Using culture, immunofluorescence and fetal serology, leptospiral infection was demonstrated in aborted, stillborn and weak lambs from nine out of 42 flocks investigated during the 1980 and 1981 lambing seasons. Three serogroups of leptospira, namely the Hebdomadis, Australis and Pomona serogroups, were implicated.
An unmatched comparative study is described to determine if routine clinical indicators are useful predictors for shoulder dystocia. Parity, maternal weight gain during pregnancy, and a history of a previous large baby and increased operative vaginal delivery rate were more often associated with shoulder dystocia. No other significant associations were… (More)
OBJECTIVE To review the prenatal diagnosis of apparently isolated severe ventriculomegaly (SVM) in a tertiary referral fetal medicine unit and report on perinatal and neurodevelopmental outcomes. METHODS All cases of isolated SVM referred to Fetal Medicine at the NMH between 2000 and 2008 were identified. Outcome information was obtained from detailed… (More)
Twenty sows were examined as part of an investigation into the relative importance of the genital and urinary tracts as sites of leptospiral persistence in pigs. The sows had previously either aborted leptospire-infected fetuses or aborted on farms where leptospire infection had been demonstrated in other litters. Leptospires belonging to the Australis… (More)
During an investigation of pig abortions and stillbirths in Northern Ireland, leptospires were isolated from 55 of the 78 litters examined. Strains belonging to four serogroups (Australis, Icterohaemorrhagiae, Hebdomadis and Autumnalis) were recovered but leptospires of the Australis serogroup accounted for 91 per cent of the isolates. Two serovars of the… (More)
