RESUMEN
The in vitro activities of povidone iodine, potassium peroxymonosulfate, and dimethyldidecylammonium chloride were investigated against 379 nosocomial isolates of Staphylococcus aureus and Pseudomonas aeruginosa responsible for surgical wound infections in patients operated on between July 1995 and June 2001. Overall, the isolates were inhibited by the antiseptics at concentrations below those used routinely. In spite of increasing resistance to the various antibiotics used to treat surgical wound infections, no significant variation in the susceptibility to antiseptics was demonstrated during this 6-year study.

The in vitro anti-cryptosporidial activity of buforin II alone and in combination with azithromycin and minocycline was investigated. Buforin II showed moderate activity, which increased with increasing concentration to 55.7% suppression of growth at 20 microM. Moreover, its activity was enhanced when it was combined with either azithromycin or minocycline with >90% parasite reduction at the highest concentration tested. Buforin II may be active in inhibiting Cryptosporidium parvum growth in vitro upon combination with either azithromycin or minocycline.
