Isolamento De Enterobactérias a Partir De Frangos De Corte Necropsiados: Relato De Caso

Abstract

The pathogenic bacterium Escherichia coli(E. coli) causehealth problems to production animals, i.e.avian colibacillosis. This disease presents multifactorial causes,manifestingchronic respiratory disease, omphalitis, salpingitis, septicemia, peritonitis, swollen head syndrome, enteritis,and cellulitis. Thepresent study aimed to report clinical findings of three birds from a breeder at Primavera do Leste,MT, Brazil, necropsied to the anatomopathological analysis and isolation of the causative agents. The analysis identified hepatic necrosis, presence of catarrhal secretion to the medial portion of trachea, and cellulitis with evolution to abscess. Microbiological tests resulted to the isolation of lactose-fermentiveGram-negative bacteria, characterizedasenterobacteria, i.e.E. coli.

Relationship Between Pre-Slaughter Factors and Major Causes of Carcass Condemnation in a Broiler Slaughterhouse under Federal Inspection

“…Broiler age was correlated positively with cachexia and negatively with ascites, indicating that older age may increase condemnation for cachexia and decrease that for ascites. According to Duarte & Santana (2019), older animals are more susceptible to certain diseases and infections, which might be associated with condemnation for cachexia, given that the condition is caused by diseases such as colibacillosis (Duarte & Santana, 2019) and Marek's disease (Tambiev et al, 2021). The decrease in condemnation for ascites with increasing age (p<0.05) might be due to the fact that ascites occurs mainly in birds aged 8 to 21 days.…”
