Microbial contamination in the indoor environment of tanneries in Leon, Mexico

This study has illustrated the presence of pathogens, hazardous to humans in indoor environments of tanneries. The identified bacteria by sequencing of 16S rDNA gene, belonged to families: Bacillaceae, Corynebacteriaceae, Enterobacteriaceae, Moraxellaceae, Nocardiopsaceae, Pseudomonadaceae, Staphylococcaceae. Some of which can be categorized as pathogens such as Acinetobacter calcoaceticus, Acinetobacter johnsonii, Nocardiopsis dassonvillei, Pantoea agglomerans, Pseudomonas putida and Staphylococcus gallinarum. In addition, Fungi genuses identified by microscopy were Aspergillus and Penicillium. The yeasts presumptively identified by ChromAgar medium were Candida krusei and Candida glabrata. Some of these identified microorganisms have been correlated with adverse human health effects, especially in individuals with immunocompromised system.
