Abstract: | Four strains of the phytopathogenic bacteriumCorynebacterium fascians (Tilford)Dowson were selected from our isolates and deposited in the Czechoslovak National Collection of Type Cultures (CNCTC) of the Institute
of Hygiene and Epidemiology in Prague. Two very virulent (Cor 83/82 “UPR” and Cor 82/81 “UP”) and one avirulent (Cor 81/80
“CP1b”) pelargonium strains, producing acid from rhamnose, were isolated from fasciations onPelargonium zonale W. One avirulent celery strain ofC. fascians (Cor 80/80 “CF4a”) was isolated from a root expiant ofApium graveolens L. growing on a nutrient mediumin vitro. Morphological, cultural, physiological and biochemical characteristics of these selected Czechoslovak isolates were compared
with the American patented strain cotype ATCC 12974. |
