This study compared the antimicrobial susceptibility and genotypes of strains of Neisseria gonorrhoeae isolated from men who have sex with men (MSM) and from heterosexuals. One hundred and eleven strains were characterized from 107 patients, comprising 57 strains from 54 heterosexuals and 54 strains from 53 MSM. Antimicrobial resistance rates were higher in strains from heterosexual patients, with resistance to cefixime (P = 0·0159) and ciprofloxacin (P = 0·002) being significantly higher. Typing by N. gonorrhoeae multi-antigen sequence typing (NG-MAST) showed that the most prevalent sequence types (ST) and genogroups (G) respectively were ST2400, ST2992, and ST5793, and G1407, G2992, and G2400...

Sphingomonas paucimobilis is an aerobic, oxidase-positive, yellow-pigmented, non-fermentative, Gram-negative opportunistic pathogen that rarely causes infections in humans. It is commonly found in nosocomial environments and, despite its low clinical virulence, it can be responsible for several different infections especially among patients with underlying disease. Here we describe a clinical case of a 46-year-old male paraplegic patient with a history of neurogenic bladder due to insulin-dependent diabetes mellitus and renal failure who was admitted to the urology clinic of a university hospital in Kirsehir, Turkey, with the complaints of urinary tract infection (UTI) including fever, chills, dysuria, abdominal and back pain...

BACKGROUND: Gonorrhoea is a sexually transmitted infection caused by the Gram-negative bacterium Neisseria gonorrhoeae. Resistance to first-line empirical monotherapy has emerged, so robust methods are needed to evaluate the activity of existing and novel antimicrobials against the bacterium. Pharmacodynamic models describing the relationship between the concentration of antimicrobials and the minimum growth rate of the bacteria provide more detailed information than the MIC only. RESULTS: In this study, a novel standardised in vitro time-kill curve assay was developed...

BACKGROUND:  Treatment of Neisseria gonorrhoeae infection is empiric and based on population-wide susceptibilities. Increasing antimicrobial resistance underscores the potential importance of rapid diagnostics, including sequence-based tests, to guide therapy. However, the utility of sequence-based diagnostics depends on the prevalence and dynamics of the resistance mechanisms. METHODS:  We define the prevalence and dynamics of resistance markers to extended spectrum cephalosporins (ESC), macrolides, and fluoroquinolones in 1102 resistant and susceptible clinical N...

Enteric fever is a major cause of concern in developing countries across the globe. The primary choice of antibiotics remains fluoroquinolones, followed by cephalosporins. Resistance to third-generation cephalosporins is rarely reported in Salmonella enterica serovar Typhi. This study reports the whole genome sequence of an S. Typhi isolate resistant to cefixime [minimum inhibitory concentration (MIC)=512μg/mL] by microbroth dilution. Interestingly, the isolate was negative for the cephalosporin resistance gene blaCTX-M by PCR, which is a known mechanism for higher cephalosporin resistance...
