Summary

Monocercomonas spp. from snakes showed hemolytic activity against human and animal red blood cells. This protozoan parasite demonstrated a broad-spectrum hemolytic effect on various erythrocyte types.

Area of Science:

  • Parasitology
  • Hematology
  • Herpetology

Background:

  • Monocercomonas spp. are flagellated protozoan parasites.
  • The host organism, Tropidophis melanurus, is a species of snake.

Purpose of the Study:

  • To investigate the hemolytic activity of a Monocercomonas spp. isolate.
  • To determine the effect of this isolate on erythrocytes from different species.

Main Methods:

  • An isolate of Monocercomonas spp. was obtained from Tropidophis melanurus.
  • The isolate was incubated with human erythrocytes (groups A, B, AB, O).
  • The isolate was incubated with erythrocytes from six animal species: rabbit, rat, chicken, horse, bovine, and sheep.

Main Results:

Related Experiment Videos

  • Monocercomonas spp. exhibited hemolytic activity against all tested human erythrocyte groups.
  • The parasite isolate also showed hemolytic activity against erythrocytes from all six animal species tested.
  • This indicates a broad range of erythrocyte targets for the parasite's hemolytic factors.

    • Conclusions:

    • The Monocercomonas spp. isolate possesses significant hemolytic activity.
    • This activity is effective against a wide array of mammalian and avian erythrocytes.
    • Further research is warranted to identify the specific hemolytic factors produced by Monocercomonas spp.
