“…Lopez et al [10] have recovered E. gallinarum and E. casseliflavus in 12% of dog and healthy human faecal samples. Çetinkaya et al [7] have detected MIC values higher than 256 µg/ml for vancomycin and teicoplanin in E. gallinarum, E. avium isolates. There is no particular protocol suggested by CDC for the patients that are infected or colonized by E. gallinarum.…”

“…In the last decade, studies on examination of nosocomial infectious agents such as methicillin resistant staphylococci, vancomycin resistant enterococci in different animals started to have clinical concern. The emergence of resistance to vancomycin has presented an increasingly important problem in treatment [1,2,[5][6][7][8][9][10] . Various genes including vanA, vanB, vanC, vanD, vanE, van G, vanN and vanM encode vancomycin resistance among enterococci.…”

“…Recent molecular epidemiological studies suggest that VRE residing the gastrointestinal flora of animals can be a source of infection for human. Many researchers report that those VRE can be transmitted to human via contaminated raw or insufficiently treated food, or after a physical contact with a companion animal such as cats and dogs [7,10,12,13] . This study aims to detect VRE occurrence in various animals, to examine antimicrobial resistance profiles phenotypically, and to determine the distribution of vancomycin resistant genes, vanA, vanB, vacC1, vanC2/C3.…”

Infections caused by Vancomycin Resistant Enterococci (VRE) are important in human medicine in terms of treatment difficulties. Molecular studies in the last years revealed that VRE occurrence in animals might be important in epidemiology of infections in human. This study aims to detect VRE occurrence in various animals, examine antibiotic resistance profiles phenotypically, and determine the distribution of the vancomycin resistant genes, vanA, vanB, vacC1, vanC2/C3. For this purpose, rectal swabs were collected from farm and companion animals; and cloacal swab or litter were collected from chickens and they were processed for VRE isolation. Following the identification of the isolates, antimicrobial susceptibilities of the isolates were determined in accordance with the Clinical and Laboratory Standards Institute (CLSI) standards. Distribution of the vancomycin resistant genes; vanA, vanB, vanC1 and vanC2/C3 among enterococcus species and different animal species were determined by multiplex PCR. VRE were isolated from 17% of the feline samples, 20% of each of the other species, and 19% of all the samples. Those isolates were identified as E. casseliflavus (n=39), E. gallinarum (n=55) and E. faecium (n=3) as a result of multiplex-PCR. According to the antimicrobial susceptibility tests, most of the isolates were found to be resistant to penicillin G, ciprofloxacin and erythromycin. Eighteen (18.8%) of the isolates were found to be resistant against two antibiotic groups, while 69 (71 %) of them were resistant to three or more antibiotics. Keywords

The 2011 listeriosis outbreak attributed to whole cantaloupe involved several genetically distinct strains of serotypes 1/2a and 1/2b that had not been previously reported in invasive listeriosis outbreaks. Here we investigated the potential of strains from the 2011 cantaloupe outbreak to adhere, survive, and grow on cantaloupe rind and flesh and in juice extracted from cantaloupe at different temperatures (4, 8, and 25°C). All strains were able to adhere and grow, with ∼10-fold increases after 7 days at 4 or 8°C and after 24 h at 25°C, with a propensity for more growth on rind than on flesh or in extract. No significant differences in growth potential were noted among the different strains or between them and unrelated strains from other listeriosis outbreaks involving celery, deli meats, or hot dogs. Similarly to the cantaloupe outbreak strains, these other strains exhibited greater propensity for growth on rind than on flesh or in extract. Rinsing of cantaloupe fragments in sterile water resulted in temporary reductions of the populations by 50- to 100-fold, suggesting the potential of such washing to reduce risk if the produce is promptly consumed. The absence of marked differences in adherence or growth between the cantaloupe outbreak strains and strains from other outbreaks highlights the need to further characterize the 2011 cantaloupe outbreak strains and elucidate potential biological attributes that contributed to their implication in the outbreak.

“…Vancomycin is a antibiotic, strongly affects Gram-positive bacteria for the treatment of serious, life-threatening infections, when other antibiotic treatment did not work (Varela et al, 2013). Vancomycin resistance in enterococci have been occured all over the world since 1986 (Cetinkaya et al, 2013). Vancomycin resistance was described six phenotypes as vanA, vanB, vanC, vanD, vanE and vanG. VanA type strains possess high-levels of resistance to vancomycin and teicoplanin.…”

Abstract:The aim of this study was to determine the incidence of vancomycin-resistant enterococci (VRE) in tap and artesian well waters and to detect the vancomycin resistance genes and virulence genes of the isolates obtained from the samples. For this purpose, 200 samples (119 tap and 81 artesian well waters) were collected from several water supplies during November 2013 and June 2015 period in Bursa province. Seven isolates were recovered from artesian well waters and confirmed as Enterococcus by PCR method. E-test performed for vancomycin and teicoplanin MIC values indicated that only two isolates had the intermediate-level (8 μg/mL) resistance to vancomycin. No resistance was observed to teicoplanin in any of these isolates by Etest. All of 7 isolates were tested for vancomycin resistance genes (vanA, vanB and vanC) and virulence genes (gelE, agg, esp and ace). The results showed that enterococci isolates had no these genes. The present study suggested that the presence of the intermediate level VRE in artesian well waters and, also the waters from environmental supplies near human and animal niches could be play a role as potential reservoirs for enterococci having several types of resistance to vancomycin. Also, vancomycin resistant strains can be possible the spread in environment and also the transmission to human and animals through contaminated water sources.
