What is the most common pathogen found in cases of osteomyelitis?

Staphylococcus aureus is the most common pathogen associated with osteomyelitis. This bacterium is a coagulase-positive staphylococcus, and it is particularly known for its ability to cause a variety of infections, including skin infections, pneumonia, and, importantly, bone infections. In cases of osteomyelitis, Staphylococcus aureus often enters the bone through open fractures or surgical procedures, or it can spread from adjacent soft tissue or through the bloodstream. Because of its prevalence and virulence, it is crucial for healthcare providers to be aware of Staphylococcus aureus as a primary concern when diagnosing and treating osteomyelitis.

Other pathogens, while they can also cause osteomyelitis, are less frequently encountered. For example, Salmonella is somewhat associated with osteomyelitis, particularly in patients with sickle cell disease, but it does not rival Staphylococcus aureus in general cases. Streptococcus species can be involved in some infections, but they are not as common as Staphylococcus aureus for osteomyelitis. Mycobacterium, which can lead to osteomyelitis in specific circumstances such as tuberculosis, is also not a widespread cause compared to Staphylococcus aureus. Understanding
