Probióticos e simbiótico sobre o desempenho zootécnico e morfometria intestinal de frangos de corte desafiados com Salmonella Enteritidis

Abstract

In Brazil, in the last decades a of great concerns have been about the food poisoning, being that a of the most worrying comes to be related with the Salmonella. This disease stands out with great importance for its wide and varied occurrence in the man and animals; in which birds occupy the central point the epidemiology of Salmonella Enteric, representing a reservoir of great importance health and difficult to control. Salmonella Enteritidis is a pathogen belonging to the family intérico Enterobateriaceae, it comes to be among the more than 2,500 serotypes Salmonellas sp., one of the most common foodborne described in the literature. An prophylactic measures that is has been used to control the infection of the disease in poultry production, including antibiotics, selection of genetic strains of chickens to better immune response, development of the vaccine and use of probiotic products by inclusion competitive. The main concern with the continuous use of antibiotics, especially by various organizations worldwide is on the emergence and spread of pathogenic bacterial populations, bringing risks to both animal and human health. Seeking alternatives to ensure the production performance and food safety for consumers, we probiotcs foods supplements that are normally present in the gastrointestinal tract (ex.: Bacillus Subtilis e Bacillus Licheniformis), when they are administered correctly produce beneficial effects to the host, favoring the balance of their intestinal microbiota, may consist of microorganisms defined, undefined or synbiotics culture. However we do not have studies to prove which of the constitutions of probiotics is most effective in combating the Salmonella Enteric and in obtaining the best zootechinical performance, which requires larger studies regarding the different constitutions of probiotics available and ways of use. The aim of this study was approach by means of a bibliographic review the use of probiotics and synbiotics acting as auxiliary tool in combating intestinal Salmonella. A second goal is to develop a chapter with an article entitled: "Probiotics and synbiotic about zootechinical performance and intestinal morphometry of broilers challenged with Salmonella Enteritidis."
