(A)採血用酵素聯結免疫吸附試驗試劑偵測(B)The kit used to detect all ALV-positive chickens in breeder flocks is very important for efficiently controlling AL. Although commercial ELISA kits have been suggested to be effective(C)因為有不同分群,內外源的亞群分不同,其中 E 亞群為內源性病毒,J 亞群為外源性和內源性的重組病毒。(D)The results showed that the positive rate of p27 was 100% for the swabs and 40% for virus isolation. Surprisingly, PCR and sequence analysis revealed that the env gene of ALV in these positive samples belonged to the novel subgroup K (ALV-K).參考:https://birddise.nvri.gov.tw/fmodule/disSheet.aspx?id=DG%2FL8Jr%2BgxE%3D參考:Detection of ALV p27 in cloacal swabs and virus isolation medium by sELISA參考:http://ntur.lib.ntu.edu.tw/bitstream/246246/28725/1/922313B002128.pdf
