The COVID-19 pandemic has spread rapidly around the world; some countries have introduced controls on imported products, including testing for viral nucleic acids. In this work, the influence of disinfectants for treating various SARS-CoV-2-contaminated surfaces on the detection of viral RNA fragments in swabs from these surfaces was analyzed using quantitative RT-PCR. Quaternary ammonium salt, hydrogen peroxide, 1-propanol, and sodium salt of dichloroisocyanuric acid, as well as ultraviolet irradiation, were tested as such disinfecting agents. Our results show that without exposure to disinfectants, viral RNA can be detected on the surface of all examined materials for at least 3 days. UV irradiation or irrigation with a disinfectant containing 0.2% active chlorine had the greatest effect on the decontamination of nonporous surfaces as measured by RT-PCR of swabs from these surfaces. Irrigation with disinfectants of porous surfaces (cardboard) had practically no effect on the detection of SARS-CoV-2 RNA by RT-PCR.

Background: Healthcare staff utilize equipment that can travel from patient room to patient room. Additionally, nursing and environmental services staff may not always communicate clearly regarding cleaning. The purpose of this study was to identify if a portable UV-C tent utilized with a UV-C device (Xenex® LightStrike™ Robot) can effectively disinfect high use equipment.

Background: Children spend almost one-third of their waking hours at school. Streptococcus pyogenes (Strep A) is a common childhood bacterial infection that can progress to causing serious disease. We aimed to detect Strep A in classrooms by using environmental settle plates and swabbing of high-touch surfaces in two remote schools in the Kimberley, Western Australia.

Background: Salmonella enterica is a major cause of foodborne illness and mortality worldwide, but its presence in milk along the milk supply chain and associated public health risks are under-studied. This research was aimed to investigate the occurrence and antimicrobial susceptibility of Salmonella enterica in milk, milking environments, milkers' hands, and diarrheic patients in Wolaita Sodo, Ethiopia.
Methods: We collected 644 samples from 106 dairy farms that include direct milk from cow, bulk tank milk, milkers' hand swabs, teat surfaces swabs, farm floors swabs, milk storage containers swabs, collectors' bulk milk, retailers' bulk milk, and stool from diarrheic patients.

Purpose: To evaluate the role of Streptococcus pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Serratia marcescens, and Moraxella catarrhalis in the nasal and ocular surface flora, along with their metabolic activities in children with unilateral congenital nasolacrimal duct obstruction (CNLDO).
Methods: Swabs were taken from the bilateral inferior meatus and ocular surface of 26 children with unilateral CNLDO before probing. Nasal and ocular surface swabs from non-operated eyes of children who underwent unilateral blepharoptosis or strabismus surgery formed the control group.
