some yeast species play important roles in biological control of some fruits’ post harvest infections. for instant, candida, rhodotorula and pichia species employed in biological control of such post harvest diseases as blue mold (penicillium expansum), and also grey mold (botrytis mali) in apple. species identification of yeasts is some most essential part of the related research activities. d...

fusarium species are cosmopolitan species that frequently isolated from soils and plantdebris and can seriously damaged plant, animal and human. persian gulf beaches in iranare the ideal habitat for a variety of fusarium species. therefore, the study is conductedto gather some information on the population of fusarium species which could be foundin persian gulf beaches in iran. the study involv...

Ticks are important acarina that infest animals. They are obligatory blood sucker arthropods which economically impact cattle industry by reducing weight gain and production. Moreover, they are important vectors of viral, bacterial, rickettsial and parasitic pathogens infecting humans and animals. In view of the importance of Hyalomma anatolicum anatolicum in pathogen transmission, including Th...

Pythium species are cosmopolitan, fungus-like oomycotes which may cause diseases in plants, animals and even human beings. Some of the species, however, are saprophytes and also well-proven biological control agents of plant pathogenic fungi. Since 1968, when the first Pythium species was reported from Iran, ca 44 species, two varieties, and five groups of this genus have been reported from dif...

a survey on the megachilid bees (hymenoptera: megachilidae) fauna of northern iran, between 2010 and 2011, led to the identification of eleven species of the genus coelioxys latreille belonging to subgenera allocoelioxys (6 species), boreocoelioxys (2 species), coelioxys (2 species) and liothyrapis (1 species). of these, six species and one subgenus (liothyrapis) are new to the fauna of iran. d...

In the present study the freshwater algae of Siahdarvishan River were sampled on a montly basis from December 2007 through November 2008. Three sampling stations (Gaght roudkhan , Shahkezr dame and Talab laleh ) were chosen in the river. Some physical and chemical parameters (water temperature , total hardness , nitrate , nitrite, phosphate and pH) of water samples were measured. A to...

 Abstract Background: The disk diffusion method for identification of yeasts species was performed based on different but distinct susceptibilities of yeasts spp. to chemicals: janus green, ethidium bromide, 2,3,5-triphenyltetrazolium chloride, brilliant green, cycloheximide and rhodamine 6G. Methods: Atotal of 568 Iranian soldiers went under study for isolation and identification of Yeast spec...
