Resumo
Currently scholars question the action and effectiveness of antibiotics used in veterinary medicine and possible impacts on poultry. As regards the transmission of bacterial resistance to humans by the use of antibiotics in animal husbandry, although there is nothing proven. The frequency of emergence of new resistant phenotypes of various pathogens in human and veterinary medicine is a growing concern because infections caused by resistant bacteria are associated with greater morbidity and mortality than those caused by susceptible pathogens. The presence of antibiotics in animal feed generates a risk factor for human health and thus, is questioned the possible presence of residues in meat, milk or eggs, which can be in food additives themselves or their metabolites accumulated in products. Potential risks include hypersensitivity reactions to carcinogenic properties and induction of cross-resistance to pathogenic bacteria in humans. Thus, prolonged use of certain antibiotics can lead to selection of resistant bacteria within groups that are primary or opportunistic pathogens for humans. Although we discuss the practical relevance of these studies, there is a general consensus that a total ban on antibiotic growth promoters results in lower profitability for the sector. To which may have diets without the use of growth promoters, it is necessary to introduce new strategies to circumvent the negative effects on performance and health of the birds. Based on these data, the aim of a review on the use of antimicrobials, mechanism of action, and impact resistance in poultry.
