The prevalence of chlamydial infection in dairy goats in
Shaanxi province, Northwestern China was determined by
indirect hemagglutination antibody (IHA) on serum samples
from 729 dairy goats (263 Saanen dairy goats and 466
Guanzhong dairy goats). Antibodies to Chlamydophila
sp. were detected in 21 (2.88%) serum samples, with antibody
titers ranging from 1:16 to 1:64. Seropositive goats were
found only in three (Zhuangli town, Wangliao town and
Yangling district) of the nine locations/herds examined in
six counties. The prevalence of chlamydial infection was
significantly related with locations/herds (χ2 = 54.36, P
= 0.00) and breeds (χ2 = 56.50, P = 0.00). Both
Saanen and Guanzhong dairy goats were positive for
chlamydial infection, with higher seroprevalence in
Saanen dairy goats (5.70%, 15/263) than that in Guanzhong
dairy goat (1.29%, 6/466). The results of the present study
indicate that more integrated strategies should be carried
out to prevent and control chlamydiosis in goats in Shaanxi
