Table 2 Significant Spearman Rank Correlations between the concentrations of BSA and LBP in blood serum and the respiratory score and general clinical score in calves with an experimentally induced respiratory Chlamydia psittaci infection (n = 39)

From: Acute phase proteins as local biomarkers of respiratory infection in calves

  1. BSA bovine serum albumin. LBP lipopolysaccharide binding protein. rsp: Coefficient of Spearman Rank Correlation. P: probability level. n = 39*: all time points after exposure were included in analysis, i.e. the acute phase of respiratory illness (4 dpi; n = 13), and the recovery phase (9 dpi; n = 13 and 14 dpi; n = 13)
