Studies on Hemagglutination and Hemolysis by Escherichia Coli Antisera
A study on hemagglutination and hemolysis by Escherichia coli O111 and O55 (rabbit) antisera and on hemagglutination and hemolysis inhibition by E. coli O111 and O55 antigens revealed the following facts. 1. Red blood cells of man, dog, rabbit, guinea pig, sheep, rat, and chicken adsorb E. coli O111 and O55 antigens and thus become specifically agglutinable by the homologous E. coli antisera. 2...
متن کاملHemagglutination by purified type I Escherichia coli pili
Many enterobacteria can cause agglutination of erythrocytes, but previous investigations have not proven which components of the bacteria are responsible. We used a strain of Escherichia coli K12 which causes mannose-sensitive hemagglutination (HA) of guinea pig cells. Common pili were purified from these bacteria by shearing them from the bacteria followed by selective precipitation in acid an...
متن کاملHemagglutination by Escherichia coli in septicemia and urinary tract infections.
The agglutination of erythrocytes from various animal species by Escherichia coli was studied. The 405 strains of E. coli were isolated from urine in patients with urinary tract infections, from blood in septicemic patients, or from feces in persons without intestinal or urinary disorders. In urinary tract infections, d-mannose-resistant agglutination (MRHA) of human erythrocytes was the most c...
متن کاملSerological Studies of O Antigens of Escherichia Coli by Means of the Hemagglutination Test.
Kunin, Calvin M. (University of Virginia, Charlottesville) and Mary V. Beard. Serological studies of O antigens of Escherichia coli by means of the hemagglutination test. J. Bacteriol. 85:541-548. 1963.-The serological interrelationships among most of the known O antigens of Escherichia coli were studied by the hemagglutination test. Good agreement with the bacterial agglutination test was foun...
متن کاملEffects of subminimal inhibitory concentrations of ampicillin on hemagglutination of Escherichia coli.
The hemagglutination (HA) activity of Escherichia coli was enhanced by subminimal inhibitory concentrations (sub-MICs) of ampicillin. One half of the MIC of ampicillin caused a bacterial filamentation and diminished bacterial piliation (as observed by light and electron microscopies) as well as an increase of HA activity. HA activity, however, decreased after separation of ampicillin-treated ba...
