OBJECTIVE The objective with this study was to determine and follow antimicrobial resistance in faecal bacteria over time in hospital wastewater pipe sediment. A further aim was to determine bacterial growth rates of sensitive, intermediate and resistant intestinal enterococci in different ciprofloxacin concentrations as a measure of bacterial fitness. METHODS A system enabling the collection...

BACKGROUND Enterococci normally inhabit the intestinal tract of humans and are also a potential pathogen in causing nosocomial infections. The increase in antibiotic resistance and transfer of antibiotic resistance gene to Staphylococcus aureus (S. aureus) due to co-colonization has increased its importance in research. The aim of the study was to evaluate local epidemiology of nasal and rectal...

The in vitro activity of mezlocillin was compared to penicillin G, ampicillin, carbenicillin, and ticarcillin in tests with 195 gram-positive bacteria and 20 Haemophilus influenzae. Against gram-positive isolates excluding enterococci, penicillin was the most active drug, followed by ampicillin, mezlocillin, carbenicillin, and ticarcillin. Ampicillin was the most active of the five drugs agains...

BACKGROUND Enterococci are important pathogens in nosocomial infections. Various types of antibiotics, such as aminoglycosides, are used for treatment of these infections. Enterococci can acquire resistant traits, which can lead to therapeutic problems with aminoglycosides. OBJECTIVES This study was designed to identify the prevalence of, and to compare, the aac(6')-aph(2") and aph(3)-IIIa ge...

Background: Enterococci spp. bacteria especially Enterococcus faecalis and E. faecium have the ability to acquire antibiotic-resistance pattern and causing life-threatening hospital-acquired infections. So, the aim of this study was to count and isolate of E. faecalis and E. faecium from milk and dairy desserts consumed in Assiut city, Egypt. Methods: A total of 100 raw milk, ice cream, mehall...

Background: Enterococci are intrinsically resistant/tolerant to various antimicrobial agents and can also acquire combine different mechanisms of resistance, including quorum-sensing regulation, most active compounds, which makes enterococcal infection treatment even more challenging. The aim this study was evaluate the pattern resistance analyze frequency asa1 esp genes in clinical isolates re...

Enterococci are important pathogens causing nosocomial infections and patients at risk include also premature babies requiring intensive care treatment. Our aim was to assess occurrence and cross transmission rates of enterococci among neonatal patients of a hospital ward during a two months period. Rectal and skin samples were taken between day one and 60 of infants' age. Colonization with var...

Large amounts of tylosin, zinc-bacitracin, and avilamycin are currently used as prophylactics in New Zealand broiler production. Avoparcin was also used from 1977 to 2000. A total of 382 enterococci were isolated from 213 fecal samples (147 individual poultry farms) using enrichment broths plated on m-Enterococcus agar lacking antimicrobials. These isolates were then examined to determine the p...

Enterococci are important because of their role as the leading cause of nosocomial infections which have a significant role in the dissemination and persistence of antimicrobial resistance genes. Methods: In this study, we determined the distribution of enterococcal species in the sewage treatment plants in Iran. Furthermore, we improved a rapid and specific PCR method using primers (sodA and ...
