Introduction Aeromonads of medical importance have been reported from numerous clinical, food, and water sources, but identification of genospecies and virulence factors of Aeromonas species from countries in North Africa and the Middle East are few. Methods In total 99 Aeromonas species isolates from different sources (diarrheal children [n=23], non-diarrheal children [n=16], untreated drinkin...

The purpose of this study was to identify the genes coding for resistance to ceftazidime and imipenem and describe the molecular epidemiology of A. baumannii strains isolated from a clinical center in Colombia. Twenty isolates of imipenem-resistant A. baumannii from an equal number of patients with nosocomial infections were obtained. Primers were used to amplify genes bla IMP, bla VIM, bla OXA...

AIM To develop a method for conducting pulsed-field gel electrophoresis (PFGE) on Flavobacterium columnare, to use PFGE to characterize F. columnare channel catfish isolates, and to determine whether variation in pathogenic potential exists in F. columnare isolates from channel catfish. METHODS AND RESULTS On the basis of PFGE-derived profiles, similarity dendrograms constructed for more than...

Francisella tularensis, the etiologic agent of tularemia and a Class A Select Agent, is divided into three subspecies and multiple subpopulations that differ in virulence and geographic distribution. Given these differences, there is a need to rapidly and accurately determine if a strain is F. tularensis and, if it is, assign it to subspecies and subpopulation. We designed TaqMan real-time PCR ...

The aim of the study was a laboratory evaluation antifungal effect leaf extracts from yarrow (Achillea millefolium L.), tansy (Tanacetum vulgare sage (Salvia officinalis L.) and wormwood (Artemisia absinthium on fungi genus Fusarium, major cereal pathogens. used 5%, 10%, 20% concentrations plant extracts, evaluating their linear growth Fusarium avenaceum, F. culmorum, graminearum, sporotrichioi...

In this study, we investigated the rate of colonization of skin of children with atopic dermatitis (AD) by methicillin-resistant Staphylococcus aureus (MRSA) and characterized the isolates. Active skin lesions in pediatric AD patients were cultured with Rodac Staph (Komed, Korea). S. aureus isolates were examined for drug susceptibilities, analyzed for the eta, etb, tst, and pvl genes, and type...

Alternaria solani Sorauer (Ellis), a foliar pathogen of potato (Solanum tuberosum L.), was considered to be difficult to control, responsible for yield losses of up to 30% (24), until the registration of the first strobilurin fungicide, azoxystrobin (Quadris; Syngenta Crop Protection, Greensboro, NC), in 1999. Strobilurins belong to the group of chemicals classified as Quinone outside inhibitor...

One hundred isolates of Fusarium solani species complex were isolated and identified from 58 agricultural soil samples collected from different geographical regions in Kermanshah, Hamadan and Kurdistan provinces of Iran. Based on morphological characteristics, Fusarium falciforme, F. petroliphilum, F. keratoplasticum and F. pseudensiforme, are reported for the first time from Iran.

to determine the role of fusarium species associated with sugar beet root  and crown rot, diseased samples were collected  from different fields of sugar beet in iran including khorasan, khuzestan west azarbayejan, qazvin, tehran, kermanshah ,kerman,lorestan ,hamedan,charmahal va bachtiary provinces during growing seasons 1999-2002. in total, 94 isolates of fusarium were obtained. based on morp...

ABSTRACT Fusarium oxysporum f. sp. lactucae, causal agent of Fusarium wilt of lettuce, is a serious pathogen recently reported in Arizona. Sequence analysis of the mitochondrial small subunit (mtSSU), translation elongation factor 1-alpha (EF-1alpha) gene, and the nuclear ribosomal DNA intergenic spacer (IGS) region was conducted to resolve relationships among f. sp. lactucae isolates, F. oxysp...
