Objective: Fusarium diseases that cause grain mold and stalk rot of millet are the most important diseases, of these crops in Iran. Fusarium can cause stalk rots, ear rots, and grain mold, resulting in serious production losses in millet, and produce mycotoxins that are harmful to both humans and domesticated animals.  Methods: A total of 23 Fusarium isolates were rec...

Acipenser stellatus is one of the most invaluable species of Sturgeon fishes in the world. The purpose of this study was to identify the resident microbial community from the gastrointestinal tract (GIT) of Acipenser stellatus. One hundred and twenty three fungi were isolated from the GIT of 7 Acipenser stellatus samples including Aspergillus spp (45.5%), Trichoderma spp (8.9%) and Cladophialop...

The purpose of this study was to survey infections with Salmonella spp. in poultry flocks in the vicinity of Tehran and to determine the most frequent serogroups and serotypes implicated. Twenty-eight samples of pullet, layer, and broiler flocks were randomly collected (n=1463), including freshly dropped feces from live birds or visceral organs from dead birds. In most flocks, 60 samples were t...

Field surveys to collect isolates of Bean pod mottle virus (BPMV), a member of the genus Comovirus, were done in 1997, 1998 and 2001 in research centers and growers’ commercial fields in Virginia. The isolates were collected by taking leaves from symptomatic plants and confirming the presence of virus using leaf blot immunoassay, followed by propagation of selected positive samples in the green...

Black sigatoka, caused by the fungus Mycosphaerella fijiensis (anamorphic stage: Paracercospora fijiensis), was first detected in Brazil in early 1998 in the Benjamin Constant and Tabatinga municipalities in the State of Amazonas, near to where the borders of Brazil, Colombia, and Peru converge. Understanding how cultivars react to the pathogen, and characterizing the genetic variability of iso...
