Infection by fungi of the genus\n                    <jats:italic>Paracoccidioides<\/jats:italic>\n                    has been reported in several animal species but has not yet been described in reptiles.

Serum samples from 50 free-ranging caimans were analyzed by ELISA and immunodiffusion using gp43 and exoantigen, respectively. Anti-gp43 antibodies were detected in 30% of the samples by ELISA, whereas no reactivity was observed by immunodiffusion. No significant differences were found between males and females, indicating similar exposure to the pathogen.
