Identification of diverse Bartonella genotypes among small mammals from Democratic Republic of Congo and Tanzania.
Gundi VA , Kosoy MY , Makundi RH , Laudisoit A . Am J Trop Med Hyg 2012 87 (2) 319-26 Small mammals from the Democratic Republic (DR) of the Congo and Tanzania were tested to determine the prevalence and genetic diversity of Bartonella species. The presence of Bartonella DNA was assessed in spleen samples of the animals by rpoB- and gltA-polymerase chain reactions (PCRs). By rpoB-PCR, Bartonella was detected in 8 of 59 animals of DR Congo and in 16 of 39 Tanzanian animals. By gltA-PCR, Bartonella was detected in 5 and 15 animals of DR Congo and Tanzania, respectively. The gene sequences from Arvicanthis neumanni were closely related to Bartonella elizabethae. The genotypes from Lophuromys spp. and from Praomys delectorum were close to Bartonella tribocorum. Five genogroups were not genetically related to any known Bartonella species. These results suggest the need to conduct further studies to establish the zoonotic risks linked with those Bartonella species and, in particular, to verify whether these agents might be responsible for human cases of febrile illness of unknown etiology in Africa. |
Molecular detection and identification of Bartonella species in Xenopsylla cheopis fleas (Siphonaptera: Pulicidae) collected from Rattus norvegicus rats in Los Angeles, California.
Billeter SA , Gundi VA , Rood MP , Kosoy MY . Appl Environ Microbiol 2011 77 (21) 7850-2 Of 200 individual Xenopsylla cheopis fleas removed from Rattus norvegicus trapped in downtown Los Angeles, California, 190 (95%) were positive for the presence of Bartonella DNA. Ninety-one amplicons were sequenced: B. rochalimae-like DNA was detected in 66 examined fleas and B. tribocorum-like DNA was identified in 25 fleas. The data obtained from this study demonstrates an extremely high prevalence of Bartonella DNA in rat-associated fleas. |
Prevalence and genetic diversity of Bartonella detected in different tissues of small mammals of Nepal
Gundi VA , Kosoy MY , Myint KS , Shrestha SK , Shrestha MP , Pavlin JA , Gibbons RV . Appl Environ Microbiol 2010 76 (24) 8247-54 Bartonellae were detected in a total of 152 out of 642 (23.7%) tissues from 108/223 (48.4%) small mammals trapped in several urban areas of Nepal. Based on rpoB- and gltA-sequence analysis, genotypes belonging to seven known Bartonella species and five genotypes not belonging to previously known species were identified in these animals. |
