Specific and Nonspecific immunity to Serratia marcescens infection. 1976

M S Simberkoff, and N H Moldover, and J J Rahal

By specific active or passive immunization, mice were protected against lethal infection with Serratia marcescens. Animals that were immunized against organisms of the challenge strain O serotype survived, whereas animals that were immunized against other serratia O serotypes did not survive. Protective sera (from convalescent partients or immunized rabbits) contained a specific complement-independent opsonin. These sera also contained passive hemagglutinating and bacterial agglutinating antibodies in high titer. The protective and complement-independent opsonizing antibodies were associated with IgG fractions of the serum, while the agglutinating antibodies were primarily associated with the IgM. Mice also survived infection with Serratia after immunization against the Re595 Salmonella minnesota mutant. However, complement-independent opsonizing antibody was not demonstrated in these cross-protective sera.

D007114 Immunization Deliberate stimulation of the host's immune response. ACTIVE IMMUNIZATION involves administration of ANTIGENS or IMMUNOLOGIC ADJUVANTS. PASSIVE IMMUNIZATION involves administration of IMMUNE SERA or LYMPHOCYTES or their extracts (e.g., transfer factor, immune RNA) or transplantation of immunocompetent cell producing tissue (thymus or bone marrow).

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
