identification of novel rosavirus species that infects diverse rodent species and causes multisystemic dissemination in mouse model.while novel picornaviruses are being discovered in rodents, their host range and pathogenicity are largely unknown. we identified two novel picornaviruses, rosavirus b from the street rat, norway rat, and rosavirus c from five different wild rat species (chestnut spiny rat, greater bandicoot rat, indochinese forest rat, roof rat and coxing's white-bellied rat) in china. analysis of 13 complete genome sequences showed that "rosavirus b" and "rosavirus c" represent two potentially novel picornavir ...201627737017
[effects of high-fiber diet on timing of behaviors in bandicota indica].food resources and energy budget affect the behaviors and time budgets of animals. to clarify the effects of a high-fiber diet on greater bandicoot rat (bandicota indica) behavior, we compared b. indica under a high-fiber diet and a standard rat diet using video monitoring. our results show that b. indica are mainly active and feed at night, typical of nocturnal animals. a high-fiber diet resulted in a longer time to feed and become active at night and reduced the time spent feeding during the d ...201121509972
angiostrongylus infections in rats and snails in northeast thailand.a survey of angiostrongylus infections in rats and snails was carried out in the provinces of ubon ratchathani, udon thani. kalasin, chaiyaphum and khon kaen in northeast thailand. only two rattus norvegicus (3.8%) and one bandicota indica (1.4%) out of 151 r. rattus, 52 r. norvegicus and 69 b. indica examined were infected with adult lung worms. all worms recovered were a. cantonensis. prevalence of infection in 423 pila polita was 0.9% while all of 77 p. ampullacea were negative for larvae. in ...19979656375
perspectives on applied spatial analysis to animal health: a case of rodents in thailand.geographic information systems (gis) and remote sensing have been increasingly used in ecology and epidemiology, providing a spatial approach for animal health issues. recent development of earth environmental satellites--i.e., their growing number, improving sensor resolutions and capabilities--has offered new opportunities to delineate possible habitats and understand animals and associated parasites in their environment, by identifying the nature and structure of land use, hydrological networ ...200617135491
high prevalence of rat hepatitis e virus in wild rats in china.serum samples from a total of 713 wild rats captured in zhanjiang city in china from december 2011 to september 2012 were investigated for the prevalence of rat hepatitis e virus (hev) by exploring rat hev-specific antibodies and rna. by an elisa based on recombinant rat hev-like particles (hev-lps), 23.3% (166/713) of the rats were positive for anti-hev igg, and 8.3% (59/713) were positive for anti-hev igm. the igg-positive rates in rattus norvegicus, bandicota indica, rattus flavipectus, rattu ...201323623690
molecular characterization of the ribosomal dna unit of sarcocystis singaporensis, sarcocystis zamani and sarcocystis zuoi from rodents in thailand.sarcocystis species are heteroxenous cyst-forming coccidian protozoan parasites with a wide host range, including rodents. in this study, sarcocystis spp. samples were isolated from bandicota indica, rattus argentiventer, r. tiomanicus and r. norvegicus across five provinces of thailand. two major groups of sarcocystis cysts were determined in this study: large and small cysts. by sequence comparisons and phylogenetic analyses based on the partial sequences of 28s ribosomal dna, the large cysts ...201728701623
First provincial survey of Angiostrongylus cantonensis in Guangdong Province, China.The rat lungworm Angiostrongylus cantonensis is a zoonotic nematode with a wide distribution. We report the first provincial survey of the prevalence of A. cantonensis infection among wild rodents and snails in Guangdong Province, China. A total of 2929 Pomacea canaliculata and 1354 Achatina fulica were collected from fields in 22 survey sites with a larval infection rates ranging from 0-26.6% to 0-45.4%. In addition, 114 Cipangopaludina sp and 252 Bellamya sp were bought from markets; larvae we ...201121906215
the distribution and diversity of bartonella species in rodents and their ectoparasites across thailand.our study highlights the surveillance of bartonella species among rodents and their associated ectoparasites (ticks, fleas, lice, and mites) in several regions across thailand. a total of 619 rodents and 554 pooled ectoparasites (287 mite pools, 62 flea pools, 35 louse pools, and 170 tick pools) were collected from 8 provinces within 4 regions of thailand. bandicota indica (279), rattus rattus (163), and r. exulans (96) were the most prevalent species of rats collected in this study. real-time p ...201526484537
