Clonal spread of vancomycin-resistant Enterococcus faecium between patients in three hospitals in two states.

The DNAs of 3* vancomycin-resistant Enterococcus faecium isolates from five hospitals in three states were analyzed by contour-clamped homogeneous electric field electrophoresis and plasmid analysis. There were 22 strain types. One strain type was common to patients in three hospitals in two states.

Clinical characteristics of seven cases of diarrhea associated with a novel acid-fast organism in the stool.

In the last 4 years, we have identified an acid-fast, autofluorescent organism in the stool of seven patients with diarrhea. The organism was identified as a cyanobacterium-like organism by the Centers for Disease Control (Atlanta) and as a coccidian by researchers in Peru and at the University of Arizona (Tucson). We present reports on the seven cases and a review of the literature.

Molecular typing of ampicillin-resistant, non-beta-lactamase-producing Enterococcus faecium isolates from diverse geographic areas.

Molecular typing methods were compared by using 66 ampicillin-resistant, non-beta-lactamase-producing Enterococcus faecium clinical isolates from diverse geographic areas. Whole-plasmid analysis, restriction enzyme analysis of plasmid DNA with EcoRI and HindIII, and contour-clamped homogeneous electric field electrophoresis with digestion by SmaI and ApaI were performed on all isolates. Whole-plasmid analysis identified 47 different groups.

The emergency management of moray eel bites.

As human encounters with hazardous marine life increase, emergency physicians are more frequently confronted with the management of resultant injuries. We present three cases involving hand injuries inflected by moray eels. Each was managed with local wound care and subsequent outpatient treatment with either oral ciprofloxacin or cefuroxime.
