Table 1 Herd-level seroprevalence of bovine brucellosis based on RBPT and c-ELISA, adjusted for sampling weights, and presence of hygroma, orchitis or epididymitis in three states of northern Nigeria

From: A large seroprevalence survey of brucellosis in cattle herds under diverse production systems in northern Nigeria

State n RBPT pos. (%) c-ELISA pos. (%) 95% CI Hygroma (%#) Orchitis/ Epididymitis (%#)
Adamawa 100 89 (88.0) 84 (82.3) 66.8 - 91.5 54 (64.3) 12 (14.3)
Kaduna 105 78 (74.8) 75 (72.0) 58.6 - 82.4 2 (2.7) 12 (16.0)
Kano 66 58 (89.6) 51 (78.5) 61.2 - 89.4 7 (13.7) 7 (13.7)
Overall 271 225 (84.9) 210 (77.5) 68.6 - 84.5 63 (30.0) 31 (14.8)
  1. Key:
  2. n: Sample size.
  3. c-ELISA: Competitive enzyme-linked immunosorbent assay.
  4. RBPT: Rose-Bengal plate-agglutination test.
  5. CI: Confidence Interval.
  6. # Percentage of c-ELISA-positive herds showing hygroma, orchitis or epididymitis.
