We also tested 83 blood spots collected on Flinders Technology Associates (FTA) cards from guinea pigs inhabiting 338 Peruvian households. <jats:italic>Bartonella<\/jats:italic> DNA was detected in 81 (20.7%) of 391 guinea pig fleas, in five (2.6%) of 194 human fleas, and in 16 (19.3%) of 83 guinea pig blood spots. Among identified <jats:italic>Bartonella<\/jats:italic> species, <jats:italic>B. rochalimae<\/jats:italic> was the most prevalent in fleas (89.5%) and the only species found in the blood spots from guinea pigs. Other <jats:italic>Bartonella<\/jats:italic> species detected in fleas included <jats:italic>B. henselae<\/jats:italic> (3.5%), <jats:italic>B. clarridgeiae<\/jats:italic> (2.3%), and an undescribed <jats:italic>Bartonella<\/jats:italic> species (4.7%).
