Abstract

We documented extreme alopecia in a maternal colony of Rafinesque's big-eared bats (Corynorhinus rafinesquii) roosting beneath a concrete bridge in west-central Mississippi in the spring of 2000. Approximately half of the colony lacked hair dorsally and ventrally in the chest, shoulder, and neck regions. We again observed partially hairless bats during 2004 and 2011 surveys. Dermatophyte cultures on skin and hair samples were positive on specimens examined in 2004, but fungi identified were nonpathogenic. Environmental stress is implicated as a potential factor contributing to alopecia in the population.

En la primavera del año 2000, se documentó alopecia extrema en una colonia maternal del Murciélago orejón de Rafinesque (Corynorhinus rafinesquii) perchada bajo un puente de concreto en el área oeste-central de Mississippi. Aproximadamente la mitad de la colonia carecía cabello en las áreas dorsales y ventrales del pecho, cuello y de los hombros. Murciélagos parcialmente calvos fueron observados también durante los monitoreos de 2004 y 2011. Culturas de dermatofitos dieron positivas en muestras de la piel y del pelo tomadas en el muestreo del 2004, pero los hongos identificados no fueron patógenos. Estrés ambiental es considerado como un factor potencial que ha causado alopecia en la población.
