Pathogenicity of Pseudomon as Fluorescensand Related Pseudomonads to Warm-Blooded Animals

Abstract

P. fluorescens and related species of pseudomonads that are generally thought to be plant pathogens seemed to be effective in producing lesions in warm-blooded animals when the organisms were placed in contact with open wounds of the parts of the bodies that have temperatures less than 37[degree]C. Invasion of the blood stream from such lesions occurred, but the organisms seemed to be ineffective in causing infection in the internal organs of the animals. The classification of pseudomonads into animal pathogens and plant pathogens, therefore, does not seem to be a sound practice, because P. aeruginosa, which is generally thought to be an animal pathogen, has been demonstrated to be also phytopathogenic.
