Strains of Pseudomonas putrefaciens from clinical material

Eight strains of Pseudomonas putrefaciens have been received from among 466 strains of Pseudomonas submitted to the Computer Trials Laboratory for identification over the last eight years. Two of the strains of P. putrefaciens from patients with otitis media and otitis externa respectively appear to have played a pathogenic role. The biochemical characteristics of these eight strains were compared with those of seven culture collection strains.
