Abstract:
Listeria spp. were isolated from faeces samples from 12 (3.4%) of 350 pigeons examined. Three isolates were identified as L. monocytogenes (1x serovar 1/2a, 1/2b, and 4ab), eight isolates were L. innocua (2x serovar 6a, 6x serovar 6b), and two isolates L. seeligeri (serovar 6b). One fecal sample yielded a mixed culture of L. monocytogenes and L. innocua. The results indicate that pigeons are not important in the epidemiology of listeriosis in man and animals.
Insights
Pigeons shed Listeria species, including Listeria monocytogenes, in their feces. However, these findings suggest pigeons play a minimal role in the spread of listeriosis among humans and animals.
