Abstract

The authors, on the basis of scientific literature and their own diagnostic results, summarise important knowledge about intestinal spirochaetosis in different poultry species (turkeys, geese, ducks, domestic fowls), compared to swine dysentery. Causative role of spirochaetas in swine dysentery was confirmed in 1970s, and they were also detected in domestic fowl and turkey flocks from diseases with diarrhoea in countries of developed poultry farming (USA, Great Britain, Australia). In 1990s severe necrotic colitis with deaths in connection with spirochaetas was described in American ostrich (Rhea americana). From water fowl species, spirochaetas were detected from domestic duck flocks and wild ducks free of clinical signs, abroad, while later Hungarian authors reported first time, also internationally, spirochaetosis in geese with fibrinous-necrotic colitis and severe nephropathy. The authors carried out examinations in 28 Hungarian goose, 3 duck and 3 fowl flocks. Chronic diarrhoea with clinical signs occurred in broiler parent flocks at egg-laying period, with reoccurrence in spite of treatment. Mortality has not increased significantly, diarrhoea affecting 60% of flocks caused severe contamination of the litter, environment and eggs, later weakening of the animals, decrease in egg production and hatchability and leg paresis and necrosis of the skin of sole. In duck and goose flocks diseased in intestinal spirochaetosis - often at the end of egg-laying period - mortality gradually increased without visible signs of diarrhoea. Post mortem examination revealed fibrinous or necrotic inflammation of the caecum, colon and rectum, and chronic nephropathy often with fibrosis, and in the ducks arthritis of the tarsus and toes. The diagnosis was based on epidemiological data, clinical signs and pathological and pathohistological changes, demonstration of brachyspiras in the changed intestinal mucosa by silver impregnation or immunohistochemical method, culture on selective medium, and identification by biochemical tests and sequence analysis. In goose flocks Brachyspira alvinipulli was the most frequently detected. From fowl flocks 8, and from duck flocks 21 Brachyspira strains were isolated, from which Brachyspira hyodysenteriae (and in duck flocks B. pilosicoli, too) was dominant.
