Eleven uncommon yeast species that are associated with high mortality rates irrespective of antifungal therapy were isolated from 17/187 (201 episodes) pediatric and elderly patients fungemia Qatar. The samples taken over a 6-year period (January 2004–December 2010). Isolated included Kluyveromyces marxianus, Lodderomyces elongisporus, Lindnera fabianii, Candida dubliniensis, Meyerozyma guilliermondii, intermedia, Pichia kudriavzevii, Yarrowia lipolytica, Clavispora lusitaniae, pararugosa,...
Resistance to last-line polymyxins mediated by the plasmid-borne mobile colistin resistance gene (mcr-1) represents a new threat global human health. Here we present complete genome sequence of an mcr-1-positive multidrug-resistant Escherichia coli strain (MS8345). We show that MS8345 belongs serotype O2:K1:H4, has large 241,164-bp IncHI2 plasmid carries 15 other antibiotic genes (including extended-spectrum β-lactamase blaCTX-M-1) and 3 putative multidrug efflux systems, contains 14...
The emergence of extended-spectrum beta-lactamase (ESBL)-producing isolates has important clinical and therapeutic implications. High prevalence ESBL-producing Enterobacteriaceae been reported in the literature for samples from a variety infection sites. present study was undertaken to evaluate Enterobacteriaceae, perform molecular characterization antimicrobial susceptibility testing patients admitted intensive care units at Hamad Medical Corporation, Doha, Qatar, November 2012 October...
Campylobacter infections are a major cause of diarrhoea world-wide and two the antimicrobials used for their control (erythromycin ciprofloxacin) have been losing efficacy in recent years. In sample 174 genotyped isolates from stools patients with severe Qatar, collected between 2005 2012, 63.2% showed resistance to ciprofloxacin, 8.6% erythromycin, 0.57% chloramphenicol all were sensitive gentamycin. While 33.9% four antimicrobials, 59.8% resistant at least one, 6.3% none three...
Abstract Background The β-lactam antibiotics have traditionally been the main treatment of Enterobacteriaceae infections, nonetheless, emergence species producing β- Lactamases has rendered this class largely ineffective. There are no published data on etiology urinary tract infections (UTI) and antimicrobial resistance profile uropathogens among children in Qatar. aim study is to determine phenotypic genotypic profiles resistant with UTI Methods Bacteria were isolated from 727 urine...
Brucellosis is one of the most common zoonotic disease affecting humans and animals endemic in many parts world including Gulf Cooperation Council region (GCC).

All isolates were identified as B. melitensis. susceptible doxycycline, tetracycline, streptomycin, gentamicin, trimethoprim / sulfamethoxazole ciprofloxacin...
Abstract One hundred forty-nine carbapenem-resistant Enterobacterales from clinical samples obtained between April 2014 and November 2017 were subjected to whole genome sequencing multi-locus sequence typing. Klebsiella pneumoniae (81, 54.4%) Escherichia coli (38, 25.5%) the most common species. Genes encoding metallo-β-lactamases detected in 68 (45.8%) isolates, OXA-48-like enzymes 60 (40.3%). bla NDM-1 (45; 30.2%) OXA-48 (29; 19.5%) frequent. KPC-encoding genes identified 5 (3.6%)...
Background and Objectives . Bacterial meningitis is a common medical condition in Qatar. The aim of this study was to describe the clinical characteristics bacterial meningitis, frequency each pathogen, its sensitivity antibiotics risk factors for death. Patients Methods This retrospective conducted at Hamad General Hospital between January 1, 2009, December 31, 2013. Results We identified 117 episodes acute 110 patients. Their mean age was<mml:math...
Travel and migration from developing regions, where tropical diseases are common, to more developed industrialised nations can contribute the introduction subsequent spread of infections. With its rapidly expanding economy, Qatar has attracted vast numbers immigrant workers in last two decades, often countries with poor socio-economic levels. Many used arrive patent intestinal parasitic We analysed prevalence helminth infections a dataset 29,286 records subjects referred for stool...
Introduction: This study was conducted at Hamad General Hospital to determine the incidence of fungal peritonitis and describe its clinical microbiological findings in patients undergoing continuous ambulatory peritoneal dialysis Qatar. Methodology: The medical records these between 1 January 2005 31 December 2008 were retrospectively reviewed collected data analysed. Results: During period, 141 episodes observed among 294 patients. In 14 (9.9%), reported with a rate 0.05 per patient year,...
BACKGROUND: Nocardia species are rare, opportunistic organisms that cause disease in both immunocompetent and immunocompromised individuals. OBJECTIVE: To investigate the clinical presentations of various infections based on 16S ribosomal RNA gene isolate, as well related risk factors susceptibility patterns to antimicrobial agents METHODS: Thirteen patients with a diagnosis nocardiosis were included present study. Seven identified by RNA. Susceptibility testing was performed using six...
To describe the clinical presentation, underlying diseases, antimicrobial susceptibility, treatment and outcome of Klebsiella pneumoniae meningitis patients. This retrospective study involved all patients with 15 years age or older who admitted to Hamad General Hospital culture proven from January 1, 2007 December 31, 2012. A total ten cases were identified (nine males one female). Their mean was (43.3±12.8) years. Eight (80%) had nosocomial neurosurgery being most frequent associated...
We report four cases of nosocomial E. coli meningitis, in male patients with accidental and neurosurgical trauma. The interval between accidents/neurosurgical procedures the onset meningitis was 2-15 days (mean 6.25 days). most consistent clinical features were fever deterioration consciousness level. Emergence extended spectrum beta lactamase strains had been observed two (50%) our mean duration antimicrobial treatment 16.5 (range: 6-24 Two died hospital.

Fusobacterium species are gram-negative anaerobic non-spore-forming bacteria, which colonize mucous membranes in humans. Over the recent decade, significance of these organisms has been increasingly recognized. We describe a rare case acute hepatitis, was found to be likely due nucleatum, grown on blood culture. In our case, hepatitis caused by this microorganism resolved completely without any long-term sequelae liver, through conservative management namely intravenous antibiotics and...
