Introduction / objectives Survival of pathogens on touch surfaces contributes to increasing incidence and spread of antibiotic resistance and infection in hospitals. One way to address this could be to use biocidal surfaces in conjunction with improved cleaning regimes. Exposure to moist copper alloy surfaces, to simulate fomite contamination, resulted in a rapid kill of significant bacterial, ...

•There are significant challenges in selective media to identify carbapenem resistant enterobacteriace (CRE) from fomites. •We share our experience with HardyCHROM CRE plates and modified MacConkey agar. •Modified may be more beneficial for detection of environment. Accurately identifying fomites is critical infection control practices, research, assessing patient risk. We compared a commercial...

This paper describes the use of log-linear energy phase-space projections to analyze microwave-assisted inactivation bacteria and viruses under different fomite conditions within multimode microwave ovens. The ovens are operated at a cavity-magnetron frequency 2.45 ± 01 GHz. Porous fomites (moist face towels, cotton swabs, kitchen sponges, scrubbing pads, cigarette filters N95-like respirators)...

Adhesion of two viruses – one enveloped (human respiratory syncytial virus, HRSV) and non-enveloped adenovirus 5, HAdV5) to four fomites (silica, nylon, stainless steel, polypropylene) was quantified interpreted based on physicochemical properties fomites. The selected are tentatively identified as “archetypes” representing groups materials distinctly different in mechanisms their interfacial i...

UNLABELLED Cattle have been proposed as the natural reservoir of a novel member of the virus family Orthomyxoviridae, which has been tentatively classified as influenza D virus (IDV). Although isolated from sick animals, it is unclear whether IDV causes any clinical disease in cattle. To address this aspect of Koch's postulates, three dairy calves (treatment animals) held in individual pens wer...

Objective: To 1) characterize the decay curve of infective SARS-CoV-2 over time on surface cardboard packaging and plastic mailer packaging; 2) transferability virus-inoculated to skin. Methods: We inoculated samples with a titer > 106 TCID50/ mL evaluate survivability skin (pig skin) time. A cell culture-based infectivity assay (TCID50) was used determine viral titers. Regression analysis curv...

background: tourniquets used repeatedly on patients for blood sampling are a potential source of nosocomial infections. they harbor numerous microorganisms, including methicillin‑resistant staphylococcus aureus (mrsa). the aim of this study was to investigate tourniquets for the presence of microorganisms and to ascertain the infection control practices of health care workers. methods: a cross‑...
