. Applied bacteriology for nurses. Fig. 23.—Typhoid bacilli unagglutinated (Jordan). means of the hanging-drop method under the micro-scope. If complete agglutination takes place within. Fig. 24.—Typhoid bacilli partially agglutinated (Jordan). twenty to thirty minutes, one speaks of having obtaineda positive Widal reaction. This means that the patient IMMUNITY 73 is suffering from typhoid fever or has recently had thedisease, for the serum continues to show the reaction forsome time after convalescence. Agglutination reactions may also be employed in areverse manner for identifying bacteria.

This means that the patient IMMUNITY 73 is suffering from typhoid fever or has recently had thedisease, for the serum continues to show the reaction forsome time after convalescence. Agglutination reactions may also be employed in areverse manner for identifying bacteria. In that case,one employs an agglutinating serum made against acertain bacterium and tests the bacterium one is study-ing. If it agglutinates with this serum, one argues thatit is identical with, or at least very closely related to,the bacterium used for making the serum.
