Susceptibilidad antimicrobiana de 561 cepas de shigella obtenidas de muestras clínicas / Antimicrobial susceptibility of 561 shigella strains from clinical samples

The study of susceptibility to 11 antimicrobial by agar difusion method of 561 Shigella strains at the Enteric Reference Laboratory of I.S.P., is informed. We found 18.7 percent of resistance, a lower value than the described in the literature of other countries

Diagnóstico presuntivo rápido de enteritis asociada a campylobacter / Speed presumptive diagnosis of Campylobacter enteritis

Between january 1983 and march 1984, stool specimens from 380 children under 2 years old with complicated acute diarrhea and 20 normal children were studied. Stool specimens were obtained with rectal swabs and transported in Cary and Blair medium. Flooded slides one to 2 minutes with a mixture of equal parts Hucker's crystal violet solution and 1 percent sodium bicarbonate (VB), were prepared from each specimen and looked for seagul rods. Culture of the stool specimens were made for Campylobacter sp. isolation. In the present work the flooded slides were thought as a presumptive diagnosis and we obtained a positive sensitivity of 80 percent and a positive predictibility of 5,7 percent
