Recent studies have shown that filamentous and yeast fungi have been found dispersed in the air and on subway surfaces. 2 Some of these fungi can be considered as causing damage to humans and are responsible for triggering allergic processes, intoxications and infections. The fungus genera most found in studies that analyzed contamination in environments where: Cladosporium sp, Penicillium sp, Aspergillus sp, Mucor sp, Rhizopus sp, Candida sp, Alternaria sp, among others. 2,4 In view of the above, the objective of this study was to evaluate the contamination caused by fungi in subways of the metropolitan region of Recife-PE. Methods Sample collection and processing This is an experimental, descriptive research with a quantitative approach, carried out in the subways of the metropolitan region of Recife-PE, in the South (Cajueiro seco), Camaragibe and Jaboatao lines, to evaluate the occurrence of fungus contamination in the various surfaces of the subway also the fungal identification.
