Occurrence of Gastrointestinal Parasites in Small Ruminants in the Central Part of Myanmar

Abstract

Gastrointestinal parasite infection in small ruminants remains one of the major economic losses caused by reduced productivity. A total of 380 faecal samples were taken from 280 sheeps in Magway and Pwintbyu Townships and 100 goats in Natmauk Township, Myanmar. Faecal flotation and sedimentation methods were carried out to detect the presence of parasitic infections. Faecal egg and oocyst counts were carried out using the McMaster technique. The overall occurrence of gastrointestinal parasites in small ruminants was 98.4% (374/380). The occurrence of gastrointestinal parasites in sheep (99.3%) was higher than that in goats (96%). The highest occurrence was found in Eimeria spp. (96%), followed by Trichostrongyle (77.1%), Trichuris spp. (35%), and Moniezia expansa (14%). The mixed infection rate was 84.8% (317/374), while a single infection was 15.2% (57/374). The mean eggs per gram (EPG) and oocysts per gram (OPG) of faeces were ranged from 50 to 600 and 50 to 29,800, respectively. Among the 4 nucleotide sequences isolated, one sequence was 94.10-94.47% similarity with Trichostrongylus colubriformis, reported from Laos, and three sequences showed 96.64-99.46% identity with Haemonchus contortus from Laos, China, India, and Mongolia. As gastrointestinal parasite infection in small ruminants was relatively high in the study area, the development of appropriate treatment and control measures should be provided to reduce production losses.

Morphological identification and phylogenetic analysis of Moniezia species isolated from sheep in Wasit province/ Iraq

“…The intermediate host of the Moniezia spp. is pasture mites, exposure of the ruminants to soil and grass will increase the chances of infection and the factors responsible for variations in the prevalence of different parasitic diseases might be the different climate and immune status of the individual animal (Zainalabidin et al, 2019;Win et al, 2020) . According to Moniezia spp.…”

Діагностична Ефективність Удосконаленого Способу Лабораторної Діагностики Стронгілятозів Органів Травлення Кіз

“…Тому більшість авторів вказують на те, що через високу вартість новітніх методів діагностики, найбільш обґрунтованими і маловитратними є методи копроскопічної діагностики. Застосовуючи такі методи, як біологічний матеріал використовують фекалії тварин, які досліджують з метою виявлення паразитичних яєць, личинок та фрагментів самих гельмінтів [16][17][18]. Існує кілька методів і їхніх модифікацій, які зареєстровані і стандартизовані.…”

First report on the molecular detection of Entamoeba bovis from the endangered wild water buffalo (Bubalus arnee) in Nepal

“…The protozoan Entamoeba spp. are critical zoonotic parasites that infect both animals and humans (Feng et al., 2018 ; Tachibana et al., 2013 , 2007 ; Win et al., 2020 ), and are transmitted among hosts through the ingestion of cysts in contaminated food, water or faeces (Matsubayashi et al., 2018 ). Major pathological illnesses caused by Entamoeba spp.…”

“…(Shrestha et al., 2018 ). However, such microscopic diagnostics are less effective because of a lack of sensitivity and specificity (Win et al., 2020 ). It is difficult and challenging for positive identification because of similar morphological characters among Entamoeba spp.…”
