[Detection of toxin-producing strains of Pasteurella multocida in nasal and tonsil swabs, a possibility for the control of atrophic rhinitis in swine breeding herds? Parallel comparison with other research methods].
Nasal, and partly tonsil swabs from pigs have been investigated by cell culture and ELISA respectively on toxigenic Pasteurella multocida strains. The controlled animals are from 89 non atrophic rhinitis- and 42 a.r.-positive herds. Toxin forming strains could not be isolated in non suspicious herds. 23 out of 42 infected herds showed toxigenic Pasteurellae. Despite a high increase in sample numbers, Pasteurella could not be detected in 19 infected herds (45%). When diagnosing atrophic rhinitis, we thus recommend to rely only on positive results of isolation. In all other cases, all other methods will have to be used in combination. Further research is necessary to find safe and fast test methods. According to recent experience, the blood-serological toxin screening test can be considered useful.
