    摘要: 7-(1-Pyrrolidinyl)-3-quinolonecarboxylic acid derivatives of the formula ##STR1## in which A is CH, CCl, CF or N,R.sup.1 is hydroxyl, hydroymethyl or mercapto andR.sup.2 is hydrogen, alkyl, having 1 to 4 carbon atoms or (5-methyl-2-oxo-1,3-dioxol-4-yl)methyl,with the proviso that, when R.sup.1 is hydroxyl, A is not CF or N, or pharmaceutically acceptable hydrates, or salts thereof, are useful as antibacterials and animal feed utilization promoters.
