Case 176. Reference case 176A

       
  Immunostaining using a 1:1,000 diluted patient's own serum, identifying intracellular microbes in paraffin section (indirect immunoperoxidase).  
       

 

  The patient's serum was not cross-ractive with L. tropica in the presented case. Generally speaking, the specificity of the patient serum is high enough in case of protozoan or helminthic infection.
