MEDICALLY IMPORTANT PHYLA OF PROTOZOA We will study only those groups that contain pathogens.  1. Archaezoa--eukaryocytes that lack mitochondria. Many of these live in symbiosis in the  digestive tracts of animals. Most have two or more flagella for movement. Some have a  membrane attached to the flagella, called an undulating membrane. a.  Trichomonas vaginalis --lives in the vagina or the male urinary tract. Trichomoniasis is a  sexually transmitted disease, although it can also sometimes spread other ways. This organism  does not form cysts.  b.  Giardia lamblia-- lives in the small intestine of humans and other mammals. Cysts can survive  in the environment.  2. Microspora--obligate intracellular parasites that lack mitochondria and microtubules. Cause  chronic diarrhea and keratoconjunctivitis, often in AIDS patients.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
