Abstract Background Emergence of fluoroquinolone resistance in gut pathogens is a cause concern. Resistant to quinolone mainly due the point mutations at quinolone-resistance determining regions (QRDR). The aim study was develop polymerase chain reaction-restriction fragment length polymorphism assay (PCR-RFLP) detect QRDR gyrA and gyrB enteric pathogens. Methodology PCR-RFLP done for 83 region...
In a culture survey, we found that 42% of hospital privacy curtains were contaminated with vancomycin-resistant enterococci, 22% with ethicillin-resistant Staphylococcus aureus, and 4% with Clostridium difficile. Hand imprint cultures demonstrated that these pathogens were easily acquired on hands. Hospital curtains are a potential source for dissemination of healthcare-associated pathogens.
Introduction: This study is aimed to compare phenotypic test methods and determine antibiotic susceptibility pattern of AmpC beta-lactamase producing uropathogenic Escherichia coli and Klebsiella pneumoniae in clinical isolates. Method: E. coli and K. pneumoniae were identified by standard microbiological procedures. Screening of AmpC beta-lactamase production was done by using cefoxitin disc (...
BACKGROUND AND PURPOSE While nosocomial infections cause substantial morbidity and mortality, the availability of timely and accurate epidemiological information on nosocomial pathogens is essential to the appropriate selection of empirical therapy. This study analyzed nosocomial bloodstream infections (NBSIs) surveillance data to determine trends in the distribution of pathogens and antimicrob...
BACKGROUND New therapeutic targets for antibiotic-resistant bacterial pathogens are desperately needed. The bacterial surface polysaccharide poly-β-(1-6)-N-acetyl-glucosamine (PNAG) mediates biofilm formation by some bacterial species, and antibodies to PNAG can confer protective immunity. By analyzing sequenced genomes, we found that potentially multidrug-resistant bacterial species such as Kl...
Screening for gastrointestinal colonization with multidrug-resistant nosocomial pathogens is an important component of infection control protocols. In the New York City region, carbapenem-resistant Klebsiella pneumoniae strains, which harbor the KPC carbapenem-hydrolyzing beta-lactamase, have rapidly emerged. The potential utility of screening medium, which involved using 10-mug imipenem disks,...
An estimated 2 million patients develop nosocomial infections in the United States annually. The increasing number of antimicrobial agent-resistant pathogens and high-risk patients in hospitals are challenges to progress in preventing and controlling these infections. While Escherichia coli and Staphylococcus aureus remain the most common pathogens isolated overall from nosocomial infections, c...
Serious infections caused by Gram-positive bacteria are currently difficult to treat because many of these pathogens are now resistant to standard antimicrobial agents. As a result of the emergence and spread of multidrug-resistant Gram-positive pathogens, new antimicrobial agents are urgently needed for clinical use. In recent years, there has been an increase in the number of drugs that have ...
Gowns and drapes are used widely in healthcare facilities. Gowns have been used to minimize the risk of disease acquisition by healthcare providers, to reduce the risk of patient-to-patient transmission, and during invasive procedures to aid in maintaining a sterile field. Drapes have been used during invasive procedures to maintain the sterility of environmental surfaces, equipment, and patien...
