Table 1 Distribution of patients with acute and chronic Q fever that showed specific autoantibodies (IgG isotype) by indirect immunofluorescence.

From: Autoantibody profiles in the sera of patients with Q fever: characterization of antigens by immunofluorescence, immunoblot and sequence analysis

Specific autoantibodies Acute Q fever (n = 24)(%) Chronic Q fever (n = 34)(%)
ANA 3(12.5) 5(14.7)
dsDNA 1(4.1) 3(8.8)
ANCA 3(12.5) 4(11.8)
ASMA 7(29.2)* 9(26.5)*
PCA 0 3(8.8)
CMA 3(12.1)* 13(38.3)#
Total positive patients 13(54.2) 23(67.6)
  1. ANA: Anti-nuclear antibodies;
