Results are presented of serological examinations of 194 pheasants (Phasianus colchicus) and 114 pigeons (Columba livia f.domestica) for the presence of antibodies to Chlamydia psittaci. Seropositivity was detected in 40.7 % of pheasants (28.5-45.9 % in dependence on sampling date) by a micro-method of complement fixation reaction when a genus specific antigen Ch. psittaci) was used. The unapparent form of chlamydiosis was demonstrated by the antibody levels (1:128). 64.0 % of pigeons showed seropositivity while differences in the number of positive birds and antibody levels were large in relation to sampling dates. 35.7 % of birds showed seropositivity with maximum antibody titer 1:128 in a group of 42 pigeons entrapped in January 1999 while a group of 72 pigeons entrapped in April 1999 comprised 80.5 % of birds with seropositivity and antibody titer 1:1024. These results document an acute form of chlamydiosis and suggest that pigeons are a very important source of chlamydiosis for the human and animal populations.
