Abstract
Background
The fungi present in the decaying remains enable a better understanding of the processes of decomposition after death. There are not many studies about fungi on decaying bodies and it is not known which fungal sampling methods are effective.
Aims
The main objective of this study was to find the best method for sampling fungi in carcasses, prove the effectiveness of this method and identify the fungal colonies in animal carcasses from experimental burials.
Methods
Samples from 13 carcasses of Sus scrofa domestica, from the experimental project Taphos-m, were taken with different materials: spatula, sterile swabs and RODAC contact plates.
Results
RODAC contact plates with the RBA culture medium showed higher proliferation of fungal colonies. Thirty genera of fungi were isolated from different substrates (bone, tissue, lime). Most of the fungi genera or groups identified have been described before in the literature, but the substrates they came from were different in some cases.
Conclusions
Sampling with RODAC contact plates was found to be the most effective method, as it provides a nutritional culture medium that may allow growth since the moment of sampling. Fungi colonies grew better in RBA culture medium because bacterial growth is inhibited. Most of the observed fungi are related to the environment but some others have been found related to decomposing bodies for the first time.
期刊介绍：
Revista Iberoamericana de Micología (Ibero-American Journal of Mycology) is the official journal of the Asociación Española de Micología, Asociación Venezolana de Micología and Asociación Argentina de Micología (The Spanish, Venezuelan, and Argentinian Mycology Associations). The Journal gives priority to publishing articles on studies associated with fungi and their pathogenic action on humans and animals, as well as any scientific studies on any aspect of mycology. The Journal also publishes, in Spanish and in English, original articles, reviews, mycology forums, editorials, special articles, notes, and letters to the editor, that have previously gone through a scientific peer review process.
