Description
Wood chest with latched, hinged lid. Paper label on top of lid. Additional paper label with list of contents of kit adhered to inside of chest lid. Chest contains: one 30 cc. bottle of Physiological Salt Solution, one 30 cc. bottle of Suspension of Sterilized Culture of Typhoid Bacillus, one 10 cc. dropping flask for Typhoid Culture with rubber bulb attached, one 10 cc. dropping flask for Salt Solution with rubber bulb attached, five graduated test tubes (one missing from original count) , one metal test tube holder (which holds six test tubes), three glass droppers (one has rubber bulb attached); one cardboard box with nine small capillary tubes for collecting serum, one needle in glass capillary tube, extra rubber bulbs and rubber stopper. Kit also contains one paper booklet with directions. One newspaper clipping - "Easy Method of Doing Widal's Reaction for Typhoid" / "Early Closure of War Wounds" - ca 1916, found in kit.
In 1896, French physician and bacteriologist Georges Fernand Isidore Widal introduced a blood test for typhoid that still bears his name. Scientists had observed that cholera bacteria would clump together when injected into animals that had been immunized against the disease. This clumping, called agglutination, resulted from the binding of antibodies in the blood serum to the bacterial antigens. The clumps were easily observed through a microscope. Widal devised a practical diagnostic technique for typhoid based on this phenomenon. He mixed a small sample of the patient’s blood serum with a suspension of typhoid bacilli, then used a microscope to examine a drop of the solution. If the cells clumped together, the patient had typhoid antibodies, which indicated either current infection or prior exposure to the disease.
In 1905, bacteriologist John Borden modified the Widal test in a way that freed practicing physicians from their reliance on the services of bacteriological laboratories. By 1912, the Mulford company was advertising a complete test outfit based on his modifications. The kit included a needle and glass capillary tubes for collecting blood from the earlobe, a bottle of salt solution for diluting the sample, a bottle of killed typhoid bacilli suspension, dropper bottles, test tubes, and a rack. The test required no microscope, as the bacterial clumping was visible to the naked eye, appearing as a small white mass at the bottom of the test tube.
