Effects of L. Seed Extracts on Multi Drug Resistant (MDR) Bacteria.

Wound infections became a great challenge, especially after the emergence of bacterial resistance to commonly used antibiotics. Medicinal plants can be the source of alternative antibacterial agents effective against multi drug resistant (MDR) bacteria. This research aimed to evaluate the effectiveness of different seed extracts in fighting MDR bacteria that infect wounds.

Comprehensive analysis of soybean cultivars' response to SMV infection: genotypic association, molecular characterization, and defense gene expressions.

Background: Soybean mosaic virus (SMV) is a devastating disease that threatens soybean plants worldwide. The different soybean genotypes displayed different responses to SMV strains. This study aimed to investigate the response of different selected soybean cultivars to SMV infection in Egypt based on their specific genetic makeup.

Evaluation of Bacillus aryabhattai B8W22 peroxidase for phenol removal in waste water effluents.

Environmental contamination by phenol has been reported in both aquatic and atmospheric environments. This study aimed to separate and purify the peroxidase enzyme from bacteria that degrade phenol from wastewater sources. An enrichment culture of MSM was used to screen 25 bacterial isolates from different water samples for peroxidase production, six of the isolates exhibited high levels of peroxidase enzyme activity.

Potential role of Spirulina (Arthrospira) platensis biomass for removal of TiO2NPs -MG hybrid nanocomposite produced after wastewater treatment by TiO2 nanoparticles.

Biosynthesis of titanium dioxide nanoparticles (TiO2NPs) by Sphingomonas paucimobilis B34 bacteria was successfully achieved and followed by UV-Vis spectroscopy. The nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and fourier transform infrared spectroscopy (FTIR) techniques. The biosynthesized TiO2NPs were spherical in shape with an average particle size of 15.

Enhanced Efficacy of Some Antibiotics in Presence of Silver Nanoparticles Against Multidrug Resistant Recovered From Burn Wound Infections.

Burn wound infections with multidrug-resistant (MDR) bacteria are shown in many countries as severe widespread health threats. Consequently, attention has been devoted to new nanoparticle-based materials in the field of antimicrobial chemotherapy for burn wound infections. This study aimed to evaluate both and efficacies of nanoparticle-antibiotic combinations as new classes of materials subjected against MDR .

A new trend in the medication of hepatocyte cytoxicity in mice: protective role of probiotic bacteria.

Liver toxicity is affected by several factors, including certain medications, fumes emission from factories, materials used in industries, and exposure to chemicals such as carbon tetrachloride (CCl). Some preselected probiotic bacteria strains have been widely employed in different medical researches due to their antioxidant, anticancer, antimicrobial, anti-inflammatory characters, and hepatoprotective factor. The present study was aimed to evaluate the protective role of probiotic bacteria (Lactobacillus plantarum DSMZ 20174) and their ameliorative effects against CCl-induced hepatotoxicity in mice.

The role of silver nanoparticles biosynthesized by and cyanobacteria for malachite green removal from wastewater.

In this study, biosynthesis of silver nanoparticles (AgNPs) using two species of cyanobacteria, (Kütz) and (Gomont) was investigated and evaluated for dye removing capacity. The formation of AgNPs was detected by the change in colour using UV-Vis spectroscopy and further characterised by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy FTIR). The obtained AgNPs were spherical to oval with average particle size of 17.

Production, Partial Purification, and Biochemical Characterization of a Thermotolerant Alkaline Metallo-protease from Staphylococcus sciuri.

Protease-producing Staphylococcus sciuri was isolated from poultry soil samples and culture conditions for protease production were optimized. The isolated protease showed a maximum activity of 235.1 U/ml.

Biosynthesis of silver nanoparticles by cell-free extracts from some bacteria species for dye removal from wastewater.

Objectives: To investigate the biosynthesis of silver nanoparticles (AgNPs) using extracts of some bacterial isolates Bacillus pumilus, Bacillus paralicheniformis and Sphingomonas paucimobilis. The formation of AgNPs was detected by the change in color into yellow and confirmed by the UV-Vis spectroscopy. The nanoparticles were characterized by X-ray diffraction (XRD), transmission electron microscopy (TEM) and Fourier transform infrared spectroscopy (FTIR).

Protective Efficacy of Against Acute Cadmium Toxicity in Mice.

Cadmium (Cd) is a highly toxic heavy metal, wide occupational and an environmental pollutant, affecting human health. Probiotics especially lactic acid bacteria (LAB) have the capacity to bind, remove and to decrease tissue cadmium levels. The objective was to evaluate the potency of Cd binding capacity, antioxidative properties of probiotic bacteria against cadmium and its probable detoxification effect against Cd-induced toxicity in mice.

Effect of combination therapy between thyme oil and ciprofloxacin on ulcer-forming Shigella flexneri.

Introduction: Shigella flexneri is a Gram-negative bacteria that has the ability to invade the epithelium of the colon and cause colon ulcers.

Methodology: The ability of isolated Shigella flexneri from bloody diarrhea to cause colon ulcers was investigated by histopathological examination via oral administration of the bacteria to adult male albino Sprague-Dawley rats. The antibacterial activity of thyme oil, ciprofloxacin, and their combination were evaluated in vitro and in vivo.

Screening of microbial contamination and antimicrobial activity of sea cucumber Holothuria polii.

Microbiological studies were carried out on microbial contamination and antimicrobial activity of sea cucumber Holothuria polii collected from Mediterranean Sea at Abu-kir shore of Alexandria, Egypt. The obtained results revealed the presence of isolates of five human Gram-negative pathogenic bacteria, representing five genera were identified to species level, including, Esherichia coli, Klebsiella pneumoniae, Pseudomonas aeruginosa, Salmonella sp. and Shigella sp.
