Bartonella infection Bartonella infection - Symptoms, diagnosis and treatment | BMJ Best Practice You'll need a subscription to access all of BMJ Best Practice Search  Bartonella infection Last reviewed: February 2019 Last updated: March 2018 Summary Infectious disease caused by various species of the bacterial genus Bartonella ; the three most important pathogens responsible for the majority of infections are B henselae , B quintana , and B bacilliformis . Some species are worldwide (...) in distribution ( B henselae ), whereas others are geographically localised ( B bacilliformis ). Bartonella species are transmitted from an infected natural host to the susceptible human host either by direct contact (cat bite or scratch for B henselae ) or via an insect vector (body lice for B quintana , sand fly for B bacilliformis ). Bartonella species infect erythrocytes and cause vascular proliferation, giving rise to prolonged fever, lymphadenopathy, and hepatosplenomegaly. Laboratory diagnosis

Bartonella henselae and Bartonella clarridgeiae infection, hematological changes and associated factors in domestic cats and dogs from an Atlantic rain forest area, Brazil. Cats are considered main reservoir of Bartonella henselae, which is transmitted to other cats especially through Ctenocephalides felis fleas, and to humans through scratching and biting. Serra da Tiririca State Park (PESET) is an Atlantic Forest area that shelters a wide variety of endemic fauna. Recently, the park has been (...) suffering due to irregular housing construction and domestic animal population that interacts with humans and wildlife. Given that surveillance policies for animals are part of the global Strategic Framework for One Health, the aim of this study was to detect Bartonella spp. DNA in cats and dogs, evaluating laboratory changes and associated factors. Blood samples of 124 dogs and 89 cats were collected for hematology and serum chemistry analysis. DNA was extracted and tested by conventional polymerase
