“…Out of the 130 MRSA isolates, MRSA was isolated alone from 77 cultures (59.2%) while MRSA was isolated with another organism from 53 cultures (40.8%). Gram negative bacilli were common co-pathogens that are resistant to VA required for the MRSA treatment, so they may need to be treated by β-lactam antibiotics which may induce VA resistance among MRSA isolates 30,31 .…”

The relative high burden of morbidity and mortality caused by Staphylococcus aureus (SA) in healthcare and community settings is a major concern worldwide. It can cause invasive infections, sepsis and deaths. Despite progress in methicillin-resistant S. aureus (MRSA) prevention in healthcare settings, there is a critical need for assessment of the problem in both healthcare and community settings. This study was conducted for examining the prevalence, risk factors and antimicrobial susceptibility of MRSA in Mansoura University Hospitals (MUHs), Egypt. Samples were collected from patients in MUHs with clinically suspected nosocomial infections. MRSA isolates were identified by the standard bacteriological methods, biochemical reactions and disc diffusion method as recommended by the Clinical & Laboratory Standards Institute (CLSI), then confirmed by MecA gene PCR. A total of 2006 isolates was obtained. SA (32%) was the most frequently isolated pathogen. MRSA (130 isolates) represented 20% of SA and 6.48 % of all isolates. The mecA PCR identified SA as MRSA in 99.2% of cases. MRSA was isolated with another organism (mostly Gram-negative bacilli) from 40.8% of cases while 59.2% of MRSA was isolated alone. The most important reported risk factors for MRSA infections were prolonged hospital stays, recent antibiotic therapy, ICU admission, indwelling devices and presence of surgical sutures. MRSA was resistant to many antibiotics but sensitive to vancomycin in 99.2% of cases. Minimizing exposure to the risk factors with rapid diagnosis of MRSA infections are essential for early initiation of appropriate antibiotic treatment and limitation of the non-optimal use of glycopeptides and deaths.

Although self-service facilities (SSFs) have been used on a large scale worldwide, they can be easily contaminated by microorganisms from the hands of their sequential users. This research aimed to study the prevalence and antimicrobial susceptibility/resistance of bacteria contaminating SSFs in Sakaka, Aljouf, Saudi Arabia. We randomly swabbed the surfaces of 200 SSFs, then used the suitable culture media, standard microbiological methods, and the MicroScan WalkAway Microbiology System, including the identification/antimicrobial susceptibility testing-combo panels. A high SSFs’ bacterial contamination load was detected (78.00%). Ninety percent of the samples collected in the afternoon, during the maximum workload of the SSFs, yielded bacterial growth (p < 0.001 *). Most of the contaminated SSFs were supermarket payment machines, self-pumping equipment at gas stations (p = 0.004 *), online banking service machines (p = 0.026 *), and barcode scanners in supermarkets. In the antiseptic-deficient areas, 55.1% of the contaminated SSFs were detected (p = 0.008 *). Fifty percent of the contaminated SSFs were not decontaminated. The most common bacterial contaminants were Escherichia coli (70 isolates), Klebsiella pneumoniae (66 isolates), Staphylococcus epidermidis (34 isolates), methicillin-resistant Staphylococcus aureus (18 isolates), and methicillin-sensitive Staphylococcus aureus (14 isolates), representing 31.53%, 29.73%, 15.32%, 8.11%, and 6.31% of the isolates, respectively. Variable degrees of reduced sensitivity to some antimicrobials were detected among the bacterial isolates. The SSFs represent potential risks for the exchange of antimicrobial-resistant bacteria between the out-hospital environment and the hospitals through the hands of the public. As technology and science advance, there is an urgent need to deploy creative and automated techniques for decontaminating SSFs and make use of recent advancements in materials science for producing antibacterial surfaces.
