Colpidium campylum

Dive, D., Blaise, C., Robert, S., Le Du, A., Bermingham, N., Cardin, R., Kwan, A., Legault, R., Mac Carthy, L., Moul, D. and Veilleux, L. (1990) Canadian workshop on the Colpidium campylum ciliate protozoan growth inhibition test, Zeitschrift fur angewandte Zoologie 76 (1), 49-63. 

Only a very small number of doublets are significant, for example Paramecium caudatum with Zoogloea Colpidium campylum with Paramecium trichium or with Fusarium or with Stigeoclonium. Mass development of Colpidium campylum in the absence of other ciliates is also significant. 

Speck, Moulder, and Evans have shown for a unicellular organism, the protozoon Plasmodium gallinaceum, that the mechanism of oxidation of pyruvate resembles very closely that in pigeon breast muscle. A dicar-boxylic acid is required and the effect of this dicarboxylic acid is catalytic. Malonate inhibits the oxidation of pyruvate and other substrates and causes an accumulation of succinate. The di- and tricarboxylic acids of the cycle are all readily oxidized by the organism. Seaman obtained similar results with the ciliate Colpidium campylum.
