The correct answer is Vibrio cholerae. Explanation: ACommunicable Disease is an infectious disease that is transmissible by contact with infected individuals or their bodily discharges or fluids (as respiratory droplets, blood, or semen), by contact with contaminated surfaces or objects, by ingestion of contaminated food or water, or by direct or indirect contact with disease vectors (as mosquitoes, fleas, or mice). Cholera is a communicable disease characterized by intense vomiting and profuse watery diarrhea and that rapidly leases to dehydration and often death. Cholera is caused by infection with the bacteriaVibrio Cholera , which may be transmitted via infected fecal matter, food, or water. Cholera is an acute, diarrheal illness caused by infection of the intestine with the toxigenic bacterium. The infection is often mild or without symptoms, but can sometimes be severe. NOTE: Mycobacterium Leprae is a bacterium that causes leprosy, also known as 'Hansen’s disease', which is a chronic infectious disease that damages the peripheral nerves and targets the skin, eyes, nose, and muscles. Leprosy can occur at all ages from infancy to elderly but is curable in which treatments can avert disabilities. Tuberculosis (TB) is caused by a bacterium called Mycobacterium Tuberculosis . The bacteria usually attack the lungs, but TB bacteria can attack any part of the body such as the kidney, spine, and brain. Not everyone infected with TB bacteria becomes sick. As a result, two TB-related conditions exist latent TB infection (LTBI) and TB disease. Tetanusis an infection caused by bacteria called Clostridium Tetani . When the bacteria invade the body, they produce a poison (toxin) that causes painful muscle contractions. Another name for tetanus is “lockjaw”. Therefore, from the above points, it can be inferred that the communicable disease Cholera is caused by the bacteria Vibrio Cholera.
