Antagonistic yeasts from a salt-lake region in Egypt: identification of a taxonomically distinct group of phylloplane strains related to Sporisorium.

Non-pathogenic yeasts antagonising microorganisms that cause pre- and postharvest diseases of plants have been found in diverse habitats. Their practical applicability as biocontrol agents (BCAs) depends on the strength of their antagonistic activity and/or spectrum of sensitive target microorganisms. In this study, yeasts were isolated from the phylloplane and fruits of plants growing in the alkaline water lake region Wadi El-Natrun, Egypt, and tested for antifungal and antibacterial activity.

Effect of ultrasound-enhanced seeds oil on wound healing: An animal model.

Objectives: oil, ultrasound, and moist-exposed burn ointment (MEBO) have been suggested as noninvasive treatments for a number of inflammatory conditions and to accelerate wound healing. The aim of this study was to evaluate the efficiency of pulsed and continuous modes of ultrasound either alone or through phonophoresis, with oil, or MEBO ointment in the treatment of chemical burns.

Methods: Thirty-five local rabbits were randomly divided into seven equal groups: pulsed ultrasound, continuous ultrasound, topical oil, pulsed phonophoresis, continuous phonophoresis, topical MEBO ointment, and control group.

Detection and Characterization of Antimicrobial Resistance and Putative Virulence Genes in Aeromonas veronii Biovar Sobria Isolated from Gilthead Sea Bream (Sparus aurata L.).

The purposes of this study were to investigate the antimicrobial resistance of Aeromonas veronii biovar sobria isolated from gilthead sea bream and to characterize the virulence-implicated genes. Fish samples (n=365) were collected from wholesale and retail markets in Aljouf, Saudi Arabia between 2013 and 2014. A total of 45 A.

Chemical composition, antimicrobial and antibiofilm activity of the essential oil and methanol extract of the Mediterranean cypress (Cupressus sempervirens L.).

Background: Cupressus sempervirens is a medicinal plant traditional, its dried leaves are used in treatment of stomach pain, diabetes, inflammation, toothache, laryngitis and as contraceptive.

Methods: The present study was conducted to evaluate the in vitro antimicrobial, antibiofilm and determination chemical contents of the essential oil (Eo) and methanol extract from Mediterranean C. sempervirens L.

Adaptation to tert-butyl hydroperoxide at a plasma membrane level in the fission yeast Schizosaccharomyces pombe parental strain and its t-BuOOH-resistant mutant.

The one-gene mutant hyd1-190 of the fission yeast Schizosaccharomyces pombe displayed four-fold resistance to tert-butyl hydroperoxide (t-BuOOH) in comparison with its parental strain hyd(+). The cells of hyd1-190 exhibited a quantitative alteration in the sterol content and hence in the fatty acid composition of the plasma membrane, reflected in a two-fold amphotericin B sensitivity, increased rigidity of the plasma membrane, revealed by an elevated (Δ7.9 °C) phase-transition temperature, measured by means of electron paramagnetic resonance spectroscopy, and a significantly decreased uptake of glycerol.

Viral and bacterial infections associated with camel (Camelus dromedarius) calf diarrhea in North Province, Saudi Arabia.

Diarrhea and deaths in new-born camel calves were noticed by veterinary investigators and pastoralist in Saudi Arabia to be very high. Hence, it is thought to be necessary to investigate this problem from the virological and bacteriological point of view. The role of pathogenic bacteria and viruses in six different towns of North Province (Al-Assafia, Arar, Domat Aljandal, Hail, Skaka and Khoa) in Saudi Arabia was studied.

Novel thermostable and alkalitolerant amylase production by Geobacillus stearothermophilus HP 3.

This study reports the production and characterisation of a novel thermostable alkaline amylase from the newly isolated Geobacillus stearothermophilus HP 3. The optimum temperature and pH for enzyme production was 55°C and 9.0, respectively.

Effective of metronidazole to bacterial flora in vagina and the impact of microbes on live birth rate during intracytoplasmic sperm injection (ICSI).

Purpose: The aim of this study was to investigate the impact of bacterial vaginal flora on life-birth rate during ICSI and influence of metronidazole as antibiotic treatment course before ICSI.

Method: We enrolled 71 women who were undergoing ICSI. At embryo transfer (ET), all of the women had quantitative vaginal culture, ET catheter-tip culture, and vaginal Gram stain scored for bacterial vaginosis.
