ABSTRACT
Infections because of multidrug-resistant (MDR) organisms are a bur-
geoning problem in the treatment of increasingly complex medical
patients. Respiratory infections caused by methicillin-resistant Staphylo-
coccus aureus (MRSA) are especially challenging. Whether acquired from
the community or nosocomially, these highly adaptable bacteria possess
distinctive genes for antibiotic resistance and toxins that present significant
obstacles to effective care.
