Abstract: | An outbreak of penicillin-resistantStreptococcus pneumoniae (PRSP) infections occurred in our hospital between January and May of 1993. Nine patients with infections/colonizations were
located in 3 multiplebed rooms on an internal medicine ward. Two of the 9 patients developed pneumonia, 3 developed acute
bronchitis, and 4 patients demonstrated colonization in the respiratory tract. Only 1 case of acute bronchitis was confirmed
as a community-acquired infection, while the others were considered nosocomial infections, subsequently shown to be caused
by at least 2 different bacterial strains. The cases of pneumonia were thought to be cross-infections transmitted by droplets.
All patients with either pneumonia or bronchitis were cured by the administration of various antibiotics, including imipenem
and ofloxacin. Of the 4 colonization cases, 3 patients were treated with antibiotics and the organisms successfully eradicated.
Although all 5 patients with infections were cured, it is important to be attentive to the emergence of PRSP infections, as
there are potential difficulties in the treatment of this organism. |
