Question

Which is carcinogen and pathogen?
a) Mycobacterium
b) LAV (Lymphadenopathy Associated Virus)
c) Hepatitis-A virus
d) Cancer bacteria virus

Answer 1

Hint A carcinogen is a cancer-causing agent. It is present in the inactive form and gets activated due to some signals. A pathogen is a virus or a bacterium that has the capability to cause disease in humans.

Complete answer: The virus or bacteria which is capable of causing a certain disease and cancer in humans is known as the pathogenic carcinogen. Lymphadenopathy Associated Virus is the name of the human immunodeficiency virus (HIV) that causes AIDS. It also causes Kaposi sarcoma which causes skin lesions to form on the soft tissues. This type of cancer is only caused by the patients whose immune system is compromised due to HIV-AIDS. Kaposi sarcoma causes lesions that grow on the skin, lymph nodes, internal nodes, and on the lining of the mouth, nose, and throat.

Additional information: Mycobacterium is the pathogen that causes tuberculosis in human beings. The symptoms of tuberculosis include cough and sudden weight loss. The pathogen is transmitted through the coughing of an infected person to the healthy person from the air droplets. It mainly infects the lungs of the infected person. The hepatitis A virus is the virus that causes hepatitis A infection in human beings. It is a contagious liver infection. The symptoms include fatigue, nausea, pain in the abdomen and loss of appetite. The cancer bacteria virus is the virus that causes cancer and is a carcinogen.

So, the answer is ‘LAV (Lymphadenopathy Associated Virus)’.

Note: The person who gets infected by the LAV virus usually develops AIDS and then has a greater chance of getting cancer. Kaposi sarcoma cancer is only caused by the person who is infected with the HIV virus and has an immune deficiency.
