Resumo: | Litopenaeus vannamei, which is the most common shrimp species cultivated in the northeast of Brazil, is very susceptible to microbial diseases, and this consequently affects productivity. There are reports of bacteria, viruses and protozoa in these shrimp, but not fungi. This study aims to isolate and identify fungi present in shrimp Litopenaeus vannamei, and in their nursery waters, at two breeding farms in Brazil. The pathogenic potential of the isolates was assessed through the qualitative detection of proteases and aflatoxin B production. The 146 isolated fungi comprised 46 species. Aspergillus, Penicillium and Furarium were the three most relevant genera and Aspergillus flavus was the predominant species with a total of 33 isolates. Most of the isolated species are known as potentially pathogenic to humans and other animals. Eighteen isolates of A. flavus and two of A. parasiticus were able to produce aflatoxin B and 33 out of the 46 species produced protease, indicating that these fungi may also become pathogenic to shrimp and their consumers.
