Abstract

The survey was carried out in Sayes, Fangasso, Tominian and San areas, located in the region of Segou in the Sahelian zone of Mali, and concerned 384 equine and donkey sera. Of the 95 positive sera (24.73%), 92 were positive by the hemagglutination inhibition test and three by the complement fixation test. The infection rates by subtypes 1 and 2 of the equine influenzavirus found in the various visited areas were as follows: 7.37% by subtype 1, 69.47% by subtype 2, and 23.16% by subtypes 1 and 2 (mixed infection).
