(b) Transtracheal aspirate or direct lung aspirate of pulmonary sources
(c) Culdocentesis and possibly double-lumen-protected swabs of endometrial contents.
(d) Suprapubic aspiration of urine
(e) Biopsies of normally sterile tissue
Specimens that are unacceptable
(a) Pus from superficial or open wounds (includes decubiti, other ulcers)
(b) Lower genital tract in women and urethra in both sexes
(c) Pharyngeal, oral, nasal, dental, eye, ear, sputum, nasotracheal aspiration cultures
