“…During the present study highest overall prevalence of infection was recorded with nematode parasites followed by trematodes, whereas cestodes were found to be the least represented group. A similar observation was made by Almalaik et al, (2008) and Besier et al, (2016) where they noted high prevalence with the nematode parasite Haemonchus (Strongyle) in all domestic ruminants. In accordance with the present observations, previous studies have also recorded greater prevalence of infection in buffaloes and sheep when compared to cattle and goat (Mamun et.al., 2011;Gupta & Singla 2012;Singh et al, 2013;Patel et al, 2015;Varadharajan & Vijayalakshmi 2015;Singh, et.al., 2015).…”

Coprological studies on the prevalence of gastrointestinal helminth (GI) parasites in domestic ruminants from Srikakulam district of Andhra Pradesh, India, were carried out for a period of one year from January 2019 to December 2019. Fecal examination was done using direct smear, sedimentation and oatation methods. Altogether 3,527 fecal samples were examined including 595 from cows, 485 from buffaloes, 1342 from sheep and 1105 from goat. Out of 3,527 fecal samples examined, 1084 were found to be positive with three groups of gastrointestinal parasites (GI) showing an overall prevalence of 30.7%.Maximum infection was noted with nematodes (39.1%) and trematodes (37.3%), least infection was noted with cestodes (3.5%) and mixed infections were found to be moderate (20.01%). Host wise prevalence of parasitic infection has shown highest in the case of cattle recording 43.03%, followed by 40.8% in buffaloes, 29.4% in sheep, and 21.4% in goats. Total six varieties of parasites were recorded, the predominant being Haemonchus (Strongyle group) (29.25%), followed by Paramphistomum (25.5%), Fasciola (11.9%), Strongyloides (7.6%), Moniezia (3.5%) and Trichuris (2.2%). Season wise data on prevalence showed, high rate of infection in summer season (32.0%) when compared to winter (30.2%) and rainy (29.9%) seasons. Further studies are needed to design a rational for sustainable management of GI parasite infections in domestic animals of local regions.

“…In Nigeria, the most common Тrichuris species in goats was Т. оvis (72.5%), while Т. globulosa was rarer (38.3%) (Nwosu et al, 1996). In certain regions of Sudan, Т. globulosa was observed only in 0.1% and 0.6% of studied sheep and goats, respectively (Almalaik et al, 2008). The Тrichuris species parasitizing in sheep in Ukraine are Т. оvis (most common, abundance index 3.4 specimens), T. skrjabini (less common, abundance index 2.2 specimens), and Т. globulosa (the rarest, abundance index 0.6 specimen) .…”

Biological specifics of Trichuris оvis Abildgaard, 1795 and T. globulosa Linstow, 1901 parasitizing domestic sheep were analyzed enhancing the species identification of these nematode species. The embryonic development of nematodes was timed, survival of embryonic stages was determined taking into account their morphological and metric specifics in laboratory culture. Trichuris eggs were isolated from gonads of adult female nematodes collected from caeca of dissected sheep. Then the eggs were cultured at optimal temperature to the formation of eggs with mobile larvae. Six morphologically distinct stages of embryogenesis were established in T. оvis and T. globulosa nematodes. The protoplast stage lasted from the 1st to the 12th day in T. оvis and to the 18th day in T. globulosa. Blastomeric formation occurred from the 3rd to the 18th day in T. оvis and from the 3rd to the 21st day in T. globulosa. Bean-shaped embryos formed from the 6th to the 21st day in T. оvis, and from the 9th to the 30th day in T. globulosa. Tadpole-like embryos developed from the 12th to the 24th day in T. оvis and from the 18th to the 33rd day in T. globulosa. Larvae formed in eggs of T. оvis from the 18th to the 27th day, and in eggs of T. globulosa from the 21st to the 36th day. Mobile larvae formed from the 21st to the 30th day in T. оvis, and from the 30th to the 39th day in T. globulosa. At 27 °С, mature eggs with mobile larvae developed in 30 days in T. оvis and in 39 in T. globulosa. The egg survival in laboratory culture was 84.3 ± 4.2 % and 76.3 ± 1.5%, respectively. Developmental changes of metric parameters in Trichuris nematode eggs (length and width of eggs, plug length, eggshell thickness) were species-specific.

“…The prevalence of T. colubriformis in sheep (65.7%) and goats (61.1%) was lower compared to the 83.5% and 77.5% prevalence reported for sheep and goats respectively, by Aragaw and Gebreegziabher 23 from Hawassa town. It was much higher when compared within the prevalence of 14.7% and 24.4% recorded for T. colubriformis in sheep and goats, respectively, in the Sudan 26 and 16% for sheep in Iran. 27 The prevalence of B. trigonocephalum in sheep (43.6%) and goats (56.4%) was lower compared to 50.9% for sheep but higher when compared the 38% prevalence reported for sheep and goats by Aragaw and Gebreegziabher 23 from Hawassa town.…”

Purpose: Although helminthiasis have been recognized as health constraints of small ruminants, there was no study conducted to reveal their types and burden in goats and sheep slaughtered at Bishoftu, Ethiopia. Hence, this study is aimed to evaluate the current status of helminth parasites and estimate its burden in study animals. Methods: The study was carried out from November 2016 to April 2017 to identify the species and also to estimate the burden of small intestinal parasitic helminth in goats and sheep using a standard worm recovery procedure. The study animals were 230 goats and sheep slaughtered at Bishoftu Elfora export abattoir during the study period. Results:The study revealed that the overall infection rate was 83.5%. Among 105 samples taken from sheep, 87.6% were positive, whereas 100 (80%) of 125 examined samples from goats were positive for helminth parasites. There was no statistically significant difference (p>0.05) between the species. However, age and animal origin considered as a risk factor indicated statistically significant differences (p<0.05). In sheep, the prevalence of Trichostrongylus colubriformis, Bunostomum trigonocephalum, and Moniezia expansa was 69 (46.9%), 34 (43.6%), and 51 (52.6%), respectively, while the prevalence of Trichostrongylus colubriformis, Bunostomum trigonocephalum, and Moniezia expansa in goats was 78 (53.1%), 44 (56.4%), and 46 (47.4%), respectively. Conclusion:This study revealed a high infection with parasitic helminths. Thus, effective control and prevention methods are necessary to minimize their effects on animals as well as the economy.
