The aim of this study was to identify the aerobic bacteria of the auricular natural microbiota from healthy agoutis (Dasyprocta aguti Linnaeus, 1758). In the total, 48 agoutis were used in this experiment, being 32 adults and 16 puppies (both groups divided into equal parts between males and females). The animals were raised under captive conditions, in the Brazilian Semiarid. From each animal, a sample of auricular secretion was collected from each auricular pinna and processed for microbiological analyses. A total of 96 samples were collected and analyzed by colony macroscopic format, cytology and by biochemistry proofs with the objective of isolate and identify the microorganisms. The main bacteria found were Staphylococcus spp. (47.26%), Streptococcus spp. (12.80%), Bacillus spp. (22.73%) and Corynebacterium spp. (17.30%). As conclusion, the most frequent bacteria in auricular pinna of healthy agoutis are Gram-positive cocci and rods, similarly to found in some pets.
