–Phosphorus is one of the most vital macronutrients required for the growth and development of plants. A large number of microorganisms present in the rhizosphere are known to solubilize and make available the insoluble phosphorus in the available form to the plants. A total of fifty phosphate solublizing bacterial colonies were isolated on the Pikovskaya’s (PKV) agar medium, containing insolub...

We investigated the prevalence of seed borne fungal pathogens in rice variety BRRI Dhan46 and to evaluate the efficacy of antagonistic bacteria in controlling seed borne disease. A composite sample of BRRI Dhan46 was assayed. Five seed borne fungi viz. Fusarium sp., Bipolaris oryzae, Curvularia sp., Gliocladium sp. and Aspergillus flavus were isolated from the rice seeds. Fifteen probable antag...

Fourteen thermotolerant and thermophilic bacterial isolates from a hot spring in Guanajuato State, Mexico, were tested for their ability to induce the corrosion of carbon steel in monocultures and, in selected cases, in mixed cultures and co-culture with a sulfate-reducing strain, SRB-M. Characterization by 16S rDNA showed that three of the thermophilic isolates (G9a, G9c, and G11) belong to th...

PURPOSE To determine the distribution of invasive and cytotoxic genotypes among ocular isolates of P. aeruginosa and investigate the influence of the type III secretion system (T3SS) on adhesion to conventional, cosmetic, and silicone hydrogel contact lenses (CL). METHODS Clinical isolates from 2001 to 2010 were analyzed by multiplex PCR for exoS, exoU, and exoT genes. Bacterial adhesion to e...

This study aimed to evaluate the biocontrol potential of bacteria isolated from different plant species and soils. The production of compounds related to phytopathogen biocontrol and/or promotion of plant growth in bacterial isolates was evaluated by measuring the production of antimicrobial compounds (ammonia and antibiosis) and hydrolytic enzymes (amylases, lipases, proteases, and chitinases)...

Background and Objective: In the current study, the relevance of the respiratory infection with the age, sex, and seasonal variation of the year were studied side by side with the determination of the responsible bacterial pathogen and their antibiotic sensitivity patterns. Materials and Methods: One hundred sputum samples were collected to determine the causative bacteria of respiratory distr...

Background and Objective. Antimicrobial resistance is now a major challenge to clinicians for treating patients. Hence, this short term study was undertaken to detect the incidence of multidrug-resistant (MDR), extensively drug-resistant (XDR), and pandrug-resistant (PDR) bacterial isolates in a tertiary care hospital. Material and Methods. The clinical samples were cultured and bacterial strai...

Background and Objectives Staphylococcus epidermidis produces biofilm by extracellular polysaccharides, causing bacterial adherence to different surfaces. Anti-microbial effects of nickel nanoparticles on some bacterial strains such as S. aureus and Escherichia coli have been determined in limited studies. The aim of the present study is to examine the inhibitory effect of nickel nanoparticles ...

The potential of different bacterial-feeding Rhabditida to consume isolates of Burkholderia cepacia with known agricultural biocontrol ability was examined. Caenorhabditis elegans, Diploscapter sp., Oscheius myriophila, Pelodera strongyloides, Pristionchus pacificus, Zeldia punctata, Panagrellus redivivus, and Distolabrellus veechi were tested for growth on and preference for Escherichia coli O...

Pioneer plants are with high adaptability, so they can grow in disturbed environments, such as ex-limestone mining areas. This adaptability is supported by the ability of these to associate soil bacteria their rhizosphere area. The presence support growth pioneer on land. purpose this study was characterize around former limestone Soil samples area 5 from ex-mining lime were then isolated using...
