Abstract

A cross sectional study was carried out between June and August 2014 to establish the status of helminthosis and coccidiosis in nine purposefully selected small ruminant flocks in Mlandizi village in Melela ward, Mvomero district of Morogoro region, Tanzania. The study aimed at generating baseline information for vaccine trials against Haemonchosis in traditional flock in tropical areas. A total of 131 goats and 118 sheep that were screened for helminth eggs and coccidian oocysts using McMaster flotation techniques. In addition, copro-culture was carried out to obtain third stage larvae for parasite identification to the genus level based on morphological features shown in identification keys. Approximately, 54.2% and 52.7% of the goats (n=131) had helminth and coccidia infestations while, 67.8% and 49.2% of sheep were positive for the two parasite types, respectively. The average number (mean±SD) of eggs per gram (epg) in goats was 276±433 (range =100 to 2,100). In sheep, the average epg was 307±378, with values in individual animals ranging between 100 and 1,900. For the coccidian infestation, the average numbers of oocysts per gram (opg) in goats and sheep were 1180±2663 (range=100 to 100,300) and 1661±9563 (range= 100 to 28,300), respectively. Helminth genera detected in sampled animals were Haemonchus (50.7%), Trichostrongylus (29%), Oesophagostomum (16.4%), Cooperia (5.9%) and Strongyloides (3.4%). Monieza spp. was detected in sheep (5.8%) and goats (0.8%). Coccidial oocysts identified comprised of Eimeria caprina (20.6%), E. granulosa (16.2%), E. marsica (14.3%), E. ovinoidalis (12.4%), E. arloingi , (12.4%), for E. parva (16.2%) and E. christenseni (7.6%).

坦桑尼亚莫罗戈罗地区Melela区传统羊群山羊和绵羊的寄生虫病和球虫病现状

2014年6月至8月期间，在坦桑尼亚莫罗戈罗地区mvmero区Melela区的Mlandizi村进行了一项横断面研究，以确定9个小反刍动物群的蠕虫病和球虫病状况。这项研究的目的是为在热带地区传统畜群中开展针对血液病的疫苗试验提供基线信息。采用麦克马斯特漂浮技术对131只山羊和118只绵羊进行了蠕虫卵和球虫卵囊的筛选。此外，还进行了共培养，获得第三期幼虫，根据鉴定键显示的形态特征进行属级鉴定。131只山羊的寄生虫和球虫感染率分别为54.2%和52.7%，绵羊的寄生虫和球虫感染率分别为67.8%和49.2%。山羊平均每克(epg)产蛋数(平均值±SD)为276±433(范围为100 ~ 2100)。绵羊的平均epg为307±378，个别动物的epg值在100到1900之间。山羊和绵羊每克卵囊平均卵囊数分别为1180±2663(100 ~ 100,300)和1661±9563(100 ~ 28,300)。检出的蠕虫属依次为Haemonchus(50.7%)、Trichostrongylus(29%)、o食管口(16.4%)、Cooperia(5.9%)和Strongyloides(3.4%)。在绵羊(5.8%)和山羊(0.8%)中检出Monieza虫。经鉴定的球虫卵囊包括:红艾美耳球虫(20.6%)、细粒艾美耳球虫(16.2%)、marsica艾美耳球虫(14.3%)、卵黄艾美耳球虫(12.4%)、arloingi艾美耳球虫(12.4%)、parva艾美耳球虫(16.2%)和christenseni艾美耳球虫(7.6%)。由于研究动物中存在胃肠道寄生虫，因此需要根据受气候条件和变异趋势影响的寄生虫负担概况制定适当的干预措施。关键词:寄生虫，卵泡，卵泡，粪便培养
