25 and 17 Salmonella strains could be isolated from 429 and 423 blackheaded gulls (Larus ridibundus), respectively, during two years of examination. S. typhimurium was the most frequent serovar. All strains of S. typhimurium belonged to the biochemovar c (inosite and rhamnose negative), nearly a third of isolates caused a mannose-sensitive hemagglutination of guinea pig erythrocytes. This result is in contradiction to the literature. Furthermore the phagovars, the plasmid profiles and the resistance against chemotherapeutics were tested. The Salmonella carriage by gulls presumably reflects the contamination of the environment.
