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 ...

Plant associated rhizobacteria prevailing in different agro-ecosystems exhibit multiple traits which could be utilized in various aspect of sustainable agriculture. Two hundred thirty four isolates were obtained from the roots of basmati-385 and basmati super rice varieties growing in clay loam and saline soil at different locations of Punjab (Pakistan). Out of 234 isolates, 27 were able to sol...

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...

background and objectives: acinetobacter spp. are important causes of nosocomial infections. they possess various antibiotic resistance mechanisms including extended spectrum beta lactamases (esbls). the aim of this study was to determine antibiotic resistance profile of acinetobacter clinical isolates especially among esbl-producing strains and to investigate the antimicrobial effects of oleo-...

Fusarium graminearum species complex (FGSC) causes Fusarium head blight in small grain cereals. To date, four species (F. graminearum, F. asiaticum, F. boothii, and F. meridionale ) belonging to FGSC frequently occur in Korean cereals. In addition, we first reported the occurrence of additional species (F. vorosii ) within FGSC, which was isolated from barley, corn, and rice in Korea. Phylogene...

Avian pneumovirus (APV) was first isolated from turkeys in the west-central US following emergence of turkey rhinotracheitis (TRT) during 1996. Subsequently, several APV isolates were obtained from the north-central US. Matrix (M) and fusion (F) protein genes of these isolates were examined for sequence heterogeneity and compared with European APV subtypes A and B. Among US isolates the M gene ...

A polymerase chain reaction (PCR) based diagnostic assay was used to develop markers for detection of Fusarium verticillioides (=F. moniliforme), a fumonisin producing fungus in maize tissues. Species-specific primers were designed based on sequence data from the polyketide synthase (PKS) gene (FUM1- previously FUM5) responsible for fumonisin production in fungi. Four sets of oligonucleotide pr...
