Exogenously supplied pyochelin influenced the virulence of Pseudomonas cepacia pyochelin-negative strains in a chronic pulmonary infection model in rats. Groups of rats were inoculated transtracheally with agar beads containing P. cepacia or P. aeruginosa strains, saturated with either pyochelin or PBS. Supplementation of the inocula with pyochelin had no effect on the number of bacteria recovered from the lungs. The availability of pyochelin, however, increased the degree of pathology observed in lungs infected with pyochelin-negative strains of P. cepacia. The area of pathological involvement in the lung was about 2-fold larger, when pyochelin was present. Inclusion of pyochelin in the inoculum had no effect on the degree of pathology observed in lungs infected with a pyochelin-positive P. aeruginosa strain. Pyochelin was shown to stimulate in vitro growth of P. cepacia, but it had no effect on production of lipase or protease, factors which may be involved in P. cepacia virulence. These studies support our hypothesis that pyochelin may be important for dissemination in P. cepacia infections.
