Antibiotic resistance among Listeria, including Listeria monocytogenes, in retail foods
Abstract
In the past eight to 10 years, reports of antibiotic resistance in food-borne isolates in many countries have increased, and this work examined the susceptibility of 1001 food isolates of Listeria species. Susceptibility/resistance to eight antibiotics was determined using the Bauer-Kirby disc diffusion assay, and 10.9% of the isolates examined displayed resistance to one or more antibiotics. Resistance to one or more antibiotics was exhibited in 0.6% of Listeria monocytogenes isolates compared with 19.5% of Listeria innocua isolates. Resistance was not observed in Listeria seeligeri or Listeria welshimeri. Resistance to tetracycline (6.7%) and penicillin (3.7%) was the most frequently observed, and while resistance to one antibiotic was most common (9.1%), isolates resistant to two or more antibiotics (1.8%) were also observed. While resistance to the antibiotics most commonly used to treat human listeriosis was not observed in L. monocytogenes, the presence of such resistance in other Listeria species raises the possibility of future acquisition of resistance by L. monocytogenes. The higher level of resistance in L. innocua compared with L. monocytogenes suggests that a species-related ability to acquire resistance to antibio...Continue Reading

Allergy & Infectious Diseases (ASM)
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.
Antifungals
An antifungal, also known as an antimycotic medication, is a pharmaceutical fungicide or fungistatic used to treat and prevent mycosis such as athlete's foot, ringworm, candidiasis, cryptococcal meningitis, and others. Discover the latest research on antifungals here.
Antimicrobial Resistance (ASM)
Antimicrobial resistance poses a significant threat to the continued successful use of antimicrobial agents for the treatment of bacterial infections.
