Relationship between polymorphonuclear leukocyte count in bronchoalveolar lavage fluid and bacterial content in Gram's stain and bacterial content in final microbiological report.

Eighty samples of bronchoalveolar lavage fluid (BALF) were obtained from the total of 48 patients (22 females and 26 males) and analyzed. Eighteen of those patients were organ transplant recipients. The relationship between polymorphonuclear leukocyte (PMN) count in direct sample and semi quantitative Gram-positive and Gram-negative bacterial content were analyzed in BALF samples.
