Pentavalent EDTA-Sodium-extract-vaccines and monovalent EDTA-Sodium-extract-vaccines obtained from swine-pathogenic E. coli and produced in Berlin-Buch were used in field trials to test their antiepizootic effect in industrial pig-farms in the district of Wrocław. The pentavalent vaccine contained extracts from E. coli O138, O139, O141, O147, and O149, whereas extracts from O8, O115 and O149 were used as monovalent vaccines. The field trials were conducted as blind trials is closed stocks of pigs. We employed direct oral immunization of suckling piglets and indirect immunization via sow vaccination. Direct oral immunization was tested in 382 suckling piglets. 190 animals were vaccinated, 192 animals received placebo. Neither the pentavalent vaccine nor a monovalent vaccine obtained from an epizootie strain of this stock gave protection in terms of a decrease in the duration of disease or a reduction of morbidity and mortality. Direct oral-immunization of suckling piglets thus was ineffective. Indirect immunization of the suckling piglets via vaccination of sow was performed in 189 pregnant sows 18--15 days before farrowing. 84 sows received vaccines i.m., 105 were given placebo i.m. These sows farrowed 1717 pigs, 777 of which were immunized indirectly and 940 treated with placebos. With the pentavalent vaccine and with the monovalent vaccine obtained from an epizootic strain we achieved significant protection of the indirect vaccinated suckling piglets.

D004926 Escherichia coli A species of gram-negative, facultatively anaerobic, rod-shaped bacteria (GRAM-NEGATIVE FACULTATIVELY ANAEROBIC RODS) commonly found in the lower part of the intestine of warm-blooded animals. It is usually nonpathogenic, but some strains are known to produce DIARRHEA and pyogenic infections. Pathogenic strains (virotypes) are classified by their specific pathogenic mechanisms such as toxins (ENTEROTOXIGENIC ESCHERICHIA COLI), etc. Alkalescens-Dispar Group,Bacillus coli,Bacterium coli,Bacterium coli commune,Diffusely Adherent Escherichia coli,E coli,EAggEC,Enteroaggregative Escherichia coli,Enterococcus coli,Diffusely Adherent E. coli,Enteroaggregative E. coli,Enteroinvasive E. coli,Enteroinvasive Escherichia coli
