In the Republic of Benin, abortion is one of the reproductive problems on small ruminant farms, and Chlamydia abortus is one of the causative agents. The aim of this study was to determine for the first time the serological prevalence and hematological parameters in small ruminants positive for Chlamydia abortus in Benin, mainly in the department of Ouémé. It covered five sites, namely Akpro-Missérété, Avrankou, Adjarra, Sèmè-Kpodji and Dangbo in the Ouémé department. A total of 385 sera (200 sheep and 185 goats) from subjects showing signs of reproductive loss were tested using the indirect Elisa method. Of the 385 sera tested, 30 (7,79%) were positive for Chlamydia abortus. Similarly, the blood of animals tested positive was analyzed for hematological parameters using Sysmex XN-Series automated blood analyzer. Different variations with significant differences in some hematological parameters of the red line and those of the white line, depending on the study sites, species, age and physiological stage of the animals (hemoglobin, mean corpuscular volume for the red line at the sites, lymphocytes and basophils for the white line at the sites; hemoglobin for the red lineage and lymphocytes for the white lineage at species level; lymphocytes at age level; lymphocytes, monocytes and basophils for the white lineage at physiological stage level) were observed in animals suffering from C. abortus.
