Metabolic changes in Trichomonas gallinae resulting from growth in various carbohydrates.

The influence of the type of growth carbohydrate on the subsequent metabolic activity of Trichomonas gallinae was investigated. Washed suspensions of cells collected from CPL-glucose, CPL-maltose, CPL-galactose, and CPL-glucose-maltose media were examined in the warburg respirometer for their ability to utilize glucose, maltose, and galactose. Comparisons of the metabolic parameters of substrate consumption, changes in glycogen content, and CO2 and H2 production were made. The pattern of utilization of the sugars, both qualitatively and quantitatively, depended upon the type of carbohydrate in the CPL medium used to culture the cells and upon the time of exposure of the cells to a particular sugar in the medium.
