high prevalence of rodent-borne bartonella spp. in urbanizing environments in sarawak, malaysian borneo.rodents are the most prominent animal host of bartonella spp., which are associated with an increasing number of human diseases worldwide. many rodent species thrive in urban environments and live in close contact with people, which can lead to an increased human risk of infection from rodent-borne pathogens. in this study, we explored the prevalence and distribution of bartonella spp. in rodents in urban, developing, and rural environments surrounding a growing city in sarawak, malaysian borneo ...201930526734
detection of borreliaburgdorferi sensu lato and relapsing fever borrelia in feeding ixodes ticks and rodents in sarawak, malaysia: new geographical records of borrelia yangtzensis and borrelia miyamotoi.members of the borrelia burgdorferi sensu lato (bbsl) complex are etiological agents of lyme disease (ld), and borrelia miyamotoi is one of the relapsing fever borrelia (rfb). despite the serological evidence of ld in malaysia, there has been no report from sarawak, malaysian borneo. thus, this study aimed to detect and characterize borrelia in rodents and ixodes ticks from primary forests and an oil palm (op) plantation in sarawak. borrelia yangtzensis (a member of the bbsl complex) was detecte ...202033076567
molecular characterization of pathogenic leptospira sp. in small mammals captured from the human leptospirosis suspected areas of selangor state, malaysia.leptospirosis is caused by the spirochetal bacterium leptospira of which rodents are considered the most important reservoir. this study aims to determine and characterize virulent leptospira species among rodents and small mammals found in human settlements and recreational spots within the hulu langat and gombak districts of selangor, malaysia; regions that frequently report probable human leptospirosis cases. molecular analysis revealed an overall leptospira detection rate of 14.3% among the ...201830145261
association of rodent-borne leptospira spp. with urban environments in malaysian borneo.although leptospirosis is traditionally considered a disease of rural, agricultural and flooded environments, leptospira spp. are found in a range of habitats and infect numerous host species, with rodents among the most significant reservoirs and vectors. to explore the local ecology of leptospira spp. in a city experiencing rapid urbanization, we assessed leptospira prevalence in rodents from three locations in malaysian borneo with differing levels of anthropogenic influence: 1) high but stab ...201930811387
schistosoma malayensis n. sp.: a schistosoma japonicum-complex schistosome from peninsular malaysia.schistosoma malayensis n. sp., a member of the schistosoma japonicum complex is described from rattus muelleri in peninsular malaysia and 2 strains are characterized. the only morphological differences noted among adults from natural hosts were that s. malayensis are in general smaller than s. mekongi and s. japonicum. but these differences may be the result of host-induced variations and therefore are of little taxonomic value. to minimize the effects of host-induced variations, adult worms rec ...19883379527
a preliminary field survey of ectoparasites of rodents in urban park, sarawak, malaysian borneo.a survey of ectoparasites was carried out during eco-zoonoses expedition in bukit aup jubilee park (bajp), sibu, sarawak, malaysian borneo from 5(th) to 9(th) june 2008. a total of nine individuals comprising two species of rodents were captured. the species of rodents screened for ectoparasites were sundamys muelleri and callosciurus notatus. four genera and six species of ectoparasites were collected, namely, ixodes granulatus, ixodes sp., laelaps sedlaceki, laelaps nuttalli, hoplopleura dissi ...201324189685
helminth infections in small mammals from ulu gombak forest reserve and the risk to human health.a survey for small mammal parasites carried out in a secondary forest of ulu gombak, selangor, peninsula malaysia yielded the following animals: rattus bowersi (7), rattus tiomanicus jalorensis (2), maxomys rajah (12), maxoyms whiteheadi (3), leopoldamys sabanus(13), sundamys muelleri(10), lariscus insignis (1), sundasciurus tenuis (1) and tupaia glis (2). the following nematodes: capillaria hepatica, hepatojarakus malayae, trichostrongylus sp. and streptopharagus sp., the following cestodes: hy ...200516883287
experimental infection of rattus sabanus and rattus muelleri with subperiodic brugia malayi.r. sabanus and r. muelleri are very common in the lowland forests of malaysia. in nature they are infected with breinlia sp. and d. ramachandrani. in an attempt to determine whether they are also susceptible to subperiodic b. malayi and thereby being potential reservoirs of infection of the disease, 24 r. muelleri and 17 r. sabanus were experimentally infected with the parasite. results show that although they can support the full development of the parasite, they are poor hosts. this confirms t ...19751145240
neodiplostomum (conodiplostomum) ramachandrani sp. n. from mueller's rat, rattus muelleri in malaysia.neodiplostomum (conodiplostomum) ramachandrani sp. n. is described from rattus muelleri in kepong, selangor, malaysia. it is characterised by having symmetrical dumbell-shaped testes, and vitellaria as a single ventral band in the hindbody. the taxonomic relations of neodiplostomum, conodiplostomum and fibricola are discussed and possible significance of the fluke as an ecological indicator noted.1976993573
establishment of a molecular tool for blood meal identification in malaysia.to establish a polymerase chain reaction (pcr) technique based on cytochrome b (cytb) gene of mitochondria dna (mtdna) for blood meal identification.201223569902
rodent species distribution and hantavirus seroprevalence in residential and forested areas of sarawak, malaysia.rodents belong to the order rodentia, which consists of three families in borneo (i.e., muridae, sciuridae and hystricidae). these include rats, mice, squirrels, and porcupines. they are widespread throughout the world and considered pests that harm humans and livestock. some rodent species are natural reservoirs of hantaviruses (family: bunyaviridae) that can cause zoonotic diseases in humans. although hantavirus seropositive human sera were reported in peninsular malaysia in the early 1980s, i ...201728228923
