Etiology of apple tree dieback in Tunisia and abiotic factors associated with the disease
An apple tree dieback syndrome causing severe tree losses was observed in the main apple producing regions in Tunisia from 2006-2008. This work aimed at identification of the causal agents and the factors that promote apple tree dieback. The causal agents of the syndrome included the following: Phytophthora and Pythium species: Phytophthora parasitica and Phytophthora inundata, Pythium sp., Pythium indigoferae, Pythium...

Microbial changes in egg white “curd/cottage cheese†during storage
Egg white curd cheese is a curdled protein concentrate made from egg whites. Its advantages are: high protein content, a taste similar to cow's milk curd cheese, minimum carbohydrates, and no fat or cholesterol. Thus, it offers an attractive substitute for cow's milk curd cheese to many followers of a “modern lifestyle” as well as those living with health problems (sensitivity to milk products). Both...

Ecosafe bioremediation of dairy industry effluent using Streptomyces indiaensis ACT 7 and Streptomyces hygroscopicus ACT 14 and application for seed germination of Vigna radiata
Marine actinomycetes strains of Streptomyces indiaensis ACT 7 and Streptomyces hygroscopicus ACT 14 were efficiently utilized for the bioremediation of dairy industry effluent. The effluent characterization before and after the treatment were observed. The maximum reduction of TS, TDS, TSS, biological oxygen demand (BOD), chemical oxygen demand (COD), chloride, oil and fat content were observed for effluent treatment by...

Anti-candidal activity of Piper betle (L.), Vitex negundo (L.) and Jasminum grandiflorum (L.)
The discovery of antimicrobials from traditional medicinal plants is gaining importance. The objectives of this study were to determine the anti-candidal activity of young and mature leaves of Piper betle collected from dry and wet zones of Sri Lanka, leaves and roots of Vitex negundo and leaves of Jasminum grandiflorum and the determination of minimum inhibitory concentrations (MIC). Water and ethanolic extracts of...

Evaluation of antibacterial and antioxidant activity of extracts of eelgrass Zostera marina Linnaeus
Zostera marina L. is one of marine flowering plants, which plays an important role in coastal ecosystems by generating oxygen and organic substance and providing a habitat for other organisms. However, its residues on seashore have caused serious environmental problems in some coasts worldwide. In this paper, crude extract of Z. marina L. was prepared using methanol-water (1:1, v/v) and further separated into petroleum...

Comparative detection of African swine fever virus by loop-mediated isothermal amplification assay and polymerase chain reaction in domestic pigs in Uganda
African swine fever (ASF) is a contagious viral disease, which can cause up to 100% mortality among domestic pigs. Pig production is growing rapidly in Uganda among East African countries and is not only a source of food but also an important income for many people living in the rural areas. Field diagnosis of ASF depends only on clinical signs and has to be confirmed in the laboratory since the clinical signs are not...

Prevalence of asymptomatic hepatitis B virus surface antigenemia in children in Ilesha, Osun state, South-Western Nigeria
Hepatitis B virus (HBV) infection is endemic in sub-Saharan Africa with a range of 8 to 20% prevalence of chronic carriers. Most HBV infections occur early in life by perinatal transmission from the mother to her newborn baby, and horizontal transmission from child to child resulting from blood contact. This study was therefore carried out to assess the prevalence of Hepatitis B virus surface antigenemia (HBsAg) in...
