Final Answer:
Some strains of Staphylococcus aureus can invade the body and cause diseases such as pneumonia and bacteremia, highlighting its pathogenic potential.
Step-by-step explanation:
Staphylococcus aureus, commonly known as staph, is a bacterium that can lead to various infections. Certain strains possess virulence factors that enable them to invade the body and cause diseases, including pneumonia (lung infection) and bacteremia (presence of bacteria in the bloodstream). Staphylococcus aureus is known for its versatility as a pathogen, and it can cause a range of infections, from minor skin conditions to severe, life-threatening diseases. Factors such as antibiotic resistance contribute to the challenges in treating infections caused by Staphylococcus aureus.
