RESUMO
Captive brown brocket deer (Mazama gouazoubira) were manually restrained to assess tear production by the Schirmer tear test I to measure intraocular pressure by applanation tonometry, to examine ocular conjunctival epithelial cells via cytologic and histologic samples, and to survey ocular conjunctival microflora by microbiologic culture. The mean value for the Schirmer tear test I was 8.9 +/- 1.8 mm/min, and the mean intraocular pressure was 15.3 +/- 3.1 mm Hg. Conjunctival epithelium contained stratified pavimentous layers of cells, and the microflora consisted of predominantly gram-positive bacteria.

Tuberculosis is a major public health concern, and diagnostic strategies applied to animal populations are scarce. As part of ongoing efforts to control tuberculosis dissemination at our animal facility, two non-human primates (NHP, Saimiri sciureus) presenting cutaneous lesions were examined for mycobacterial infection. Both animals tested positive for acid-fast bacilli and Mycobacterium tuberculosis using a molecular assay (IS6110 PCR). Animals were euthanized and several samples were tested for M. tuberculosis using the Xpert MTB/RIF assay. Many samples were positive for M. tuberculosis and rifampicin resistance, and some produced mycobacterial growth. Oral swabs from cage mates were then tested with Xpert MTB/RIF, and the majority tested positive for M. tuberculosis and rifampicin resistance, and produced growth in culture. To our knowledge, this is the first report of multidrug-resistant mycobacterial infection in NHP. Additionally, our data shows that the Xpert MTB/RIF assay can be useful as a screening tool for tuberculosis infection in NHP.
