“…The prevalence values of the gastrointestinal parasites recorded in the present study are, on the whole, in line with most of the studies conducted in Ethiopia [3,5,[10][11][12][13]15,[32][33][34][35][36][37][38][39][40]. In some studies, gastrointestinal nematodes (GIN) were considered all together, including GIS, Strongyloides spp., ascarids and trichurids, and the overall prevalence was, therefore, exceeding the prevalence of GIS alone [5,13,36,39].…”

Parasitic diseases are a major impediment to livestock production worldwide. However, knowledge about the epidemiology of gastrointestinal parasites in many low-income countries is still limited. An epidemiological survey on these parasites in traditionally reared cattle was performed in central Ethiopia (West Shewa Zone), from September 2019 to November 2021. Overall, 691 samples were analyzed qualitatively (flotation technique) and quantitatively (McMaster technique) to detect helminth eggs and Eimeria oocysts. Furthermore, coprocultures were conducted on pooled samples to identify the genera of gastrointestinal strongyles (GIS). The difference in prevalence according to agroecology, season, age, sex and body condition score (BCS) was investigated using univariable tests and through a multivariable logistic regression analysis, whereas abundance values were interpreted using a descriptive approach. The highest prevalence values were observed for GIS (50.2%) and Eimeria spp. (36.0%), whereas Moniezia spp. (16.3%), Strongyloides spp. (5.1%) and Schistosoma spp. (4.2%) showed lower values. Trichuris spp. and Toxocara vitulorum were sporadically found. A coproculture revealed that Haemonchus spp. (34.6%), Trichostrongylus spp. (25.9%) and Bunostomum spp. (19.1%) were the most frequent genera of GIS. A poor BCS was strongly associated with the occurrence of GIS, while seasonal variations were detected for Eimeria spp., GIS, Moniezia spp. and Schistosoma spp., with a higher prevalence and burden during the rainy season, and agroecology also strongly influenced different parasitic taxa. This present study increases the knowledge about the epidemiological features of gastrointestinal parasites in the context of a low-income country, suggesting a more tailored approach for their control. The use of a BCS as an indicator for the selective treatment of highly infested animals is supported by our findings, introducing a possible way to prevent anthelmintic resistance in areas where basic diagnostic services are rarely used by farmers.

“…Schistosomiasis treatment aids in the reversal of acute or early chronic disease, as well as the prevention of problems associated with chronic infection. The most efficient strategy to control cattle schistosomiasis in endemic areas is to avoid contact between the animals and the parasite [ 9 , 10 ]. With the presence of large permanent water bodies and marshy grazing areas in the Tis Abay district, bovine schistosomiasis might be present in the area.…”

Background. Schistosomiasis is a parasitic disease of cattle that is caused by trematode worms and results in morbidity, mortality, reduced fertility, and productivity. Methods. A cross-sectional study was conducted to determine the prevalence and associated risk factors for bovine schistosomiasis in Tis Abay district, Amhara, Ethiopia. Fecal samples were collected from 384 randomly selected cattle and examined using the sedimentation technique. Results. Of the total examined fecal samples, 13.02% (50/384) of the samples were positive for Schistosoma bovis eggs. The prevalence of schistosomiasis was highly reported in Dasra (22.4%), which was statistically significant ( p ≤ 0.001 ). The prevalence of bovine schistosomiasis was higher in females (16.9%), crossbred cattle (17.1%), poorly conditioned cattle (37.1%), extensively managed cattle (17.9%), and cattle greater than 5 years old (23.1%). The multivariate analysis of factors revealed that study area, age, breed, body condition, and management system have a significant role ( p < 0.05 ) in the prevalence of bovine schistosomiasis. Conclusion. Schistosoma infection is a problem for cattle in the study region. Therefore, farmers should be aware of the transmission of the disease, prevention, and control of snails.

“…The prevalence rates reported by 16,[30][31][32][33][34][35][36] are in line with the prevalence observed in our study. The coprological investigation yielded better outcomes than prior discoveries by 11, with a predominance of 5.7% in and around Nekemte, 10 with a pervasiveness of 13.02% in Tis Abay District, 15 with a predominance of 16.7% in chosen areas of the South Wollo and Oromia Zones of the Amhara Region, and 13 with a predominance of 16.28% in FogeraWoreda. These findings are lower than those of past reports 37 in and around Gozamen District, 38 in the Bahir Dar region, 39 in chosen locations of Bahir Dar, and 40 and associates, who generally reported a predominance of 26.3%, 29%, 37.3%, and 27.13%, respectively.…”

“…A confirmatory diagnosis of ongoing schistosomiasis in cattle can only be achieved through the detection of parasite eggs in fecal samples or biopsy specimens from the affected animal. 15 The treatment of schistosomiasis not only facilitates the reversal of acute or early chronic disease but also serves to prevent complications associated with chronic infection and the development of neuro schistosomiasis. 16 The most effective approach to controlling schistosomiasis in prevalent regions involves the implementation of measures such as the construction of barriers around perilous bodies of water and the provision of uncontaminated water sources to prevent contact between the parasite and the animals.…”

Schistosomiasis is caused by the Schistosoma genus and is transmitted through intermediate hosts, such as snails. Methods: A cross-sectional investigation was conducted within and surrounding Haramaya town between December 2022 and May 2023 to estimate the prevalence of schistosomiasis in cattle and associated risk factors. The degree of prevalence was estimated using surveys carried out in slaughterhouses and coprological laboratories. For statistical estimation, chi-square tests and logistic regression were utilized. A total of 390 samples were obtained through simple random sampling. In the survey that was undertaken on abattoirs, a total of 384 samples were chosen through the utilization of a systematic random sampling approach. The recovery of Schistosoma eggs from fecal specimens was achieved by sedimentation. Results:The overall rates of schistosomiasis in cattle were estimated to be 21.28% and 18.23% through coprological and postmortem examinations, respectively. The analysis conducted through multivariable logistic regression indicated that management system, body condition, and age were significant risk factors. Cattle under extensive management (OR = 5.9, 95% CI = 2-17) and those in the young age category (OR = 2.7, 95% CI = 1.0-7.00) were more susceptible to acquiring schistosomiasis than cattle under intensive management and those in the adult age category, respectively. According to the odds ratio, there was a positive association between the incidence rate of schistosomiasis in cattle and poor body condition (OR: 3.048, 95% CI = 1.07-8.68; P = 0.00). Schistosomiasis infection was 3.048 times more likely to manifest in animals in poor physical condition. This affliction has had a profound impact on the livestock industry, as substantiated by the elevated prevalence of schistosomiasis in cattle within the studied region. Conclusion:Consequently, an integrated approach to prevention and control that targets the parasite is needed.
