Figure 1. Development of calves and chlamydial infection.

Figure 1

The progression over the sampling period is shown (n = 51). (A) Body weight gain over successive 2-week periods and absolute body weight. (B) Conjunctival inflammation as expressed by an arbitrary score from 1–4 for redness, with 2 for normal pink coloration of the conjunctiva. (C) Average C. pecorum genomes per cytobrush swab detected by Chlamydia spp. 23S rRNA gene real-time FRET PCR. Early, midpoint, or late indicates peak C. pecorum infection before week 9, in week 9 or 11, or in week 13 or 15. For clarity, only the mean of all calves is shown with error bars. (D) Anti-C. pecorum IgM antibodies as determined by chemiluminescent ELISA using a lysate antigen of C. pecorum elementary bodies. Data are shown as means ± SEM.
