The clinical findings relating to 11 patients in Hong Kong (HK) and to 43 patients described elsewhere, all with Streptococcus zooepidemicus septicaemia, are reviewed. There was a particular association with cardiovascular disease (27%) with seven cases of endocarditis, three of abdominal aortic aneurysm and two of deep venous thrombosis. Associations not previously reported included two cases of pharyngitis and two patients with persistent post-operative fever. The overall mortality was 22%. Both human and porcine strains of S. zooepidemicus from HK did not hydrolyse aesculin in contrast to the aesculin-positive biotypes reported previously. HK strains also had very mucoid colonies and capsules of hyaluronic acid were seen in electron micrographs. Samples of chromosomal DNA, extracted by means of HindIII restriction endonuclease, of strains from human beings and pigs were identical. The MIC of penicillin for all strains was less than or equal to 0.03 mg/l but the MBC for all was greater than 32 mg/l. Penicillin alone is generally sufficient for cure but combination with an aminoglycoside may be indicated in seriously ill patients. In our locality, pigs were incriminated as a possible source of human infection whereas consumption of contaminated dairy products is important elsewhere.

The association of penicillin-tolerant streptococci with reported epidemics of streptococcal pharyngitis in Israel was studied. The streptococcal strains had been isolated during 11 epidemics of community-acquired pharyngitis and 6 food-borne epidemics of pharyngitis occurring in the last 15 years. Strains were stocked lyophilized. Isolates were defined as tolerant if the MBC/MIC ratio for penicillin was greater than or equal to 32. All 122 group A streptococcal strains isolated during the epidemics of community-acquired infection showed tolerance to penicillin. In contrast, none of the 52 strains from food-borne epidemics (24 group A, 18 group C and 8 group G) was tolerant.

Twenty-four strains of non-toxigenic Corynebacterium diphtheriae biotype gravis from the throats of patients with pharyngitis/tonsillitis were assayed for susceptibility to penicillin and erythromycin using determination of MIC, MBC and time-kill curves. There were no differences between the MICs of penicillin for susceptible and tolerant strains. All but one strain had penicillin MBCs > or = 2 mg/L. Seventy-one per cent (17/24) of the strains were tolerant to penicillin. In contrast, all strains were susceptible to erythromycin (MIC < or = 0.016 mg/L). These aspects should be considered when choosing the therapy for treating non-toxigenic C. diphtheriae pharyngitis/tonsillitis.
