antimicrobial resistance of salmonella spp. isolates and heavy metal traces from rodent meat purchased from roadside markets, central thailand.although game meat consumption is widespread across the globe, involving a great diversity of species in very different ecological and sociocultural environments, the safety of wild meat products is rarely assessed routinely. we conducted a survey to evaluate the safety of two rodents products (rattus tanezumi and bandicota indica) purchased from roadside markets in central thailand. total aerobic bacteria and escherichia coli counts measured were above thai poultry product standards for 83.3% a ...201931140877

evaluation of the role of rats as reservoir hosts for fishborne zoonotic trematodes in two endemic northern vietnam fish farms.fishborne zoonotic trematodes (fzts) pose a food safety risk for the aquaculture industry in vietnam. the risk of being infected from eating raw fish applies not only to humans but also to domestic animals which can serve as reservoir hosts in fish farms. the role of rodents, commonly found in fish farms, as reservoir hosts has not been adequately evaluated. to study this question, commensal and rice field rats were collected from fish farms in nghia lac and nghia phu communes, nam dinh province ...201222592535
zoonotic helminthiases in rodents (bandicota indica, bandicota savilei, and leopoldamys edwardsi) from vientiane capital, lao pdr.zoonotic helminths of three rodent species, bandicota indiaca, bandicota savilei, and leopoldamys edwardsi, were investigated in vientiane capital, lao pdr. a total of 310 rodents were infected with 11 species of helminth parasites. there were 168 (54.2%) of 310 rodents infected with zoonotic helminths. from our results, there are six recorded zoonotic helminth species, and the highest prevalence was exhibited by raillietina sp. (30.7%), followed by hymenolepis diminuta (17.7%), hymenolepis nana ...202032959774
low prevalence of leptospira carriage in rodents in leptospirosis-endemic northeastern thailand.leptospirosis is a neglected zoonotic disease affecting mostly the world's tropical regions. the rural people of northeastern thailand suffer from a large number of leptospirosis infections, and their abundant rice fields are optimal rodent habitats. to evaluate the contribution of diversity and carriage rate of pathogenic leptospira in rodent reservoirs to leptospirosis incidence, we surveyed rodents, between 2011 and 2012, in four provinces in northeastern thailand with the highest incidence r ...202033008058
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
complete mitochondrial genome of the greater bandicoot rat bandicota indica (rodentia: muridae).the complete mitochondrial genome of the greater bandicoot rat (bandicota indica) was first sequenced and characterized. the genome was 16 326 bp in length, the composition and arrangement of its genes were analogous to other rodents. to confirm the phylogenetic position of b. indica, the mitochondrial nucleotide sequence data of other 20 rodentia species were used to construct phylogenetic tree by maximum likelihood. phylogenetic analysis demonstrated that genera bandicota and rattus were siste ...201626471207
widespread rickettsia spp. infections in ticks (acari: ixodoidea) in taiwan.ticks are second to mosquitoes as the most important disease vectors, and recent decades have witnessed the emergence of many novel tick-borne rickettsial diseases, but systematic surveys of ticks and tick-borne rickettsioses are generally lacking in asia. we collected and identified ticks from small mammal hosts between 2006 and 2010 in different parts of taiwan. rickettsia spp. infections in ticks were identified by targeting ompb and glta genes with nested polymerase chain reaction. in total, ...201526336223
how important are rats as vectors of leptospirosis in the mekong delta of vietnam?leptospirosis is a zoonosis known to be endemic in the mekong delta of vietnam, even though clinical reports are uncommon. we investigated leptospira infection in rats purchased in food markets during the rainy season (october) (n=150), as well as those trapped during the dry season (february-march) (n=125) in the region using rt-pcr for the lipl32 gene, confirmed by 16s rrna, as well as by the microscopic agglutination test (mat). results were compared with the serovar distribution of human cas ...201525629781
fragmented mitochondrial genomes of the rat lice, polyplax asiatica and polyplax spinulosa: intra-genus variation in fragmentation pattern and a possible link between the extent of fragmentation and the length of life cycle.blood-sucking lice (suborder anoplura) parasitize eutherian mammals with 67% of the 540 described species found on rodents. the five species of blood-sucking lice that infest humans and pigs have fragmented mitochondrial genomes and differ substantially in the extent of fragmentation. to understand whether, or not, any life-history factors are linked to such variation, we sequenced the mt genomes of polyplax asiatica and polyplax spinulosa, collected from the greater bandicoot rat, bandicota ind ...201424438034
prevalence of zoonotic bartonella species among rodents and shrews in thailand.we investigated the prevalence of bartonella species in 10 rodent and one shrew species in thailand. from february 2008 to may 2010, a total of 375 small animals were captured in 9 provinces in thailand. bartonella strains were isolated from 57 rodents (54 from rattus species and 3 from bandicota indica) and one shrew (suncus murinus) in 7 of the 9 provinces, and identified to the species level. sequence analysis of the citrate synthase and rna polymerase β subunit genes identified the 58 isolat ...201424393304

observations on commensal rats and their status to plague in bombay.the distribution pattern of various types of commensal rodents in bombay city reveals that bandicota bengalensis constitutes the predominant commensal rodent species followed by r. rattus and rattus norvegicus. apart from these three types, bandicota indica, m. musculus and an insectivore (suncus murinus) are the three species of commensal small mammals that are frequently encountered in or near human habitations. these small mammals are prevalent throughout the year and their percentage distrib ...19883221091
integrative taxonomic approach of trypanosomes in the blood of rodents and soricids in asian countries, with the description of three new species.trypanosoma lewisi (kinetoplastea: trypanosomatida: trypanosomatidae) with a cosmopolitan distribution is the type species of the subgenus herpetosoma, which includes ca. 50 nominal species isolated mainly from rodents. since members of herpetosoma in different host species have an almost identical morphology of bloodstream forms, these trypanosomes are referred to as 't. lewisi-like', and the molecular genetic characterization of each species is necessary to verify their taxonomy. in the presen ...201930353232
[(acari: trombiculidae) (the infestation of small mammals in south-eastern vietnam with harvest mites (acari: trombiculidae))].this investigation was conducted in three provinces of southern vietnam in september-october 2011. a total of 257 small mammals of 11 species were caught; among them 120 rodents were infected with harvest mites of 8 species (trom- biculidac). about 4000 mites of nearly 1200 identified species were collected from the small mammals. 17 species of harvest mites were identified. walchia lupella, leptotrombidium deliense, walchia kritochaeta, and walchia micropelta predominated in the collections. mo ...201730721614
