Salmonelas en la carne de consumo molida / Salmonella en chopped meat for human consumtion

Four hundred and thirty-four samples of chopped meat were examined for Salmonella serotypes; of these, 244 samples came from five rural butcher shops in the Barba Canton, and 190 from five butcher shops in the capital city of San José, in Costa Rica

Micro-organisms of the genus Salmonella were isolated from 40 (9,2 percent) of the samples. More samples from butcher shops in the city (17,9 percent positive) proved to be contaminated than from the rural butcher shops (2,5 percent positive). Possible causes of this differences are discussed

In all, 43 strains were isolated, and 10 serotypes identified, predominant among them being S. anatum and S. derby; the significance of this finding is discussed. Three samples were contaminated with two Salmonella serotypes, and Shigella boydii 5 was isolated from another(AU)

Prevalencia de bacterias enteropatógenas en Costa Rica / Prevalence of enteropathogenic bacteria in Costa Rica

In a study made of the bacterial etiology of diarrheal cases in Costa Rica, pathogenic strains of E. coli were rarely found but Shigella were found in the same proportion as in the other areas of Latin America. Salmonella occurred frequently in urban centers. Concomitant examination in children of similar age group but without diarrhea suggested that enteropathogenic. E. coli was an important cause of the intestinal symptoms; Shigella prevalence, although it increases with increasing age, loses importance as the cause of symptoms; and in the urban centers Salmonella was important as the cause of symptoms only among children under six months of age(AU)
