BACKGROUND Goa is a coastal state in India and salt making is being practiced for many years. This investigation aimed in determining the culturable haloarchaeal diversity during two different phases of salt production in a natural solar saltern of Ribandar, Goa. Water and sediment samples were collected from the saltern during pre-salt harvesting phase and salt harvesting phase. Salinity and p...

Paspalum dilatatum spikelets with ergot symptoms were collected from Rice Research Institute of Iran in Rasht, Guilan province during the fall of 2018. Ergot symptoms usually are caused by different Claviceps species on grasses. Sclerotia of ergot were globular in shape, black in color and irregularly roughened on the surface that resembles a brain. Different fungi were isolat...

Die-back disease caused by Paecilomyces variotti is one of the most destructive diseases of pistachio in Iran. In this study, genetic diversity of Paecilomyces variotti isolates was investigated with SSR marker, using six primers pairs. Sampling was done from pistachio gardens in different geographical zones of Kerman province during summer 2013. Various fungal isolates were isolated from infec...

The genus Pseudomonas is a metabolically versatile group of gram-negative, motile, rod-shaped bacteria. They are common soil-dwelling aerotactic gram-negative proteobacteria with the unique ability to utilize exotic carbon sources for energy. Some members of the genus Pseudomonas are able to metabolize chemical pollutants in the environment, and as a result can be used for bioremediation. There...

abstract: in order to determine genetic variability among 33 isolates of fusarium semitectum, morpho- logical and molecular studies were carried out. isolates from different paddy fields in the north of iran were separated from each other in four morphotype groups. the isolates showed a high level of variation in aerial mycelium, color of colony, number of septa and growth rate on potato dextro...

Anthracnose symptoms were frequently observed on leaves, petioles, and stems of Chinese mallow grown in Namyangju, Korea, during a disease survey performed in November, 2007. The disease incidence was as high as 30% in the 12 greenhouses investigated. A total of 38 isolates of the Colletotrichum species were obtained from the anthracnose symptoms, and all the isolates were identified as Colleto...

Three isolates of Penicillium pimiteouiense were recovered from sandy beach soil samples in Penang Island, Peninsular Malaysia. All the isolates were identified based on morphological characteristics and phylogenetic analysis of internal transcribed spacer regions and β-tubulin gene. This is a first record of P. pimiteouiense in Malaysia.

conclusions this study provides initial data on the prevalence and distribution of the flaa, cadf, ciab, cdtb, cgtb, docc and wlan genes in c. jejuni. background campylobacter jejuni (c. jejuni) is a major cause of human diarrheal disease. objectives this study was conducted to determine the prevalence of different pathogenic genes in isolates recovered from human stool samples in rosario, arge...

Recently, genomic sequencing of a Bacillus thuringiensis (Bt) isolate from our collection revealed the presence of an apparent operon encoding an insecticidal toxin complex (Tca) similar to that first described from the entomopathogen Photorhabdus luminescens. To determine whether these genes are widespread among Bt strains, we screened isolates from the collection for the presence of tccC, one...

Abstract Background Bacillus thuringiensis ( Bt ) produces a group of ?-endotoxin proteins designated as cry toxins. No doubt that isolates are excellent potential candidates for biological control strategies. Results The present study showed 12 strains were isolated and characterized at morphological, biochemical, molecular levels. All the tested gram-positive, endospore-forming, possessing ty...
