RESUMO Existem diversas espécies de morcegos no Brasil, sendo somente três hematófagas. O morcego Desmodus rotundus (Geoffroy, 1810), conhecido como “morcego vampiro comum”, apresenta-se amplamente distribuído por todo território brasileiro e é encontrado em maior número do que as outras espécies de morcegos hematófagos. É responsável pela transmissão de diferentes doenças a outros mamíferos, especialmente a raiva nos herbívoros. Com o objetivo de avaliar regionalmente os ferimentos causados pelo D. rotundus em bovinos sob condições de campo, foram estudadas 12 propriedades rurais no período de março de 2005 a março de 2006 no Município de Valença, RJ. De um total de 580 bovinos examinados, foram observados 101 com ferimentos provocados por morcegos hematófagos (D. rotundus). Após análise dos resultados, pôde-se concluir que D. rotundus utiliza diferentes locais para se alimentar nos bovinos e as regiões corporais que apresentaram maior número de ferimentos foram a ântero e a póstero-superior. O elevado número de ferimentos encontrados, na metade superior dos bovinos (85,87%), justifica a adoção de metodologias de controle populacional de morcegos hematófagos que utilizem o contato corporal desses morcegos com o dorso do animal.

Background: Nowadays, rabbits and guinea pigs are frequently adopted as companion animals, representing a vehicle for the dissemination of potentially pathogenic and allergenic fungi to their tutors. This study aimed to characterize the cutaneous mycobiota of these species and evaluate the association between mycological cultures results and several variables related to these animals’ husbandry. Hair and scales samples (n=102) were collected from 32 rabbits and 19 guinea pigs: 51 by pulling hairs surrounding lesions and collecting scales (if lesions present) or along the body of the animal (if absent); the other 51 samples were collected using Mackenzie’s technique. Samples were inoculated in Sabouraud Chloramphenicol Agar and Dermatophyte Test Media and observed daily during the incubation period. Isolated fungal species were identified based on their macro and microscopic morphology. A questionnaire was provided to the animal’s tutors to collect information on animal husbandry.Results: Most frequently isolated species corresponded to saprophytic fungi, such as Aspergillus spp., Penicillium spp., Scopulariopsis spp.; Candida sp. and Rhodotorula sp. were also found. Statistical analysis showed that a positive mycological culture was related with animal’s age and the administration of ongoing medication, while the number of isolated fungal species was related with animal’s species and outdoor access.Conclusions: These fungi have already been reported as responsible for mycotic infections in humans and animals, including dogs and cats, although they usually affect immunocompromised individuals. Therefore, these animals can represent a zoonotic risk, which may be related with animals age, species, ongoing medication and outdoor access.

Statistical analysis showed that a positive mycological culture was related to animal’s age (p-value 0.00221) and the administration of ongoing medication (p-value 0.01532 for the variable anti-inflammatory drugs and 0,03680 for the variable antibiotics), while the number of isolated fungal species was related with animal’s species (p-value 0.00469 for the variable yard) and outdoor access (p-value 0.023260). These fungi have already been reported as responsible for mycotic infections in humans and animals, including dogs and cats, although they usually affect immunocompromised individuals. Therefore, these animals can represent a zoonotic risk, which may be related to animals age, species, ongoing medication, and outdoor access.
