Publication date: Available online 16 July 2019Source: American Journal of Infection ControlAuthor(s): Shanice Cheatham, Dipendra Thapaliya, Mohammed Taha, Katherine Milliken, Mark R. Dalman, Jhalka Kadariya, Dylan Grenier, Tara C. SmithBackgroundMethicillin-resistant Staphylococcus aureus (MRSA) is common in medical institutions. We sought to examine the prevalence of S aureus on environmental surfaces in nursing homes and to obtain molecular information on contaminating strains.MethodsA total of 259 environmental samples were collected from 7 different nursing homes in Northeast Ohio (NEO), from suburban, urban, and rural settings. The presence of the mecA and PVL genes was determined, and spa typing was performed in order to identify molecular types.ResultsThe prevalence of S aureus was 28.6% (74/259). The prevalence of MRSA and methicillin-susceptible S aureus was 20.1% (52/259) and 8.5% (22/259), respectively. S aureus contamination in suburban, urban, and rural sites was 25.7% (38/148), 45.9% (34/74), and 5.4% (2/37), respectively. MRSA was detected in 16.9% (25/148) of suburban samples and 36.5% (27/74) of urban samples. No MRSA was found in rural samples. Nursing homes from urban areas had a significantly higher (P

Wink Multidrug resistance (MDR) causes challenging tasks in medicine. Human cancer cells, as well as microorganisms, can acquire multiresistance due to the up-regulation of efflux pumps (ABC transporters) and are difficult to treat. Here, we evaluated the effects of chlorophyll, the most abundant pigment on the globe, and its derivative, pheophytin, on cancer cells and methicillin-resistant Staphylococcus aureus (MRSA). We found that both substances have significant reversal effects on multidrug-resistant CEM/ADR5000 cells (RRpheophytin = 3.13, combination index (CI)pheophytin = 0.438; RRchlorophyll = 2.72, CIchloroph...

Orthopedic implant-related infections such as periprosthetic joint infections (PJI) and osteosynthesis related infections are a devastating problem for both patients and surgeons. Besides being potentially life-threatening, implant related infections are a socioeconomic burden due to increasing health-care expenditures, functional impairment and long-lasting disabilities 1. While Staphylococcus aureus, methicillin-resistant Staphylococcus epidermidis (MRSE), methicillin-resistant Staphylococcus aureus (MRSA), coagulase-negative Staphylococcus (CoNS), Streptococcus, and Enterococcus are mainly responsible for PJI, an increa...

The objective of this study was to evaluate hybrid meshes (Gore® Synecor, Zenapro™, Ovitex™ 1S Reinforced Bioscaffold Permanent, and Ovitex™ 1S Reinforced Bioscaffold Resorbable) compared to non-hybrid, bioresorbable synthetic mesh (Phasix™ Mesh) in a rabbit bacterial inoculation model.Materials and MethodsSubcutaneous pockets were bilaterally created in male, New Zealand White rabbits (n=25). Circular meshes (3.8 cm diameter) were implanted and inoculated with 1x106 colony forming units (CFU) of clinically-isolated methicillin-resistant Staphylococcus aureus (MRSA). A given animal received a si...

In this study we test a formulation of silver sulfadiazine, vitamin A and lidocaine (AF-SSD) for aerosol administration against biofilms of Pseudomonas aeruginosa and biofilms of methicillin-resistant (MRSA) and methicillin-sensitive (MSSA) strains of Staphylococcus aureus. The aerosol allows the administration of AF-SSD without the direct contact with the wound and avoids contamination of the product after reiterative usage. We evaluated in vitro the anti-biofilm activity of AF-SSD by carrying out different technical approaches such as resazurin assays to measure metabolic activity/viability, crystal violet staining assay...

ConclusionGenomic and epidemiological analyses indicate community-based transmission of a multiply resistant MRSA clone within South Yorkshire introduced around 2012–2013, prior to the detection of a spatial–temporal cluster associated with a distinct risk group. Surveillance data indicate continued circulation.

The goal of this study was to isolate, screen, and characterize Arctic microbial isolates from Expedition Fjord, Axel Heiberg Island, Nunavut, Canada capable of inhibiting the growth of foodborne and clinically relevant pathogens. Arctic bacteria were isolated from twelve different high Arctic habitats pertaining to active layer permafrost soil, saline spring sediments, lake sediments, and endoliths. This was achieved using (1) the cryo-iPlate, an innovative in situ cultivation device within active layer permafrost soil and (2) bulk plating of Arctic samples by undergraduate students that applied standard culturing. To mit...

Bowel perforation is a rare complication of ventriculoperitoneal (VP) shunt placement that can result in anal protrusion of a VP shunt. Retrograde migration of bacteria through the shunt can lead to central nervous system (CNS) infections, such as meningitis, most commonly caused by Escherichia coli or other enteric pathogens. Here we present a case of methicillin-resistant Staphylococcus aureus (MRSA) meningitis from transanal migration of a VP shunt.
