Biological examinations are of little help to the clinical diagnosis confirmation, whereas throat culture confirm the diagnosis in most cases. Throat culture have been used to study the prevalence of beta hemolytic streptococci wihin 800 pharyngitis. The beta hemolytic streptococci have been found within 197 patients, [24.7%]. The streptococci of group A. have been found within 82 cases [10.3%]. The streptococci of groups B, C, G and F have been isolated within 115 patients [14.4%].

Epidemiological studies suggest African origin of retrouviruses of HTLV group [human T cell leukemia lymphoma virus] which are incriminated in the etiology of adult leukemia and acquired immunodeficiency syndrome [AIDS]. We have studied 610 sera of healthy subjects from different parts of Morocco. The prevalence of antibodies against HTLV[1] in this sample is weak [0,5%] similar of that shown in USA and Europe
