Abstract
FUNES, Guillermo; MATA-DELGADO, Cristian; JAIKEL-VIQUEZ, Daniela and GUERRERO-MENDOZA, Zoila Virginia. Isolation of Cryptococcus neoformans from droppings of the Feral Pigeon (Columba livia) found in public places in El Salvador. Acta méd. costarric [online]. 2022, vol.64, n.1, pp.52-57. ISSN 0001-6002. http://dx.doi.org/10.51481/amc.v64i1.1227.
Aim:
The objective of this study was to isolate yeast that belonged to the Cryptococcus neoformans species complex from the feces of the Feral Pigeon (Columba livia), from public places in El Salvador. Methods: Samples were seeded in conventional culture media and confirmed colonies were typed using the enzyme restriction technique of the URA5 gene.
Results:
Of a total of 66 samples analyzed, three were positive for yeasts that belonged to the Cryptococcus neoformans species complex. The molecular study grouped the isolates in the molecular types VNI and VNII; both belonging to the species Cryptococcus neoformans sensu stricto. Conclusions: In the studied sites the presence of this yeast is very low, probably due to environmental factors. We present the first report of Cryptococcus neoformans sensu stricto genotypes VNI and VNII in El Salvador. This specie is relevant in public health for being responsible for more than 90% of cases of cryptococcosis worldwide.
