Abstract

Coccidioidal pericarditis is a condition found in approximately 1–5 % of patients infected by species. It is associated with widely diverse clinical symptoms. This paper reports a case of coccidioidal pericarditis diagnosed by an in-house antigen and confirmed with mycological and molecular methods. From February to September 2005, the patient suffered from fever, weight loss, a non-productive cough, thoracic pain and tachycardia. He received a positive diagnosis of coccidioidal pericarditis only in October 2005. The macromorphological examination of the culture showed a whitish felt-like colony, which became brownish with age. Preparations in lactophenol cotton blue stain showed hyaline septate hyphae with fragmentation and thin arthroconidia-like structures. Pericardial fluid and sera samples were positive for antibodies by immunodiffusion and ELISA with a in-house antigen preparation. The identification was confirmed by nested PCR of the antigen 2/proline-rich antigen (Ag2/PRA) encoding gene.
