Which bacteria is commonly associated with bone/joint infections?

Staphylococcus aureus
Viridans group Streptococci
Neisseria meningitidis
Listeria

The correct answer is: Staphylococcus aureus

Staphylococcus aureus is the correct answer because it is the most common bacteria associated with bone and joint infections. Staphylococcus aureus has a high affinity for bone and joint tissues, making it a frequent culprit in osteomyelitis (bone infection) and septic arthritis (joint infection). It is known for its ability to cause a variety of infections due to its virulence factors, including the production of toxins and enzymes that facilitate tissue damage and spread within the body. The other options are incorrect: - Viridans group Streptococci are more commonly associated with dental infections and subacute bacterial endocarditis. - Neisseria meningitidis is known for causing meningitis and septicemia, but not commonly associated with bone and joint infections. - Listeria is more commonly associated with foodborne infections and infections in immunocompromised individuals, rather than bone and joint infections.
