Mycoses in red snapper (Lutjanus campechanus) caused by two deuteromycete fungi (Penicillium corylophilum and Cladosporium sphaerospermum)

We report two species of deuteromycete fungi (Penicillium corylophilum and Cladosporium sphaerospermum) concurrently infecting the swim bladder and posterior kidney and causing erratic behavior in two specimens of wild-caught, tank-held red snapper (Lutjanus campechanus). Lesions produced by both sp...

Description
Summary:We report two species of deuteromycete fungi (Penicillium corylophilum and Cladosporium sphaerospermum) concurrently infecting the swim bladder and posterior kidney and causing erratic behavior in two specimens of wild-caught, tank-held red snapper (Lutjanus campechanus). Lesions produced by both species infiltrated the immediately surrounding tissue and produced severe pathological changes; however, the infection apparently was not systemic. Only P. corylophilum grew in the initial culture from the swim bladder and only C. sphaerospermum grew in the initial culture from the kidney. Infection may have occurred upon penetration of a syringe to deflate the swim bladder. There was no horizontal transmission to 13 other specimens of red snapper held in the same tank. This suggests that these fungi are not primary pathogens. Injection of each species into various sites in the Gulf killifish, Fundulus grandis, failed to produce infections within 1 month, suggesting differences in susceptibility among species.[PUBLICATION ABSTRACT]
