Etiopatogenia da salmonelose em bezerros: revisão de literatura

Abstract

Bacteria of the Salmonella genus belong to the Enterobacteriaceae family and have a zoonotic character, that is, the ability to infect humans and animals. the salmonellosis in calves can generate a series of damages to the producer, determined both by the fall in production and by mortality, since the course of the disease can occur quickly. The gateway for infection is the oral cavity, where even the ingestion of a small amount of the bacteria found in water or food is already capable of triggering the disease in a healthy animal. The main clinical signs are characterized by watery diarrhea, brown in color, which may present with fragments of mucosa, fibrin, streaks of blood and a foul odor, in addition to high fever, pneumonia, polyarthritis and gangrene of the extremities. The prognosis is reserved to good, as measures and practices adopted for prevention or immediate methods. This work aims to review the literature on the main characteristics of the pathogenesis of salmonellosis in calves, as well as the clinical manifestations that may be presented as the disease progresses.
