Abstract

VHS virus shedding after experimental waterborne infection of rainbow trout was quantified by measuring virus infectivity in blood, faeces, and urine of catheterised fish. Virus shedding by urine with relatively high yields of infectious virus could be demonstrated during acute VHS until death, but not by faeces.

Trout, which were vaccinated against VHS or had survived the disease but showed no detectable humoral antibodies, may excrete infectious virus via urine for more than 30 days and without any signs of VHS after a secondary challenge infection. These results reveal the development of a carrier status of rainbow trout after VHS exposure.

虹鳟(Salmo gairdneri Rich)病毒脱落的几个方面经水传播感染病毒性出血性败血症(VHS)病毒后

通过检测虹鳟鱼血液、粪便和尿液中病毒的感染性，定量研究虹鳟鱼水媒感染后VHS病毒的脱落情况。在急性VHS直至死亡期间，病毒可通过尿液排出，传染性病毒的产量相对较高，但不能通过粪便排出。接种过VHS疫苗或存活过但未检测到体液抗体的鳟鱼，可通过尿液排出感染性病毒超过30天，并且在继发性攻击感染后没有任何VHS迹象。这些结果揭示了虹鳟鱼暴露于VHS后的载体状态的发展。
