Relação entre Malassezia pachydermatis e cães sorologicamente positivos com leishmaniose visceral

Abstract

The objective of this work to investigate the association of Malassezia pachydermatis in dogs positive for Visceral Leishmaniasis. We used 80 mixed buds dogs, males and females of varying ages four months to eight years, previously selected after stool examination and serological ELISA-S7 for Visceral Leishmaniasis (CVL). After the results were studied two groups of 40 animals and 40 dogs positive to negative LVC. The animals were positive from the city of Caruaru mesoregion Agreste Pernambucano and Muribeca district in the city of Olinda, the negative group belonged to the Neighborhood of Cold Water in Recife. There were blood collection and cerumen ear canal, as well as friction in the groin by a sterile swab in all animals, areas chosen by election because they are moist and suitable for the proliferation of Malassezia. With the material obtained was carried out, respectively, ELISA for diagnosis of CVL and culture for the isolation of Malassezia. The analysis by sex of the animals studied, resulted in no statistically significant difference (p = 0.502), while males 23/40 (57.5%)more frequently than females 17/40 (42.5%). Animals positive for LVC, statistically significant for the presence of M. pachydermatis, where (p = 0,000). Among the findings showed that the clinical significance of M. pachydermatis in the group positive for LVC was media and itching, where the findings were, respectively, (p = 0.000) and (p = 0.042). The age of the animals, the adults were the most affected (between 2 and 7 years), occurring in 22 (55%), however, did not show statistical significance at (p =. 0.474). There was statistical significance the presence of M. pachydermatis swab the ear and groin between animals positive for LVC, being respectively (p = 0.000) and (p = 0.001). This study shows that M. pachydermatis can be present in pathogenic form in both healthy animals and in those that were positive for LVC, however, its occurrence in animals was significantly greater. In areas endemic for leishmaniasis, dogs that have ear infections, dermatitis and located in the belly of Malassezia, it is suggested that tests be performed for LVC.
