Introduction. Chronic persistent device-related infections (DRIs) often give culture-negative results in a microbiological investigation. In such cases, investigations on the device metagenome might have diagnostic value. Materials and Methods. The 16SrRNA gene sequence analysis next-generation sequencing (NGS) of clinical were performed to detect bacterial diversity invasive medical devices po...

Polar microbiology remains as the most fascinating area of research which mainly focuses on exploration psychrophilic organisms for having their cold-active enzymes biotechnological potential. In this study, we have explored a culturable bacterial community and isolated 27 isolates with different morphology from an unexplored site Arctic region, possibility identifying various active biomolecul...

Cyanobacteria (blur-green algae) are interest member of a group known as eubacteria, they are photosynthetic prokaryotes, that were originally classified as microalgae and distributed worldwide from polar to equatorial latitudes. They have very specialized cells (heterocyst, Akinetes) that are able to fix nitrogen and serve at high temperature or drought. Synthesis of toxin by many cyanobacteri...

BACKGROUND Leptospirosis is caused by pathogenic spirochetes of the genus Leptospira spp. This zoonotic disease is distributed globally and affects domestic animals, including cattle. Leptospira interrogans serogroup Sejroe serovar Hardjo and Leptospira borgpetersenii serogroup Sejroe serovar Hardjo remain important species associated with this reproductive disease in livestock production. Prev...

The microbiome of peri-implantitis sites and healthy dental sites was determined in subjects with a history of periodontitis. Ten systemically healthy non-smokers received periodontal treatment before implant placement. Plaque samples were collected from four sites of one implant with peri-implantitis (bone loss ≥2mm; PPD ≥6mm; BOP/suppuration; >1year loading) and from one dental site per quadr...

L. monocytogenes adherence to food-associated abiotic surfaces and the development of biofilms as one of the underlying reasons for the contamination of ready-to-eat products is well known. The over-expression of internalins that improves adherence has been noted in cells growing as attached cells or at elevated incubation temperatures. However, the role of other internalin-independent surface ...

BACKGROUND Mycoplasma hominis and Ureaplasma urealyticum are important causative agents of vaginitis, cervicitis, postpartum sepsis, reproductive infections and infertility in both males and females. OBJECTIVES According to the uncertain prevalence of U. urealyticum and M. hominis in Iranian infertile females, the present study was carried out to determine the prevalence of U. urealyticum and...

Human cells are known to express many chimeric RNAs, i.e. RNAs containing two genes' sequences. Wondering whether there also is trimeric RNA, i.e. an RNA containing three genes' sequences, we wrote simple computer code to screen human expression sequence tags (ESTs) deposited in different public databases, and obtained hundreds of putative trimeric ESTs. We then used NCBI Blast and UCSC Blat br...

A mixed culture capable of dechlorinating perchloroethylene (PCE) to ethene was analyzed under non steady and pseudo-steady state conditions. Dehalococcoides mccartyi, considered to be the primary dechlorinating bacterium able to completely degrade chlorinated hydrocarbons to non toxic ethene, could be detected by CAtalyzed Reporter Deposition Fluorescence In Situ Hybridization (CARD-FISH) sinc...
