Fowl cholera

摘要

Fowl cholera is a septicemic disease caused by Pasteurellamultocida which affects a variety of domesticated and wild birds. This highly contagious disease causes high morbidity and mortality resulting in great economic losses, especially in large industrial-type poultry complexes. It usually occurs as an acute disease, but chronic infections can also occur in some outbreaks. Pasteurellamultocida type A is the etiologic agent of fowl cholera, highly contagious and fatal disease of chickens. Pasteurellamultocida have five types of capsular serotype i.e. type A, B, D, E and F. Diagnosis of the disease is mainly based on the clinical signs and symptoms, post mortem findings. Confirmatory diagnosis is done by isolation and identification of causative agent. A variety of laboratory diagnostic techniques have been developed over the years for pasteurellosis and used routinely in the laboratory. Among these techniques molecular techniques of diagnosis is most important. Accurate and early diagnoses are considered as the effective tools to frame the strategy for controlling of any infectious disease like Fowl cholera. Vaccination is considered as one of the common preventive measures worldwide to reduce the prevalence and incidence of disease. Control of fowl cholera is primarily ensured by good management practices and treatment with antimicrobial agents.
