Letter Citation - WoS: 1Citation - Scopus: 1Evaluating Ethanol Concentrations Against Staphylococcus Spp: a Proposal for Improving Nosocomial Bacteria Control(Elsevier, 2024) Soyer, Ferda; Özdemir, Özgün Öykü; Polat, Bengi; Ekenel, Nil HazalDear Editor, Nosocomial infections originating from commonly encountered pathogenic bacteria, notably Staphylococcus species, persist as a prominent global public health issue. This phenomenon exerts consequential impacts on both the well-being of patients and the healthcare personnel within hospital environments. Hospital-acquired infections from common bacteria like Staphylococcus remain a global public health concern. The European Centre for Disease Prevention and Control reports prevalence rates of 4.5% in the USA and 7.1% in Europe [1]. An estimated 8.9 million healthcare-associated infections occur annually in European hospitals and long-term care facilities [1]. According to the World Health Organization, although 10% of patients get healthcare-associated infections, at least a 30% reduction can be achieved through adequate infection prevention and control [2]. The efficacy of disinfection methodologies employed in healthcare institutions assumes critical significance in mitigating this threat.Article Citation - WoS: 11Citation - Scopus: 9Quantification of Staphylococcus Aureus in White Cheese by the Improved Dna Extraction Strategy Combined With Taqman and Lna Probe-Based Qpcr(Elsevier Ltd., 2014) Kadiroğlu, Pınar; Korel, Figen; Ceylan, ÇağatayFour different bacterial DNA extraction strategies and two different qPCR probe chemistries were studied for detection of Stapylococcus aureus from white cheeses. Method employing trypsin treatment followed by a commercial kit application and TaqMan probe-based qPCR was the most sensitive one detecting higher counts than standards in naturally contaminated samples.Article Citation - WoS: 49Citation - Scopus: 55Effects of Nisin and Lysozyme on Growth Inhibition and Biofilm Formation Capacity of Staphylococcus Aureus Strains Isolated From Raw Milk and Cheese Samples(International Association for Food Protection, 2012) Sudağıdan, Mert; Yemenicioğlu, AhmetEffects of nisin and lysozyme on growth inhibition and biofilm formation capacity of 25 Staphylococcus aureus strains isolated from raw milk (13 strains) and cheese (12 strains) were studied. Nisin was tested at concentrations between 0.5 and 25 μg/ ml; the growth of all strains was inhibited at 25 μg/ml, but the resistances of strains showed a great variation at lower nisin concentrations. In contrast, lysozyme tested at concentrations up to 5.0 mg/ml showed no inhibition on the growth of strains. Nisin used at the growth inhibitory concentration prevented the biofilm formation of strains, but strains continued biofilm formation at subinhibitory nisin concentrations. Lysozyme did not affect the biofilm formation of 19 of the strains, but it caused a considerable activation in the biofilm formation capacity of six strains. Twelve of the strains contained both biofilm-related protease genes (sspA, sspB, and aur) and active proteases; eight of these strains were nisin resistant. These results suggest a potential risk of S. aureus growth and biofilm formation when lysozyme is used in the biopreservation of dairy products. Nisin can be used to control growth and biofilm formation of foodborne S. aureus, unless resistance against this biopreservative develops. Copyright ©, International Association for Food Protection.
