“…Staphylococcus cohnii , for example, has been show to be an opportunistic pathogen with high morbidity in people with a compromised immune system [52-54]. Moreover, antibiotic-resistant clinical isolates [55] have been reported, as have those with antibiotic resistance plasmids [56]. Staphylococcus cohnii has also been reported as a false positive for MRSA on specialized chromogenic media [57].…”

ObjectivesOur goal was to determine the diversity and abundance of Staphylococcus bacteria on different components of a public transportation system in a mid-sized US city (Portland, Oregon) and to examine the level of drug resistance in these bacteria.MethodsWe collected 70 samples from 2 cm × 4 cm sections from seven different areas on buses and trains in Portland, USA, taking 10 samples from each area. We isolated a subset of 14 suspected Staphylococcus spp. colonies based on phenotype, and constructed a phylogeny from16S rRNA sequences to assist in identification. We used the Kirbye–Bauer disk diffusion method to determine resistance levels to six common antibiotics.ResultsWe found a range of pathogenic Staphylococcus species. The mean bacterial colony counts were 97.1 on bus and train floors, 80.1 in cloth seats, 9.5 on handrails, 8.6 on seats and armrests at bus stops, 3.8 on the underside of seats, 2.2 on windows, and 1.8 on vinyl seats per 8 cm2 sample area. These differences were significant (p < 0.001). Of the 14 isolates sequenced, 11 were staphylococci, and of these, five were resistant to penicillin and ampicillin, while only two displayed intermediate resistance to bacitracin. All 11 isolates were sensitive to trimethoprim-sulfamethoxazole, vancomycin, and tetracycline.ConclusionsWe found six different strains of Staphylococcus, and while there were varying levels of drug resistance, we did not find extensive levels of multidrug-resistant bacteria, and no S. aureus was found. We found floors and cloth seats to be areas on buses and trains that showed particularly high levels of bacteria.

“…More importantly, most of these species are resistant to methicillin, which also refers to the fact that they are resistant to other beta-lactam antibiotics at the same time. It is also known that methicillin resistance in CoNS plays a role in transferring to other CoNS (Szewczyk et al 2003, Szewczyk et al 2004, Lis et al 2009, Bagcigil et al 2012. Due to the known importance of staphylococci and methicillin resistance in public health, apart from studying culturable airborne bacteria, investigations of methicillin resistant S. aureus MRSA were also targeted during this study.…”

This study is aimed to investigate culturable airborne bacteria concentrations and the composition of methicillin-resistant staphylococci in eleven different locations on the basis of specifi c activities conducted within different parts of the European side of Istanbul. The highest bacterial levels were observed at the Bakirkoy station (1 100 CFU/m 3 ) while the second highest levels were found at the Bahcelievler station (1 040 CFU/m 3 ) in October; the lowest levels (10 CFU/m 3 ) were measured at other different stations (Atakoy, Yesilkoy). Fifteen methicillin--resistant isolates [Staphylococcus hominis (n=11), S. cohnii spp. cohnii (n=2), S. sciuri (n=1), S. capitis spp. capitis (n=1)] were identifi ed. The disc diffusion method was used to identify the antimicrobial resistance of these isolates, it was observed that the most common resistance was to penicillin (P) (n=11), doxycycline (DO) (n=4) and tetracycline (T) (n=5). None of the isolates was resistant to imipenem, amoxicillin/clavulanic acid, vancomycin (IPM, AMC, VA). However, multiple antimicrobial resistance was found to be 26.7%. The results of this study revealed the importance of isolated methicillin-resistant staphylococci in the stations with densely active human population and traffi c, for public health. As a result, the importance of resting along known shorelines, where culturable airborne bacteria concentrations are much lower, and its importance for human health have been emphasized.

“…Genes encoding antibiotic resistance are usually located on mobile genetic elements, which means that their transfer to pathogenic staphylococcal species is possible. According to Kloos (1997) and Szewczyk et al (2004) S. hominis, and S. cohnii frequently present in clinical samples are considered as a reservoir of resistance genes in the environment. It is surmised that non-S. aureus staphylococci carrying antibiotic resistance genes significantly contribute to the evolution of MRSA in both hospital and community settings (Kassem 2011).…”

Prevalence of mecA, blaZ, tetO/K/M, ermA/B/C, aph, and vanA/B/C/D genes conferring resistance to oxacillin, penicillin, tetracycline, erythromycin, gentamicin, and vancomycin was investigated in 65 staphylococcal isolates belonging to twelve species obtained from ready-to-eat porcine, bovine, and chicken products. All coagulase negative staphylococci (CNS) and S. aureus isolates harbored at least one antibiotic resistance gene. None of the S. aureus possessed more than three genes, while 25% of the CNS isolates harbored at least four genes encoding resistance to clinically used antibiotics. In 15 CNS isolates the mecA gene was detected, while all S. aureus isolates were mecA-negative. We demonstrate that in ready-to-eat food the frequency of CNS harboring multiple antibiotic resistance genes is higher than that of multiple resistant S. aureus, meaning that food can be considered a reservoir of bacteria containing genes potentially contributing to the evolution of antibiotic resistance in staphylococci.
