True about HIV, Osteomyelitis is all except -
Osteomyelitis in AIDS

Osteomyelitis, which rarely develops in patients with AIDS, is monomicrobial in 50 percent of patients and polymicrobial in 35 percent with the remaining showing no organism.
Staphylococcus is the most common organism.
Interestingly, osteomyelitis due opportunistic organism is unusual, suggesting that HIV infection does not alter the fundamental pathophysiology of osteomyelitis that favours, in most circumstances, S. aureus.
As pathophysiology of osteomyelitis is not altered, all the pathological changes seen in other osteomyelitis are seen in AIDS also.
