Physiology of Rickettsiae VII. Amino Acid Incorporation by Coxiella burnetii and by Infected Hosts

RESUMO
Protein synthesis, in terms of 14C-labeled amino acid incorporation into a hot trichloroacetic acid fraction, was studied in cell-free preparations of Coxiella burnetii, and in uninfected and Q fever-infected guinea pig and chick embryo hosts. Purified and disrupted suspensions of C. burnetii incorporated 14C-labeled l-leucine, l-phenylalanine and algal hydrolysate. Livers of infected guinea pigs and chick embryos had a greater incorporation rate at the height of infection than comparable preparations from uninfected animals. As chick embryonic development continued during infection, the rate of incorporation progressively decreased below that of uninfected embryos.
