Background: Staphylococcus aureus is a facultative anaerobic Gram-positive coccal bacterium which is frequently found as part of the normal flora on the skin and nasal passages. S. aureus can cause a range of illnesses from minor skin infections to life-threatening diseases. The organism is able to developresistance to a wide range of antibiotics. Resistance to antibiotic is one of th...
Background: Traditional dairy products are the main sources for probiotic bacteria. This study aimed to isolate and characterize the potentially probiotic Lactobacillus strains isolated from traditional dairy products in Iran. Methods: Microbial population of each dairy product was enriched and screened for acid- and bile- resistant strains. The isolates were ...
Arthropods living on plants are able to digest plant biomass with the help of microbial flora in their guts. This study considered three arthropods from different niches - termites, pill-bugs and yellow stem-borers - and screened their guts for cellulase producing microbes. Among 42 unique cellulase-producing strains, 50% belonged to Bacillaceae, 26% belonged to Enterobacteriaceae, 17% belonged...
Toxic chemical nature of tannery wastewater makes it difficult to be treated by routine biological treatment processes. Microbes, already present in tannery wastewater can adapt to these conditions and degrade the organics in tannery wastewater. In the present contribution, three bacterial electrogenic strains, tolerant to tannery environment, were isolated from soil contaminated with tannery w...
Exaiptasia is a laboratory sea anemone model system for stony corals. Two clonal strains are commonly used, referred to as H2 and CC7, that originate from two genetically distinct lineages and that differ in their Symbiodinium specificity. However, little is known about their other microbial associations. Here, we examined and compared the taxonomic composition of the bacterial assemblages of t...
Host genotype can influence the composition of the commensal bacterial community in some organisms. Composition, however, is only one parameter describing a microbial community. Here, we test whether a second parameter-abundance of bacteria-is a heritable trait by quantifying the presence of four commensal bacterial strains within 36 gnotobiotic inbred lines of Drosophila melanogaster. We find ...
the aim of this study was to evaluate the ability of 15 serotypes of salmonella to form biofilm on polystyrene, polyvinyl chloride (pvc) and glass surfaces. .initially slime production was assessed on cra agar and hydrophobicity of 20 salmonella strains isolated from poultry and human and two salmonella enterica serovar typhimurium references strains was achieved by microbial adhesion to n-hexa...
EXAMINATION OF NONSTERILE Preparation of Test Strains PRODUCTS: MICROBIAL Use standardized stable suspensions of test strains or prepare as stated below. Seed-lot culture maintenance techENUMERATION TESTS niques (seed-lot systems) are used so that the viable microorganisms used for inoculation are not more than five passages removed from the original master seed-lot. Grow each of the bacterial ...
We report sequencing the genomes of two new Flavobacterium strains isolated from Lake Washington sediment. From genomic contents, versatile lifestyles were predicted but not bona fide methylotrophy. With the availability of their genomic sequences, the new Flavobacterium strains present prospective models for studying microbial communities in lake sediments.
We have now complete genome sequences of several pairs of closely related prokaryotes (conspecific strains or congeneric species). Surprisingly, even strains of the same species can differ by as much as 20% in gene content. Conceptual and methodological approaches for dealing with such diversity are now being developed, and should transform microbial genomics.
