Background: Since a wide spectrum of bacteria are responsible for causing urinary tract infections. To cover the maximum yield of isolates a study was designed in which a combination of media was used for detection of both gram positive and gram-negative bacteria. Materials and Methods: A Combination MacConkey agar, Blood agar and Cystine lactose electrolyte deficient medium were used at one an...

dutch elm disease is one of the most destructive vascular wilt diseases in the world. ophiosatoma ulmi and o. novo-ulmi had been the most important causal agents of the dutch elm disease in the last century. so, in order to manage of disease, their identification and distinction is necessary. these fungal species were distinguished based on morphological, physiological and molecular characters....

71 samples of milk and dairy products were collected from 18 cities throughout iran. 93 strains of lactic acid bacteria (lab) were isolated and assayed against four opportunistic patho gens including e. coli, proteus and klebsiella as gram-negative and s. aureus as a gram-positive organism. all indicators (organisms) were hospital strains. among isolated bacteria, lactobacilli (37 isolates) had...

BACKGROUND: It is a national priority to look for new probiotic bacteria with highly active biological properties create generation of probiotics, ferments, therapeutic, and prophylactic fermented milk products, taking into account ethnocultural regional characteristics. AIM: The aim the study assess strains lactobacilli (antimicrobial adhesive), which are isolated from lactic acid products dif...

  To study the existence of Clostridium septicum as probable agent associated with currently occurrence of black quarter in Urmia area, sheep-dung samples were collected. The bacteriological examinations on suspicious gram positive anaerobic spore-bearing bacilli which are in Clostridia genus include isolation and biochemical identification were performed. The results showed 28 different types ...

Rice blast is not only one of the earliest known plant disease but also one of the most widely distributed, occurring in every region of the world where rice is grown. Ten isolates of Pyricularia oryzae causing rice blast disease were evaluated for their morphological, pathogenic, virulence and genetic characterization using RAPD marker. Isolates were classified into three groups based on patho...

backgrounds and objectives: classified as low pathogenic avian influenza (lpai) viruses, the h9n2 subtype causes severe respiratory disease in poultry farms and occasional respiratory disease in humans. in this study, the neuraminidase (na) gene of three avian influenza (ai) h9n2 strains isolated from poultry farms in iran during 2010-11, as well as other reported iranian h9n2 isolates, were ge...

Corynespora cassiicola threatens soybean and cotton production in Brazil. The objective of this study was to evaluate cultural morphological aspects C. isolated from different Brazilian regions, culture media. isolates were grown PDA (Potato Dextrose Agar) V8 juice agar characteristics evaluated were: color, aspect, growth rate mycelia, as well dimension conidia, number septa per conidium. Cult...

Leaf blight and bulb rot symptoms were observed on narcissus plants grown in Yongin, Cheongwon and Namhae areas in Korea during disease survey from 1999 to 2002. A total of 15 isolates of Botrytis sp. were obtained from the infected plant parts of narcissus. All the isolates were identified as Botrytis narcissicola based on their morphological and cultural characteristics. Three isolates of B. ...

sooty blotch and flyspeck occur on fruit surfaces and result in economic losses due to less attractive appearance. sooty blotch fungi form dark mycelial mats whereas flyspeck fungal agents are well characterized with black, sclerotium-like bodies on fruit surface. whilst more than 60 species have been reported in association with these two fungal diseases, thus far they have not been studied in...
