Methicillin-resistant and methicillin-susceptible Staphylococcus aureus in allergic rhinitis patient and healthy individuals: Prevalence, antibiotic susceptibility and effect on disease severity
Allergic rhinitis is a common condition affecting populations globally. It has been recently suggested to increase the risk of both methicillin resistant and susceptible Staphylococcus aureus (MRSA, MSSA) nasal carriage. The aim of this study was to assess the prevalence and antibiogram to MSSA and MRSA among allergic rhinitis patients and healthy individuals, and its effect on disease severity. Nasal swabs were...

Antimicrobial and phytochemical screening of Olea europaea Linn. extracts against dental pathogens
Dental caries is a common disease in human population which has a multifactorial etiology. The present study aimed to investigate the antimicrobial efficacy of various extracts of Olea europaea against six bacterial pathogens [Staphylococcus aureus, Streptococcus mutans, Staphylococcus sanguinis, Staphylococcus sobrinus, Staphylococcus salivarius, Lactobacillus acidophilus and one fungi (Candida albicans)]. Plant...

16s rDNA sequence characterization and homogeneity of halophilic Bacillus sp. isolated from athalosaline lake (Al Jouf, Saudi Arabia)
Moderate halophilic bacteria from Dowma al Jandal in extreme north Al Jouf were isolated using cultural-dependent methods. Halophiles from hypersaline environments possess a biotechnological potential. Polymerase chain reaction (PCR) amplification of the 16s rRNA gene and phylogentic analysis were used to identify strains. Culturing was done aerobically in chemically defined media (CDM). Salt concentration (15%) was...

Microbial and physico-chemical changes in tomato juice subjected to pulsed electric field treatment
The possibility of microbial reduction by external pulsed electric field (PEF) offers a new application for pulsed power technology. Applying PEF technology to food pasteurization is a promising non-thermal method. One of such application is prevention of microbial growth, an effect that is based on irrreversible permiabilization of cell membranes. The objective of this study was to increase the shelf life of tomato...

Antimicrobial profile of multidrug-resistant Staphylococcus spp. isolated from bovine mastitis cases in the northwest region of Paraná State, Brazil
Bovine mastitis is the main cause of economic losses in dairy industry. The aim of this study was to determine the prevalence and antibiotic-resistance profile of Staphylococcus aureus and coagulase-negative Staphylococcus spp. isolated from bovine mastitis cases in the municipality of Altônia, northwest region of Paraná State, Brazil. Two hundred and forty-eight dairy cows were examined for the presence of...

Diversity of yeasts in otchè, a traditional starter used in fermentation of an opaque sorghum beer “chakpaloâ€
Sorghum beer is a significant diet component of millions of poor rural communities in sub-Saharan Africa. In this study, we identified and biochemically characterized yeast strains isolated from otchè, a traditional starter used in fermentation of chakpalo, an opaque sorghum beer in Benin. 12 samples of otchè were collected from 12 different commercial processing sites. The mean values of pH, titratable...

Evaluation of plant extract in control of dry bubble disease of white button mushroom caused by Verticillium fungicola f.sp. fungicola Preuss (Hassebr)
Dry bubble disease induced by Verticillium fungicola has been observed as an important disease of white button mushroom (Agaricus bisporus) in India. The symptoms produced on differentiated fruit body are localized light brown depressed spots. The adjacent spots coalesce together and form irregular blotches. If the pathogen infection is established before differentiation, sclerodermoid fruiting bodies appear on casing...

Comparative evaluation of antimicrobial properties and phytochemical composition of Artocarpus altilis leaves using ethanol, n-hexane and water
This study was undertaken to describe the comparative evaluation of phytochemical constituents and antimicrobial activity of Artocarpus altilis leaves in three different solvents (ethanol, n-hexane and water). Qualitative and quantitative phytochemical analysis carried out confirmed the presence of alkaloids, tannins, flavonoids, steroids, reducing sugar, saponins, soluble carbohydrate, hydrogen cyanide and glycoside in...

Morphological, physiological and pathogenic variability of small-spore Alternaria sp. causing leaf blight of Solanaceous plants in Algeria
Due to premature defoliation, early blight epidemics can cause major yield losses. Large-spore Alternaria species such as A. solani and A. tomatophila have long been recognized as important pathogens responsible for such blight disease in the family Solanaceae and thus represent a serious risk for crop production. Small-spore Alternaria species have also been frequently isolated from plant samples with typical blight...
