Prevalence of gastrointestinal helminths of sheep in Sherpur, Bangladesh

Abstract

Objective: Gastrointestinal (GI) parasitic infection is a prime cause of failures in sheep production. This study was conducted to ascertain the prevalence of gastrointestinal (GIT) helminths of sheep in Sherpur district, Bangladesh. Besides, prevalence of helminthiasis in sheep also assessed considering age, sex, nutritional condition and rearing system. Materials and methods: In total, 106 rectal fecal samples of sheep were randomly collected and were examined for the presence of ova by using direct smear and Stoll's ova counting techniques during July to October, 2016. Eggs were identified on the basis of its size, morphology and other landmark features. Results: Out of 106 samples, 67.9% (n=72/106) revealed the presence of ova of different helminths. The prevalence of helminth infection was associated with Fasciola gigantica (11.3%; n=12/106), Paramphistomes (13.2%; n=14/106), Schistosoma indicum (3.8%; n=4/106), Moniezia sp. (3.8%; n=4/106), Strongyle-type (24.5%; n=26/106), hook worm (6.6%; n=7/106), Strongyloides sp. (12.3%; n=13/106) and Trichuris sp. (1.9%; n=2/106). Egg count per gram (EPG) was calculated which was ranged between 100 and 600. Parasitic counts in lambs, young and adult showed no significant variations (P=0.511) from one other. Infection was significantly (P=0.04) higher in poor body conditioned sheep (76.3 %) as contrasted to normal body conditioned sheep (57.4%). No significant variation (P=0.601) was noticed in infection rates between sexes. Females displayed a higher infection (70.0%) as compared to males (65.2%). In rearing system, the result was found statistically insignificant (P=0.247). Conclusion: Utterly, GI helminths are endemic at great levels among sheep in the study area. Also, their infestation differs within various age groups, sexes, nutritional condition and rearing system of sheep.

Prevalence of Haemonchus contortus Infections in Sheep and Goats in Nyagatare District, Rwanda

“…There were no statistically significant differences in the shedding of nematode eggs between male and female sheep ( Table 2 ). These results are in agreement with the findings of a study from Ethiopia [ 31 ] and Bangladesh [ 32 ]. In contrast, a significantly higher number of female than male goats had nematode eggs in their faeces.…”

Prevalence of Gastrointestinal Helminthes among Goats in and around Ranchi, Jharkhand, India

“…Nematodes were recorded to be of highest prevalence (62.37%) followed by trematodes (56.02%) and cestodes (47.63%) (Table 1 and Figure 1). Similar findings were reported by Gupta et al, in 2013;Poddar et al, Islam et al, Ahmed et al, Sanalkumar et al, and Sohail et al, in 2017 and in 2018 by Jena et al, The higher prevalence of gastrointestinal parasites in tropical, subtropical and also temperate climates could be attributed to their wide range of adaptability (Soulsby, 1966;Sanyal, 1998 andPoddar et al, 2017). Rainy season was recorded to have highest overall prevalence of 94.84% followed by 86.77% in winter and the lowest being recorded at 76.77% in the summer months (P<0.01) (Table 1and Figure 2).…”

“…4 to 9 months at 89.86% and more than 9 months at 75.75% (Table 1and Figure 3). Molla and Bandyopadhyay (2016), Poddar et al, (2017) and Jena et al, (2018) found similarly higher and lower rate of prevalence among younger age groups and adult animals, respectively. 0-3months age group was also recorded to have highest prevalence (79.67%) of nematode infection.…”

An epidemiological investigation of gastrointestinal parasites of small ruminants in Tangail, Bangladesh

“…These observations were found consistent with previous reports who recorded 65.6%, 63.3%, 63.5% prevalence in Bangladesh, Lahore and Islamabad, respectively (Ijaj et al, 2008;Gadahi et al, 2008;Hasan et al, 2011). However, this finding was comparatively lower than that reported by Poddar et al (2017) who indicated 67.4% overall prevalence in Sherpur District of Bangladesh. Notable that in the study areas, pineapple are prevalent and this pineapple are sometime ingested by ruminants.…”
