Trypanosome and Plasmodium are both found in blood. How do they differ in their locations relative to red blood cells?
To write:
The difference in the locations of Trypanosoma and Plasmodium relative to red blood cells.
Introduction:
Trypanosoma is a monophyletic group of unicellular parasitic flagellate protozoa. It is a part of phylum Sarcomastigophora. Plasmodium is a group of unicellular eukaryotes that are obligate parasites of vertebrates and insects and it injects during a blood meal. It is a part of the phylum Apicomplexa.
Explanation of Solution
Trypanosoma and Plasmodium both are found in the blood. Trypanosoma lives in the blood plasma or lymph node fluid. Trypanosoma is an extracellular parasite that causes sleeping sickness and other chronic infections. It occurs in two main niches, early in infection, they populate the blood and later they breach the blood-brain barrier.
Plasmodium lives inside the red blood cells. Plasmodium involves development in the blood-feeding insect host which injects parasite into the vertebrate host during a blood meal. Parasites grow within the tissue body of the vertebrate, before entering the bloodstream to infect the red blood cells. It causes malarial infection.
Thus, Trypanosoma is found in the plasma or lymph node of the blood while Plasmodium is found inside the red blood cells of the blood.

- One major difference in the envelope structure between gram positive bacteria and gram-negative bacteria is the presence or absence of a cytoplasmic membrane. True or false?arrow_forwardMycoplasmas are bacteria that lack cell walls. On the basis of this structural feature, which statement concerning mycoplasmas should be true? They are gram-negative. They are subject to lysis in hypotonic conditions. They lack a cell membrane as well. They should contain less cellulose than do bacteria that possess cell walls. They possess typical prokaryotic flagella.arrow_forwardI am doing my microbiology homework and I need help with these questions: 1) List the structures ALL bacteria possess. 2) Identify three structures SOME but not all bacteria possess. 5) Describe the structure and function of three different structures found outside of the bacterial cytoplasmic membrane. 6) Differentiate between the two main types of bacterial envelope structures. 7) Why are Gram-positive cell walls stronger than Gram-negative cell walls? 8) Name a substance in the envelope of SOME bacteria that can cause severe symptoms in humans. 9) Describe the causes of sporogenesis and germination 10) Compare and contrast the major features of archaea, bacteria and eukaryotes by completing the table below.
