Serotypes of Pseudomonas aeruginosa isolated from laboratory rats and mice.
Pseudomonas aeruginosa isolates cultured from the feces of laboratory rats and mice were serotyped. The fecal samples originated from primary genetic centers, secondary breeding facilities, and research testing facilities operated under contracts from the National Cancer Institute. Eighty-nine percent or 264 of 297 isolates were of serotypes 1, 4, 6, 10, or 11, and of these, 154 (51.8%) isolates were serotypes 6 or 11. In some instances, Pseudomonas aeruginosa serotypes found in animals at a primary genetic center were also found at secondary breeding facilities which had received breeding stock from the primary genetic center. The same serotypes also were found in animals at research-testing laboratories that had received animals from the secondary breeding facilities.
