One and six hours after the infection, 0.1 ml consisting of increasing doses of G-6-P (0, 5, 25, 50, 250 and 500 μg/g) and decreasing doses of Fosfomycin (15.6, 7.8, 3.9, 1.95, 0.98 and 0.49 μg/g) were applied i.m., using 10 animals for each combination. Tables 1 and 2 show the results of this therapy with regard to the reduction of the ED₅₀ of Fosfomycin. It can be seen that the addition of 25 μg G-6-P/g body-weight significantly reduces the ED₅₀ within the first days (Tab. 1), while doses of 50 and more μg G-6-P/g significantly reduce the ED₅₀ during the whole investigation period (Tab. 2).
