Clinical, epidemiologic and microbiologic features of a persistent outbreak of amikacin-resistant Serratia marcescens.
This article describes a prolonged outbreak (January 1977 to February 1980) of amikacin-resistant Serratia marcescens (ARSM) urinary infections and the methods used for its control. Significant factors predisposing to ARSM urinary tract infection included an extended hospital stay, being in the urology ward, and undergoing urologic surgery. There had been on prior administration of amikacin or of other aminoglycosides in 20 of 27 patients with ARSM urinary tract infections. Chronically infected patients who required multiple hospitalizations represented a major reservoir for the perpetuation of the outbreak, overshadowing the importance of aminoglycoside use. Traditional control measures and even a major change in the inanimate environment were only partially effective in controlling the outbreak, but treatment of bacteriuric patients in the urology unit with "second and third generation" cephalosporins interrupted patient-to-patient transmission. No new cases of ARSM bacteriuria appeared in the urology unit in the ensuing 12 months.

Inactivation of clinical isolates of Herpesvirus hominis, types 1 and 2, by chemical contraceptives.
Two chemical contraceptives were examined for virucidal effects against four strains each of Herpesvirus hominis, type 2 and 1. Seven of the strains represented recent clinical isolates; one strain was a type 2 prototype. Either psermicide reduced the infectivities ofall eight viruses after contact for 10 minutes at room or body temperature. The new spermicide-germicide, compound A, produced an antiviral effect at the low concentration of 0.05%, whereas the commercially available Preceptin was effective at 5%, but not at 0.5%. The substantial loss of viral infectivity was due to direct inactivation of virus by the spermicides and was not secondary to cytotoxicity or induction of interferon in the cell cultures used for the assay. These in vitro findings hold primse for the interruption of the sexual transmission of H. hominis.
