Table 2 Comparison of indices of cattle antibody reactivities with female or male excretory/secretory (ES) products after 4 or 36 months of exposure

From: Onchocerca - infected cattle produce strong antibody responses to excretory-secretory proteins released from adult male Onchocerca ochengi worms

Worm sex, Exposure time (number of worms) Indices of IgG reactivity for ES proteins (if > 0)
Median (IQR)
female, months 4 (6) 305 (280–488)
female, months 36 (9) 924 (355–1019)
male, months 4 (12) 504 (188–863)
male, months 36 (15) 958 (664–1160)
  Indices for ES proteins = 0 vs. ES proteins > 0
Chi square test
female 4 vs. female 36: 6/25 (24%) vs. 9/27 (33%); p = 0.46
male 4 vs. male 36: 12/25 (48%) vs. 15/27 (56%); p = 0.59
female 4 vs. male 4: 6/25 (24%) vs. 12/25 (48%); p = 0.08
female 36 vs. male 36: 9/27 (33%) vs. 15/27 (56%); p = 0.10
