Antipili antibody affords protection against experimental ascending pyelonephritis. 1979

F J Silverblatt, and L S Cohen

The ability of antipili antibody to prevent ascending urinary tract infection was investigated in rats. One group of rats was immunized passively with rabbit antisera to purified pili and challenged by intravesicular inoculation of 5 x 10(7) heavily piliated Escherichia coli. Only 2 of 14 immunized animals developed cortical abscesses as compared to 13 of 15 control rats given normal rabbit serum (P equals 0.0001). The mean log titer of bacteria in the kidneys of the immunized rats was 0.85 vs. 6.08 in the controls (P less than 0.005). A second group was actively immunized with pili. 3 of 16 immunized animals became infected as compared to 10 of 15 controls (P equals 0.01). The mean log titers were 2.13 and 4.54, respectively (P less than 0.01). A third group was passively immunized and challenged with a strain that had different O, K, and H antigens but shared pili antigens. Abscesses occurred in 4 of 15 immunized animals as compared to 13 of 15 controls (P equals 0.001). The mean log titers were 2.37 and 5.63, respectively (P less than 0.005). These results indicate that antipili antibody protects rats against ascending urinary tract infections.

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).

D011704	Pyelonephritis	Inflammation of the KIDNEY involving the renal parenchyma (the NEPHRONS); KIDNEY PELVIS; and KIDNEY CALICES. It is characterized by ABDOMINAL PAIN; FEVER; NAUSEA; VOMITING; and occasionally DIARRHEA.	Necrotizing Pyelonephritis,Pyelonephritis, Acute Necrotizing,Pyelonephritides
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
