Abstract
Zusammenfassung
Vorliegende Arbeit beschreibt thyminbedurftige (thym∼)-Mutanten von schweinepathogenen Oedemcoli des Serotyps 0139:82 B. 4,6% der untersuchten E. coli 0139 waren thyminbedurftig und haben ihre pathogenen Eigenschaften beibehalten. Die isolierten thym∼-Mutanten wurden in den Schweinehaltungsbetrieben hochstwahrscheinlich durch trimethoprimhaltiges Medizinalfutter selektioniert. Im Routinelabor konnen solche E. coli wegen ihren veranderten Eigenschaften zu falschen Diagnosen fuhren.
Summary
Thymine-dependent mutants of pig pathogenic oedema E. coli of serotype 0139:82 B
This paper describes thymineless (thym∼) mutants of E. coli 0139:82 B which causes oedema disease of piglets. 4.6% of the E. coli 0139 strains examined were thymineless mutants which have kept their pathogenic characteristics. The isolated mutants have probably been selected on the farms by the use of co-trimoxazole-containing food. In the routine laboratory, such E. coli could cause false diagnosis with regard to their changed biochemical and morphological properties.
