RESUMO
The collared anteater ( Tamandua tetradactyla ) is adapted to a variety of habitats. It is a solitary species for which no reference values for ophthalmic tests have been established. Eight animals ranging from 1 to 4 yr of age, two males and six females, were manually restrained for assessment. Ophthalmic tests included evaluation of tear production by Schirmer tear test 1 (STT1), endodontic absorbent paper point tear test (EAPPTT), palpebral fissure length (PFL), culture of the conjunctival bacterial flora, and antimicrobial susceptibility test. Median ± semi-interquartile range (S-IQR) STT1, EAPPTT, and PFL were 8.50 ± 4.13 mm/min, 14.13 ± 3.24 mm/min, and 15.91 ± 2.51 mm, respectively. Bacterial growth was present in 100% of the samples, with predominance of Gram-positive bacteria (70.27%). Staphylococcus spp. was the most frequently isolated genus. Antimicrobial susceptibility test showed sensitivity of Staphylococcus epidermidis and Staphylococcus spp. to neomycin, tobramycin, and gentamicin. The results in this study can benefit the determination of reference values for different diagnostic techniques, and may be used as a guide for diagnosis and treatment of ocular diseases in collared anteaters.
