A) Malaria, mumps, polio
B) Cholera, typhoid, mumps
C) Tetanus, TB, malaria
D) Diphtheria, leprosy, plague

Answer 1

Hint: Bacterial diseases are caused by bacteria. Bacteria cause disease by emitting toxins, by internal toxins production, which is let out when the bacteria fragmented, or by making sensitivity to their antigenic properties. Bacteria serve as the major pathogen of both plant and animal diseases.

Complete answer:
Diphtheria is a bacterial infection that contaminates the mucous membranes of our nose and throat. Diphtheria is due to the bacterium named Corynebacterium diphtheriae. Leprosy is also a bacterial disease. It is a chronic infection. And it is caused by the bacteria Mycobacterium leprae. Plague is one of the epidemics and also a bacterial disease. It is caused by Yersinia pestis. so option ( D ) is the correct answer.s
       A) Malaria, mumps, polio -. Malaria is a mosquito based infectious disease of humans and other animals. It is caused by parasitic protozoans. And the mumps is a serious transferable infection, which is spread by a paramyxovirus. Polio is also a transmissible disease caused by the poliovirus. So all diseases of the above set are not the bacterial disease. So it is the wrong option.
B) Cholera, typhoid, mumps - Cholera is a transmissible disease, which is caused by the bacteria called Vibrio cholerae. Typhoid is a bacterial infection, it is caused by the bacteria Salmonella typhi. And mumps is a viral infection. So it is the wrong option.
C) Tetanus, TB, Malaria - Tetanus is a dangerous disease caused by a bacterial toxin, which affects our nervous system. And TB (Tuberculosis) is a transmissible bacterial disease. It is caused by Mycobacterium tuberculosis, which commonly affects the lungs. So it is the incorrect set of bacterial diseases.

So, The correct answer is “ D “- Diphtheria, leprosy, plague.

Note: Bacteria are one of the most dominant pathogens. They are found everywhere. The diseases caused by bacteria can be generally cured by the administration of certain antibiotics. All the bacteria are not pathogenic, some are beneficial for mankind also.
The viral diseases like mumps, common cold, etc. are not cured by the use of antibiotics.
