Immunotherapeutic modification of Escherichia coli peritonitis and bacteremia by Tinospora cordifolia.
We present here the protective effects of an Indian medicinal plant Tinospora cordifolia as compared to gentamicin in E. Coli induced peritonitis. Pretreatment with tinospora cordifolia or gentamicin reduced mortality in mice injected with 1 x 10(8) E. coli intraperitoneally from 100% in controls to 17.8% and 11.1% respectively. This was associated with significantly improved bacterial clearance as well as improved phagocytic and intracellular bactericidal capacities of neutrophils in the Tinospora cordifolia treated group. In the gentamicin treated mice although bacterial clearance was rapid, polymorph phagocytosis was depressed. Tinospora cordifolia did not possess in vitro bactericidal activity. The results demonstrate that a "prohost approach" may be beneficial in the therapy of peritonitis.
