[The occurrence of Escherichia coli, Aeromonas hydrophila, Plesiomonas shigelloides and Clostridium perfringens in the intestinal flora of gray herons (Ardea cinerea)].
The flora of the large intestine of 92 grey herons was examined for the frequency of aerobic and microaerobic growing bacteria. Clostridium perfringens, Aeromonas hydrophila, Plesiomonas shigelloides and E. coli were isolated from 55%, 48%, 14% and 35% of the birds, respectively. It could be demonstrated that the findings of these bacteria in the intestinal flora are depending on the age of the birds. The percentage of carriers of Clostridium perfringens, Aeromonas hydrophila and Plesiomonas shigelloides was highest in nestlings younger than 18 days, less high in older nestlings and lowest in adult grey herons. Contrary to those bacteria, E. coli was found more often in the intestinal flora at increasing age of the birds. Salmonella spp. were isolated from 6 birds. Two birds yielded positive for Yersinia enterocolitica and Campylobacter spp., respectively. Other aerobic and microaerobic bacteria play a less significant role as part of the intestinal flora.
