The morphotaxonomy of Rhipicephalus microplus complex has been challenged in the last few years and prompted many biologists to adopt a DNA-based method for distinguishing members this group. In present study, we used mitochondrial DNA analysis characterise genetic assemblages, population structure dispersal pattern R. from Southeast Asia, region where species originated. A phylogeographic inferred 16S rRNA cytochrome oxidase subunit I (COI) genes was performed with five populations...
Amblyomma ticks parasitize a wide range of animals in tropical regions. This study describes the identification from wild snakes Malaysia and detection potential human pathogens such as Rickettsia, Anaplasma, Ehrlichia bartonellae ticks.Twenty one adult (twelve A. varanense nine helvolum ticks) identified seven Python molurus Sepang pool six Naja sumatrana snake Johore, were investigated this study. Amplification citrate synthase (gltA), 190-kDa surface antigen gene (ompA), 135-kDa (ompB)...
Limited information is available on the etiological agents of rickettsioses in southeast Asia. Herein, we report molecular investigation four patients attending a teaching hospital Malaysia. DNA Rickettsia sp. RF2125, typhi , and rickettsia closely related to raoultii was detected blood samples patients. Spotted fever group murine typhus should be considered diagnosis with nonspecific febrile illness this region.
Little data are available on the prevalence and transmission of vector-borne diseases in stray dogs Peninsular Malaysia. This study was designed to determine occurrence pathogens Malaysian using serological molecular approaches. In total, 48 dog blood samples were subjected analysis SNAP 4Dx kit (IDEXX Laboratories, Westbrook, ME). The presence Ehrlichia Anaplasma DNA Rhipicephalus sanguineus (Latreille) ticks detected nested polymerase chain reaction assays. Positive findings against canis...
Rickettsioses are emerging zoonotic diseases that often neglected in many countries Southeast Asia. Rickettsial agents transmitted to humans through exposure infected arthropods. Limited data available on the of indigenous community and animal farm workers aetiological arthropod vectors rickettsioses Peninsular Malaysia. Serological analysis Rickettsia conorii felis was performed for 102 individuals from at six rural villages 87 eight farms Malaysia a cross-sectional study. The had...
Little information is available on human anaplasmosis and ehrlichiosis in Southeast Asia despite increasing reports of the detection Anaplasma spp. Ehrlichia ticks. We report herein serological findings against tick-borne pathogens a group animal farm workers (n = 87) indigenous people 102) Peninsular Malaysia. IgG antibodies chaffeensis were detected from 29.9% 34.3% people, respectively, using commercial indirect immunofluorescence assays. Comparatively, only 6.9% but none seropositive to...
Farmworkers are at high-risk for tick bites, which potentially transmit various tick-borne diseases. Previous studies show that personal prevention against bites is key, and certain factors namely, knowledge, experience of health beliefs influence compliance with preventive behaviour. This study aimed to assess these their associations bite practices among Malaysian farmworkers.A total eight cattle, goat sheep farms in six states Peninsular Malaysia participated a cross-sectional survey...
