The origins of the more irulent strains of Toxoplasma were first documented in a 2001 Science paper from Boothroyd's group; the researchers found that the recombination of two relatiely benign strains of Toxoplasma can result in a thousand-fold increase in their ability to cause serious disease.

Boothroyd等人在2001年《科学》的文章中记载了弓形虫毒性菌株的来源，他们发现将两种相对良性的弓形虫菌株重组后，新菌株的致病性呈千倍上升。

From an extensive molecular epidemiological surveillance around the H5N1 infected regions in the past several years, H5N1 viruses were isolated from the wild birds, eg. Bar-headed goose, brown-headed gull, great black-headed gull and common cormorant form Qinghai province and tree sparrow from henna province.

通过开展高致病性禽流感疫区的分子流行病调查，从野生鸟类分离到这种H5N1亚型的禽流感病毒，如从青海湖斑头雁、棕头鸥、渔鸥、鸬鹚，从河南的树麻雀等都分离到这种病毒。

Serious attention to the trypanosomes of mammals was drawn by the work of Timothy Lewis on the parasite of Indian rats, the importance of which was realized after Griffith Evans (1880) discovered the pathogenic trypanosome in horses and camels in India Trypanosoma evansi

Timothy Lewis对印度老鼠的寄生虫的研究引起了人们对于哺乳动物锥虫病的严重关注。Griffith Evans (1880)在印度发现马和骆驼身上的致病性锥虫之后，人们才认识到了哺乳动物锥虫病的重要性。
