsillectomized patients and subsequent appendicitis. We also observed that MALTectomy significantly decreased secretory IgA levels in serum of patients, being this decrease more pronounced when both operations (tonsillectomy and appendectomy) had been performed. The elevated humoral responses detected previously by us in BALB/c mice immunized with Kudoa sp. pseudocyst extracts and the high IgG1 and IgE levels induced by the oral administration of Kudoa sp. pseudocysts to BALB/c mice showed the possible immunopathological effects in man from the ingestion of Kudoa sp. infected fish. We use the ELISA method to investigate the possible relationship between MALTectomy (tonsillectomy and appendectomy) and specific antibody levels to Kudoa sp. Both anti-Kudoa sp. specific antibody levels and the number of patients that recognized Kudoa sp. antigens were greater in tonsillectomy patients when compared to the control and the other studied groups (appendectomized and appendectomized + tonsillectomies patients). Tonsillectomy was associated to a switch in the class of immunoglobulins involved in these responses and these responses may be abrogated by appendectomy. Tonsils and appendix may respond in different ways to Kudoa sp. antigens and these different reactions may be involved in some immunopathological reactions.  相似文献

Percolomonads (Heterolobosea) are aquatic heterotrophic flagellates frequently found in saline waters up to hypersaline environments. We isolated and cultivated seven strains of percolomonad flagellates from marine waters and sediments as well as from a hypersaline inland lake in the Atacama Desert. Morphological characterizations, comprising light and scanning electron microscopy, revealed only slight differences between the strains mainly limited to the cell shape, length of flagella, and length of the ventral feeding groove. Phylogenetic analyses of the 18S and 28S rDNA genes showed the formation of three fully supported clades within the Percolomonadida: the Percolomonadidae, the Barbeliidae fam. nov. and the Lulaidae fam. nov. We describe two new families (Barbeliidae fam. nov., Lulaidae fam. nov.), a new genus (Nonamonas gen. nov.), and five new species (Percolomonas adaptabilis sp. nov., Lula levis sp. nov., Barbelia pacifica sp. nov., Nonamonas montiensis gen. et sp. nov., Nonamonas santamariensis gen. et sp. nov.). Salinity experiments showed that P. adaptabilis sp. nov. from the Atlantic was better adapted to high salinities than all other investigated strains. Moreover, comparisons of our cultivation-based approach with environmental sequencing studies showed that P. adaptabilis sp. nov. seems to be globally distributed in marine surface waters while other species seem to be more locally restricted.  相似文献

Although aquatic caterpillars are a globally rare lifestyle, we have found them in multiple, independent lineages of the endemic moth genus Hyposmocoma across all of the Hawaiian Islands with flowing water. We formally describe 11 new species of Hyposmocoma that belong to four different larval case types: cone, bugle, medium burrito, and large burrito: Hyposmocoma kahamanoa sp. nov. from Oahu Island, Hyposmocoma kamakou sp. nov. from Molokai Island, Hyposmocoma kahaiao sp. nov. , Hyposmocoma waihohonu sp. nov. , and Hyposmocoma moopalikea sp. nov. from Maui Island, and Hyposmocoma aumakuawai sp. nov. , Hyposmocoma eepawai sp. nov. , Hyposmocoma ipowainui sp. nov. , Hyposmocoma kawaikoi sp. nov. , Hyposmocoma uhauiole sp. nov. , and Hyposmocoma wailua sp. nov. from Kauai Island. We also illustrate and describe in detail the aquatic case‐bearing larva of Hyposmocoma kahamanoa. Despite having similar ecologies as algae and lichen grazers at and below the water line of streams, prior research indicates that species with each case type constitute an independent lineage, with terrestrial sister taxa, and therefore the different groups of species bearing unique case types each represent an independent aquatic invasion. The case‐bearing larvae often occur sympatrically, and on Kauai even species with similar case‐types occur together, suggesting complex patterns of speciation and either past periods of isolation or sympatric speciation. Phylogenetic analysis of 2243 base pairs from two nuclear and one mitochondrial gene for 18 species confirm that each species is endemic to a single volcano, and that morphological divergence within case‐types has not been dramatic. Diversification has been complex, and superficially similar case type lineages are not all monophyletic. Kauai, the oldest but smallest of the major high islands, supports more species in the aquatic guild than any other island, thus island age, rather than size, may be important in generating diversity in this group. © 2011 The Linnean Society of London, Zoological Journal of the Linnean Society, 2011, 162 , 15–42.  相似文献

Seven new species of Penicillium Link ex Fries and a new variety of Penicillium novae-caledoniae Smith are described and illustrated. Four of them have been recovered from the air in Madrid, Spain, one from beech leaves litter in a beech forest near Nancy, France, two from sandy soils in Madrid, and one from an andosol in the Spanish Province of Navarra. They clearly differ from all species of the genus described so far and are, therefore, described and proposed as new taxa: Penicillium turolense sp. nov., Penicillium murcianum sp. nov., Penicillium ovetense sp. nov., Penicillium asturianum sp. nov., Penicillium onobense sp. nov., Penicillium castellonense sp. nov., Penicillium aragonense sp. nov., and Penicillium novae-caledoniae Smith, var. album var. nov.  相似文献

Synopsis. Facieplatycauda pratti gen. n., sp. n. and Myxobolus kozloffi sp. n., from the Klamath Lake sucker, Catostomus luxatus (Cope), are described. The new genus is placed in the family Myxobolidae between Henneguya and Myxobolus. The spore valves beyond the sporoplasmic space are broad and long but not attenuated as an inverted triangle as in certain species of Myxobolus with tails, or of Henneguya with sometimes bifurcated tails. An organism resembling Myxobolus insidiosus (Wyatt & Pratt) was found in the muscle of the body of Salmo clarki (Richardson). Differences in spore structure and site of infection suggest this is a subspecies of the previous form which should be designated Myxobolus insidiosus clarki. A previously unreported species of Myxobolus from Cottus aleuticus (Gilbert) is also described.  相似文献

Coral reefs are renowned as complex ecosystems with an extremely large biodiversity. Parasite-host relationships contribute substantially to this, but are poorly known. We describe the results of a study in which approximately 60,000 corals were searched for parasitic Leptoconchus snails (Gastropoda: Coralliophilidae) in Indo-West Pacific waters of Egypt, the Maldives, Thailand, Palau and Indonesia. We discovered an adaptive radiation of 14 snail species, each of which lives in species-specific association with one or more of 24 mushroom coral species. The 14 snail species are described as new to science under the names Leptoconchus inactiniformis sp. nov., L. inalbechi sp. nov., L. incrassa sp. nov., L. incycloseris sp. nov., L. infungites sp. nov., L. ingrandifungi sp. nov., L. ingranulosa sp. nov., L. inlimax sp. nov., L. inpileus sp. nov., L. inpleuractis sp. nov., L. inscruposa sp. nov., L. inscutaria sp. nov., L. intalpina sp. nov., and L. massini sp. nov. Their separation is based on indisputable molecular differences, whereas the rudimentary shell characters or impoverished anatomical details do not allow identification. The coral hosts also serve to distinguish the snail species, as none of the former was found to contain more than one of the latter. The complexity of coral reefs is still underrated, as is shown here by the application of DNA taxonomy as an indispensable approach to unravel cryptic radiations, which must be known in order to understand the functioning of the ecosystem.  相似文献

Eight new and one less known nematode species are described from Vöring Plateau at 970 m to 1426 m depth and adjacent deep-sea plain at 3062 m depth in the Norwegian Sea: Actinonema grafi sp. nov., Desmodora pilosa Ditlevsen, 1926, Leptolaimus meyer-reili sp. nov., Tarvaia heegeri sp. nov., Diplopeltoides linkei sp. nov., Diplopeltis bathmanni sp. nov., Southerniella nojii sp. nov, Pararaeolaimus rumohri sp. nov. and Theristus altenbachi sp. nov. Differential diagnoses to the eight new species are given. Actinonema grafi, Leptolaimus meyer-reili and Theristus altenbachi are frequently found on Vöring Plateau and belong to the most dominant species, whereas Desmodora pilosa and Pararaeolaimus rumohri are dominant species at few sites only. The other species occur sporadically, in few numbers, and belong — as do Pararaeolaimus rumohri — to seldomly reported nematode genera.Contribution No. 111 from Sonderforschungsbereich 313 der Universität Kiel, Germany.  相似文献

The Cossidae are an economically important family of moths consisting of six subfamilies and more than 700 species globally. Their larvae are often of serious concern to forestry and horticulture in that they are known to bore in the branches and trunks of a wide range of trees and shrubs. Cossulinae is one of the six subfamilies of Cossidae and is restricted to the New World. As a result of this revision, the Costa Rican Cossulinae has been found to consist of five genera and 18 species. The phylogenetic relationships of all Cossulinae genera were analysed using the computer programs WinClada and NONA. Glandular organs new to Cossidae and the Lepidoptera have also been discovered. Four genera, Biocellata gen. nov. , Magulacra gen. nov. , Simplicivalva gen. nov. and Spinulata gen. nov. , and the following nine species are described as new: Biocellata bifida sp. nov. , Biocellata davisorum sp. nov. , Cossula buspina sp. nov. , Cossula duplexata sp. nov. , Cossula longirostrum sp. nov. , Cossula minutiloba sp. nov. , Simplicivalva ampliophilobia sp. nov. , Spinulata oblongata sp. nov. and Spinulata quasivinnea sp. nov. © 2008 The Linnean Society of London, Zoological Journal of the Linnean Society, 2008, 154 , 222–277.  相似文献
