Abstract
The authors mentioned an epizootic infection for the chronic upper respiratory diseases caused by béta – haemolytic Streptoccocus equi which have affected horses in two localities in Dakar and Rufisque areas (Dakar’s region) in Senegal, during rainy season in 2009. These studies has been done according to clinical aspects and bacteriological and hematological analysis of the samples. The disease has been observed at the end of the rainy season and looks like an aigue form which can evolute near guerison or death. That’s the first case observed and mentioned in Senegal. Keys words: Bacteriology, chronic upper respiratory disease, dakar, dry season, hematology, infection, rainy season, Rufisque, Streptococcus, Senegal.
Highlights
The pathogen responsible for the horse strangles is Streptoccoccus equi subspecies equi Gram-positive, belonging to the family of Streptococcaceae and known from the thirteenth century in 1251 with the first descriptions by Jordann Ruffer (Timoney and Equine, 1999)

Summary
The pathogen responsible for the horse strangles is Streptoccoccus equi subspecies equi Gram-positive, belonging to the family of Streptococcaceae and known from the thirteenth century in 1251 with the first descriptions by Jordann Ruffer (Timoney and Equine, 1999). First known as S. equi, the causative agent of strangles was later renamed S. equi subspecies equi in 1984 following the work of JAE Farrow and MD Collins (Euzeby and Guerin – Faublei, 2000; Jorm, 1993). Unlike the last two, S. equi has never been implicated in cases of human disease (Jorm, 1993). This disease can be transmitted directly by oral or nasal or see through close contact with an individual with the excretory major risk of rapid spread of the disease in a number (Ames, 1995; Sweeney et al, 2005). Indirect transmission is possible through boots, overalls and all the materials that are not specific for single use (Jorm, 1993)
