Abstract

Several rodent-associated Bartonella species cause disease in humans but little is known about their epidemiology in Brazil. The presence of Bartonella spp. in wild rodents captured in two municipalities of the Mato Grosso do Sul state was assessed by polymerase chain reaction (PCR). Fragments of heart tissue from 42 wild rodents were tested using primers targeting the Bartonella 16S-23S intergenic transcribed spacer (ITS) region and citrate synthase gltA gene. The wild rodents were identified based on external and cranial morphology and confirmed at species level by mitochondrial DNA (cytochrome B) sequencing and karyotype. Overall, 42.9% (18/42) of the wild rodents were PCR positive for Bartonella spp.: Callomys callosus (04), Cerradomys maracajuensis (04), Hylaeamus megacephalus (01), Necromys lasiurus (06), Nectomys squamipes (01), Oecomys catherinae (01) and Oxymycterus delator (01). Bartonella vinsonii subsp. arupensis was detected in N. lasiurus (46%) and C. callosus (21%) captured in the two study sites. We reported the first molecular detection of B. vinsonii subsp. arupensis in different species of wild rodents collected in the Brazilian territory. Further studies are needed to examine the role of these mammals in the...Continue Reading

Bartonellosis

Bartonellosis is an infection caused by bacteria in the genus Bartonella and can present as a variety of diseases depending on the organism involved. While asymptomatic infection has been reported, immunocompromised individuals are more susceptible to severe infection. Find the latest research on bartonellosis here.

Cat-scratch disease

Cat-scratch disease, a relatively common infectious disease, is caused by Bartonella henselae and characterized by a fever and regional lymphadenitis. Here is the latest research.
