MORA-MORA, Minar; SOTO, Lisbeth  e  SALVADOR, Gonzalo. Diarreas asociadas a Shigella con un patrón de resistencia antimicrobiana alto en el cantón de Coto Brus, Costa Rica. Rev. costarric. cienc. méd [online]. 2003, vol.24, n.1-2, pp.55-60. ISSN 0253-2948.

Among 420 diarrheic simples from patients from the San Vito Hospital, Puntarenas, Costa Rica, were essayed from 2001, January to 2002, January. The percentage of resistance of Shigella sp; to eight of the first line antibiotics, was determined. The 65.1 % of the strains were isolated between October and December of 2001. One hundred and forty two of the strains isolated were Shigella flexneri and six were Shigella sonnei. The 70% of the strains shown resistance to Trimethoprim / Sulfametoxazole, tetracycline and ampicillin. AII of the strains were susceptibles to gentamicin, cefotaxime and ciprofloxacin. The case studies determined that most of the strains isolated, have an higher resistant rate to the most used antibiotics in treatment against diarrheic illness. For hence, it is important the continual monitoring of the resistance patterns for a subsequentt reatment.
