“…Concerning animal prevalence, and despite avoparcin being withdrawn for more than 15 years, vancomycin resistance is still detected in enterococci isolated from food-producing animals, albeit at low to very low levels. Nevertheless, VRE are found in the intestinal microbiota of farm animals in Europe, whereas in the USA carriage of VRE is usually absent [ 24 ]. Different theories about why VRE persist among farm animals have been presented.…”

“…Another explanation that has been suggested is that plasmid addiction systems, “selfish” DNA sequences located on the same plasmid as the van A gene, would force the bacteria to retain the resistance by killing the plasmid-free cells [ 4 ]. Resistance to tetracyclines and erythromycin is also commonly detected among the indicator enterococci isolates from animals and food [ 24 ]. Further, in a few European studies, putative linkage of glycopeptide, macrolide, and tetracycline-resistant genes have been implicated in the occurrence of VRE in the feces of food-producing animals [ 26 , 27 ].…”

Enterococci, from Harmless Bacteria to a Pathogen

Enterococci are gastrointestinal commensals whose hardiness allowed them to colonize very diverse environments, including soils, water, food, and feed. This ability to overcome adverse conditions makes enterococci problematic once they colonize hospital niches. Together with the malleability of their genomes, the capacity to acquire and disseminate determinants of antibiotic resistance has contributed to converting what was once just another opportunistic pathogen into a first-class clinical problem. This review discusses the dimension of the emergence of enterococcal resistance to key antimicrobial agents, the dissemination of this resistance, and its significance in terms of public health, with the aim of raising awareness of the need to devise and implement surveillance programs and more effective antibiotic stewardship.

“…These genes encode changes in the amino acid sequence of the peptidoglycan precursor protein, thereby preventing vancomycin binding [ 61 ]. The relationship of food enterococci with clinical infections has not yet been clearly elucidated [ 62 ]. Foodborne enterococci are not known to be a direct source of resistant enterococci in humans but could pose a risk of transmitting resistance determinants to strains present in the human intestinal microbiota [ 60 ].…”

In recent years, several alimentary diseases have been connected with the consumption or tasting of raw flour and dough. Microbiological quality concern is also raising due to increased consumer demand for plant powders, while some of them can be consumed without prior thermal processing. In this study, we have focused on the occurrence of antibiotic-resistant coliform bacteria and enterococci in flour, plant powder and dough from Slovak retail. Our results indicated the presence of both total and antibiotic-resistant coliform bacteria and enterococci in the flour and powder samples. Lower numbers of the total, as well as resistant bacteria, were detected in flours compared to plant powders. Coliform bacteria isolates were predominantly identified as Klebsiella spp. and Enterobacter spp. Ampicillin resistance appeared in 97% of isolates followed by chloramphenicol resistance (22%) and tetracycline resistance (17%). The presence of the blaSHV gene was confirmed in 13% of isolates. The tetA and tetE genes were present in 25% of isolates of coliform bacteria. The presence of enterococci was detected only in plant powders. Antibiotic-resistant strains were identified as the following: Enterococcus casseliflavus, E. gallinarium and E. faecium. Despite the isolates showing resistance to vancomycin, the presence of the vanA gene was not detected. The majority of antibiotic-resistant isolates belonged to the group of medium biofilm producers. None of these isolates showed efflux pump overproduction. Antibiotic-resistant coliform bacteria and enterococci were not detected in the processed doughs.
