Wild animals in zoological gardens can predominately affected by various gastro-intestinal parasites. This study was therefore, conducted to determine occurrence, identify types and assess seasonal variation of gastrointestinal parasites in captive animals at the Zoological garden of Haramaya University. The study involved a retrospective investigation of zoo records and fecal examinations. Twenty two fecal samples were collected in December, 2013 from all the animals in the garden and examined using concentration and fecal culture techniques. Sampling was repeated after four months in April, 2014 to assess seasonal variations of the parasites. The result from the retrospective study showed death of 21 animals in the last five years. Fecal examination confirmed presence of gastrointestinal parasites with an overall mean prevalence rate of 73.8%. A total of 9 parasite taxa were identified of which 6 (66.67%) and 4 (33.33%) were helminths and protozoa respectively. No Cestode and Trematode species were recovered. <i>Trichuris spp.</i>, <i>Toxocara spp.</i>, <i>Strongyloides spp.</i>, <i>Toxascaris leonine</i>, <i>Passalurus ambiguous</i> and <i>Ascaridia spp.</i> were the helminth parasites observed in the garden. <i>Entamoeba spp.</i>, <i>Isospora spp.</i> and <i>Eimeria spp.</i> were the protozoan parasites encountered. No remarkable seasonal variation in parasitic infection was noticed in the garden. The study revealed occurrence of gastrointestinal parasites in the zoological garden, most of which are zoonotic and hence future studies are needed to determine risks of cross-transmission.展开更多
目的:比较野生、栽培(庭院及 GAP)种植的中药栀子中主要有效成分含量的差异。方法:采用 HPLC-DAD 法,同时在240,330,440nm 3个波长下对野生、栽培及 GAP 种植的中药栀子中4种主要有效成分的含量进行测定。结果:各有效成分在各自浓度范...目的:比较野生、栽培(庭院及 GAP)种植的中药栀子中主要有效成分含量的差异。方法:采用 HPLC-DAD 法,同时在240,330,440nm 3个波长下对野生、栽培及 GAP 种植的中药栀子中4种主要有效成分的含量进行测定。结果:各有效成分在各自浓度范围内线性关系良好;方法精密度、稳定性良好;平均回收率均大于98.1%;该方法下,样品在24 h 内稳定。野生栀子中栀子苷、栀子酸及氯原酸的含量明显高于栽培栀子,而藏红花素1的含量则低于栽培品。结论:采用多波长检测方法,同时对栀子中多种有效成分的含量进行检测,可以更全面地反映中药的物质信息,使得对不同种植方式的栀子药材的质量评价更科学、严谨。展开更多
