[Salmonella and salmonellosis in the Asturias District, Spain, during a seven year period (1990-1996)].

Abstract

BACKGROUND Retrospective study of the Salmonella sp. strains and human salmonellosis episodes registered in the Public Health Laboratory of the Principado de Asturias, Spain, over the seven year period 1990-1996. MATERIAL AND METHODS All strains were serotyped; strains of serotypes Typhi and Typhimurium were also phage typed. The strains were grouped according to: sample of origin, age group; season of the year; time distribution, and epidemiological presentation (sporadic episode or outbreak). RESULTS AND DISCUSSION A total of 3,255 Salmonella isolates were registered and conserved in the period under study. They were adscribed to 45 serotypes, being Enteritidis, Typhimurium, Virchow and Hadar (57.1, 26.6, 4.5 and 2%, respectively) the most frequent. 3,193 isolates were collected from clinical samples (corresponding to 3,067 patients), 32 from environmental water or sewage, 28 from food and 2 from animal stools. Relevant epidemiological findings were: the most affected age group was children under 4 years old (32.3%), the season with highest incidence was the summer. The most frequent clinical presentation was the sporadic episode of gastroenteritis (97%). Seventy five outbreaks (22 communitary and 53 family) were registered, being associated with six serotypes: Enteritidis (76%), Typhimurium, Virchow, Hadar, Infantis and Coehl.
