Does SEN virus (SENV) infection affect the progression of chronic hepatitis C or B among Egyptian patients?
The effect of SENV infection on chronic viral hepatitis is not very clear till now. Information regarding SENV infections in the Egyptian population where hepatitis viruses are prevalent is limited to a certain extent. We aimed to determine the frequency of SENV and its genotypes H and D in Egyptian patients with chronic hepatitis B (CHB) or C (CHC) and to study its possible role in the progression of liver...

Additive antibacterial activity of naringenin and antibiotic combinations against multidrug resistant Staphylococcus aureus
Methicillin-resistant Staphylococcus aureus has been causing numerous problems in the health care sector. This is mainly due to its ability to develop resistance to a number of antibiotics used to treat staphylococcal infections. Medicinal plants have been used to treat various ailments over the years and are generating a lot of interest as alternative treatment options. Naringenin is a plant derived flavonoid that...

Effect of rock phosphate enriched compost and chemical fertilizers on microbial biomass phosphorus and phosphorus fractions
The aim of this research work was to prepare rock phosphate enriched compost using low-grade mineral such as rock phosphate (RP) mixed with rice straw and Aspergillus awamori and to study their effect on microbial biomass phosphorus (MBP), phosphatase activity and phosphorus (P) fractions in a wheat-soybean cropping system. The experiment was carried out in a randomized block design with four treatments namely, control,...

Antimicrobial activity of volatile organic compounds and their effect on lipid peroxidation and electrolyte loss in Colletotrichum gloeosporioides and Colletotrichum acutatum mycelia
Anthracnose is an important plant disease and is the main disease affecting guava (Psidium guajava) post-harvest, leading to economic losses and limiting fruit export. Because of the indiscriminate use of fungicides, along with environmental and food safety concerns, alternative methods of disease control are warranted. The yeast Saccharomyces cerevisiae produces a mixture of volatile organic compounds (VOCs) that show...

Identification of a chitinase from Apocheima cinerarius nucleopolyhedrovirus
Baculoviruses are important biological control agents against insect pests. In this work, a chitinase from Apocheima cinerarius nucleopolyhedrovirus (ApciNPV) as a fusion protein was highly over-expressed in Escherichia coli M 15 strain and affinity purified on Ni Sepharose 6 Fast Flow column. The modeling structure of ApciNPV chitinase indicated the protein contains a polycystic kidney 1(PKD1) domain on N-terminal and...

Genetic studies on common rust (Puccinia sorghii) of maize under Kashmir conditions
Common rust caused by fungus Puccinia sorghii is among one of the worldwide spread foliar corn diseases. The disease has persisted with varying degrees of susceptibility on higher altitudes in Kashmir valley. Disease reaction studies against common rust were carried out in two crosses involving indigenously identified cytosterile source viz.,15C (A) x I-318 (R) and I-401(A) x I-318(R) for all the six basic generations...

Oral microflora of supragingival and subgingival biofilms in Algerian healthy adults
The purpose of this investigation was to define the cultivable oral microflora in supragingival and subgingival plaques of Algerian healthy adults. Supragingival and subgingival plaque samples were collected from 65 Algerian caries-free, periodontally healthy subjects. Samples were taken from approximal surfaces and analysed for bacterial content after being inoculated on non-selective and selective media and incubated...
