Abstract: Bacterial infections remain one of the most significant causes of economic losses in poultry farming. Domestic waterfowl (ducks and geese), which have frequent contact with open water bodies and wild birds, may serve as reservoirs of pathogenic and opportunistic microorganisms. However, the bacterial profile of domestic waterfowl in the Kostanay Region has not previously been comprehensively studied. Between July 1, 2025, and July 1, 2026, a total of 267 samples were collected and examined at poultry farms in the Kostanay Region. The material included cloacal swabs and fecal samples collected from live chickens (n=32), ducks (n=85), and geese (n=29), as well as carcass surface swabs collected from dead birds of these species, together with surface swabs from chicken eggs (n=121). Samples were cultured on selective and differential diagnostic media, with final identification performed using MALDI-TOF MS. The most frequently isolated microorganism was Escherichia coli (79/267; 29.6%). The highest isolation rate was observed in samples from chickens (53.1%), followed by ducks (38.8%) and geese (37.9%). Klebsiella spp. (16.5%) and Campylobacter spp. (8.2%) were most frequently isolated from ducks, while Campylobacter spp. was also common in chickens (15.6%). Salmonella spp. was detected only in samples from chickens (0.37% overall), whereas S. aureus was detected in samples from geese and on the surface of chicken eggs (1.1% overall). Co-isolation of two microbial species was recorded in 4.9% of samples, predominantly those obtained from waterfowl. The broadest spectrum of the microorganisms studied-four of the five groups-was detected in samples from chickens and geese. The findings indicate the potential role of domestic waterfowl as reservoirs of Klebsiella spp. and Campylobacter spp. and support the need for a differentiated approach to veterinary and sanitary monitoring. Further research should include an expanded sample size, additional poultry species, including turkeys, and molecular genetic characterization of the isolated strains.
