Detection of JEV in pig herds with reproductive failure and quantification of reproductive disorders.
| Lab Method | Material | Result | Differential Diagnosis Intention | Reproductive Failure | Country | Reference |
|---|---|---|---|---|---|---|
| RT-PCR | Aborted fetuses | Detection | No | No quantitative data | China | [68] |
| RT-PCR | Sample of 37 CSF of aborted piglets | 5/37 | No | No quantitative data | China | [69] |
| ICISM, virus isolation, RT-PCR | Sample of 108 brain tissues of stillborn piglets | 20/108 | No | No quantitative data | China | [70] |
| RT-PCR | Sample of 3 brain samples of stillborn piglets | 3/3 | CSFV, PRRSV, PRV, PPV not detected | 30 sows with RF/200 sows (15%) | China | [64] |
| RT-PCR | 31 brain samples of stillborn piglets (all stillborn piglets of the farm) | 7/31 | No | 10 sows with RF/28 sows (36%), 2–5 sb/sow, 31 sb in total | India | [65] |
| RT-PCR | Sample of 8 brain samples of stillborn piglets | 8/8 | CSFV, PRRSV, PRV, PPV not detected | 37 sows with RF/128 sows (29%) | China | [66] |
| HIA on body fluids and virus isolation (unspecified method) | Aborted fetuses | Isolation on “some” fetuses | No | 50 sows with RF/320 sows (3 farms) (16%) | Japan | [50] |
RT-PCR—reverse transcription-polymerase chain reaction; ICISM—intracerebral inoculation of suckling mice; HIA—hemagglutination inhibition assay; CSF—cerebrospinal fluid; CSFV—classical swine fever virus; PRRSV—porcine respiratory syndrome virus; PRV—pseudorabies virus; PPV—porcine parvovirus; sb—stillborn; RF—reproductive failure (abortion or at least one stillborn piglet in the litter).
