Abstract

Antibiotic resistance is considered a global public health problem and is related to the problem of resistance of bacteria in human and veterinary medicine that are transmitted directly and through the food chain. Uncontrolled use of antibiotics in veterinary practice is a special danger for the development of antibiotic resistance. The problem of public health, human and veterinary is the acquired resistance of bacteria to antibiotics. Of particular importance is the emergence of multidrug resistance to Escherichia coli, which is becoming more common in the world, both in human and veterinary medicine, and the possible transmission of resistant Escherichia coli between animals and humans. The purpose of this paper is to show the importance of the rational use of antibiotics in animals and humans to prevent the spread of antibiotic resistance. Escherichia coli is an intestinal bacterium of all mammals, widespread in the environment and often present in food of animal origin. Today, a pluripotent bacterium and a carrier of antibiotic resistance genes due to anthropogenic factors, and genes are transmitted through animal bacteria, food bacteria to bacteria of human origin.

Abstract

Campylobacter jejuni is a colonizer of the intestines of animals, but the highest prevalences were recorded in the cecum of broiler chickens. Production errors contribute to the prevalence of broiler carcasses exceeding permitted norms, which increases the incidence of consumer disease from campylobacteriosis, a foodborne disease. In order to prevent people from getting sick, many producers resort to the prophylactic use of antibiotics in broilers, but this practice leads to antibiotic resistance. The aim of the work is to outline the possibility of using oregano oil as an alternative to antibiotics in order to reduce the colonization of the cecum with Campylobacter jejuni in broiler chickens, which will contribute to the microbiological integrity of chicken meat, but also to reduce the spread of antibiotic resistance. In vitro tests show the antibacterial activity of oregano oil and its main antibacterial component carvacrol on Campylobacter jejuni isolates from the cecum of broiler chickens, and in vivo tests throughout the fattening period indicate a significant reduction in cecal colonization in the first, but not the last, days of fattening, suggesting the importance of further tests.
