ectoparasite fauna of rodents and shrews from four habitats in kuala lumpur and the states of selangor and negeri sembilan, malaysia and its public health significance.a total of 204 rodents comprising 14 host species from four different habitats were examined. nine rodent species were trapped from the forest and another five species were trapped from the coastal, rice field and urban habitats. rattus rattus diardii (67%) was the predominant rodent species examined. fifty six (47.3%) rodents and shrews were found to be infested with at least one of the 20 species of ectoparasite recovered. mites belonging to the family trombiculidae were the predominant ectopa ...200920237444
isolation and molecular characterization of leptospira interrogans and leptospira borgpetersenii isolates from the urban rat populations of kuala lumpur, malaysia.rats are considered the principal maintenance hosts of leptospira. the objectives of this study were isolation and identification of leptospira serovars circulating among urban rat populations in kuala lumpur. three hundred urban rats (73% rattus rattus and 27% r. norvegicus) from three different sites were trapped. twenty cultures were positive for leptospira using dark-field microscopy. r. rattus was the dominant carrier (70%). polymerase chain reaction (pcr) confirmed that all isolates were p ...201323358635
helminth communities from two urban rat populations in kuala lumpur, malaysia.the prevalence of parasitic infections among commensal animals such as black and brown rats in many tropical countries is high and in comparison with studies on rodents in temperate climates, little is known about the community structure of their parasites. rodent borne parasites pose threats to human health since people living in close proximity to rodent populations can be exposed to infection.201222397763
