Screening for hepatitis B virus (HBV), hepatitis C virus (HCV) and syphilis infections among asymptomatic students of a private university in Western Delta, Nigeria
This study was aimed at screening for non-treponemal antibodies, anti-hepatitis C and hepatitis B surface antigen markers among asymptomatic students of Western Delta University, Oghara, Nigeria. Venous blood was collected from 318 students of 26 years average age who did not show any visible signs or symptoms of any of the three infections. Blood samples were processed and screened for hepatitis C, hepatitis B and...

Lithium chloride affects mycelial growth of white rot fungi: Fungal screening for Li-enrichment
The enrichment of edible mushrooms with lithium (Li) may be a strategy to provide forms of lithium that are more soluble and bioavailable for humans. Therefore, it is important to determine which species of fungi are able to grow in the presence of Li, and which concentrations of Li allow fungal growth. Twelve white rot fungi strains were grown in potato dextrose agar media, supplemented with 0 to 1.65 g L-1 lithium...

Epidemiological trends in pathogens from the 2012 Thai flooding disaster
Fungi and bacteria in water samples taken from various flooded areas in Narathiwat Province, Thailand, were investigated. They were isolated by filtration from water samples, and identified by examining macroscopic and microscopic features for fungi and using biochemical methods for bacteria. Nine species of filamentous fungi and two yeast species were isolated. Water contaminated with dermatophytes contained...

Phenotypic characterization of phenol degrading microorganisms isolated from olive mill waste
The growth of the olive oil production in Saudi Arabia particularly in Al Jouf region in recent years has been accompanied by an increase in the discharge of associated processing waste. Olive mill waste is produced through the extraction of oil from the olive fruit using the traditional mill and press process. Deterioration of the environment due to olive mill wastes disposal is a serious problem. When olive mill waste...

Assessment of chemical and bacteriological quality of pipe-borne water from various locations in Delta State University, Abraka, Nigeria
Eighteen samples, consisting of six samples each, from three different locations that were 250, 500 and 750 away from the drinking water source in Delta State University, Abraka Campus, were collected and analyzed for their microbial and chemical quality using standard methods. Total viable counts were carried out using the pour plate method, while the most probable number was determined with the multiple tube...

Analysis of the distribution of phytoplankton and enteric bacteria in Efteni Lake, Turkey
Efteni Lake is a small and shallow lake located at the Western Black Sea Region of Turkey that is under severe environmental threat in terms of receiving land-based sources of pollutants especially of diffuse character. No field investigations related to phytoplankton distribution or enteric bacteria in the lake have been conducted prior to this study. To fill this gap in order to better understand the present status of...

Production and characterization of exopolysaccharides (EPS) from mangrove filamentous fungus, Syncephalastrum sp.
In this study, the production and characterization of exopolysaccharide from Syncephalastrum sp. was carried out. This is the ï¬rst report on the production of exopolysaccharides from Syncephalastrum sp. Totally, four different fungi (Aspergillus niger, Aspergillus flavus, Penicillium expansum and Syncephalastrum sp.) were screened for exopolysaccharide production. Among these, maximum polysaccharide producing species...

Efflux pump genes and chlorhexidine resistance: Clue for Klebsiella pneumoniae infections in intensive care units, Egypt
One of the serious and growing challenges for infection control programs worldwide is hospital acquired infections. Klebsiella pneumoniae is considered the second most common cause of hospital-acquired Gram-negative blood stream infections. Chlorhexidine is a topical antiseptic agent, widely used in different applications in hospitals. Healthcare associated infection rates were lower after chlorhexidine-containing...

Production and characterization of alkaliphilic alpha-amylase from Bacillus subtilis A10 isolated from soils of Kahramanmaras, Turkey
Bacillus subtilis A10 isolated from orchard soil, Kahramanmaras, Turkey. The enzyme synthesis was observed between pH 7.0-11.0, with an optimum 37°C. The amylase was purified by fractional ammonium sulfate precipitation and sephadex G-100 column. Analysis of the enzyme with sodium dodecyl sulfate polyacrylamide gel electrophoresis (SDS-PAGE) revealed a single band which was estimated as 46.9 kDa. The enzyme...

Molecular identification and antibiotics resistance genes profile of Pseudomonas aeruginosa isolated from Iraqi patients
Pseudomonas aeruginosa is one of the leading Gram-negative organisms associated with nosocomial infections. The increasing frequency of multidrug-resistant P. aeruginosa (MDRPA) strains affects the efficacious antimicrobial options which are severely limited. In this prospective study, forty two different types of samples collected from patients with multiple types of infections attainted to AL-Kadhyimia Teaching...
