| bovine leukemia virus infection in taiwan: evaluation of the enzyme-linked immunosorbent assay and agar gel immunodiffusion test. | i evaluated an enzyme-linked immunosorbent assay (elisa) and agar gel immunodiffusion (agid) test simultaneously for the detection of bovine leukemia virus (blv) antibodies. total 1,293 serum samples were tested for elisa and agid test and the results were compared. the results of elisa and agid agreed by 1,156 out of 1,293 (89.4%). all of agid-positive 356 sera were positive by elisa. however, of 451 elisa-positive sera, 95 sera were either negative or equivocal by agid test. eleven animals whi ... | 1991 | 1668244 |
| development of a recombinase polymerase amplification lateral flow dipstick (rpa-lfd) for the field diagnosis of caprine arthritis-encephalitis virus (caev) infection. | caprine arthritis-encephalitis (cae) in goats is a complex disease syndrome caused by a lentivirus. this persistent viral infection results in arthritis in adult goats and encephalitis in lambs. the prognosis for the encephalitic form is normally poor, and this form of the disease has caused substantial economic losses for goat farmers. hence, a more efficient detection platform based on recombinase polymerase amplification (rpa) and a lateral flow dipstick (lfd) was developed in the present stu ... | 2017 | 28159666 |
| bovine leukemia virus infection in taiwan: epidemiological study. | we conducted a seroepidemiological survey for antibodies to bovine leukemia virus (blv), by using agar gel immunodiffusion technique, in dairy cows, water buffaloes, and yellow cattle throughout taiwan. the positive reactors were 8.4% (376/4,459) in 1985 and 5.8% (1,277/22,190) in 1986, in 15 prefectures and 7 cities. relatively high infection rate appeared in the northern and southern areas of taiwan. positive reactors increased gradually with age. the incidence of positive antibodies was 2 to ... | 1991 | 1653035 |
