O grande impacto do Clostridium perfringens na avicultura

Abstract

Clostridium perfringens type A is a Gram-positive anaerobic bacterium that inhabits the intestinal native biota of the intestine of birds. The objective of this review is to analyze different factors that predispose their pathogenicity and bacterial growth, leading to necrotic enteritis, a enterotoxemic disease characterized by hemorrhagic necrosis of the intestinal mucosa, affecting mainly broilers between 4 to 8 weeks of age or older, especially in poultry farms intensified, being a problem for morbidity and mortality hurting performance, weight, food, and due to its presence along the production of broilers, conversion it can be transmitted to humans through the consumption of contaminated poultry products. Its importance in the poultry field has led us to investigate alternatives to prevent and control the disease produced by Clostridium perfringens in poultry, and also reduce the proliferation and economic losses.

Clostridium perfringens as Foodborne Pathogen in Broiler Production: Pathophysiology and Potential Strategies for Controlling Necrotic Enteritis

“…For example, in broilers the toxin causes necrotic enteritis, which could lead economic losses. The role of the necrotic enteritis B-like toxin (NetB) present in G strains causes NE, which is more frequent in chickens fed wheat or barley-based diets than in those fed with corn [ 34 , 35 ], due to the difference in clostridia proliferation in the diets resulting in a higher number of bacteria in the intestine, as well as a lack of fluidity and digestion, generating an increase in the incidence of NE in chickens and increasing the viscosity of the intestinal contents, mucus production, and growing bacteria [ 35 , 36 ].…”
