Resumen:
Objective: The present paper refers data about positive isolation and Histoplasma capsulatum characterization in captured infected bats from the states of Guerrero, Morelos, and Oaxaca: Pteronotus parnellii; P. davyi; Myotis californicus; Mormoops megalophylla; Natalus stramineus; Artibeus hirsutus; Leptonycteris nivalis; and L. curasoae. Data of fungal isolation from infected bats: New records of bat H. capsulatum infection are registered in the State of Oaxaca for P. parnellii, P. davyi, and L. curasoae; this is the first report in the world for the last two species. Data suggest a high risk of bat infection in those specimens living in caves with the following conditions: low ceilings, irregular topography, and abundant guano deposits. Genetic polymorphism of H. capsulatum isolated from infected bats: The polymorphic DNA patterns of the fungus isolated from twelve infected bats, captured in Guerrero and Morelos, were analyzed by a high sensitive new polimerase chain reaction (PCR)-based method of DNA fingerprints, called the random amplified polymorphic DNA (RAPD). Two different polymorphic DNA patterns of H. capsulatum isolated from bats were found, which could represent the fungal molecular markers for the geographic areas studied, and could be associated to bat movements in these areas. Conclusions: The role of bats as reservoirs and responsible of H. capsulatum spreading in nature is suggested related, to their use of permanent harborages (caves), their alimentary habits, and their movements and migration.
