Item Abundance and distribution of Xenopsylla cheopis on small mammals collected in West Java, Indonesia during rodent-borne disease surveys.(2006-09-06) Ibrahim, Ima Nurisa; Winoto, Imelda; Wongsrichanalai, Chansuda; Blair, Patrick; Stoops, CraigDuring February 2004 and September 2005, Xenopsylla cheopis were collected from small mammal hosts during rodent-bone disease surveys in Jakarta and Bandung, Indonesia. During 4 trap nights in Jakarta, 4 rodent species (Rattus exulans, Rattus norvegicus, Rattus tanezumi and Mus musculus) and one shrew species (Suncus murinus) were collected. Rattus tanezumi had the highest X. cheopis load (128 X. cheopis from 84 R. tanezumi) but R. norvegicus had the highest flea index, 1.8. In Bandung, over 6 trap nights 3 rodent species were collected (R. norvegicus, R. tanezumi and M. musculus) and the shrew, S. murinus, were collected. Rattus norvegicus had the highest number of X. cheopis collected (407 X. cheopis from 181 R. norvegicus) but R. tanezumi had the highest flea index, 3.5. During both surveys, X. cheopis was the species of flea collected.Item Bartonella species in rodents and shrews in the greater Jakarta area.(2005-11-14) Winoto, Imelda L; Goethert, Heidi; Ibrahim, Ima Nurisa; Yuniherlina, Ikke; Stoops, Craig; Susanti, Ika; Kania, Winny; Maguire, Jason D; Bangs, Michael J; Telford, Sam R; Wongsrichanalai, ChansudaIn February 2004, we captured 221 rodents and shrews in the Greater Jakarta area as part of a study to determine the prevalence of rodent-associated vector-borne infections. Microscopic examination of blood smears revealed 6% (13/218) to be positive for Bartonella spp. The corresponding DNA samples, either from blood blots or frozen spleen pieces and from fleas collected on these animals, were tested for evidence of Bartonella infection by PCR, targeting the portions: 378bp and 930bp of the citrate synthase gene (g/tA). The sequences from our sample clusters with a Peruvian entity, B. phoceensis, B. rattimassiliensis and B. elizabethae, the latter species has been associated with endocarditis and neuroretinitis in humans. As previous analyses have shown, there appears to be little geographic or host consistency with phylogenetic placement. The public health significance of these findings remains to be determined.
