“…(p>0.05). The finding of higher prevalence of infection in the poor body condition animals (7.3%) than the good body condition ones (3.8%) corroborates the reports of Tafese et al (2012) that good body conditioned animals had less infection with trypanosome when compared with the poor conditioned ones. There was no significant difference (p>0.05) between the prevalence of infection in good and poor body conditioned animals.…”

A cross-sectional study to determine the prevalence of trypanosomosis in Bassa Local Government Area of Plateau State was carried out on 462 animals (361 cattle and 101 sheep) purposively selected. Blood samples were examined for trypanosomes and the packed cell volume was determined. Biconical traps were set to catch biting flies which were later dissected. The body condition scores of the selected animals were also noted. Out of the 462 blood samples examined, 22 (4.8%) tested positive for trypanosomes. Sheep had higher trypanosome prevalence of 6.9% than cattle 4.2%. The most prevalent species encountered was Trypanosoma vivax (86.4%) followed by T. brucei (13.6%). Trypanosoma vivax was also more predominant in cattle 13 (86.7%) than sheep 6 (85.7%). White Fulani and Red Bororo cattle had 4.2% and 0.0% prevalence, respectively while Yankasa sheep, the only sheep breed sampled, had 6.9%. Male cattle and sheep were more infected with the prevalence rates of 5.0% and 7.4%, respectively than their female counterpart (3.6% for cattle and 6.8% for Sheep). Young cattle (< 3yrs) and sheep (≤ 2yrs) had higher trypanosome infection rates of 5.4% and 9.4% than the adult cattle (≥ 3yrs) and sheep (>2yrs) having the prevalence rates of 3.1% and 4.2% respectively. Poor body conditioned animals had higher trypanosome prevalence (7.3%) than the good body conditioned ones (3.8%). Age, sex, breed and body condition score of animals examined did not influence the infection rate of trypanosome species (p>0.05). The mean PCV ± standard deviation of infected animals (21.73 ± 4.81) was significantly lower than non-infected animals (26.89 ± 4.37) p < 0.05.The study revealed an overall relative low fly density of 0.39 flies/trap/day and flies dissected were negative for trypanosome infection. This present study revealed trypanosome and their vectors are present in the study area. Therefore, improved Veterinary extension services and education should be implemented.

“…The apparent densities of Glossina species was 0.24 and 1.09 fly/trap/day in Gambela and Abobo districts respectively. This result is in agreement with different reports in western, south, south western and north western part of the country: 1.45 and 0.58 fly/trap/day in two districts of East Wollega zone, western Ethiopia [31], and 1.14 fly/trap/day in Southern Rift Valley of Ethiopia [32]. The sex category indicated male and female tsetse fly account for 36.70% and 63.30% of total caught Glossina species, respectively.…”

The study was conducted from October 2015 to November 2015 in Gambela and Abobo districts of Gambela Peoples Regional State, southwestern Ethiopia. It was designed to avail information on prevalence of bovine trypanosomosis and apparent densities of vectors of the trypanosomosis. A parasitological study using buffy coat technique was employed for the determination of prevalence of trypanosomosis while baited mono pyramidal traps were used for the vector survey. A total of 862 cattle randomly selected from the study population were examined for the parasitological study. The result of parasitological study revealed that the overall prevalence of trypanosomosis was found to be 16.59%, 95% CI=14.10-19.08 indicating trypanosomosis is a serious problem in the area. Three Trypanosoma species were identified during the study period: Trypanosoma brucei, T. vivax and T. congolense. Highest trypanosome prevalence (18.67%) was seen in animals with poor condition than that of those with medium (16.76%) and good (14.20%) body condition for the concerned blood parasite but no significant difference was observed (P>0.05). Higher infection rate was occurred in male (18.35%) than female (14.79%) cattle without significant difference (P>0.05). Prevalence was significantly higher in adult animals (17.95%) than younger ones (7.27%) (P>0.05). The study suggested that mean PCV values of parasitaemic (21.13%) cattle was significantly lower than aparasitaemic (22.26%) animals (P<0.05). During entomological survey, four species of tsetse fly: G. tachnoides, G. morsitsns submorsitans, G. pallidipes and G. fuscipes fuscipes and three genera of other biting flies: Tabanus, Haematopota and Stomoxys spp. were caught. The overall apparent density of tsetse flies was 0.75 fly/trap/day. Trypanosomosis and tsetse fly pose great threat to cattle residing in study areas. Thus, appropriate intervention measures need to be taken.

“…This study finding is also in line with that of Bitew et al (2011), Teka et al (2012) and Fayisa et al (2015), who reported that statistically significant association between prevalence of trypanosomosis and body condition in cattle. However, in contrary to this Abebayehu et al (2011), Bekele and Nasir (2011), Tafese et al (2012), Dawit et al (2015) and Kitila et al (2017) reported that body condition of cattle was not significantly associated with the prevalence of trypanosomosis in cattle.…”

Trypanosomosis is a serious disease that causes a significant production loss in cattle. A cross sectional study was conducted in Jimma Horro District of Kellem Wollega Zone, Western Ethiopia to determine prevalence and associated risk factors of bovine trypanosomosis from October 2016 to October 2017. Blood samples from randomly selected 384 cattle of both sex and different age group were collected and examined with parasitological techniques. The overall prevalence of bovine trypanosomosis was 3.7% (14/384) in the study areas. The infection was highest due to Trypanosome congolense (50%) followed by Trypanosome vivax (28.6%) and Trypanosoma brucei (21.4%). Multivariable logistic regression analysis identified body condition as risk factors (P<0.05) for trypanosomosis in the district. However, there were no statistically significant difference observed among age groups, sex, skin color and different peasant associations (P> 0.05). The overall mean Packed Cell Volume (PCV) value was statistically significant difference between aparasitaemic and parasitaemic cattle (P< 0.05).The study showed that bovine trypanosomosis is one of the constraints to cattle production in Jimma Horro District. Hence, there is a need to create awareness about impact of disease on cattle production and appropriate control methods of trypanosomosis should be designed and implemented.
