Match the following pathogens with their descriptions: Helminths
- A. One-celled microorganisms classified by their shapes
- B. May be made up of one or more cells; enter the human body through cuts or cracks in the skin
- C. Rod-shaped bacteria that appear in chains
- D. Type of bacteria often spread through vectors
- E. Tiny parasites that live within cells of hosts and reproduce there
- F. Parasitic worms that can inhabit the digestive tract of humans
- G. Single-celled animals that live in water and cause intestinal illnesses when ingested
Correct Answer: F
Rationale: Helminths are parasitic worms, such as tapeworms or roundworms, that often inhabit the human digestive tract.
Match the following pathogens with their descriptions: Protozoa
- A. One-celled microorganisms classified by their shapes
- B. May be made up of one or more cells; enter the human body through cuts or cracks in the skin
- C. Rod-shaped bacteria that appear in chains
- D. Type of bacteria often spread through vectors
- E. Tiny parasites that live within cells of hosts and reproduce there
- F. Parasitic worms that can inhabit the digestive tract of humans
- G. Single-celled animals that live in water and cause intestinal illnesses when ingested
Correct Answer: G
Rationale: Protozoa are single-celled organisms that can cause intestinal illnesses, such as those from contaminated water (e.g., Giardia).
Match the following pathogens with their descriptions: Rickettsia
- A. One-celled microorganisms classified by their shapes
- B. May be made up of one or more cells; enter the human body through cuts or cracks in the skin
- C. Rod-shaped bacteria that appear in chains
- D. Type of bacteria often spread through vectors
- E. Tiny parasites that live within cells of hosts and reproduce there
- F. Parasitic worms that can inhabit the digestive tract of humans
- G. Single-celled animals that live in water and cause intestinal illnesses when ingested
Correct Answer: D
Rationale: Rickettsia are bacteria often transmitted by vectors like ticks or fleas, as seen in diseases like Rocky Mountain spotted fever.
Types of bacteria include
- A. Helminths and fungi.
- B. Cocci, bacilli, and spirilla.
- C. Rickettsia.
- D. Vectors and protozoa.
Correct Answer: B
Rationale: Bacteria are classified by shape, including cocci (spherical), bacilli (rod-shaped), and spirilla (spiral). Rickettsia is a specific genus of bacteria, not a shape category. Helminths, fungi, vectors, and protozoa are not bacteria.
