ARIAS B, Isabel  e  MEZA L, Ana. Resistencia antimicrobiana de Salmonella, Shigella y Vibrio cholerae: Perú 1997-2002. Rev. perú. med. exp. salud publica [online]. 2004, vol.21, n.4, pp.273-275. ISSN 1726-4634.

Antimicrobial resistence is a public health problem, in this study we present results of antimicrobial resistance between 1997 and 2002 in Salmonella, Shigella, and Vibrio cholerae strains from regional reference laboratories and various health units that were assessed by the Peruvian National Institute of Health. Identification confirmation was performed using biochemical tests and serotyping; susceptibility testing was performed using disk-difusion tests. 524 Salmonella strains, 1034 Shigella strains, and 603 Vibrio cholerae strains were studied. 74,4% Shigella strains were ampicillin-resistant; 65.9% were chloramphenicol resistant, and 72,2% were cotrimoxazole resistant. 3,46% Salmonella strains were ampicillin resistant; 2.83% were chloramphenicol resistant, 3,9% were gentamycin resistent, and 1,1% were cotrimoxazole resistant. 19% Vibrio cholerae strains were cotrimoxazole resistant, 12,1% were tetracyclin resistant, and 10.2% were ampicillin-resistant between 1997 and 1999. Since year 2000, no Vibrio cholerae cases were reported, and we received very few strains of this species. There is evidence of Shigella resitance to ampicillin, chloramphenicol, and cotrimoxazole.
