OCULAR infections due to Aerobacter aerogenes have not been reported so far as can be determined. In 3,630 preoperative cataract cultures, A. aerogenes has been found only once.1 However, 10 cases of chronic conjunctivitis due to A. aerogenes have been encountered in this laboratory in the last 10 years. The strains tested have proved sensitive to streptomycin. This organism is widely distributed in nature,2 being found in the soil, in feces, in water and in milk. Besides being present in the upper regions of the intestinal canal, it may cause infections of the urinary tract in man.
