Objective. To describe the cases of infection with Bartonella henselae as presentation of fever of unknown origin (FUO) at the National Institute of Child Health (NICH) of Peru. Material and Methods. Study of a series of cases of children cared for in the NICH in 2012, infection was defined by B. henselae if presented positive serology. Results. In 2012, 26 cases were diagnosed of FUO of which 12 were due to infection by B. henselae, 06 were male, with a median age of 5 years (IQR 3,5-4,0), 11 of 12 had a history of exposure to cats, 6 of 12 had linear lesion caused by the cat. Within the lab tests 4 out of 12 had leukocytosis, 5 of 12 presented a CRP of greater than 10. The ultrasound examination revealed that 8 out of 12 lesions were hypoechoics in the spleen; there was co-infection with other infections; 02 cases had demonstration articulate and one with seizure. We conclude that the cases of FUO by infection by B. henselae in children are related to school-age, with the exposure of cats and injury hypoechoic in the spleen. Conclusions. We conclude that the cases of FUO by infection by B. henselae in children are related to the exposure of cats and injury hypoechoic in the spleen and liver and good prognosis.
