melon and musk melon are grown widely in warm and moderate climate regions of the world as well as iran. these crops are attacked by several fungal pathogens including macrophomina phaseolina which causes charcoal rot disease at different growth stages and reduces the yield remarkably. fungicide application and other control methods have not been successful in control of charcoal rot and utiliz...

Paecilomyces variotii is one of the most important causal agents of dieback disease in pistachio (Pistacia vera) gardens. The disease affects different parts of the tree, such as branch and trunk. Assessment of genetic structure in different populations of this species will lead to more useful management of pistachio dieback disease. In this study, genetic variation within samples of P. varioti...

Trichoderma species are among important antagonists of plant pathogenic fungi. The main purpose of this study was to evaluate the biocontrol potential of native Trichoderma spp. isolates from sugar beet fields against Phytophthora drechsleri and P. cryptogea, the causal agents of Phytophthora root rot of sugar beet. During 2007–08, 85 isolates of Trichoderma spp. from sugar beet fields in eight...

objective(s): pseudomonas aeruginosa is a nosocomial pathogen resistant to most antimicrobial treatments. furthermore, it persists in adverse environments thereby forming biofilms on various surfaces. researchers have therefore focused on antibiofilm strategies using nanoparticles due to their unique physicochemical properties. superparamagnetic iron oxide nanoparticles (sionps) have recently s...

We have developed idiotype-anti-idiotype monoclonal antibodies that provide evidence for rabies virus binding to the acetylcholine receptor (AChR). Hybridoma cell lines 7.12 and 7.25 resulted after fusion of NS-1 myeloma cells with spleen cells from a BALB/c mouse immunized with rabies virus strain CVS. Antibody 7.12 reacted with viral glycoprotein and neutralized virus infectivity in vivo. It ...

  Two hundred fifty seven bacterial isolates were collected from colza root and rhizosphere in Golestan, Mazandaran, Guilan and Tehran provinces. Antagonistic effect of bacterial isolates on Rhizoctonia solani, the causal agent of colza damping off, was studied using dual culture method. The results showed that, 60 isolates had the ability to inhibit the growth of R. solani on PDA medium. On th...

The promotion of proper infant feeding practices and the improvement of environmental sanitation have been two important strategies in the effort to reduce diarrhoeal morbidity among infants. Breast-feeding protects infants by decreasing their exposure to water- and foodborne pathogens and by improving their resistance to infection; good sanitation isolates faecal material from the human enviro...
