Question 1 of 5
Bacterial infections of the female reproductive system include:
Correct Answer: A
Rationale: Rationale: 1. Vaginitis is a common bacterial infection in the female reproductive system. 2. Toxic shock syndrome can be caused by certain bacterial infections. 3. Endometritis is inflammation of the endometrium often due to bacterial infections. 4. Salpingitis is inflammation of the fallopian tubes, commonly caused by bacteria. Summary: - Choice B: Nephritis is a kidney infection, not related to female reproductive system infections. - Choice C: Nephritis and cystitis are not specific to the female reproductive system. - Choice D: Cystitis is a bladder infection, not typically considered part of female reproductive system infections.
Question 2 of 5
Group II category diseases as established by the NIAID include:
Correct Answer: D
Rationale: The correct answer is D: reemerging diseases. Group II category diseases by the NIAID are those that have reemerged or have the potential to reemerge. This classification helps prioritize research and resources. Choice A is incorrect because new foodborne pathogens fall under different categories. Choice B is incorrect as eradicated diseases are not part of the reemerging group. Choice C is incorrect because bioterrorism agents are classified separately. Therefore, the correct answer is D as it aligns with the purpose of Group II category diseases.
Question 3 of 5
Which of the following consists of DNA viruses?
Correct Answer: A
Rationale: The correct answer is A: Parvoviridae. Parvoviruses are DNA viruses, as their genetic material is composed of DNA. This distinguishes them from RNA viruses like Picornaviridae, Astroviridae, and Togaviridae. Parvoviruses replicate in the host cell nucleus, further confirming their DNA nature. Therefore, based on their DNA composition and replication process, Parvoviridae is the correct choice.
Question 4 of 5
The food preparation process in which not all microorganisms are killed, but the number of microbes capable of spoiling the food or causing disease is reduced, is called
Correct Answer: B
Rationale: The correct answer is B: pasteurization. This process involves heating food to a specific temperature to kill harmful bacteria while preserving the flavor and quality of the food. Sanitation (A) refers to maintaining cleanliness to prevent contamination. Disinfection (C) involves killing most, but not all, microbes on surfaces. Purification (D) typically refers to the process of removing impurities, not specifically targeting microbes. In this case, pasteurization best describes the process of reducing harmful microbes in food without completely eliminating all microorganisms.
Question 5 of 5
Study of bacteriological sputum specimens stained by the Ziel-Neelsen method revealed some bright-red acid-resistant bacilli that were found in groups or singularly. When inoculated onto the nutrient media, the signs of their growth show up on the 10-15 day. These bacteria relate to the following family:
Correct Answer: A
Rationale: The correct answer is A: Mycobacterium tuberculosis. 1. Bright-red acid-resistant bacilli indicate the presence of mycolic acids in the cell wall, characteristic of Mycobacterium species. 2. Found in groups or singularly suggests the clumping nature of acid-fast bacilli. 3. Growth appearing after 10-15 days on nutrient media is consistent with the slow growth rate of Mycobacterium tuberculosis. 4. Yersinia pseudotuberculosis (B) and Klebsiella rhinoscleromatis (D) are not acid-fast bacilli and do not match the growth characteristics described. 5. Histoplasma dubrosii (C) is a fungus, not a bacterium, and does not exhibit acid-fast staining or the described growth pattern.
