Avaliação micológica em carcaça de suíno (Sus scrofa L.) para a determinação de intervalo post mortem

Abstract

This study aimed to identify the main fungal genera present in swine (Sus scrofa L.) tissues during the cadaveric experiment, leading to post-mortem interval (PMI) prediction using a forensic mycological approach. The study was conducted at the Instituto Federal do Piauí – Pedro II Campus, using two swine placed in different environments: one in the sun and the other in the shade. Samples were collected using sterile swabs from four anatomical regions: oral mucosa, skin, nostrils, and anus. The fungi were isolated and identified by culture in YG and CHROMagar medium, followed by microscopic analysis. Yeast species of the genus Candida were identified: C. tropicalis, C. glabrata, and C. krusei. The reported filamentous fungi were the genera Aspergillus sp., Chaetomium sp., Fusarium sp., Helminthosporium sp., Penicilium sp., Rhizopus sp., Scopulariopsis sp., and Trycophyton sp. It is concluded that forensic mycology, although still little explored, offers relevant data for estimating the postmortem interval and elucidating forensic cases, especially in contexts where entomology is not applicable. The study reinforces the importance of in-depth study of mycology applied to forensic science and highlights the need for further investigations using molecular biology techniques to increase the accuracy of fungal identification.
