Abstract

A cross-sectional study was conducted to determine the prevalence and economic significance of Fasciolosis, and the morphometry of Fasciola species in slaughterhouse ruminants. A total of 345 cattle, 370 sheep, and 370 goats were examined using systematic sampling technique at meat inspection.  The monetary loss due to liver condemnation was estimated and morphometry of Fasciola spp. was measured. SPSS version 21 was used for statistical analysis. A prevalence rate of 32, 9, and 6% was recorded in cattle, sheep and goats, respectively. The overall monetary loss due to liver condemnation was approximated at $2,994. Significant differences (P < 0.05) in body length, body width, and cone length and width showed Fasciola hepatica shorter in length (29.6 ± 4.74 mm) compared to Fasciola gigantica (53 ± 5.89 mm). The F. hepatica was characterized by broader shoulders (9.10 ± 1.30 mm) compared to F. gigantica (6.38 ± 1.40 mm). The cone length of F. gigantica species was longer (3.65 ± 0.40 mm) than F. hepatica species (3.13 ± 0.36 mm). The cone width of F. gigantica species (4.40 ± 0.60 mm) was wider than that of F. hepatica (3.73 ± 0.64 mm). The results of this study showed a significant prevalence of Fasciolosis in Juba County causing significant monetary loss to livestock traders due to liver condemnation at meat inspection. Consistent overlapping values of maximum and minimum cone length and width for distinguishing Fasciola species proved by morphometric technique was less sensitive. Strategic preventive and control measures against the parasite and vector snails are recommended. Further studies are needed on molecular epidemiology and characterization of Fasciola spp. among ruminants in Juba County, South Sudan.
