Caracterização anatomopatológica e bacteriológica em frangos de corte condenados totalmente por colibacilose sob Serviço de Inspeção Federal

Abstract: RESUMO: A colibacilose é a principal causa infecciosa de condenação total de carcaça em frangos de corte no sul do Brasil. Esse trabalho tem por objetivo determinar o grau de concordância entre a condenação total por colibacilose de frangos de corte abatidos em estabelecimento sob Serviço de Inspeção Federal (SIF) com o diagnóstico anatomopatológico e bacteriológico. O estudo foi realizado com 45 frangos de corte condenados totalmente por colibacilose (caso) e seus respectivos 45 controles (frangos sem lesões)… Show more

“…The association of different predisposing factors may result in distinct clinical pictures (Barnes et al 2008, Abalaka et al 2017), during the period in which the birds died (summer), the southern region of Mozambique registered high temperatures, varying from 36 to 42°C (INAM 2018). Environmental factors, such as extreme heat, high humidity and poor ventilation, constitutes major challenges in poultry industry world widely, both for industrial and subsistence systems, since it increases bird's susceptibility to diseases, especially with an infectious origin, such as colibacillosis (Chansiripornchai 2009, Casagrande et al 2017. Escherichia coli is an avian commensal agent of the intestinal tract (Barnes et al 2008, Srinivasan et al 2014, Guabiraba & Schouler 2015, and, despite several predisposing factors were identified (high temperatures, prolonged fasting, poor ventilation), (Giovanardi et al 2005, Barnes et al 2008.…”

“…The presence of coinfections favors disease occurrence and determines the severity of the colibacillosis (Hossain et al 2015, Casagrande et al 2017, Kim et al 2020. In Mozambique, despite vaccination efforts against the main viral conditions in poultry reports of Newcastle disease, Influenza infection, infectious bronchitis, pasteurellosis and salmonellosis outbreaks are frequent (FAO 2013).…”

“…Colibacillosis, a disease caused by E. coli, present in the gastrointestinal tract of broilers, can cross the intestinal barrier and reach other organs, beginning an respiratory infection, and can also cause septicemia with colonization of internal organs (Casagrande et al, 2017).…”

“…No Brasil, estudos têm correlacionado as lesões macroscópicas de causa infeciosas e a caracterização histológica com o isolamento do agente presente nos órgãos afetados. Tais pesquisas têm fundamental importância para avaliação do impacto dos agentes infecciosos como causa de condenação da produção em abatedouros de frango de corte 20 .…”
