CACERES, Abraham G et al. Detection of Bartonella spp. and Rickettsia spp. in fleas, ticks and lice collected in rural areas of Peru. Rev. peru biol. [online]. 2013, vol.20, n.2, pp.165-169. ISSN 1727-9933.

Bartonellosis and rickettsiosis are commonly reported in Peru. In order to detect Bartonella sp. and Rickettsia sp. in fleas, ticks and lice, specimens from five distinct locations in Peru (Marizagua, Cajaruro, Jamalca, Lonya Grande and El Milagro) were collected and screened for the presence of these bacteria using PCR and later confirmation by DNA sequencing. The specimens collected were distributed in 102 pools (76 Ctenocephalides felis, 2 Ctenocephalides canis, 16Pulex irritans, 5 Pediculus humanus, 2 Rhiphicephalus sanguineus, and 1 Boophilus spp.), whereBartonella was detected in 17 pools (6 of C. felis, 9 of P. irritans, 1 of C. canis, and 1 P. humanus). Also, Rickettsia was detected in 76 pools (62 C. felis, 10 P. irritans, 2 P. humanus, and 2 C. canis). Bartonella clarridgeiae was detected in C. felis, C. canis and P. irritans pools at 5.3%, 50% and 12.5%, respectively. Bartonella rochalimae was detected in one C. felis and two P. irritans pools at 1.3% and 12.5%, respectively. Furthermore, B. henselae was detected in one C. felis pool and one P. humanus pool corresponding to 1.3% and 20%, respectively; andBartonella spp. was also found in 5 pools of P. irritans at 31.3%. Additionally, R. felis was detected in C. felis, C. canis and P. irritans pools at 76.3%, 100% and 37.5%, respectively; and Rickettsia spp. was detected in C. felis, P. irritans and P. humanus pools at 5.3%, 25% and 40%, respectively. These results demonstrate the circulation of these bacteria in Peru
