Mahadevan and Tatum's method was used to isolate four fractions from the bacterial walls of Brucella abortus 99. Determined were the amino acid composition and the purity (by means of the complement fixation test) of these fractions. Infrared spectroscopy was carried out as well. It was found that: 1. The particular fractions differ by their amino acid composition. 2. The fractions are practically pure. 3. The functional groups established confirm previous data of the author on the chemical composition of the wall, and give an idea about the distribution of these groups among the individual fractions. The fractions obtained prove to be the building ingredients of the Brucella abortus 99 bacterial wall.
