Canine parvovirus 2 (CPV-2) was first identified in 1978, and is responsible for classic parvoviral enteritis. Despite the widespread vaccination of domestic carnivores, CPVs have remained important pathogens of domestic and wild carnivores. In this study, we isolated CPV-2 from Tibetan mastiffs and performed a global analysis of the complete VP2 gene sequences of CPV-2 strains in China. Six is...
Genetic polymorphism was determined among 13 isolates of Taenia solium from various regions using PCR-amplified sequences of 2 mitochondrial genes: cytochrome c oxidase subunit 1 and cytochrome b. The 2 phylogenies obtained were similar to each other regardless of the genes examined. The isolates from Asia (China, Thailand, Irian Jaya and India) formed a single cluster, whereas the isolates fro...
To determine the phage types (PT) of Salmonella enteritidis found in Thailand and to clarify the potential for human infection by S. enteritidis in broiler chicken meat, human and poultry isolates taken from Thailand between 1990 and 1997 were phage typed and analyzed by pulsed-field gel electrophoresis (PFGE). Ten different PT were found among the 302 isolates phage typed, with PT 4 being the ...
The Paridris nephta group is revised (Hymenoptera: Platygastridae). Fifteen species are described, 14 of which are new: Paridris atroxTalamas, sp. n.(Yunnan Province, China), Paridris bununTalamas, sp. n.(Taiwan), Paridris ferusTalamas, sp. n.(Thailand), Paridris kagemonoTalamas, sp. n.(Japan), Paridris minatorTalamas, sp. n.(Laos, Thailand), Paridris mystaxTalamas, sp. n.(Laos, Thailand), Pari...
پژمردگی فوزاریومی خربزه و طالبی با عامل fusarium oxysporum f. sp. melonis از بیماری های مهم قارچی در مناطق رشد این گیاهان می باشد. جدایه های f. oxysporum از گیاهان و خاک ریزوسفر متعلق به پنج استان مهم تولیدکننده ی خربزه و طالبی جداسازی شد و بر پایه ی بیماری زایی در ارقام افتراقی، گروه های سازگاری رویشی (vegetative compatibility groups)، توالی سنجی ناحیه ی جداکننده ی بین ژنی دی اِن اِی ریبوزومی (n...
Molecular genetic approaches typically detect recombination in microbes regardless of assumed asexuality. However, genetic data have shown the AIDS-associated pathogen Penicillium marneffei to have extensive spatial genetic structure at local and regional scales, and although there has been some genetic evidence that a sexual cycle is possible, this haploid fungus is thought to be genetically, ...
The cytochrome oxidase subunit I (COXI) gene sequences of three recent (20072008) clinical Plasmodium knowlesi isolates from Klang Valley, peninsular Malaysia, were determined and compared with those of older (1960’s) peninsular Malaysia, recent isolates from Sarawak (on Borneo Island), and an isolate from Thailand. Multiple alignment of the sequences showed that the three clinical isolates wer...
Phylogeny and biogeography of Lentinula, which includes cultivated shiitake mushrooms, were investigated using parsimony analyses of an expanded nuclear ribosomal DNA dataset. Lentinula occurs in the New World as well as Asia and Australasia. The Asian–Australasian Lentinula populations appear to form a clade, but species limits within this group are controversial. We refer to the entire Asian–...
Five new species of Myrsidea are described from Babblers (Passeriformes: Timaliidae). The new species and their type hosts are: Myrsidea cheni ex Alcippe morrisonia from China; M. macronoi ex Macronous gularis from Sarawak and Thailand; M. argentauris ex Leiothrix argentauris from China and Thailand; M. dukguni ex Stachyris striolata from China; and M. falcatae ex Ptilocichla falcata from the P...
OBJECTIVE Salmonella enterica serovar Kedougou is among the top 10 serovars reported in northern Thailand. The objective of this study was to identify risk factors associated with Salmonella Kedougou infection in Thailand and to compare the molecular types and antimicrobial resistance with Salmonella Kedougou isolates of human origin from United States and of animal origin from the United Kingd...
