[Some aspects of the evolution of cholera in Algeria from 1971 to 1975]

Taking as a basis information collected in their laboratory, the authors study certain aspects of the evolution of cholera in Algeria during the different outbreaks from 1971 to 1975. 6 301 strains of vibrio-cholerae (mainly serotype Ogawa) were isolated either from cholera patients or carriers. All but two of strains were sensitive to all antibiotics tested. Most of the Wilayate (districts) were affected during these outbreaks which took place from June to December; the majority of cases were observed from August to October but principally in September.
