a
Abbreviations: BP, B. pertussis; CP, C. pneumoniae; LM, L. micdadei; LP, L. pneumophila; MP, M. pneumoniae.
b
The spiked concentrations of all organisms were based on the numbers of dilutions for all organisms except C. pneumoniae; for which the concentrations are TCID50s per milliliter.
c
ODs at A450 were determined on a spectrophotometer.
