[Evaluation of penicillin alone and penicillin combined with anti-anthrax serum in experimental anthrax in mice].

In this study penicillin alone versus penicillin combined with anti-anthrax serum were compared in the treatment of experimental anthrax of mice. Three groups of mice were inoculated intraperitoneally with the same suspension of Bacillus anthracis. Ten hours after the onset of infection the control group received no treatment, to the second group penicillin-G was injected every day, and the 3 rd group received penicillin-G plus anti-anthrax serum. The survival rate of the latter two groups was significantly higher than that of the control group. But, there was no difference in the survival of mice and the distribution of the bacilli in various tissues between the penicillin treated mice and the penicillin plus anti-anthrax serum treated group of mice.
