group b streptococcus (gbs) is one of the most important bacteria in the majority of maternal and neonatal infections, such as chorioamnionitis, endometritis, bacteremia, sepsis and meningitis. during pregnancy, gbs screening is one of the recommended strategies that are recommended by center of disease control (cdc). this study was aimed to determine the rectovaginal colonization prevalence am...

Pseudomonas cepacia colonization of or infection in patients with cystic fibrosis (CF) has been associated with increased morbidity and premature death. However, current data on national incidence may be biased because of interlaboratory differences in the methods of culturing sputa of patients with CF. We conducted three tests to evaluate the proficiency of microbiology laboratories at CF cent...

Microorganisms are believed to create microenvironments leading to reaction products not predictable from equilibrium thermodynamics and to unique biomineral morphologies. Unambiguous evidence for such environments is, however, rare in natural samples. We have used scanning transmission x-ray microscopy and spectromicroscopy at the sub-40-nm scale, coupled with transmission electron microscopy,...

Correctly identifying nearest "neighbors" of a given microorganism is important in industrial and clinical applications where close relationships imply similar treatment. Microbial classification based on similarity of physiological and genetic organism traits (polyphasic similarity) is experimentally difficult and, arguably, subjective. Evolutionary relatedness, inferred from phylogenetic mark...

Sustainable plant production with the integration of eco-friendly agricultural practices, low chemical inputs, minimal deleterious effects on human health and cost methods, is need moment. In this direction, scientific/industrial community, continuously exploring novel reliable methods. Plant growth promoting microbes are proving more promising to achieve sustainable outcomes. present study, in...

effect of different concentrations of ammonium chloride (ncl) and ammonium nitrate (nn)and surfactants such as tween-80, hpcd and rhamnolipids on the bioremediation of pahs and ocps wasinvestigated. the results showed that the best optimum concentration of ncl and nn was 50 g·kg-1, and thepahs degradation rate during 60 days of remediation was enhanced to 64.6% and 62.8% for ncl and nn,respecti...
