Concurrence of Eimeria and helminth parasitic infections in West African Dwarf kids in Ghana

The sequence of appearance of Eimeria and helminths, in 20West African Dwarf kids from birth and the pattern of oocyst and strongyle worm egg output for 1.5 years are described. Eimeria oocysts appeared early about 20 days after birth and oocyst output in some kids reached 2.7 million oocysts per gram (opg) of faeces about 39 days after birth and showed a group mean oocyst output of 443,540 opg in the second month but this declined further to 23,840 opg after 5.5 months. Eimeria arloingi (20.50%), Eimeria ninakohlyakimovae (17.02%), Eimeria alijevi (15.07%), Eimeria caprina (12.65%), Eimeria jolchijevi (11.42%), Eimeria apsheronica (8.70%), Eimeria pallida (5.31%), Eimeria caprovina (3.29%), Eimeria hirci (3.20%) and Eimeria christenseni (2.84%) were seen in a descending order of prevalence. Strongyle worm ova were seen 53 days after birth and peaked soon after the fall in Eimeria oocyst output but thereafter fluctuated. The eggs of cestode, Moniezia spp. appeared later but was transient. Both oocyst and worm egg output declined and were almost absent when the kids were about 1 year old. Faecal larval cultures were made and the L3s identified with the dominant ones being Haemonchus spp. and Trichostrongylus spp. Sixty percent of the kids in this study died when they were 7 months old and a total of 70% of the kids had died before they were 1 year old. © 2003 Elsevier B.V.
