寄生虫

Viruses are obligate, intracellular parasites that must enter another cell in order to multiply.

病毒是obligate，细胞内的寄生虫，必须进入另一个细胞以繁殖。

Successful host–host transmission is critical for the survival of obligate, intracellular parasites.

成功的主人–主人传输对生存是紧要关头的使负义务，intracellular 寄生虫。

Obligate parasites are totally dependent upon their hosts for survival and will die without their host.

专性寄生虫则完全依赖于他们的宿主生存，没有了宿主，他们也就将濒临死亡。

Oldfield, who is the senior author of the paper, had spent decades exploring this pathway, which has implications for the treatment of some cancers, as well as fungal and parasitic diseases.

作为本文的主要作者之一，Eric Oldfield曾花了数十年来探讨这个路径，这已影响到某些癌症以及真菌和寄生虫病的治疗。

Suramin has long been used to treat human trypanosomiasis and onchocerciasis, but since the recent years has received attention as an antitumor drug which has some inhibitory effect on the proliferation ,invasion and metastasis of some malignant tumor cells in vitro and in vivo.

苏拉明是一个用于治疗锥虫和/或盘尾丝虫感染的抗寄生虫药。近些年研究发现苏拉明对肿瘤细胞增殖、浸润、转移等有一定的抑制作用。体内外研究证实苏拉明对多种恶性肿瘤有抗肿瘤活性。

Parasitic infections, including onchocerciasis, should be considered in the differential diagnosis of pruritic eruptions in patients with a history of foreign travel...

Studies have shown that only about 2% of cats are shedding oocysts at any one time, and that oocyst shedding does not recur even after repeated exposure to the parasite.

研究表明，只有 2%的猫会排出一次胞囊，并且以后不再排出，即使猫体内仍有寄生虫。

It also offers graduate programs, in the following areas of specialization: cellular/molecular biology (i.e. molecular genetics, molecular evolution), organismic/environmental biology (i.e. aquatic biology, genetics, physiology, parasitology, microbiology, and ecology), and exercise science.

该系同时提供下列专业领域的研究生项目：细胞与分子生物学（例如分子遗传学，分子进化），有机体与环境生物学（例如水生生物学，遗传学，生理学，寄生虫学，微生物学，和生态学），和运动科学。

A useful test for diagnosis of infectious diarrheas is stool examination for ova and parasites.
