Abstract
The fungus Histoplasma capsulatum is the causative agent of histoplasmosis, disease of public health importance. The aim of this study was to determine its presence in faeces of domestic pigeons (Columba livia) in the city of Lima, Peru. Faecal samples (n=245) were collected, processed and cultivated in Sabouraud agar at 37 and 28 °C for 2 to 4 weeks approximately. The colonies were identified by macroscopic and microscopic characteristics. Only 0.41% (1/245) of samples were positive to H. capsulatum, while the beta-pert (@Risk) stochastic simulation showed a minimum prevalence of 0.369% and a maximum prevalence of 0.451%.

Funding Information:Distribución de la prevalencia del hongoHistoplasmacapsulatum por distribución estocástica beta-pert (@Risk) en muestras de heces de palomas de Castilla y palo-mas mensajeras (n=245) en la ciudad de Lima, Perú (2015) morfológicas se realizaron pruebas adiciona-les (tinta china, prueba de urea) para identifi-car la especie. Cuando la colonia presentó crecimiento tipo moho, se hizo una impronta con cinta adhesiva sobre una lámina portaobjetos que contenía una gota de lactofenol, y se observó en el microscopio a 40X y a 100X para observar la presencia de un conidióforo que permita identificar la es-pecie.
