The spread of multidrug-resistant Pseudomonas aeruginosa isolates constitutes a serious clinical challenge. Bacterial efflux machinery is a crucial mechanism of resistance among P. aeruginosa. Efflux inhibitors such as phenylalanine arginyl β-naphthylamide (PAβN) promote the bacterial susceptibility to antimicrobial agents. The pathogenesis of P. aeruginosa is coordinated via quorum sensing (QS...

PURPOSE To determine the minimum inhibitory concentrations (MICs) of 12 antimicrobials in current ophthalmic use and 4 potentially new alternatives against isolates from bacterial keratitis. METHODS Bacteria were collected from cases of bacterial keratitis in six centers in the United Kingdom between 2003 and 2006. MICs were measured by using susceptibility strips containing a concentration g...

Tigecycline is regarded as a last-resort treatment for multidrug-resistant Acinetobacter baumannii. However, tigecycline resistance in A. baumannii has increased worldwide. In this study, we investigated heteroresistance isolates from South Korea. Antibiotic susceptibility testing was performed on 323 nonduplicated isolates. Among 260 and 37 tigecycline-susceptible -intermediate-resistant isola...

ObjectivesMeningitis in neonates and young infants leads to significant morbidity mortality worldwide. This study aimed investigate pathogens, antibiotic resistance secular change of incidence Hong Kong.MethodsA retrospective search was performed on meningitis aged <3 months three Kong public hospitals from 2004 2019. Medical charts were reviewed, with focus the identification pathogens.Results...

BACKGROUND Over the last few decades the ever-increasing level of bacterial resistance to antimicrobials has been a cause of worldwide concern. Fluoroquinolones, particularly ciprofloxacin has been used indiscriminately for both gram-positive and gram-negative bacterial infections. The increased use of ciprofloxacin has led to a progressive loss of bacterial susceptibility to this antibiotic. T...

Third-generation cephalosporins are an important class of antibiotics that are widely used in treatment of serious Gram-negative bacterial infections. In this study, we report the isolation of bacteria resistant to the third-generation cephalosporin cefotaxime from cattle with no previous cefotaxime antibiotic exposure. The prevalence of cefotaxime-resistant bacteria was examined by a combinati...

The study was carried out to test the in vitro activity of human platelet microbicidal protein (hPMP) on most commonly isolated urethral pathogens and compare the same with clinical isolates from cases of chronic prostatitis (CP). Urethral isolates of Staphylococcus aureus (n=19), coagulase negative staphylococci (n=40) and Enterococcus faecalis (n=16) from patients with or without CP were test...

A retrospective analysis of the diagnostic laboratory submissions from 2016 to 2020 was performed assess antibiotic resistance Staphylococcus pseudintermedius and determine locations in hospital which might be acting as environmental source(s). Previous studies have identified a significant increase infections with S. pseudintermedius. Samples were taken environment by swabbing areas intensive ...

Municipal biosolids produced during activated sludge treatment applied in wastewater treatment plants, are significant reservoirs of antibiotic resistance, since they assemble both natural and fecal microbiota, as well as residual concentrations of antibiotic compounds. This raises major concerns regarding the environmental and epidemiological consequences of using them as fertilizers for crops...
