Endangered Zoonotic Fungal Species from Chicken (Gallus gallus domestics).

Endangered Zoonotic Fungal Species from Chicken (Gallus gallus domestics). Med Mycol J. 2019;60(2):45-49 Authors: Yamaguchi S Abstract Lophophyton gallinae (Microsporum gallinae) is a zoophilic fungus that causes ringworm in chickens and related species, and occasionally in humans. There are 45 human cases worldwide including a Japanese case from Okinawa in 2009. After the finding of the human L. gallinae case, 793 chickens in Japan, including 293 from the mainland and 500 from the Nansei Island areas, were investigated to determine the prevalence of dermatophytes and their related fungal species. The survey was carried out from December 2008 to March 2013. Various dermatophytes and related fungal species were isolated from the studied chickens, with a prevalence of 24.6%. In total, 224 dermatophytes and related species were isolated in the survey. The most commonly isolated species included, in descending order of frequency, Arthroderma multifidum, Aphanoascus terreus, and Chrysosporium spp. Ar. multifidum and Ap. terreus have no record of pathogenicity, and the present isolates of Chrysosporium spp. were not matched to pathogenic Chrysosporium spp. based on the ITS rDNA sequences. Interestingly, an L. gallinae isolate was detected in a male 10-month-old shamo (fighting cock) from the main island. Furthermore, one strain of Arthroderma simii was also isolated as the second record in Japan following that from an imported chimpanzee. Although L. gallinae a...

In this study, we found two species, Milnesium pacificum sp. nov. and Milnesium tardigradum Doyère, 1840, from three southern islands and two cold regions in Japan, respectively. Milnesium pacificum sp. nov., having dorsal sculpturing, exhibits an early positive change in claw configuration. On the other hand, M. tardigradum s.s. from Japan has an early negative claw configuration change, as has been reported in a recent study on the neotype population of this species. We performed DNA barcoding for both species, which indicated that M. pacificum sp. nov. has a close affinity with an undescribed Milnesium species co...

Abstract Having been reported in 1898 for the first time from Japanese waters, the lineid heteronemertean Lineus longifissus auct. is known to inhabit tidal flats under the influence of the warm Kuroshio Current along the coasts of Honshu and southwestward, characteristically with a uniformly raisin-colored to black body lacking a caudal cirrus. The taxonomic identity of the Japanese L. longifissus auct. has been questioned by specialists because of some obvious morphological differences between Lineus longifissus (Hubrecht, 1887) s.str. (now in Heteronemertes Chernyshev, 1995), originally described from the suban...

Abstract Batoidea (rays and skates) is a monophyletic subgroup of elasmobranchs that diverged from the common ancestor with Selachii (sharks) about 270 Mya. A larger number of batoids can adapt to low-salinity environments, in contrast to sharks, which are mostly stenohaline marine species. Among osmoregulatory organs of elasmobranchs, the kidney is known to be dedicated to urea retention in ureosmotic cartilaginous fishes. However, we know little regarding urea reabsorbing mechanisms in the kidney of batoids. Here, we performed physiological and histological investigations on the nephrons in the red stingray (Hem...

Abstract Sinogastromyzon sichangensis is a hillstream loach endemic to the upper Yangtze River, China. It is unclear whether this fish lives in a very restricted area or may be dispersed over a long distance. In the present study spatial connectivity of populations of S. sichangensis was investigated based on 343 individuals collected from 12 sites of Chishui River and employing 22 microsatellite loci. The results of genetic diversity analysis showed that observed heterozygosity (HO) and polymorphism information content (PIC) ranged from 0.5653 to 0.6999 and 0.8513 to 0.8819, respectively. Population structure ana...

Abstract Condition-specific competition is a phenomenon by which inter-specific competitive dominance changes as a result of environment, and is an important factor determining species distribution. Congeneric charrs in Hokkaido, Japan, provide one of the best examples of condition-specific competition: Dolly Varden, Salvelinus malma, often dominate in cold streams (6-8°C), whereas white-spotted charr, Salvelinus leucomaenis, dominate in warmer streams (> 10°C). While past laboratory and field experiments have demonstrated the great advantage of white-spotted charr at higher water temperatures, the adva...

Abstract The genetic diversity of the genus Ligidium in Hokkaido and Niigata, northern Japan, was investigated by analyzing the cytochrome c oxidase subunit 1 (CO1) region in the mitochondrial DNA (mtDNA). The genetic diversity in Hokkaido was much lower than that in Niigata. Nine different operational taxonomic units (OTUs) were identified. Only a single OTU, most likely Ligidium japonicum, was found in Hokkaido, whereas all nine OTUs were found in Niigata. Using the mtDNA evolutionary rate determined for the marine invertebrate Haptosquilla pulchella (Miers, 1880), population expansion for OTU1 in Hokkaido was e...

Abstract Sika deer (Cervus nippon) in Japan are classified into southern and northern groups. However, previous studies primarily relied on maternally inherited mitochondrial DNA (mtDNA). The paternally inherited Y-chromosome is useful for analyzing the contribution of males to the population genetic history of sika deer. In total, approximately 16 kb of partial sequences of four Y-chromosomal genes, Y-linked, sex-determining region Y, DEAD-box helicase 3 Y-linked, and Zinc finger protein Y-linked, were sequenced to investigate intraspecific variation. As a result, we identified nine intronic single nucleotide pol...
