A client presents with a localized infection characterized by pus formation and redness around the nail fold, specifically on their index finger. Which of the following bacterial shapes is most commonly associated with such localized, pus-forming infections?
- ASpirilla
- BCocci
- CBacilli
- DVibrio
Show answer & explanationAnswer & explanation
Correct answer: B. Cocci
Cocci are spherical bacteria that often grow in clusters or chains and are frequently responsible for localized, pus-forming infections such as staph infections, which commonly affect the nail folds.
Why the other options are wrong
- A. Spirilla are spiral-shaped bacteria and are not typically associated with localized pus-forming infections.
- C. Bacilli are rod-shaped bacteria; while they can cause infections, cocci are more commonly linked to pus-forming skin infections.
- D. Vibrio are comma-shaped bacteria, typically associated with gastrointestinal illnesses.
Cocci Bacteria
Spherical-shaped bacteria that can appear singly, in pairs, chains, or clusters, commonly causing localized, pus-forming infections.
- Spherical shape.
- Often cause staphylococcal and streptococcal infections.
- Associated with boils, abscesses, and pus formation.
Memory trick: Circles of Cocci cause concentrated collections of crud.
