The development and evaluation of immunodiffusion, immunofluorescence and physiological tests for the differentiation of atypical trichophyton rubrum and T. mentagrophytes isolates

  • Wallace E. Turner
  • William Kaplan


Five laboratory procedures: 1) immunodiffusion, 2) immunofluorescence, 3) in vitro hair perforation, 4) pigment stimulation, and 5) a urease test were compared for their ability to differentiateT. rubrum fromT. mentagrophytes. Of the physiological tests, thein vitro hair perforation technique was the most reliable for differentiating the two species. With the serological tests, the organisms were not differentiated by immunodiffusion, but if appropriate dilutions of the conjugates were used in immunofluorescence testing, most isolates could be differentiated.
