Questions and Answers
A patient presents with a localized infection in the nasal cavity. Which of the following organisms is MOST likely contributing to the infection, assuming it originates from the patient's normal flora?
A patient presents with a localized infection in the nasal cavity. Which of the following organisms is MOST likely contributing to the infection, assuming it originates from the patient's normal flora?
- Kingella species
- Staphylococcus aureus (correct)
- Candida albicans
- Eikenella corrodens
Following an upper respiratory tract infection, a patient develops a secondary infection. A culture reveals the presence of Peptococcus species. Where was the MOST likely location of the primary infection that allowed for the overgrowth of this bacteria?
Following an upper respiratory tract infection, a patient develops a secondary infection. A culture reveals the presence of Peptococcus species. Where was the MOST likely location of the primary infection that allowed for the overgrowth of this bacteria?
- Nasopharynx
- Pharynx
- Upper respiratory tract (correct)
- Nose
A patient is diagnosed with a pharyngeal infection, and the culture indicates the presence of both Candida albicans and Hemophilus parainfluenzae. What can be concluded about the patient's condition?
A patient is diagnosed with a pharyngeal infection, and the culture indicates the presence of both Candida albicans and Hemophilus parainfluenzae. What can be concluded about the patient's condition?
- Both organisms are part of the normal flora of the pharynx and may or may not be the cause of the infection. (correct)
- The patient likely contracted the infection from an external source rather than their own flora.
- The presence of both organisms is unusual and suggests a compromised immune system.
- The patient has a rare co-infection that requires aggressive treatment.
A researcher is studying the distribution of normal flora in the respiratory tract. They collect samples from the nasopharynx of healthy individuals. Which combination of organisms would the researcher MOST likely expect to find?

A patient undergoing treatment with broad-spectrum antibiotics develops a respiratory infection. The infection is traced to an overgrowth of a bacterium typically found in the general distribution of the upper respiratory tract. Which of the following organisms is MOST likely responsible for the infection?
