Answer: Rhino viruses.
- A Salmonella typhi
- B Trichophyton species
- C Vibrio cholerae
- D Rhino viruses
Correct answer: D. Rhino viruses
Explanation: The common cold is caused by rhino viruses, which infect the nose and respiratory passage but not the lungs. It is marked by nasal congestion, sore throat and cough.
The Plasmodium parasite needs both hosts: the female Anopheles mosquito injects sporozoites while biting (infecting the human liver and RBCs, causing the malaria fever cycle), then picks up gametocytes from an infected person's blood, completing the parasite's sexual stage inside the mosquito.
