Leukocyte agglomeration test to reveal bacterial infections in mice.
A simple and rapid procedure was used to detecting covert bacterial infections in mice. The procedure was based on observations that bacterial infections were associated with clumping of leukocytes. A large drop of citrated venous blood was placed on a slide and allowed to spread. After fixation and staining the percentage of agglomerated leukocytes was determined by counting. Experimental urinary tract infections caused by either Escherichia coli or Proteus mirabilis served as a model to test the efficacy of the method. Elevation of leukocyte agglomeration was observed in these localized infections.
