False-positive Widal tests have also been reported for patients with non-enteric salmonella infection, for example, Prior use of antibiotics can dampen antibody response giving a low titer in the Widal test even in the face of bacteriologically confirmed typhoid fever resulting in misdiagnosis. A single Widal test in an unvaccinated Ethiopian patient showing H and/or O titres greater than or equal to 1:160 and typhoid-like symptoms is strongly suggestive of typhoid fever.

If no other tests (either bacteriologic culture or more specific serology) are available, a fourfold increase in the titer (e.g., from 1:40 to 1:640) in the course of the infection, or a conversion from an IgM reaction to an IgG reaction of at least the same titer, would be consistent with a typhoid infection. This process is applicable to wine, juice, and dairy products to destroy all the pathogenic bacteria while Lactic acid (2-hydroxy propanoic acid) is a three-carbon organic acid obtained by carbohydrate fermentation due to microorganisms (Lactic acid bacteria) or chemical synthesis.
