Population genomic analyses reveal high diversity, recombination and nosocomial transmission among () isolates causing invasive infections.

is a commensal yeast of the gastrointestinal tract and skin of humans. However, it causes opportunistic infections in immunocompromised patients, and is the second most common pathogen causing bloodstream infections. Although there are many studies on the epidemiology of infections, the fine- and large-scale geographical nature of remain incompletely understood.

Genomic Epidemiology of Carbapenem-Resistant in Qatar: Emergence and Dissemination of Hypervirulent Klebsiella pneumoniae Sequence Type 383 Strains.

The emergence of carbapenem-resistant, hypervirulent Klebsiella pneumoniae is a new threat to health care. We studied the molecular epidemiology of carbapenem-resistant Klebsiella pneumoniae isolates in Qatar using whole-genome sequence data. We also characterized the prevalence and genetic basis of hypervirulent phenotypes and established the virulence potential using a Galleria mellonella model.

Efficacy of Leaf Extracts: Volatile Compounds, Antioxidant and Anti-Inflammatory Activity, and Green Synthesis of Potential Antibacterial Silver Nanoparticles.

, widely distributed in Jordan as an ornamental plant, is a synonoum for . Phytochemical studies examining the volatile chemicals in leaves are limited, despite the rising demand for their numerous applications. Furthermore, it was only recently that a report described the friendly synthesis of silver nanoparticles (AgNPs) using aqueous extract derived from leaves.

The first consecutive 5000 patients with Coronavirus Disease 2019 from Qatar; a nation-wide cohort study.

Background: There are limited data on Coronavirus Disease 2019 (COVID-19) outcomes at a national level, and none after 60 days of follow up. The aim of this study was to describe national, 60-day all-cause mortality associated with COVID-19, and to identify risk factors associated with admission to an intensive care unit (ICU).

Methods: This was a retrospective cohort study including the first consecutive 5000 patients with COVID-19 in Qatar who completed 60 days of follow up by June 17, 2020.

Pasta quality as impacted by the type of flour and starch and the level of egg addition.

Unlabelled: This study investigated the effects of substituting wheat flour with fractions of different starch types and egg levels on pasta quality. First order mixture response surface model was used where the effects of various starch types and egg levels on pasta quality were evaluated. Coefficients of estimation were determined and fractional contribution of wheat, starch type and egg levels were evaluated.
