ABSTRACT
Twenty-three isolations of Serratia spp were made from 21 horses at the University of Florida Veterinary Medical Teaching Hospital between Jan 1, 1979 and July 1, 1983. Three Serratia spp were involved in single-organism and mixed infections of various tissues. Eight horses of this group died. All horses that died had massive, mixed, gram-negative infection. The other 13 responded to treatment, including systemic antibiotic therapy. Most of these horses were stressed and under antibiotic therapy prior to the time of culture. Possible nosocomial infection, variable antibiotic sensitivity, and a trend toward decreased antibiotic sensitivity after antibiotic administration were noted.

Primary isolation of Prototheca was accomplished on MacConkey's, sheep blood agar, and Sabouraud dextrose agar. Prototheca was differentiated from similar organisms by its ability to grow on MacConkey's agar, and by its colonial morphology. Further differentiation was based on staining procedures to reveal the characteristic microscopic morphology. In the process of identification of several isolates of Prototheca zophii obtained from animal sources, a simple guideline for isolation and identification of these organisms was developed.
