SOUZA, Roberta B. et al. Ciprofloxacin susceptibility reduction of Salmonella strains isolated from outbreaks. Braz. J. Microbiol. [online]. 2010, vol.41, n.2, pp. 497-500. ISSN 1517-8382. http://dx.doi.org/10.1590/S1517-83822010000200033.
The antimicrobial susceptibility of 212 Salmonella strains isolated from patients and foods was evaluated and 45% were found to be resistant to nalidixic acid. Nalidixic acid resistant strains showed a higher minimal inhibitory concentration for ciprofloxacin than sensitive strains. During the study an increase of strains with reduced susceptibility to ciprofloxacin was also observed.
