The poultry sector plays an important role in the Brazilian economy. With the
intensification of poultry production comes the need for tools to assist in the correct
detection of microrganisms responsible for production losses. Tocantins to own land
available and weather conditions such as heat and humidity that enhance the
production of this species, also favors the proliferation of pathogens, requiring early
diagnosis. Escherichia coli (E. coli) is a Gram-negative bacteria found in the normal
microflora of farm animals. However, there are pathogenic species which are
responsible for production losses in poultry due to problems such as sentences
during slaughter. Currently, these strains are separated into categories according to
their virulence factors responsible for the pathogenesis mechanisms, both animal
and human. The virulence factors ranging from the release of toxins to the presence
of specific genes which provide for the pathogenesis in the host. The correct
identification of each category of the bacteria through detecting the presence of
virulence factors with the aid of molecular biology plays a critical role in possible
decisions prophylaxis and improvement of handling, in order to minimize production
losses. Currently, there are few studies that identify intestinal extra injuries caused by
poultry E. coli diarrheagenic, so the aim of this study was to demonstrate the
association of diseases in poultry with pathotypes of E. coli commonly found in
mammals. |
