Amino Acid and Protein Depletion in Medium of Cell Cultures Infected with Cowdria ruminantium
Autor: Albert W. H. Neitz, C. E. Yunker
Publikováno v: Annals of the New York Academy of Sciences. 791:24-34
Cowdria ruminantium (Rickettsiales) causes heartwater in ruminants of Africa, and some islands off Africa and in the Caribbean Sea. The in vitro culture method for the organism devised in 1985, which provided for the first time a means for production
