Activity of Two Cefepime-Based Novel Combinations, Cefepime/Taniborbactam and Cefepime/Zidebactam, against Carbapenemase-Expressing Collected in India.

In recent times, discovery efforts for novel antibiotics have mostly targeted carbapenemase-producing Gram-negative organisms. Two different combination approaches are pertinent: β-lactam-β-lactamase inhibitor (BL/BLI) or β-lactam-β-lactam enhancer (BL/BLE). Cefepime combined with a BLI, taniborbactam, or with a BLE, zidebactam, has been shown to be promising.

Multidrug resistant Salmonella typhi in Calicut, south India.

Eighty S. typhi strains isolated during the period of one year (July 1989 to June 1990) were tested for susceptibility to chloramphenicol, ampicillin, cotrimoxazole, gentamicin, kanamycin, cefazolin, furazolidone and ciprofloxacin. Determination of minimum inhibitory concentration (MIC) by tube dilution method showed that the multiply resistant S.
