ORGANISM THAT EXHIBITS SATELLITISM ALONG WITH STAPH AUREUS:
- A- HAEMOPHILUS INFLUENZAE
- B- SHIGELLA SP.
- C- CLOSTIRIDIUM SP.
- D- S. PNEUMONIAE.
The organism that exhibits satelliteism along with Staphylococcus aureus is: A. Haemophilus influenzae
Here's why:
- Satelliteism:
In this phenomenon, a smaller organism benefits from the growth and metabolic byproducts of a larger organism, allowing it to grow closer to the larger organism and form distinct colonies.
- Staphylococcus aureus:
This is a common and versatile bacterium that can cause various infections.
- Haemophilus influenzae:
This bacterium requires specific growth factors like X and V, which are readily available around S. aureus colonies due to its metabolic activity. H. influenzae can then utilize these factors for its own growth, forming colonies close to S. aureus on an agar plate.
Therefore, Haemophilus influenzae is the organism that exhibits satelliteism along with Staphylococcus aureus.
Other Options:
Here's a breakdown of the other options:
B. Shigella sp.:
These bacteria are not known for satelliteism and are primarily associated with gastrointestinal infections.
C. Clostridium sp.:
Some Clostridium species are known for satelliteism, but their preferred partner organisms are different from S. aureus.
D. S. pneumoniae:
This bacterium also requires specific growth factors similar to H. influenzae, but it does not exhibit satelliteism with S. aureus.
