Proteus species isolated from human eyes.

Of 34 species of Proteus isolated from human eyes, 29 (85%) were P. mirabilis and five (15%) were P. morganii. In vitro antibiotic sensitivity studies showed that gentamicin best controlled both P. mirabilis and P. morganii of all the antibiotics tested. In vivo tests on experimental Proteus infections of rabbit coreas, treated with gentamicin and tobramycin, yielded comparable clinical results, but gentamicin was more effective in eliminating the organism from the experimental lesions.
