Sparfloxacin is a fluoroquinolone antibacterial agent with activity against a broad range of Gram-negative and Gram-positive organisms including Streptococcus pneumoniae, one of the main pathogens in community-acquired pneumonia. In this infection, sparfloxacin has shown efficacy similar to that of amoxicillin
N Rastogi et al.
Antimicrobial agents and chemotherapy, 35(12), 2473-2480 (1991-12-01)
The MICs and MBCs of the new difluorinated quinolone drug sparfloxacin against type strains belonging to 21 species of mycobacteria were screened. The MICs and MBCs were within the range of 0.1 to 2.0 and 0.1 to 4.0 micrograms/ml, respectively

Members of the fluoroquinolone class are being actively evaluated for inclusion in tuberculosis chemotherapy regimens, and we sought to determine the best in vitro and pharmacodynamic predictors of in vivo efficacy in mice. MICs for Mycobacterium tuberculosis H37Rv were 0.1

Antimicrobial agents and chemotherapy, 52(10), 3823-3825 (2008-07-23)
A new chromosome-carried quinolone resistance gene from Stenotrophomonas maltophilia, Smqnr, was characterized. The gene was present in type strain CCUG 5866 and was also detected in 24 clinical isolates and showed some allelic diversity. The expression of Smqnr in Escherichia

In defined, isogenic strains, at least three mutations, two of which must be in gyrA, were required to exceed the CLSI breakpoint for fluoroquinolone resistance. Strains with double mutations in both gyrA and parC had even higher MICs of fluoroquinolones
