[Occurrence of group (genus) specific Chlamydia antibodies in the blood of patients with tonsillo-pharyngitis].

A prospective study of 108 persons form Novi Sad population aged from 1 to over 40 years with tonsylopharingitis, showed that in 21.3% of the throat smears pyogenic streptococcus was present. In the blood serum, both in streptococcus positive and streptococcus negative subjects we confirmed the presence of antistreptosolin-0-antibodies. The occurrence of these antibodies was higher (p < 0.05) in streptococcus positive patients, especially in those aged from 1 to 14 years. On the basis of simultaneously proved presence of group (genus) specific antibodies to Chlamydia organisms in 26.8% of the patients, in titre value > or = 1/64, the authors point to the necessity of further systematic studies on etiologic role of Chlamydia pneumoniae in the development of acute tonsylopharingitis.
