title: [Isolation of a carbon dioxide-dependent strain of E. coli from the urine of a patient with chronic pyelonephritis (author's transl)].
abstract: Since anaerobic culture techniques were introduced into bacteriological routine laboratories reports increase about Enterobacteria, which doesn't grow under normal culture conditions. We recently isolated a carbon-dioxide dependent strain of E. coli, which didn't grow aerobically even on optimized culture mediums. Though the species was at first isolated in an anaerobic jar further investigation showed optimal growth in an atmosphere containing 20 per cent oxygen enriched with (10 per cent) carbon dioxide. There are some indications that the mutant developed under chemotherapy. A serological grouping wasn't possible.
