Characteristics and Lytic Activity of Phage Derived Peptidoglycan Hydrolase, LysSAP8, as a Potent Alternative Biocontrol Agent for Staphylococcus aureus.

In this study, we have suggested that LysSAP8 could be a potent alternative as a biocontrol agent that can be used to combat MRSA. PMID: 31635440 [PubMed - as supplied by publisher]

In this study, chlorhexidine (CHX)–silver (Ag) hybrid nanoparticles (NPs) coated gauze was developed, and their bactericidal effect and in vivo wound healing capacities were tested. A new method was developed to synthesise the NPs, wherein Ag nitrate mixed with sodium (Na) metaphosphate and reduced using Na borohydride. Finally, CHX digluconate was added to form the hybrid NPs. To study the antibacterial efficacy of particles, the minimal inhibition concentration and biofilm degradation capacity against Gram-positive and Gram-negative bacteria was studied using Escherichia coli and Staphylococcus aureus. The results ...

Publication date: Available online 15 January 2020Source: Journal of Theoretical BiologyAuthor(s): Sungwoo Ahn, Leonid L. RubchinskyAbstractThe mechanisms and properties of synchronization of oscillating ecological populations attract attention because it is a fairly common phenomenon and because spatial synchrony may elevate a risk of extinction and may lead to other environmental impacts. Conditions for stable synchronization in a system of linearly coupled predator-prey oscillators have been considered in the past. However, the spatial dispersion coupling may be relatively weak and may not necessarily lead to a stable, ...

In this work, an electric field was introduced into wet air oxidation (WAO) process for the efficient degradation of isophorone (IP) wastewater for the first time, named as wet electrocatalytic oxidation (WEO) process. Different composite electrodes including Ti/PbO2, Ti/Pt, Ti/Ru-Ir and Ti/Ir-Ta ...

Conclusions: We present the most detailed genomic analysis of MRSA isolated in Sri Lanka to date. The analysis identified a PVL-positive ST5-MRSA-IVc that is prevalent among MRSA causing clinical infections in Sri Lanka. Furthermore, this clone was also found among isolates from the United Kingdom and Australia. Introduction Worldwide, Staphylococcus aureus is the primary causative agent of community-acquired skin and soft tissue infections (SSTI) and is an important cause of hospital-associated invasive infections including bacteremia, pneumonia and endocarditis (Bell et al., 2002; David and Daum, 2010). Panton-Va...

Publication date: December 2017 Source:Food Research International, Volume 102 Author(s): H.M. Manukumar, S. Umesha In recent years much attention has been devoted to active packaging technologies that offer new opportunities for the food industry and food preservation. The spoilage of food products during post process handling leads to food contamination and causes life-threatening food-borne illness. The methicillin-resistant Staphylococcus aureus (MRSA) 090 is one of the food-borne pathogens associated with food poisoning that leads to an outbreak of perilous human infections worldwide. The development of resistance in...

Abstract Methicillin‐resistant Staphylococcus aureus (MRSA) is a major cause of severe healthcare‐associated (HA) infections. Although during the last decade the incidence of HA invasive infections has dropped, the incidence of community‐associated MRSA (CA‐MRSA) infections has risen among the general population. Moreover, CA‐MRSA, livestock‐associated MRSA (LA‐MRSA) and HA‐MRSA (HA‐MRSA) can be found in foods intended for human consumption. Several studies from different geographical areas have reported the presence of enterotoxin genes in several MRSA food isolates. Molecular typing studies have reveale...

The World Health Organization is issuing a warning about a group of deadly bacteria: Recently, the WHO released its first-ever list of “priority pathogens,” a list of antibiotic-resistant bacteria that the organization says pose the greatest threat to human health. The list is divided into three categories: critical-, high- and medium-priority. Three pathogens made it into the critical-priority group. These bacteria are resistant to multiple antibiotics and pose a high risk to people in hospitals and nursing homes, the WHO says. Multidrug-resistant bacteria, sometimes called “superbugs,” are a ...
