We described two case reports of S. dysgalactiae subsp. equisimilis tonsillitis occurred from January 2005 to January 2007, among patients who come to our observation during these two years. These patients are paradigmatic of some conditions: adult age, absence of underlying diseases, outbreak of similar pharyngo-tonsillar sympyomatology, unsuccessful oral penicillin therapy, isolation of S. dysgalactiae subsp. equisimilis from throat swab, complete recovery after oral beta-lattamic antibiotic therapy, but total clearance of the microorganism only after oral macrolides administrations. Thus, the intracellular localization of S. dysgalactiae subsp. equismilis, could be in charge of the failure of beta-lattamic antibiotics therapy.
