“…The seeming high prevalence of haemoparasites in females than in the males could be related to the proportion of the populations sampled. This corroborates the findings of Samdi et al [13]. Most households keep females than males especially for breeding purposes.…”

“…This could be attributed to the dry weather conditions allowing free roaming and spread of diseases in animals. However, this was in contrast with the findings of Samdi et al [13], who observed high prevalence of haemoparasites during rainy season. The relativesly low prevalence of haemoparasites in the months of June, July and August could be attributed to the rainy weather conditions apparently not suitable for spread of vector transmitted disease.…”

Out of 503 dogs samples analyzed 104 were males and 303 females and out of these 359 (71.4%) were positive for haemoparasites. Babesia spps (94.4%) had the highest prevalence compared to Trypanosomes 5.0% and Anaplasma spps 45.0%. Most of the dogs had mixed infections of Babesia and Anaplasma spps. The prevalence was higher in females 76.3% compared to males 54.0%. Out of the areas sampled, MOUAU community had 20.0%, Oboro 91.4%, Oloko 8.0%, Ibere 18.0%, Ariam 59.0% and Usaka 58.3%. The highest prevalence was recorded in December (90.0%), March (83.3%) and November (83.3%) whilst the remainder of the months had April (77.1%); May (70.0%); June (68.0%); July (63.3%) and August (53.1%). There were significant decreases in the PCV and Hb of the infected groups.

“…Ces résultats ne corroborent pas ceux obtenus par Farougou et al (2007). Par contre, ils sont en accord avec ceux obtenus par Samdi et al (2008) à Kaduna au Nigéria. En effet, l'intensité de l'infestation par les hémoparasites à tiques est généralement basse en saison sèche et élevée en saison de pluie (Jongejan, 1994).…”

Les hémoparasitoses constituent des contraintes pathologiques graves qui entravent le développement de l'élevage des ruminants en général, et celui des petits ruminants en particulier en Afrique tropicale. En vue de déterminer la prévalence des principales hémoparasitoses transmises par les tiques, aussi par les mouches piqueuses hématophages ou même des instruments souillés de sang, et les facteurs de risque de ces infections, une étude a été réalisée chez les petits ruminants abattus dans la ville de Ngaoundéré. Un total de 678 échantillons de sang a été prélevé sur des petits ruminants de différents sexes, races et groupes d'âge. Les prévalences des hémoparasites ont été déterminées à l'examen de frottis colorés au Giemsa et à la technique de centrifugation à hématocrite. La prévalence globale déterminée à partir des 678 animaux prélevés était de 28,9%. Sur les 678 sérums analysés, 117 (17,3%) ont été séropositifs et six espèces d'hémoparasites ont été observées avec une séroprévalence qui a varié selon le parasite considéré : Anaplasma spp (9,1%), Babesia spp (2,9%), Theileria spp (3,8%), Trypanosoma congolense (0,7%), Trypanosoma brucei (0,4%) et Trypanosoma vivax (0,1%). Les animaux jeunes avaient une prévalence moins élevée que les animaux adultes. Les femelles avaient également une prévalence plus élevée que les mâles. La prévalence obtenue en saison de pluie était plus élevée que celle de la saison sèche. L'analyse statistique a montré que l'âge, le sexe et la saison étaient les facteurs de risque pour les hémoparasites, tandis que la race a eu une influence moindre. Les résultats de cette étude confirment l'endémicité des hémoparasitoses chez les petits ruminants à Ngaoundéré quel que soit le groupe d'âge. Il importe donc de prendre des dispositions pour lutter contre ces hémoparasitoses afin d'éviter une instabilité enzootique.

“…Both Trypanosoma congolense and Trypanosoma vivax are pathogenic to the local cattle with variable clinical manifestations, depending on the nutritional status of the affected animal (7,8). Previous reports in Nigeria showed that infections in small ruminants with these parasites are higher during the rainy season than the dry season (9). They are transmitted cyclically by tsetse fly (Glossina species).…”

A study was conducted to compare the clinical presentation and pathology of some organs associated with experimental infection of Nigeria field isolates of Trypanosoma vivax and Trypanosoma congolense in the Yankasa breed of sheep. Thirty adult Yankasa sheep of both sexes were used. They were screened for hemo-, endo-, and ectoparasites and treated and conditioned for 2 weeks. They were divided into 5 groups (A, B, C, E, and F) of 6 animals each. Two groups each (A, B and E, F) were infected with 2 mL of infected blood containing approximately 2.0 × 10 6 of T. vivax and T. congolense, respectively. Groups B and F were left untreated and monitored for 7 weeks while groups A and E were treated at the peak of parasitemia with a trypanocide. Group C served as an uninfected control. Clinical signs observed in both groups were anorexia, rough hair coat, ocular discharge, pale mucous membrane, diarrhea, severe weakness, depression, edema of the eye lids in some animals, and emaciation. In addition, teeth grinding and torticollis-like central nervous system disorders were also observed in some animals in group B. Some gross and histopathological lesions were seen in both groups in the lungs, liver, spleen, kidneys, brain, skeletal muscles, and hydropericardium.
