Background and Objective: Bacterial diseases pose significant concerns in the poultry industry, profoundly affecting the health and productivity of these animals. These diseases can lead to decreased production levels and quality of meat and eggs, increased treatment costs, and a reduction in livestock products. Approximately 50% of mortality in chicks occurs due to bacterial infections within the first week of life; therefore, understanding and controlling these infections is crucial. This paper identifies and examines prevalent and important bacterial diseases in poultry, including significant diseases such as colibacillosis, salmonellosis, necrotic enteritis, mycoplasmosis, fowl cholera, and campylobacteriosis. The bacterial agents responsible for these diseases, their modes of transmission, clinical symptoms, and control and prevention methods will also be analyzed. The objective of this article is to provide comprehensive information to producers and researchers aimed at improving health management in the poultry industry and reducing the incidence of bacterial diseases.
Materials and methods: The search strategy in this study was as follows, using the terms bacterial diseases, poultry, colibacillosis, necrotic enteritis, Mycoplasma gallisepticum, pasteurellosis and also the English equivalent of these terms in Google Scholar. English and Farsi published articles related to this research were used to collect information.
Results: Findings: The present study shows that the mentioned diseases, including bacillosis, salmonellosis, necrotic enteritis, mycoplasmosis, fowl cholera and campylobacteriosis in poultry, are zoonosis and transmission to humans due to causing economic losses to the agriculture and animal husbandry industry. have a special.
Conclusion: Given the high importance of poultry health in food security, optimal control of these diseases can significantly enhance economic performance and public health within this sector.
