迄今所发现的抗生素已远远超过四千种,但对80多种原虫和近30种蠕虫有抗寄生虫活性的抗生素却为数极少。大多数抗生素对原虫的活性与对宿主的毒性之间的差别不大,因此实际使用的抗寄生虫抗生素不过几种。昭和20年代初,寄生虫曾经在我国蔓延过,由于集体验便、驱虫及卫生管理等的改善,患病率已显著减少。由于交通运输的发达,接触地区性特殊寄生虫的机会增多,从
To date, there are far more than four thousand antibiotics found, but very few antibiotics have antiparasitic activity against more than 80 protozoa and nearly 30 worms. Most antibiotics have little difference between their activity against protozoa and their toxicity to the host, so there are only a few actual antiparasitic antibiotics. In the early 1920s, parasites were once spread in our country. The prevalence rate has been significantly reduced due to the improvement of collective experience, deworming and health management. Due to the development of transportation, the chances of exposure to endemic parasites increase
