Blazes DL, Mullins K, Smoak BL, Jiang J, Canal E, Solorzano N, Hall E, Meza R, Maguina C, Myers T, Richards AL, Laughlin L - Emerging Infect. Dis. (2013)

Bottom Line: While studying chronic verruga peruana infections in Peru from 2003, we isolated a novel Bartonella agent, which we propose be named Candidatus Bartonella ancashi.This case reveals the inherent weakness of relying solely on clinical syndromes for diagnosis and underscores the need for a new diagnostic paradigm in developing settings.

Figure 1: Clinical presentation of verruga peruana in 3-year-old boy, Peru, 2003.

Mentions: The patient was a 3-year-old boy with no known underlying medical history who was identified in 2003 as having clinical verruga peruana by the classic appearance of the eruptive nodular rash (Figure 1). He and his family lived in a rural setting near the town of Caraz, Ancash region, Peru. He lived in close proximity to numerous pets and farm animals and had experienced insect bites around the time the eruptive rash developed. His rash had been present for ≈30 days, and he had no fevers, chills, or arthralgias. Baseline laboratory studies included complete blood counts and bacterial culture for Bartonella species, using methods previously described (5,6). Briefly, the media was biphasic, consisting of Bacto agar with Proteose Peptone No. 3 (Becton, Dickinson and Co., Sparks, MD, USA), dextrose, sodium chloride and 10% defibrinated sheep’s blood, and RPMI supplemented with 10% inactivated fetal bovine serum.
