Identification of Rhizobium and Bradyrhizobium strains and especially of indigenous isolates continues to be one of the major difficulties associated with competition studies. Because there is no universally accepted method, the method of choice depends on preference, experience, and equipment. Here, an agar plate technique was used to distinguish strains and field isolates of Rhizobium legumin...

background: chemical control method using different acaricides as spray, dipping solution or pour-on is routinely used for controlling ticks. biological control agents are favorable due to their safety for animals and environment. entomopathogenic fungi such as beauveria bassiana are well known for controlling ticks. in this study, two iranian indigenous strains of b. bassiana ( b. bassiana 519...

AIMS To differentiate nine industrial wine strains of Saccharomyces cerevisiae using microsatellite (simple sequence repeats, SSR) markers. METHODS AND RESULTS Six of the strains were indigenous yeasts currently used as high-density starter monocultures by the Uruguayan wine industry. Unequivocal differentiation of these six native strains and three commercial S. cerevisiae wine strains was a...

Northeastern Atlantic minke whales (Balaenoptera acutorostrata) have a multichambered stomach system which includes a nonglandular forestomach resembling that of ruminants. Bacteria from the forestomachs of herring-eating whales were enumerated and isolated in an anaerobic rumen-like culture medium (M8W medium). The total viable population of anaerobic bacteria ranged from 73 x 10 to 145 x 10/m...

Curing of the hydrogenase-specifying megaplasmid pHG indigenous to strains of the facultative lithoautotrophic bacterium Alcaligenes eutrophus was correlated with a loss of denitrifying ability (Nitd). The retransfer of plasmid pHG1 reconstituted the Nitd phenotype. Plasmid-free mutants were still capable of converting some nitrate to nitrite, but they did not metabolize nitrite under anaerobic...

Lactobacillus salivarius is part of the vertebrate indigenous microbiota of the gastrointestinal tract, oral cavity, and milk. The properties associated with some L. salivarius strains have led to their use as probiotics. Here we describe the draft genome of the pig isolate L. salivarius cp400, providing insights into host-niche specialization.

An indigenous Neisseria gonorrhoeae conjugative plasmid, pLE2450, was tested for its ability to mediate chromosomal gene transfer between gonococcal strains. Plasmid-mediated chromosomal transfer was detected at a low frequency and can be used to establish certain linkage relationships between amino acid and antibiotic resistance markers.

BACKGROUND In recent decades many indigenous communities, policy makers and researchers worldwide have criticized the academic community for not being aware of the specific challenges these communities have faced and still are facing with regard to research. One result of the decades of discourse in indigenous communities is the development in many Western countries of indigenously sensitive et...

Indigenous people throughout the world suffer a higher burden of disease than their non-indigenous counterparts contributing to disproportionate rates of disability. A significant proportion of this disability can be attributed to the adverse effects of smoking. In this paper, we aimed to identify and discuss the key elements of individual-level smoking cessation interventions in indigenous peo...

For long time mushrooms presented interest for consumption as food, as traditional medicine or in bioremediation, due to their nutritional, antioxidant, antimicrobial and therapeutic values. The valorisation of indigenous species of mushrooms both for research or practical applications is a goal for researchers all over the world and requires well characterized collections. Despite the importan...
