Final answer:
Sickle cell patients with osteomyelitis are at risk of infection with S. aureus, M. tuberculosis, Pseudomonas aeruginosa, and Streptococcus pyogenes. For bacteremia, they are at risk from Streptococcus pneumoniae, Haemophilus influenzae, and Salmonella species.
Step-by-step explanation:
Osteomyelitis:
Osteomyelitis is an inflammation of bone tissues caused by infection. Sickle cell patients are at increased risk of osteomyelitis, with the most common causative agent being S. aureus. However, other bacteria such as M. tuberculosis, Pseudomonas aeruginosa, and Streptococcus pyogenes can also cause osteomyelitis.
Bacteremia:
Sickle cell patients are at increased risk of bacteremia, which is the presence of bacteria in the blood. The most common bacteria causing bacteremia in these patients are Streptococcus pneumoniae, Haemophilus influenzae, and Salmonella species.
