We report the identification and characterization of three Staphylococcus aureus isolates recovered from throat and vaginal cultures, as well as from an axillary abscess, of a 17-year-old female who died of tampon-related toxic shock syndrome. The three S. aureus isolates were unrelated as determined by pulsed-field gel electrophoresis. The vaginal isolate was mecA, Panton-Valentine leukocidin,...

Avibacterium paragallinarum is Gram-negative bacteria that cause infectious coryza (IC), an acute respiratory disease of chickens. Despite vaccination of Layer and breeder farms of Iran against IC, they are still experiencing the disease clinically and there is no knowledge of serotypes prevalence of this bacterium in this country. This study designed to determine serovar identity by molecular ...

This study presents three genomes of O91:H21 isolates, two from hemolytic uremic syndrome patients and one of porcine origin. Genome analyses reveal that one of the human isolates contains both Shiga toxin-encoding genes (stx1 and stx2), and all three isolates contain putative adhesin (iha and eaeH) and antibiotic resistance (ampC) genes.

We compared 61 Shiga toxin-producing Escherichia coli (STEC) serogroups from 448 food isolates with 71 STEC serogroups from 1,447 isolates from patients in Germany. Two thirds (41/61), representing 72% of food isolates, were also found in patients. Serogroups typically isolated from patients with hemolytic uremic syndrome were rarely found in food.

BACKGROUND Nontyphoidal Salmonella is a leading cause of foodborne illness. Few studies have explored the health consequences of antimicrobial-resistant Salmonella. METHODS The National Antimicrobial Resistance Monitoring System (NARMS) performs susceptibility testing on nontyphoidal Salmonella isolates. The Foodborne Diseases Active Surveillance Network (FoodNet) ascertains outcomes for pati...

BACKGROUND Metronidazole is drug of choice recommended by WHO for treatment of trichomoniasis, however, some reports claims drug resistance in Trichomonas vaginalis isolates recently. The objective of this study was to determine the minimum lethal concentration (MLC) of metronidazole in resistant and sensitive strains, as well as genetic patterns of these stains by PCR method. METHODS From Fe...

purpose: dry eye syndrome is a multifactorial disorder of the tear film and ocular surface that results in eye discomfort, visual disturbance, and often ocular surface damage. studies suggest that the prevalence of clinically diagnosed dry eye syndrome (des) is 0.4%. to 0.5%, which is highest among women and the elderly. the burden of des can be substantial, affecting visual function, daily act...
