| Abstract: | The pulmonary flora of 30 monkeys (Macaca fascicularis) was sampled by the transtracheal aspiration technique and the pharyngeal swab method, and the results were compared. The transtracheal aspiration technique yielded lower numbers of bacteria in both aerobic and anaerobic cultures. The bacteria isolated by transtracheal aspiration were predominately pure culture, thereby lowering the possibility of contamination from commensal flora. Bordetella bronchiseptica was isolated from 23.3% of the monkeys by transtracheal aspiration, but this organism was not isolated when samples were collected with pharyngeal swabs. |
