  Krakatau which now consist of four islands has been studied intensively especially to learn the colonization of the plants after the great eruption.Orchid is one of the earliest vegetation occupied the island and in four island the number of the orchid species is increased.With the wind dispersal characters orchid seed easily spread especially in Rakata island.As the seeds able to float far away the origin of the seeds is often from a long distance.Observation on orchid up to 2008,32 terrestrial and 41 epiphytic orchid species found in Krakatau islands including 2 Jawa endemic species: Dendrobium tenellum and Eria verruculosa.

旋毛虫病是危害十分严重的一种食源性人兽共患寄生虫病。旋毛虫感染可以致使宿主出现强烈的免疫抑制,然而参与这种抑制作用的关键蛋白分子及其机制仍不明确。目前有关旋毛虫免疫逃逸相关基因的研究薄弱,而寄生虫丝氨酸蛋白酶在入侵宿主组织和逃避宿主免疫应答中发挥重要作用,成为寄生虫免疫逃逸研究的热点。本实验室通过构建旋毛虫3日龄成虫cDNA文库及免疫学筛选成功获得一条高丰度和强抗原性的丝氨酸蛋白酶基因Zh68,W
隐孢子虫病(Cryptosporidiosis)是由隐孢子虫(Cryptosporidium)引起的呈世界性分布的人兽共患寄生虫病,能引起人和动物的消化吸收功能障碍,导致动物腹泻和隐形感染,临床表现以腹泻为主。隐孢子虫主要通过粪-口途径传播,亦可通过直接接触或食入污染的食物或饮水进行传播。隐孢子虫可单独致病,亦可与其他病原混合感染发病,是婴幼儿、免疫功能抑制者、免疫功能缺陷者等高危人群的主要致死因

2012年6月-10月,本课题组在对黑龙江省部分地区淡水鱼类进行华支睾吸虫囊蚴感染情况调查时,在麦穗鱼体内发现了一种与华支睾吸虫囊蚴形态相似但结构却不同的囊蚴,因此,我们采取形态学观察、分子生物学和动物接种的方法对该吸虫囊蚴进行了鉴定.显微镜观察发现该种囊蚴呈圆形或类圆形,大小平均为0.156-1.188mm×0.138-0.170mm;具双层囊壁,囊壁厚度为5-19μm,是华支睾吸虫囊蚴囊壁的4
