Abstract
Antimicrobial resistance trends were examined for 811 salmonella isolates from humans
collected in Finland during 1995–1997. The material was divided into domestic and
foreign isolates according to the origin of infection. A total of 2.3% of the 387 domestic
and 7.8% of the 424 foreign isolates were quinolone-resistant (P < 0.001).
Among the domestic isolates we detected an emergence of ciprofloxacin resistance (MIC 
0.25 mg/L) with the proportion of resistant isolates increasing from 0 to 2.2% (P
= 0.2). Among the foreign isolates this increase was even more dramatic, from
2.0% to 8.4% (P = 0.037) during the study period.
