CHARACTERISTICS OF PASTEURELLOSIS ASSOCIATED WITH CONTAGIOUS CLOACITIS IN CHICKEN
The article represents data of postmortem study of pasteurellosis associated with contagious (candidal) cloacitis in chicken. Clinical, epizootological, postmortem, bacteriological, and mycological analyses were performed for detection and assessment of etiological factors, prevalence, and course of cloacitis, as well as possible associated pathology. Highsex Brown chickens were examined, since this breed is mentioned to be predisposed to contagious cloacitis. It is found that the complex of diseases leads to change of clinical morphological symptoms, causes atypical course of the process, and impedes diagnosis. The main clinical signs of candidal cloacitis include sharp reduction in egg production and laying of eggs with blood-stained shell. The pathomorphological study revealed: catarrhal hemorrhagic or erosive ulcerous cloacitis, urethritis, nephrosonephritis, ovarian salpingitis. Pasteurellosis proceeded without typical pathologic changes and was characterized by development of catarrhal hemorrhagic duodenitis.
