[Evolution of the repartition of enteropathogenic enterobacteria serotypes isolated in Algeria from 1974 to 1977].

The authors survey the enteropathogenic enterobacteria studied from 1974 to 1977 and draw the following conclusions : S. typhi is still the predominant serotype. Among Salmonella, other than S. typhi and S. paratyphi, S. wien remains the most frequently reported serotype while progressively decreasing from 1974 to 1976 and is supplanted by S. infantis in 1977. Among the 847 strains of Shigella examined, a high frequency of Shigella flexneri is noted with Shigella sonnei following by a wide margin. As regards the enteropathogenic E. coli the serotypes 0111 : K 68 (B4) and 0125 : K 70 (B15) were isolated, frequently from 1974 to 1976 but the serotype 0119 : K 69 (B14) became the most frequent in 1977.
