To understand the infection of main internal parasites in yaks, total of 402 fecal samples of yaks were collected from Hongyuan county in Aba prefecture and Litang county in Ganzi prefecture, the morphological characteristics of 4 kinds of internal parasitic eggs or oocysts were observed and the numbers of them were counted using the modified Liao's counting method. The results showed that in yaks of Hongyuan county, the average infection intensities of EPG or OPG of nematodes, cestodes, trematodes and coccidian were 11.59, 23.77, 42.45 and 14.72, respectively, and the total number of infections was 92.53 (48.91 to 154.90); The average infection rates of eggs or oocysts of these 4 kinds of parasites were 18.01%, 36.62%, 44.68% and 17.37%, respectively, and the total infection rate was 76.39%, which proved that trematodes was the dominant parasitic species and cestodes was also an important one in this area. In yaks of Litang county, the average infection intensities of EPG or OPG of nematodes, cestodes, trematodes and coccidian were 52.38, 13.10, 20.24 and 1.19, respectively, and the total number of infections was 86.90, the average infection rates of eggs or oocysts of these 4 kinds of parasites were 52.38%,19.05%,23.81% and 2.38%, respectively, the total infection rate was 78.57%, which proved that nematodes was the dominant parasitic species in this area. The infection patterns of internal parasitic eggs or oocysts in yaks in Hongyuan and Litang county were all mainly the single and double infection, the sums of these two patterns were 69.31% and 78.57%, respectively, which accounted for 90.73% and 100% of the total infection rate, respectively. The results in this paper showed that the parasitic disease in yaks was still an important disease harmful to yak production and herdsman health, meanwhile these results enriched the epidemiological data of the internal parasitic disease of yaks in Northwest plateau of Sichuan province and provided a theory basis for prevention and control of parasitic diseases in yaks in this area. 相似文献

An epizootiological survey of leishmaniosis, coccidiosis and parasitic helminths in 67 foxes (Vulpes vulpes) was conducted in Guadalajara (central Spain). Examination for parasitic protozoa revealed prevalences of 74% Leishmania (determined by molecular methods) and 2.9% coccidia oocysts (fecal flotation). Survey of parasitic helminths (fecal flotation/necropsy) demonstrated the presence of nine species, including six nematodes, two cestodes and one trematode. Nematodes were the most common parasites of foxes, followed by cestodes and trematodes. Greater levels of nematodes like Uncinaria, with a free-living stage in its life-cycle, were found in foxes in areas where moist soils were likely to exist, in contrast to areas of semiarid characteristics, where Toxascaris leonina or Trichuris vulpis were predominant. With regard to helminths of importance as human pathogens, trichinoscopy revealed the presence of a relatively high number of foxes (8.9%) infected with Trichinella spiralis. Finally, Toxocara canis infection was less frequent (4.4%) than trichinellosis. 相似文献

【目的】调查广东省内部分地区马匹寄生虫感染情况,探索区域内马匹寄生虫感染优势虫种、感染情况和耐药情况,为区域内马肠道寄生虫病的防治提供参考。【方法】采用饱和食盐溶液漂浮法和饱和蔗糖溶液漂浮法对广东省内7个城市24个马术俱乐部375份新鲜马粪样品进行处理,光学显微镜下观察虫卵/卵囊的形态结构特征并进行分类,并根据麦氏计数法计算每克粪便中虫卵/卵囊数（EPG）,统计感染率和感染强度。对EPG＞500的阳性样本进行粪便虫卵减少量计数试验（FECRT）,以评估各马术俱乐部流行寄生虫耐药情况。提取5份＜1岁幼驹的粪便样本DNA,利用巢式PCR检测样品是否存在隐孢子虫感染。【结果】375份样品中有120份样品呈寄生虫虫卵/卵囊阳性,总感染率为32.00%。共检出4种肠道寄生虫,分别为圆线虫、马副蛔虫、类圆线虫和马蛲虫,总感染率分别为30.40%、3.70%、0.80%和0.30%。1~4岁马匹感染率显著高于其他年龄段（P＜0.05）,但不同性别马匹寄生虫感染情况无显著差异（P＞0.05）。受调查马匹感染强度以低排卵（EPG＜200）为主,占马匹总数83.47%。FECRT结果显示,样本所在马术俱乐部常用驱虫药（主要成分为伊维菌素、阿苯达唑）有效,未见耐药现象。5份＜1岁幼驹的粪便样本隐孢子虫巢式PCR检测均为阴性。【结论】广东省部分地区马术俱乐部道寄生虫防控情况总体良好,区域内各马术俱乐部寄生虫防控效果存在差异,建议区域内各马术俱乐部加强马肠道寄生虫监测工作,依据本场监测情况合理用药,避免场内流行寄生虫对所用驱虫药物产生耐药性。 相似文献

Between January 1999 and December 2000 faecal samples from 16264 cattle at 12 dipping sites in the highveld and nine in the lowveld communal grazing areas of Zimbabwe were examined for gastrointestinal (GI) nematode and cestodes eggs, and coccidia oocysts. Strongyle larvae were identified following culture of pooled faecal samples collected at monthly intervals. The effects of region, age, sex and season on the prevalence of GI nematodes, cestodes and coccidia were determined. Faecal egg and oocyst counts showed an overall prevalence of GI nematodes of 43%, coccidia 19.8% and cestodes 4.8%. A significantly higher prevalence of infection with GI nematodes, cestodes and coccidia was recorded in calves (P < 0.01) than in adults. Pregnant and lactating cows had significantly higher prevalences than bulls, oxen and non-lactating (dry cows) (P < 0.01). The general trend of eggs per gram (epg) of faeces and oocysts per gram (opg) of faeces was associated with the rainfall pattern in the two regions, with high epg and opg being recorded during the wet months. The most prevalent genera of GI nematodes were Cooperia, Haemonchus and Trichostrongylus in that order. Strongyloides papillosus was found exclusively in calves. Haemonchus was significantly more prevalent during the wet season than the dry season (P < 0.01). In contrast, Trichostrongylus was present in significantly (P < 0.01) higher numbers during the dry months than the wet months, while Cooperia and Oesophagostomum revealed no significant differences between the wet and dry season. These findings are discussed with reference to their relevance for strategic control of GI parasites in cattle in communal grazing areas of Zimbabwe. 相似文献

Guinea fowl from different regions of Bashkir Autonomous Soviet Socialist Republic (BASSR) were examined for helminths. Of the 547 fowl examined, 451 (82.4%) harboured at least one species of helminth. A total of 56,772 helminths were collected and classified. Of this number seven were found to be trematodes, 25 cestodes and 56,740 nematodes. Five species of helminths were identified. Amongst infected birds, trematodes were present in three (0.7%), cestodes in eight (1.8%) and nematodes in 451 (100%). Of all recorded helminths, the incidence of Heterakis gallinarum (Gmelin, 1790) was highest. Pre-patent periods for seven species of trematodes were observed in guinea fowl for the first time. 相似文献

The range and infestation intensities of gastrointestinal parasitic nematode species depend on the type of swine production system. The present study focused mainly on nematodes of veterinary importance in scavenging pigs in Burkina Faso, and aimed at determining the prevalence of gastro-intestinal nematode parasites by means of faecal egg per gram (EPG) counts. Between November 2001 and October 2002, faecal samples from 383 pigs of different sexes and ages (< 5 months, 5-12 months and > 12 months) were collected from the rectum and examined for gastrointestinal nematodes parasites using the Mc Master method. Of the 383 pigs examined, 91% were infected by one or more parasites. Ascaris suum (40%; 100-1 400 EPG) was the most prevalent parasite followed by Strongyloides ransomi (21%; 100-4200 EPG), Oesophagostomum spp. (18%; 100-1000 EPG), Hyostrongylus rubidus (11%; 100-1 800 EPG), Globocephalus spp. (10%; 100-400 EPG) and Trichuris suis (1 %; 100-200 EPG). The prevalence was significantly higher in female pigs (n = 239) than in males. In addition, females excreted significantly (P < 0.05) more eggs in their faeces than males, except in the case of Globocephalus spp. The age of the animal had no effect on the prevalence of A. suum whereas there were significant differences in age categories concerning S. ransomi, H. rubidus, Oesophagostumum spp. and Globocephalus spp. Unexpectedly, the high prevalence of these common parasites was not accompanied by elevated EPG values, which suggests the existence of moderate infestations. The present work indicates that the common nematode infestations in pigs do not necessarily need a systematic herd anthelmintic treatment, as only a small number of worms is required to induce immunity. A further study is needed to formulate appropriate and cost-effective strategies for the control of gastro-intestinal nematode parasites in pigs in Burkina Faso. 相似文献
