Correlation Between Bacterial Phenotypes and In Vitro Neutrophil Antibacterial Responses in Univariable Analysis

PA Phenotypes	Phagocytosis		Intracellular Bacterial Killing
	Coefficient	P Value	Coefficient	P Value
Twitching	0.43	<.001	0.43	<.001
Swimming	0.07	.55	0.05	.69
Mucoidy	–0.19	.09	–0.26	.03
Congo red binding	0.18	.13	0.32	<.01

The association between each bacterial phenotype and neutrophil phagocytosis or intracellular bacterial killing was calculated using the Spearman correlation coefficient.
