Trichomonas Vaginalis, a non-viral pathogen, causes widespread sexually transmitted disease. This parasite, anaerobic and flagellated protozoa is the most common cause of protozoan infections in wealthy countries. Vaginal infection continues to be a major cause. It can also infect both the prostate and urethra of male and female patients. T. vaginalis remains largely unaffected in men, although there are reports of discharge and dysuria.
The Microorganism: A Comprehensive Description
T. vaginalis, though a protozoon pyriforme, has been observed to exist. The organism measures approximately 9×7 m. There are four flagella visible in its front and one in its posterior sections. The life cycle is simple. Trophozoites can be transferred after coitus, without the need for a cyst. The current trophozoites experience significant division through binary fission. It results in large numbers in the urogenital tubes.
The organism may look different depending on its physiochemical environment. If the plant is placed in an axenic cultivation, it tends to maintain a uniform shape, like a pear, or an oval. The parasite takes on an ameboid shape when it is linked to the vaginal epithelial cells. The cytoskeleton is made up of tubulin fibers and actin. Like other eukaryotes the anterior location houses the nucleus. This is protected by a nuclear envelope. The axostyle starts at the nucleus. It runs lengthwise through the organism and ends at its posterior end. This structure acts as an anchor section for epithelial cell membranes. You can clearly see the organism’s granules with a light microscope. Catalase is not produced by the organism. The glycogen granules can be easily seen using an electron microscope.
Acridine orange staining is a superior method for viewing the organism under microscopes than wet staining. This approach can be used to diagnose and observe T. vaginalis if fluorescence microscopy has been made available.
Factors that influence virulence
The understanding of pathogenesis and the virulence characteristics has been a slow process for biologists. The pathogenesis process is fundamentally affected by adhesions. An examination of protozoa’s surface revealed many adhesion proteins. The parasite acquires a flat form and laminates itself to the mammalian host cells upon contact with the mammalian surface (Van Gerwen & Muzny, 2019). The parasite encourages mammalian cell cytotoxicity upon attachment. T. vaginalis releases chemicals to the target cells. These chemicals damage cell membranes and cause cytotoxicity. The chemicals can cause holes in the membranes of erythrocytes. They also produce lytic substances that destroy nucleated cells.
Immunity
The immune system is both adaptive and innate in Trichomoniasis. To avoid the parasite immune reaction, it is important to activate the purinergic signaling pathway. The female reproductive health system is an important immune site that protects the body from pathogen invasion (Masha and al., 2019,).
