| Abstract: | Trimethoprim (TMP) 10 mg.kg-1 was given orally to calves and rabbits. Two to three weeks later the animals were pretreated by i.v. Peptidoglycan (Pt) 20 micrograms.kg-1. One hour later TMP was administered as above. To other animals under otherwise identical conditions TMP was injected intravenously. The pretreatment with Peptidoglycan induced in both species a significant increase of TMP serum levels positively correlated with temperature elevation. Peptidoglycan pretreatment increased the bioavailability of TMP. |
