A series of experiments was conducted to identify the molecular species responsible for surface active emulsification (surfactant) bioactivity in Bacillus subtilis subsp. subtilis strain ATCC PTA‐125135, and to describe culture conditions to support the enriched production of said bioactivity in cultured plaque of the strain. The assay for methylene blue active substances (MBAS) was found to be suitable

The preference of biofloculants over chemical flocculants in water and wastewater remediation systems have gained wider attention due to their biodegradability, innocuousness, safety to human and environmental friendliness. The present study aimed to evaluate research outputs on bioflocculant potentials in wastewater remediation from 1990 – 2019 using bibliometric analyses. To the best of our knowledge

α‐Mangostin rich extract (AME) exhibited satisfactory inhibitory activities against all tested MRSA strains, with minimum inhibitory concentrations (MICs) of 7.8‐31.25 µg/mL, while lawsone methyl ether (LME) and ampicillin revealed weak antibacterial activity with MICs of 62.5‐125 µg/mL. However, the combination of AME and LME showed synergistic effects against all tested MRSA strains with fractional

The present study was planned to detect the genes encoding carbapenemases, ESBLs and class 1 integron‐integrase among bacteria obtained from retail goat meat. Fermenting‐and non‐fermenting bacterial isolates (n=57), recovered from 61 goat meat samples were identified by 16S rRNA gene sequencing. Antimicrobial susceptibility of isolates was tested by the broth dilution method using ceftazidime, cefotaxime

Malaria is a worldwide serious‐threatening infectious disease caused by Plasmodium and the parasite resistance to antimalarial drugs has confirmed a significant obstacle to novel therapeutic antimalarial drugs. In this article, we assessed the antioxidant and anti‐inflammatory activity of nanoparticles prepared from Indigofera oblongifolia extract (AgNPs) against the infection with Plasmodium chabaudi

There have been numerous reports in the literature describing the diversity of microbial flora isolated from woodwind and brass instruments, with potential infection risks for players, especially when such instuments are shared. Steam disinfection has become established as a trusted method of decontamination, however, there have been no reports on the employment of this technology to disinfect parts

The reported numbers of Covid‐19 cases and deaths were compared for 18 countries (14 in Western Europe, plus Australia, Brazil, Israel and the USA) to assess the effect of historic and current national BCG immunizations. In view of the high death rate for Covid‐19 patients over 70 years of age, and given the fact that BCG vaccination is typically given early in life, we compared countries that had

Tuberculosis (TB), as a common infectious disease, still remains the severe challenges to public health. Due to the unsatisfied clinical needs of currently available diagnostic vehicles, it is desired to establish a new approach for universally detecting Mycobacterium tuberculosis . Herein, we designed a real‐time recombinase polymerase amplification (RPA) technology for identifying Mycobacterium tuberculosis

The present study was aimed at determining antimicrobial susceptibility by a CLSI standard microdilution testing protocol and detecting the resistance genes of motile Aeromonas species isolated from cultured fish. The importance of the minimum inhibitory concentrations was assessed based on statistically determined epidemiological cut‐off values calculated by normalized resistance analysis. Unfortunately

Following the appearance of several antimicrobial agents to control the spread of infections, two major challenges have emerged: 1‐ the occurrence and blowout of multiresistant bacteria and the increase of chronic diseases, and 2‐ difficult‐to‐eradicate infections. In this study, we tested five benzoylthiourea derivatives for their ability to inhibit and stop bacterial growth and evaluated the possible

This study investigated the effects of dietary Bifidobacterium bifidum (BFD) and mannan‐oligosaccharide (MOS), as a synbiotic, on the production performance, gut microbiology, serum biochemistry, antioxidant profile, and health indices of broiler chicken. Six dietary treatments were T1 (negative control), T2 (positive control‐20 mg antibiotic BMD/kg diet; BMD: bacitracin methylene disalicylate), T3

Staphylococci from Sheedal of Northeast India was isolated, identified and characterized. All the isolated Staphylococci were found to be coagulase‐negative. Based on the rpoB gene sequences followed by analysis using NCBI‐BLAST software, seven species of Staphylococcus namely, S. piscifermentans, S. condimenti, S. arlettae, S. sciuri, S. warneri , S. nepalensis and S. hominis were recognized. Phylogenetic

In the article, S. Gupta et al . (2015), in the original published version the correct name of the fourth author should be P. Priyanka and not P. Malik. The online version has been corrected. The author apologizes for this error and any confusion it may have caused.

Bacterial infection remains the main cause of Acute Respiratory Distress Syndrome (ARDS) and is a leading cause of death and disability in critically ill patients. Here we report on the use of purified β‐glucan (Lentinan) extracts from Lentinus edodes (Shiitake) mushroom that can reduce infection by a multidrug‐resistant clinical isolate of K. pneumoniae in a rodent pneumonia model, likely through

The objective was to carry out cytotoxicity assays in Vero cells and cytokines analyses in Balb/c mice as safety assessments to evaluate the probiotic mixture (M) S. cerevisiae RC016 (Sc) and L. rhamnosus RC007 (Lr) for use as feed additive. Vero cells (104 cells well‐1) were exposed to Sc (2.08 x 107, 2.08 x 106; 2.08 x 105 cells mL‐1), Lr (8.33 x 107; 8.33 x 106; 8.33 x 105 cells mL‐1) and their

Escherichia coli normally cannot grow in the environment. One environmental stress that prevents E. coli growth may be the competition for growth substrates with co‐existing microorganisms. In this study, the growth substrates of E. coli were screened by high resolution mass spectrometry and compared with those of indigenous bacteria in river water. In an incubation experiment, E. coli multiplied in

Enterococcus faecalis (E. faecalis ) is the dominant pathogen for persistent periapical periodontitis. The chlorhexidine (CHX) is used as conversional irrigation agents during endodontic root canal therapy. It was reported that the antisense walR RNA (ASwalR ) suppressed the biofilm organization. The aim of this study was to investigate the antimicrobial effects of novel graphene oxide (GO)‐polyethylenimine

Although, the application of tannic acid (TA), gallic acid (GA), natural hydrolyzable tannins (HT) rich ingredients, and HT rich feeds in ruminant feeding have been explored in order to modify or manipulate microbial activities of digestive tract of animals, the interaction between HT and gastrointestinal microbiota and the fate of HT metabolites (GA, ellagic acid, pyrogallol, resorcinol, phloroglucinol

Pediococcus pentosaceus, a bacterium recently used in human and animal probiotics, was used in combination with supports made from Polylactic acid (PLA) composite soybean meal was usedto study biofilm formation, and it was found that dense biofilms developed by Day 1. Proteomic comparison between planktonic and biofilm cultures of P. pentosaceus showed distinct expression patterns of intracellular

The present work intended to evaluate the applicability of photodynamic inactivation (PDI) of Xanthomonas citri subsp. citri with toluidine blue O (TBO), a commercial photosensitizer, as a strategy to control citrus canker.

Here we present pRH030, a new CRISPR‐Cas9 tool for the genetic engineering of Bacillus phages and beyond. It is based on the Streptococcus pyogenes cas9 with its native constitutive promoter, tracrRNA, and a gRNA precursor. The constitutive expression of Cas9 was conducive to the inactivation of viral attackers and enhanced phage mutagenesis efficiency up to 100%. The gRNA precursor can be built‐up

Blown pack spoilage (BPS) of vacuum packaged beef is caused by psychrotolerant and psychrophilic Clostridium species (PPC), primarily Clostridium estertheticum and Clostridium gasigenes . The aim of this study was to investigate the environmental niches and impact of season on these BPS Clostridium spp. on Irish beef farms. On each of 5 different beef farms, faecal (10), soil (5), silage (5), bedding
