Bacterial Culture, Aerobic, Respiratory
Clinical Information: Common bacterial agents of acute pneumonia include: Streptococcus
pneumoniae, Staphylococcus aureus, Haemophilus influenzae, Pseudomonas aeruginosa, and members of
the Enterobacteriaceae (Escherichia coli, Klebsiella spp., and Enterobacter spp.) Clinical history, physical
examination, and chest X-ray are usually adequate for the diagnosis of pneumonia, and antimicrobial
treatment is typically based on these findings. Culture of expectorated sputum is used by some for the
evaluation of pneumonia, although controversy exists regarding this practice; both sensitivity and
specificity of sputum cultures are generally regarded as poor (100,000 cfu/mL of a urinary pathogen is indicative of
UTI. Isolation of 2 or more organisms >10,000 cfu/mL may suggest specimen contamination.

Bacterial Culture, Anaerobic
Clinical Information: Anaerobic bacteria are the greatest component of the human body's normal
bacterial flora colonizing the skin, oral cavity, and genitourinary and lower gastrointestinal tracts. Their
presence is important in preserving vitamin and other nutrient absorption and in preventing infection with
pathogenic bacteria. Anaerobes generally are of low pathogenicity but may possess virulence factors such
as endotoxin or polysaccharide capsules or produce extracellular toxins. Disease occurs when a large
inoculum develops in an area lacking oxygen and/or poor blood supply. Typical anaerobic infections
include periodontitis, abdominal or pelvic abscesses, endometritis, pelvic inflammatory disease, aspiration
pneumonia, empyema and lung abscesses, sinusitis, brain abscesses, gas gangrene, and other soft tissue
