White blood cells per milliliter in liquefied sputum were counted in a hemocytometer. These gram-positive , sphere-shaped (coccal) bacteria (see figure How Bacteria Shape Up ) often cause skin infections but can cause pneumonia, heart valve infections, and bone infections and may be resistant to treatment with some antibiotics. This is a soft, narrow tube with a light and magnifying glass on the end. 2nd Ed. Of 163 patients whose sputum Gram stain met initial inclusion criteria, 43 were excluded for the following reasons: the official reading of the chest x-ray or a subsequent computed tomography did not confirm the presence of a pulmonary infiltrate (22 cases); antibiotics had been given for >16 hours (9); sputum was judged inadequate (8); and infection was thought not to be present (pulmonary edema in 3, diffuse alveolar hemorrhage in 1).

Intense prospective studies using conventional microbiologic techniques and viral polymerase chain reaction (PCR) have failed to establish an etiologic diagnosis in approximately one half of cases of community-acquired pneumonia (CAP) [15]. Sputum culture on blood agar showed scant growth in first quadrant only. Correlation of nasopharyngeal cultures with results of tympanocentesis culture is poor and lacks predictive value in identification of the causative agent of otitis media. Polymerase chain reaction on a nasopharyngeal swab was positive for influenza A virus. Organisms identified by MALDI-TOF as S mitis (oralis), alone or together with other NRF, predominated (14 of 31 [45.2%] cases; Figure 2A); the median cfu/mL of these streptococci was 5106.
