    Ceylonocotyle, Bothriophoron, and Calicophoron species Parasitic in some Nigerian Cattle
    (Society of Education, 2013-06) Dube, S.; Onyedineke, N.E.; Aisien, M.S.O.
    The following genera Ceylonocotyle, Bothriophoron and Calicophoron were recovered from the inner walls of stomachs of cattle slaughtered in abattoirs in the North and South of Nigeria. Some parasites were flattened and diagnostic features taken while some were sectioned in the median saggital plane from where the histology and morphology of the pharynx, genital atrium, acetabulum and testis were analysed for identification. Ceylonocotyle dicranocoelium. Bothriophoron bothriophoron, Calicophoron calicophorum, and Calicophoron microbothrioides were identified. Photomicrographs of the features used in identifications were made and are here presented. Damage to host tissues of the reticulum and rumen was in the majority of cases severe when Ceylonocotyle dicranocoelium was present but the other species did less damage to rumens and reticulum. Parasite loads ranged between 20 and 200 parasites in the infected animals and frequencies of occurrence in cattle were 10% for Ceylonocotyle dicranocoelium, 2 % for B. bothriophoron, 15% for C. calicophorum, and 5 % for C. microbothrides. All the described parasites are being reported in Nigeria for the first time.

    Descriptive studies on Paramphistomes of small domestic ruminants in Southern Nigeria
    (ZJST, 2010) Dube, S.; Aisien, M.S.O.
    Goats and sheep slaughtered in Southern Nigeria had their rumens and reticulums examined for the frequency and intensity of infections with paramphistomes. The overall frequency of infected goats and sheep was 30% and 80% respectively. The range of intensity of parasite in goats and sheep was, 2 to 500 and 2 to 700 respectively. From the morphological and histological studies of diagnostic features, which included the acetabulum, genetilium and pharynx, carried out on flattened whole mounts and median sagittal sections the following parasites were identified, Cotylophoron cotylophorum infecting 8% of the goats,Cotylophoron fuelleborni infecting 20% of the goats, Carmyerius synethes infecting 4% of the goats and 70% sheep, and Calicophoron microbothrium infecting 20% of the goats and 33%,sheep. Goats were infected with all the four species while sheep infected with only the last two species. The degree of tissue damage on both hosts was mild.
