The role of experimenter familiarity in children's eyewitness identification.

Child eyewitnesses show a high false identification rate on target-absent (TA) lineups despite good performance on target-present (TP) lineups. One explanation is that children feel a social pressure to choose when presented with a TA lineup. We investigated whether experimenter familiarity would reduce social pressure and improve accuracy on TA lineups.

Yersiniosis in sheep due to Yersinia enterocolitica.

An outbreak of acute yersiniosis occurred amongst sheep transported from Inner Mongolia to Hunan Province in southern China. Morbidity was 41% and mortality of affected sheep was 34%. Eleven apparently identical isolates of Yersinia enterocolitica were obtained from liver, lung and skin lesions of affected sheep and all were biotype 3.

Serological response of sheep to plasmid-encoded proteins of Yersinia species following natural infection with Y. enterocolitica and Y. pseudotuberculosis.

A prospective study of the serological response to natural infection with Yersinia enterocolitica and Y. pseudotuberculosis was performed in an experimental flock of sheep. A preliminary investigation with immunoblotting techniques showed that lambs infected with virulent Yersinia spp.

Epidemiology of Yersinia pseudotuberculosis and Y. enterocolitica infections in sheep in Australia.

Infections with Yersinia pseudotuberculosis serotype III and Y. enterocolitica serotype O2,3 were found to be common in Australian sheep flocks. Transmission of Y.

Enteritis in sheep and goats due to Yersinia enterocolitica infection.

Yersinia enterocolitica biotype 5, serotype 02,3 was isolated from the intestine of 38 sheep and 8 goats submitted to the laboratory for disease diagnosis. Infected animals were usually young, had diarrhoea and were in poor condition or emaciated. A number were moribund or dead when submitted.
