摘要

To the Editor: Human mono-cytic ehrlichiosis is a tick-borne in-fectious disease caused by Ehrlichia chaffeensis (1). Serologic studies have indicated E. chaffeensis infection in Latin American countries: Venezuela (2), Mexico (3), Argentina (4), Chile (5), and Brazil (6). However, no mo-lecular evidence for E. chaffeensis has been reported.In December 2001, a 9-year-old boy was admitted to a hospital in Carabobo, Venezuela, after 3 days of fever (39°C–41°C), malaise, an-orexia, headache, abdominal pain, and cutaneous tick-bite lesions. Dur-ing the 6 weeks before admission, the patient had been exposed to ticks in a rural area (Cojedes, Venezuela). At the time of physical examination, the patient appeared acutely ill with fe-ver (41°C), dehydration, somnolence, conjunctivitis, facial edema, cervical adenomegaly, soft depressible abdo-men painful to palpation, and hepa-tomegaly. Cardiopulmonary exami-nation found regular cardiac sounds with systolic tricuspid murmur and abnormal bilateral respiratory sounds (rhonchi). Skin examination showed multiple tick bites and an erythema-tous maculopapular rash. Appropriate informed consent was obtained
