The basis of nonhost resistance for future genetic engineering to find out durable resistance in agricultural crops
Plant disease resistance is one of the most desirable traits for agricultural production, especially in the present time of fear over food production and crop security. Disease plays an important role in crop production and quality of products. The one key factor of food security and production is plant disease resistance. Several resistance gene(s) are reported from the same host range to overcome against disease...

Probiotic encapsulation
Encapsulation technologies are used to keep probiotic cell viable throughout storage, commercialization and use in food products, so that these cells are active during their passage through the gastrointestinal tract. This review describes the most common encapsulation technologies and encapsulation materials used for maintaining the viability of probiotic bacteria under adverse external conditions. Illustrations are...

Ecology of pulpal and periapical flora
Inflammatory lesions in the periapical tissues of the teeth are a result of root canal infection following partial or complete breakdown of the pulp. Infected root canals have a complex microbial flora consisting of cocci, rods, spirochaetes, filaments and fungi which may exist as a loose collection in mist canal lumen or as dense aggregates (biofilms) adhered to dentinal walls. The biofilm environment has been found to...

Destruction of Giardia Lamblia by electrical treatment of infected tab water
Protozoan parasites are responsible for the majority of gastrointestinal infections and even drinking treated tap water was reported risk factor for sporadic giardiasis. Variety of technologies has been used for elimination of Giardia cysts as well as removing other microbial contaminants and particles. The cysts are usually identified by their indistinguishable morphology. We applied direct current (DC) electrical...

Comparison of soil microbial communities between high and low yield organically managed orchards
Microbial communities play an important role in soil nutrient cycling. The present study aimed to evaluate the relationships of plant species, soil physical and chemical properties and microbial communities between high- and low-yield organically managed fruit orchards. The BiologTM and phospholipid fatty acids (PLFAs) analysis were used to evaluate soil microbial communities for eight typical organic orchards in...

Gelatinase production, antimicrobial resistance and pheromone response of conjugative plasmids of Enterococcus faecalis isolated from Egypt
Published data concerning correlation between virulence factors and resistance markers is relatively scarce. The aim of this study was to determine the relationship between antibiotic resistance, gelatinase production and pheromone response in the Enterococcus faecalis pathogens isolated from Egypt. Out of the 19 E. faecalis clinical isolates, 5 were able to produce gelatinase enzyme....

Antibacterial properties of Lactobacillus plantarum isolated from fermented mustards against Streptococcus mutans
Antibacterial properties of Lactobacillus strains isolated from traditional fermented mustard were investigated. Among the strains tested, strain B0105 was found to produce bacteriocin-like compounds against Streptococcus mutans BCRC 10793. Strain B0105 was identified as Lactobacillus plantarum by phenotypical and physiological tests as well as16S rDNA identification. The molecular weight...

Research on biological aerated filter with volcanic filler for pretreatment of micro-polluted source water in lower temperature
A pilot-scale research on dealing with micro-polluted source water of 4.2 m3/h by biological aerated filter (BAF) with volcanic filler for pretreatment was carried out. Under the experimental condition of air/water ratio 1:1, and the ammonia nitrogen of raw water 1.57 to 2.72 mg/L, the ammonia nitrogen average removal rate was 95.8%, when water temperature was above 10°C; and the removal rate was still above 70%,...

Comparative clinical study on diagnostic detection of hepatitis E virus between nested polymerase chain reaction (PCR) and serological tests
This study was carried out to evaluate the diagnostic value of nested reverse transcriptase-polymerase chain reaction (RT-PCR) for HEV (hepatitis E virus) RNA detection relative to anti-HEV immunoglobulin G (IgG) and IgM enzyme-linked immunosorbent assays. One hundred and twenty six (126) patients with sporadic acute hepatitis E were included in this study. We focused on the popular genotype I and IV of HEV-positive...

Induction of non protein thiols by chromium in cyanobacteria isolated from polluted areas
Two cyanobacterial strains Synechocystis “AHZ-HB-MK” and “AHZ-HB-P2A” were isolated from tannery effluent form Lahore, Pakistan and their tolerance against K2CrO4was examined. Although growth was completely inhibited at 10 µg mL-1 in AHZ-HB-P2Astrain, cell growth of AHZ-HB-MK strain was observed even at a concentration of 100 µg mL-1. To show...

Antimicrobial screening of crude extracts from the indigenous Ganoderma lucidum mushrooms in Namibia
The indigenous Ganoderma mushroom belongs to the class Basidiomycetous. It has been used in different systems of traditional medication for the treatment of diseases of human beings and animals. It contains various triterpenes, polysaccharides, alkaloids and steroids known to have broad effects pharmacologically and anti-bacterial properties. The indigenous Ganoderma mushroom has been used by locals...

Medical importance of Lactobacillus fermentum lysate as a bioactive agent against some pathogenic Candida and Aspergillus strains
In search of a safe and new biosource for treating fungal infections, the bacterial lysate of probiotic Lactobacillus fermentum was tested for its antifungal activity against Aspergillus niger, Aspergillus flavus and Candida albicans. The antifungal activity of lysate was analyzed by dry weight, disc diffusion and micro broth dilution methods. The growth of A....

Alteration of BHK-21 cells proteome after foot-and-mouth disease virus infection
Foot-and-mouth disease is a highly contagious viral illness of wild and domestic cloven-hoofed animals. The complex relationship of FMDV and with the host cells leads to its replication and spread. BHK-21 cell line is an in vitro model for FMDV infection and is commonly used for viral seed preparation. In order to better understand the molecular basis of this relationship, a proteomics study on baby hamster...
