Disease Causative Agents

Common cold and influenza (flu) are both caused by viruses, specifically rhinoviruses and influenza viruses respectively. Bacteria cause different types of infections like strep throat or tuberculosis, fungi cause conditions like yeast infections, and algae are plant-like organisms not involved in human respiratory infections.

Ranikhet disease, also known as Newcastle disease, is a highly contagious viral disease specifically affecting poultry. Anthrax affects multiple species including humans, Foot and Mouth disease affects cloven-hoofed animals like cattle and pigs, and Pebrine is a disease of silkworms.

Hepatitis A, typhoid, and cholera are all waterborne diseases transmitted through contaminated water. Measles is an airborne disease spread through respiratory droplets and is not caused by water contamination.

Typhoid, tuberculosis, and cholera are all bacterial diseases caused by Salmonella typhi, Mycobacterium tuberculosis, and Vibrio cholerae respectively. Dengue fever is a viral disease caused by the dengue virus transmitted by Aedes mosquitoes, making it the only non-bacterial option listed.

MASA syndrome, is a rare X-linked recessive neurological disorder. It is caused by mutations in the L1CAM gene.

The membrane attack complex containing C8 and C9 is important for destroying the Neisseria bacterium.

Exotic ungulate encephalopathy is a transmissible spongiform encephalopathy (TSE), or prion disease, identified in infected organs of zoo animals.

In this group, some or all of the genes are translated into protein from an RNA strand complementary to that of the genome (as packaged in the virus particle). There are some plant viruses in this group and it also includes the viruses that cause measles, influenza and rabies.

This is not thought to be due to an infection but a relatively benign form of leukaemia in the elderly.

This is contracted by wrestlers. It apparently spreads by direct contact from skin lesions on one wrestler to his/her opponent, and usually appears in the head and neck region (which are frequently sites of contact in wrestling holds).

Celery mosaic, like most potyviruses, is non-persistently transmitted by aphids. This means that the aphid can pick up the virus on its stylet (its mouthparts) and transfer it quickly to the next plant it probes. The virus can also be transmitted mechanically by tools and machinery. There is no evidence of seed transmission.

Mumps is infection and inflammation of parotid gland by paramyxovirus.

Jaundice, caused by Hepatitis A virus, is a water-borne disease and spreads mainly via sewage and contaminated food and water. Accumulation of bilirubin or its conjugates in body tissues causes jaundice. Hence, it is correct.

The disease caused by a virus is Measles.

It is correct.
