 AB    The authors present the actual review on several publications concerning
       the molecular characterizations of the viruses found in parasitic
       protozoa such as Giardia, Trichomonas, Leishmania and Entamoeba
       histolytica. All of the RNA viruses observed in parasitic protozoa
       showed several similarities and did not considerably differ from the
       viruses found in simple eukaryotic cells; they closely correspond to
       dsRNA viruses of yeast. The supposition that the protozoan symbionts
       detected in laboratories transfer to their hosts in natural conditions
       seemed to be rational, though, there are no evidences that these
       symbionts are potential pathogens. However, the opinion reiterates that
       intestinal protozoa (e.g. Entamoeba histolytica) may serve as vectors
       for HIV or cofactors of HIV infection. The authors point out that
       irrespective of the potential role of viruses as vectors in the
       transfection system for parasitic protozoa, the observed viral system
       constitutes an unusual experimental system to solve the problems of gene
       expression.
