Prevalence and associated risk factors of gastrointestinal helminths and coccidian infections in domestic goats, Capra hircus, in Minya, Egypt

Abstract

Abstract Background Helminth and coccidian infections are among potential parasitic infections in the livestock production. The present study aimed to determine the prevalence and intensity of gastrointestinal helminths as well as Eimeia species in domestic goats. Results The overall prevalence of parasitic infections was 50.24% (206/410). Twenty two species of helminth eggs/Eimeria spp. oocysts were revealed. The prevalence of helminths was 21.95% (90/410) and that of Eimeria spp. was 39.27% (161/410). Mixed infection was reported in 10.98% (45/410). The highest prevalence was found in young animals (75.0%; 60/80) followed by yearlings (58.46%; 76/130) and the lowest one was in adults (35.0%; 70/200). The infection rate was higher in females (59.02%; 180/305) than males (24.76%; 26/105). The prevalence was mostly highest in summer (63.85%; 83/130) followed by winter (57.78%; 52/90), autumn (40.0%; 28/70) and the lowest one was in spring (35.83%; 43/120). Age, sex and seasonal variations revealed significant (P ≤ 0.05) differences among examined goats. The infection with both nematodes and Eimeria spp. were detected in 7.32% (30/410). The co-infection with Eimeria spp. and tapeworms were found in 2.93% (12/410). Both trematodes and Eimeria spp. were seen in 0.73% (3/410) of examined specimens. Nine Eimeria species were recorded; Eimeria ninakohlyakim-ovae, E. hirci, E. caprinova, E. caprina, E. christenseni, E. jolchijevi, E. arloingi, E. apsheronica and E. alijevi. The most predominant Eimeria species was E. arloingi (23.17%; 95/410) and the least abundant one was E. apsheronica (0.73%; 3/410). The revealed trematodes were Fasciola spp. (0.49%) and Paramphistomum spp. (0.24%). Among cestodes, tapeworms belonged to Anoplocephalids included Moniezia spp. (7.31%) and Avitellina sp. (0.49%) were detected. Meanwhile, coproculture revealed that the prevalence of nematodes infection was 13.41% (55/410) including nine species; Chabertia ovina, Ostertagia ostertagi, Haemonchus contortus, Trichostrongylus axei, T. colubriformis, Bunostomum sp., Cooperia oncophora, Cooperia curticei and Strongyloides spp. Conclusion In the present study, the prevalence of helminths was 21.95% and that of Eimeria spp. was 39.27%, which is considered a high infection rate. Accordingly Strict hygienic measures as well as regular deworming are highly recommended to avoid wide spread of both helminth and coccidial infections.
