title: Spiramycin: in-vitro activity on Branhamella catarrhalis.
abstract: This in-vitro study of susceptibility to spiramycin of 103 strains of Branhamella catarrhalis isolated between 1982 and 1987 was performed by evaluation of their MICs. More than 97% of strains remained susceptible with MIC less than or equal to 8 mg/l (two strains). One strain presented a MIC of 16 mg/l. There were no significant differences of susceptibility to spiramycin between penicillinase-producing and non-producing strains.
