MONSALVE, Santiago; MIRANDA, Jorge  and  MATTAR, Salim. First evidence of Chlamydophila psittaci circulation in Colombia: a possible public health risk. Rev. salud pública [online]. 2011, vol.13, n.2, pp.314-326. ISSN 0124-0064.

Objective To establish the seroprevalence of Chlamydophila psittaci in birds of Amazona spp genus and workers from some zoos and CAVâ (centers for attention and evaluation of wildlife) of Colombia. Methods We analyzed 138 sera from birds of the genus Amazona spp, 24 sera from other species of birds and 39 human sera by indirect ELISA. RMOMP was used as antigen (major outer membrane protein of Chlamydophila psittaci). For the conjugate of birds it was used an anti-turkey-chicken IgG labeled with biotin, for the human conjugate we used an anti-IgG labeled with peroxidase. Sera were diluted 1:100. Results Of the 138 sera from birds of the genus Amazona spp 118 (85 %) were seropositive. Regional seroprevalence was as follow: Caldas CAV Torre cuatro 36 (90 %), CAVâs Monteria 28 (85 %), Barranquillaâs Zoo 14 (87 %), Caliâs Zoo 21 (84 %) and from the CAV Victoria del Oriente Caldense 19 (79 %) sera were seropositive. Regarding seroprevalence in humans, 30 of the 39 (78 %) were seropositive, regional seroprevalence was as follow: Montería 9 (100 %) workers, Barranquillaâs Zoo 9 (90 %), CAV Caldas Tower four 4 (80 %), Caliâs Zoo 5 (45 %) and CAV Caldense Victoria del oriente 3 (75 %) were seropositive. Conclusions The high seroprevalence of Chlamydophila psittaci in birds (86,4 %) and humans (78 %) showed the first evidence of circulation of this microorganism in Colombia; the circulation of the etiological agent of psittacosis may represent a public health risk.
