Lyme disease also infects wolves , and heartworm can reduce a wolf 's endurance by restricting blood flow to the lungs .
莱姆病也会在狼群中传染，犬恶丝虫能够限制狼的血液流到肺部。
Protection in vaccinated individuals will wane after a year or two , so protection against lyme disease in previously vaccinated people will be nonexistent .
接种疫苗的个体在一到两年后预防效果就会衰退，所以之前接种过疫苗的人群并不能抵御莱姆病。
In clinical trials , vaccine efficacy was 49 % after 2 doses for those with definite lyme disease and 76 % after the third dose .
在临床试验中，对于确定的莱姆病患者，接种2剂疫苗效率达49%，3剂则达76%。
Diseases like malaria ( spread by mosquitoes ) , plague ( by fleas ) and lyme disease ( by ticks ) are predicted to surge as the carriers enjoy climate-related conquests of territory .
So noxious species of ants and bees are marching northwards across america , ticks carrying lyme disease are proliferating in scandinavia and tropical highlands around the world are witnessing an invasion of mosquitoes carrying malaria , dengue fever and japanese encephalitis .
