Inflammatory cell density of bronchoalveolar lavage fluid from mice infected with MRSA with or without Pi Sup.

	Cell density × 104 cells/ml, mean ± SEM (n = 6–8)
Cell type	MRSA	MRSA + Pi Sup	Pi Sup	Broth
Overall	59.2 ± 8.7	46.1 ± 12.9	40.5 ± 6.4	63.4 ± 12.0
Neutrophils	20.7 ± 5.2b	16.7 ± 8.7b	2.6 ± 1.4a,b	0.13 ± 0.07
Macrophages	38.4 ± 5.8	29.3 ± 4.8	37.4 ± 5.9	63.0 ± 11.9
Lymphocytes	0.18 ± 0.07	0.08 ± 0.04	0.46 ± 0.19	0.25 ± 0.08

Data are representative of 6–8 replicates. MRSA, methicillin-resistant Staphylococcus aureus; Pi Sup, supernatant of P. intermedia.

^ap < 0.05 vs. MRSA-infected mice group.

^bp < 0.05 vs. untreated mice group. Similar results were obtained from two independent experiments.
