True seroprevalence of chlamydiae at animal and herd level in cattle herds in the voivodeships of Poland based on serum analyses by complement fixation test. TPH – true-positive herds; TPA – true-positive animals; Voivodeships: GP – Greater Poland; PDL – Podlaskie; SW – Świętokrzyskie, LDZ – Łódź; KP – Kuyavia-Pomerania; MAS – Masovia; OPO – Opole; LP – Lesser Poland; SUB – Subcarpathia; WP – West Pomerania; LB – Lublin; SL – Silesia; POM – Pomerania; LS – Lower Silesia; LU – Lubusz; WM – Warmia-Masuria – the size of the symbol corresponds to the number of cows in the voivodeship

Multivariate analysis of the presence of antibodies against chlamydiae in sera at herd and animal level, the geographical location of the farms and the dairy cow stock in the voivodeship and the positive and negative conformity rates between the results of serological screening for chlamydiae and Coxiella burnetii in the same sera samples. Blue points represent each category of analysed variables. Blue points with similar profiles (low value of distances indicating a strong association between variables) are marked by the red rectangles. Blue points located in the green rectangle in the graph’s centre show the points with similar profiles but representing eigenvalues indicating the lack of any association. Blue points located in the dashed rectangle shows the points with similar profiles but representing eigenvalues indicating the association with more than one groups ACh+ – seroprevalence of chlamydiae at animal level; HCh+ – seroprevalence of chlamydiae at herd level; CP – dairy cattle population; Con Pos Q/Ch – conformity between positive results of presence of Chlamydia spp. and Coxiella burnetii antibodies in the same sera samples; Con Neg Q/Ch – conformity between negative results of presence of Chlamydia spp. and Coxiella burnetii antibodies in the same sera samples. Voivodeships: GP – Greater Poland; PDL – Podlaskie; SW – Świętokrzyskie, LDZ – Łódź; KP – Kuyavia-Pomerania; MAS – Masovia; OPO – Opole; LP – Lesser Poland; SUB – Subcarpathia; WP – West Pomerania; LB – Lublin; SL – Silesia; POM – Pomerania; LS – Lower Silesia; LU – Lubusz; WM – Warmia-Masuria
