Antagonistic activity of bacteriocin-like inhibitory substances from Enterococcus lactis isolated from the surface of jalapeno peppers against foodborne pathogens
The potential of Lactic acid bacteria (LAB) isolated from the surface of jalapeno peppers to produce bacteriocins with antagonistic activity against foodborne pathogens such as Listeria monocytogenes, Staphylococcus aureus, Escherichia coli O157:H7, and Salmonella Typhimurium was evaluated. Previou...

Investigation of antimicrobial, antioxidant, and cytotoxic activities of Boesenbergia rotunda rhizome extract
In recent years, antimicrobial resistance (AMR) has become a global threat to public health. In Hawaii, there is an increasing rate of staph infections of methicillin-resistant Staphylococcus aureus (MRSA), and, hence, a need for new agents to combat the increase of AMR bacteria. This study evaluate...

Hydrogen peroxide, sodium dichloro-s-triazinetriones and quaternary alcohols significantly inactivate the dry-surface biofilms of Staphylococcus aureus and Pseudomonas aeruginosa more than quaternary ammoniums
Globally, healthcare-associated infections (HAI) are the most frequent adverse outcome in healthcare delivery. Although bacterial biofilms contribute significantly to the incidence of HAI, few studies have investigated the efficacy of common disinfectants against dry-surface biofilms (DSB). The obje...

Inactivation of Listeria monocytogenes and Salmonella spp. during cooking of country ham and fate of L. monocytogenes and Staphylococcus aureus during storage of country ham slices
Viability of cells of Listeria monocytogenes, Salmonella spp., or Staphylococcus aureus was quantified following cooking or storage of country hams. Hams (average = ca. 3.4 ± 0.5 kg each; average = ca. =18% shrinkage) were used as provided by the processor (i.e., “salted hams”), or desalted in tap w...

Epidemiology of Staphylococcus aureus non-susceptible to vancomycin in South Asia
Staphylococcus aureus is one of the ESKAPE (Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter species) pathogens among which multidrug resistance has emerged. Resistance to methicillin resulted in clinicians using th...

Selective detection of Escherichia coli K12 and Staphylococcus aureus in mixed bacterial communities using a single-walled carbon nanotube-functionalized electrochemical immunosensor with dielectrophoretic concentration
An electrochemical immunosensor has been developed for the rapid detection and identification of potentially harmful bacteria in food and environmental samples. This study was to fabricate a microwire-based electrochemical immunosensor (MEI sensor) for selective detection of Escherichia coli and Sta...

Efficacy of novel staphylococcal surface associated protein vaccines against Staphylococcus aureus and non-aureus staphylococcal mastitis in dairy cows
Mastitis is an inflammation of the mammary gland commonly caused by bacteria or fungi. Staphylococcus aureus is a major bacterium that causes mastitis in dairy cows. Non-aureus staphylococci are also increasingly reported, with Staphylococcus chromogenes being the most common species. Current staphy...

Synthesis and inhibitory activity of machaeridiol- based novel anti-MRSA and anti-VRE compounds and their profiling for cancer- related signaling pathways
Three unique 5,6-seco-hexahydrodibenzopyrans (seco-HHDBP) machaeridiol A–C, reported previously from Machaerium Pers., have displayed potent activities against methicillin-resistant Staphylococcus aureus (MRSA), vancomycin-resistant Enterococcus faecium and E. faecalis (VRE). In order to enrich pipe...

Prevalence and antimicrobial resistance of escherichia coli O157:H7 and salmonella, and the prevalence of staphylococcus aureus in dairy cattle and camels under pastoral production system
Escherichia coli O157: H7 and Salmonella are common milk borne pathogens compromising the microbiological safety of raw milk. However, studies reporting on the occurrence of the pathogens in the developing countries like Ethiopia especially in pastoral production system are scarce. This study was co...

Hydrogen peroxide, sodium dichloro-s-triazinetriones and quaternary alcohols significantly inactivate the dry-surface biofilms of Staphylococcus aureus and Pseudomonas aeruginosa
more than quaternary ammoniums
Globally, healthcare-associated infections (HAI) are the most frequent adverse outcome in healthcare delivery. Although bacterial
biofilms contribute significantly to the incidence of HAI, few studies have investigated the efficacy of common disinfectants against dry-surface biofilms (DSB). The obje...

Evaluation of a witch hazel extract for the potential prebiotic and protective effect on select Lactiplantibacillus plantarum (prev. Lactobacillus plantarum) strains
Witch hazel extract has been evaluated in prior studies demonstrating the phenolic-mediated biofilm inhibition, toxin production inhibition and growth inhibition in Staphylococcus aureus. In this study we are evaluating the possible prebiotic and protective effect of witch hazel extract on select pr...

Effect of plasma-activated solution treatment on cell biology of Staphylococcus aureus and quality of fresh lettuces
This study aimed to investigate effects of plasma-activated solution (PAS) on cell biology of a Gram-positive (G+) bacterium Staphylococcus aureus and quality of fresh lettuce leaves. PAS was prepared by dielectric barrier discharge (DBD) plasma and either incubated with S. aureus for 10-30 min or w...

Genetic diversity of Staphylococcus aureus strains from a tertiary care hospital in Rawalpindi, Pakistan
Staphylococcus aureus is an important healthcare-associated bacterium that causes a multitude of infections in humans such as superficial skin and soft tissue infections, necrotizing pneumonia, foodborne illnesses and postsurgical infections. Treatment of S. aureus infections has become more complic...

Disinfectant and antimicrobial susceptibility studies of Staphylococcus aureus strains and ST398 and ST5 methicillin-resistant Staphylococcus aureus strains from swine mandibular lymph node tissue, commercial pork sausage…
Aims: Staphylococcus aureus (S. aureus) causes hospital and community diseases, and gastrointestinal illness worldwide. Disinfectants are used throughout the food chain for pathogenic bacteria control. The aims were to (i) investigate S. aureus bioavailability in swine tissue and sausage, (ii) estab...

Phylodemographic signatures in the emergence of community-associated MRSA
Community-associated, methicillin-resistant Staphylococcus aureus (MRSA) lineages have emerged in many geographically distinct regions around the world during the past 50 years. Here, we apply consistent phylodynamic methods across multiple community-associated MRSA lineages to describe and contrast...

Complete genome sequence of the methicillin-resistant Staphylococcus aureus strain SQL1/USA300, used for testing the antimicrobial properties of clay phyllosilicates and customized aluminosilicates
Methicillin Resistant Staphylococcus aureus (MRSA) is a Gram-positive bacterium with strains that cause community-acquired and nosocomial infections. Recently, we showed the antimicrobial capacity of clay components with potency to deter the virulent MRSA strain SQL1. The annotated genome contribu...
