title: Species identification and serotyping (capsular antigen) of Pasteurella strains from sheep flocks in south Germany and in Syria.
abstract: 135 Pasteurella strains were cultivated from nasal swabs of sheep as well as pneumonic lungs of dead and slaughtered sheep. The specimen originated from 41 flocks in South Germany and from 15 flocks and 60 slaughter sheep in Syria (Hama region). Serovariety A2 prevailed amongst P. haemolytica strains (6) isolated in South Germany (53 strains) and in Syria (41 strains). In addition 10 further serovarieties were identified in South Germany (next frequent were A8, A1 and A6) and 7 in Syria. Untypable strains appeared to be more frequent in Syria. Other Pasteurellae (17) represented 1/4 of isolates in Syria and 1/3 of isolates in South Germany. Species identification resulted in P. multocida ssp. multocida (25), P. multocida ssp. septica (4 strains, Syria only), P. canis (3 strains, South Germany only) and Pasteurella-like strains (9 strains). Twelve P. multocida ssp. multocida strains carried capsular antigen D and 7 capsular antigen A. In most cases where multiple samples were examined from one flock, strains with different capsular antigens and/or belonging to different Pasteurella species were isolated (max. 8).
