On diagnosis of typhoid fever, majority (55%) of the GP's prescribe quinolones followed by 3rd generation cephalosporins by 40% GP's, chloramphenicol by 2% GP's and ampicillin/cotrimoxazole by 1%GP's while 2% GP's prescribe other than these drugs (table).
This study searched to verify the possible presence of antibiotic residues in pasteurized and unpasteurized milk, produced and marketed in the microregion of Capanema, State of Parana, Brazil, through qualitative screening methods for detection of four different groups of drugs, [beta]-lactams, tetracyclines, quinolones and sulfonamides, to map the status of the chemical milk quality in respect of contamination by antibiotic residues.

maltophilia has identified a novel family of resistance genes (smqnr) encoding proteins containing pentapeptide repeats, which confer low-level resistance to quinolones (10).
The link was seen with many classes of antibiotic - including macrolides, quinolones, tetracyclines, sulphonamides and metronidazole.

Regarding the quinolones, there are four known mechanisms of resistance that work separately or in combination, resulting in varying degrees of resistance that range from reduced susceptibility to clinically relevant resistance.
