Impact of antibiotic use in animal feeding on resistance of bacterial pathogens in humans

Abstract

With the exception of flavomycin and olaquindox, the antibiotics currently used in European countries as feed additives exert a Gram-positive spectrum of activity. Of these, tylosin and virginiamycin are known for cross-resistance to macrolides, lincosamidines and streptogramines, and avoparcin is known for cross-resistance to vancomycin and teicoplanin. The use of avoparcin in animal husbandry creates a potential reservoir of transferable, vanA-mediated glycopeptide resistance in enterococci. A study in a rural area in Germany where vancomycin-resistant enterococci (VRE) were not isolated from infected humans but found in animal husbandry has shown that VRE are disseminated via meat products and are also found in faecal samples of non-hospitalized humans. VRE of different ecological origin from Germany (hospitals, sewage, food, animal husbandry) are polyclonal as evidenced by macrorestriction patterns and multilocus enzyme electrophoresis, suggesting a wide dissemination of the vanA gene cluster. These results confirm earlier observations on the spread of the sat genes, which confer resistance to a streptothricin antibiotic which has only been used in animal feeding. The resistance determinants were later also found in Escheri...Continue Reading

Allergy & Infectious Diseases

Allergies result from the hyperreactivity of the immune system to some environmental substance and can be life-threatening. Infectious diseases are caused by organisms including bacteria, viruses, fungi and parasites. They can be transmitted different ways, such as person-to-person. Here is the latest research on allergy and infectious diseases.

Antimicrobial Resistance (ASM)

Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
