“…Similar findings were also reported by Alula et al (2013) and Abebe et al (2008). Higher infection rate was observed in calf ≥ 6 to 12 months of age than calves of <6 months of age which is similar to the study of Das et al (2015) and Gezaleign (2011). This is due to the fact that there was good nursing and feeding colostrum for younger calves.…”

“…The overall Eimeria intensity based on oocyst per gram of feces (OPG) ranged from 50 to 32,000. This is higher than 50-1500 OPG in study conducted in India (Das et al, 2015). This could be due to susceptibility differences, geoecological and seasonal variations (Radostits et al, 2006).…”

“…The present study showed prevalence of E. bovis (26.6 %) and E. zuernii (11.2%) which is lower than the report of E. bovis (42.3%) and E. zuernii (28.3%), in previous study in Ethiopia (Alula et al, 2013). Das et al (2015) reported lower prevalence of E. bovis (6.8%) and E. zuernii (2.35%).…”

A cross-sectional study was conducted from November 2015 to March 2016 with the objectives of estimating the prevalence of coccidiosis, identifying the most known pathogenic coccidia species involved, and assessing the overall knowledge of dairy farm owners and workers on calve coccidiosis and adapted control methods in randomly selected 7 kebeles of Mekelle dairy farms. Two hundred thirty two fecal samples were randomly collected from calves belonging to seventy dairy farms and examined for the presence of oocysts of Eimeria by floatation technique using saturated salt solution. For positive samples, solution of 2.5% potassium dichromate was added to the feces containing the oocyst for sporulation and identification of the Eimeria species. The risk factors and the overall knowledge on calf coccidiosis and adapted control methods were assessed by two types of questionnaires and a prepared observational format. The overall prevalence of coccidiosis was 72.7% (169/232) and the identified Eimeria species were E. bovis and E. zuernii with the prevalence of 26.6% (45) and 11.2% (19); respectively. There was statistically significant difference (p< 0.05) among various age categories with the infection of Eimeria species. However, sex and body condition of animals were not significantly associated (p > 0.05) with Eimeria infection. Questioner survey result of animal health experts and owners showed 33 calves were suspected to be infected with pathogenic Eimeria spp. In conclusion, the study revealed that calf coccidiosis is prevalent in dairy farms of Mekelle. Hence, appropriate disease prevention and control program need to be undertaken to reduce its impact.

“…The highest contributions for Eimeria distribution arise for the warm-climate adapted species, suggesting the large influence of temperature on the colonization and survival of this parasite. These findings are not in conformity with other studies that conclude that rainfall and soil moisture is the most relevant factor that contributes to the prevalence of Eimeria [32] [33]. Similarly, authors have estimated 62% of positive calves in a dry region of Mexico [34], hence supporting the importance of precipitation as a pertinent factor driving the distribution of this parasite in Mexico.…”

Coccidiosis is a gastrointestinal disease caused by parasites of the genus Eimeria. To produce the ecological niche model for the geographic distribution of Eimeria species, the maximum entropy algorithm (MaxEnt) was used and 19 bioclimatic variables with a spatial resolution of 30 arc-seconds (approximately 1 km 2) were downloaded from the World Climate Database. These were reduced to BIO2, BIO3, BIO4, BIO7 and BIO15 for each species after examining cross-correlations among them to account multicollinearity. A jackknife analysis was included to assess the contribution of five bioclimatic variables and the fit of the model was evaluated with the area under receiver operating characteristic curve (AUC). Under a current climate scenario, the jackknife evaluation of the MaxEnt model showed that BIO4 (temperature seasonality) made the greatest contribution to the distribution model for 22 Eimeria species; whereas BIO7 (temperature annual range) was the most important factor that contributes to the distribution model of 10 species. The habitat suitability model based on the maximum entropy theory was supported by AUC values higher than 0.9 and predicted that the suitable habitats for different species of Eimeria are present in southern, eastern and western areas of Mexico. Our study may support future studies exploring factors that constrain the distribution of Eimeria as well as strategies aimed at reducing the disease prevalence.

“…(13.3%) in Southern Germany, Hussin (2016) (9.5%) in Iraq andDas et al (2015) (11.9%) in India. Such inconsistency in the prevalence rate of coccidiosis may be due to the variation in diagnostic tests, age of the animals, susceptibility of different breeds to the disease, stress level, handling, climatic and other factors of agro-ecology, variation in the study season, number and target group of the study animals and husbandry practices(Radostitis et al, 2007a;Abebe et al, 2008;.…”

Bovine coccidiosis is a protozoan infection caused by different species of Eimeria which has a worldwide distribution. The disease which mainly affects calves belongs to large herd size where hygiene is not well managed and is associated with poor body condition. A cross-sectional study was conducted from November 2016 to April 2017 to determine the prevalence of bovine coccidiosis and identify the associated risk factors in semi intensive and extensive dairy farms in and around Holeta town, Finfine Zuria Liyu Zone, Oromia Regional State, Ethiopia. Fecal samples were randomly collected from three hundred and eighty four calves belonging to dairy farms and examined for the presence of the oocyts of Eimeria by floatation technique using saline solution. The study revealed that the overall prevalence of coccidiosis was 26.04%. The risk factors considered were age, sex, breed, production system, herd size, fecal consistency, body condition and hygienic status of the house. The prevalence of coccidiosis was higher within calves in poor hygienic (58.6%) dairy farms than calves from better hygienic farms (14.6%). There was also significant difference (P<0.05) in the prevalence of coccidiosis between different herd sizes with higher prevalence in herd size >10 animals (39.3%). The highest prevalence of coccidiosis was recorded in calves with diarrheic faeces (91.7%) than calves with soft, constipated and normal fecal consistency (P<0.05). Appropriate monitoring and control of the disease is advisable in the study farms.
