Ozonated water is a possible handwashing alternative to antimicrobial soap and water. In a previous report, 4 ppm of ozonated water removed artificially contaminated bacteria from the hands of healthy volunteers as effectively as antimicrobial or non-antimicrobial soap and water. Currently, there is a lack of data on the efficacy of ozonated water in removing bacteria from hands loaded with organic materials.

Introduction. Carbapenem resistant Enterobacterales (CRE) are one of the leading causes of systemic and nosocomial infections and are multidrug-resistant organisms producing different carbapenemases.

Abstract

Heavy metal (HM) pollution is a worldwide environmental issue. Given the urgent need to develop more powerful approaches for effective phytoremediation of HMs, isolation of novel endophytic strains from hyperaccumulator plants having potent HM tolerance is the main objective in this research. Moreover, the recovered strains were characterized and subjected to radiation mutagenesis to enhance their tolerance to HMs.

Six bioretention filter columns were designed to study the effects of the bioretention system on surface runoff reduction through rainfall simulation water distribution experiments, and the relationship between the physicochemical properties of contaminated fillers and microbial community structure was analyzed.

This study was conducted to determine the occurrence of antimicrobial resistance to the extended-spectrum cephalosporins (ESC) in Escherichia coli isolates. The isolates were collected from retail meat products collected in the Maritime Provinces of Canada. Our analyses involved the use of both selective and traditional culture methods; we also conducted genotype analyses using multiplex polymerase chain reactions. ESC-resistant (ESC-R) E.

Mycotoxins, toxins of fungal origin, can directly or indirectly contaminate food and feed and are poisonous to livestock and humans. While a large amount is known about their occurrence in crops, food, and feeds, little is known about mycotoxin amounts in soil. However, soil is known as a major fungal habitat and a potential sink for mycotoxins in the environment.

This study evaluated the effects of early intervention with Clostridium butyricum (C. butyricum) on shaping the intestinal microbiota of Muscovy ducklings. A total of 160 1-day-old male ducks were randomly divided into two groups: the CB group was administered with 1 mL of C. butyricum (2 × 109 CFU/mL), while the C group was given 1 mL of saline. The administration lasted for 3 days. We found that C. butyricum had no significant effect on growth performance.

Journal of Basic Microbiology, EarlyView. In this study, lead (Pb) biosorption studies in aqueous solution were performed with metal-resistant Bacillus strain MRS-2 (ATCC 55674) bacterium which was previously isolated from wastewater plant. It showed minimum inhibition concentration of 300 ppm Pb on the nutrient agar plates.

Letters in Applied Microbiology, Accepted Article. The immunogenicity of soluble OmpK- small ubiquitin-like modifier, OmpK inclusion bodies, formalin, and heat-killed V. parahaemolyticus cells were prepared and studied in a mouse model. The results of whole-cell ELISA and western blot (WB) revealed that the serum against soluble OmpK and OmpK inclusion bodies reacted only with homologous V. parahaemolyticus.

Aquaculture Nutrition, EarlyView. A 56-day feeding try was conducted to evaluate the effects of processed garlic known as black garlic (BG) fed at different inclusion levels (0 (BG0, control), 5 (BG0.5), 10 (BG1), 20 (BG2), 40 (BG4), and 80 (BG8) g/kg feed) on the growth, whole body composition, immune and antioxidant enzyme activities, gut microbiota and resistance to Vibrio parahaemolyticus infections in Litopenaeus vannamei (initial weight = 0.60 ± 0.001 g).

Oysters are one of the main aquatic products sold in coastal areas worldwide and are popular among consumers because of their delicious taste and nutritional value. However, the microorganisms present in oysters may pose health risks to consumers. In this study, the microbial communities of Pacific oysters (Crassostrea gigas) collected from aquatic product markets in three cities (Guangzhou, Zhuhai, and Jiangmen) of Guangdong Province, China, where raw oysters are popular, were investigated.

Serratia marcescens is a bacterial species widely found in the environment, which very efficiently colonizes mosquitoes. In this study, we isolated a red-pigmented S. marcescens strain from our mosquito colony (called S. marcescens VA). This red pigmentation is caused by the production of prodigiosin, a molecule with antibacterial properties. To investigate the role of prodigiosin on mosquito-S. marcescens interactions, we produced two white mutants of S. marcescens VA by random mutagenesis.

Contamination of fomites by human norovirus (HuNoV) can initiate and prolong outbreaks. Fomite swabbing is necessary to predict HuNoV exposure and target interventions. Historically, swab recovered HuNoV has been measured by molecular methods that detect viral RNA but not infectious HuNoV. The recent development of HuNoV cultivation in human intestinal enteroids (HIEs) enables detection of infectious HuNoV.

Objective

The objective of the study was to investigate the antimicrobial susceptibility and extended-spectrum beta-lactamase (ESBL) positive rates of Escherichia coli from community-acquired urinary tract infections (CA-UTIs) in Chinese hospitals.

Materials and Methods

ABSTRACT Hepatitis E virus (HEV) is worldwide distributed and might cause acute or chronic hepatitis mainly in immunocompromised individuals. In previous studies we found a high prevalence of antibodies to HEV within blood donors in south Brazil and also within backyard-raised pigs.
