Specific IgG antibody levels against different birds in the study population. A Pigeon; B Small parrot; C Parrot; D Parakeet and E Duck. Dotted line in each graph indicates the cut-off previously established in our laboratory for each antigen using a cohort of 30 healthy subjects. The cut-offs for pigeon, small parrot, parrot, parakeet and duck were 0.284, 0.193, 0.294, 0.348 and 0.508 OD450nm respectively. The percentage indicates the positivity of the group for each antigen.
