One disease NOT caused directly by bacteria is

Explanation

There are different types of microorganisms that can cause diseases in humans. One of these types is bacteria. However, there are some diseases that are not caused directly by bacteria. The question is asking us to identify one of these diseases from the given options. Option A is malaria, which is a parasitic disease caused by the Plasmodium parasite. This means that malaria is not caused directly by bacteria, but by another type of microorganism called a parasite. Malaria is transmitted through the bites of infected female Anopheles mosquitoes and can cause symptoms such as fever, chills, headache, and muscle pain. Option B is tuberculosis, which is a bacterial disease caused by the Mycobacterium tuberculosis bacterium. Therefore, this option is not the correct answer to the question. Option C is pneumonia, which is an infection of the lungs that can be caused by different types of microorganisms, including bacteria, viruses, and fungi. While some cases of pneumonia are caused by bacteria, not all cases are. Therefore, this option could be a possible answer to the question. Option D is tetanus, which is a bacterial disease caused by the Clostridium tetani bacterium. Therefore, this option is not the correct answer to the question. Option E is cholera, which is a bacterial disease caused by the Vibrio cholerae bacterium. This means that cholera is caused directly by bacteria and is not the answer to the question. In summary, the correct answer to the question is Option A, malaria, because it is a parasitic disease and not caused directly by bacteria. It is important to note that there are different types of microorganisms that can cause diseases in humans, including bacteria, viruses, fungi, and parasites.
