[Salmonella ssp non-typhi focal infections].

Provided here are the descriptions of 18 patients with focal infections caused by Salmonella spp no-typhi occurring in a period of seven years at the Puerta de Hierro Clinic. In all cases, there was at least one local factor, treatment, or underlying illness associated with decreased resistance to infection. Antecedents of severe gastroenteritis were found in seven cases (38 percent). Eighty-three percent had previous or concomitant bacteremia caused by the same serotype of Salmonella isolated in the focal infection. S. enteritidis was the most prevalent serotype (66 percent). The most common localizations were plueropulmonary (5), osteoarticular (5), and intravascular (3). Relapsing infection was demonstrated in five cases. There was 28 percent mortality. Statistically, age greater than 65 years and the absence of surgical intervention were associated with a worse prognosis.
