Resistance of Salmonella spp. isolated from poultry meat to antimicrobial drugs

Abstract

Uncontrolled use of antimicrobials in the prophylaxis and treatment of human and animal diseases leads to the appearance of residues in the environment and food. The use of antimicrobials as growth promoters in breeding affirms the importance of their residual finding in foods of animal origin. Bacteria of the genus Salmonella are one of the most common causes of food poisoning. All species of this genus are pathogenic to humans and cause various diseases known as salmonellosis. Humans can become infected through the faecal-oral route by consuming contaminated food and water or by direct contact with an animal. Salmonella that are resistant to antimicrobial drugs can transfer resistance genes to other microorganisms. In this work, the resistance of 10 Salmonella isolates from poultry meat to 8 different antimicrobial substances was examined by the disk diffusion method. All Salmonella isolates were sensitive to trimethoprim-sulfamethoxazole and chloramphenicol. All isolates were resistant to amoxicillin and significant percentages were resistant to other antimicrobial drugs. Also, multi-drug resistance of Salmonella isolates was found. The best prevention of salmonellosis in humans is constant and comprehensive control of this hazard in food products during production, processing, storage, and sale.
