The epidemiological interpretation of serological responses to leptospiral serovars in sheep.
Serum samples were examined for evidence of leptospiral agglutinins from 928 sheep from 45 lines and kidneys from 12 of these lines for evidence of leptospiral infection. All sheep had been submittedExpand
Genetic characterization of pathogenic Leptospira species by DNA hybridization.
A total of 66 serovars of potentially pathogenic Leptospira species were examined by slot blot hybridization, and 57 of these serovars were classified in six DNA homology groups. In cases in whichExpand
Observations of leptospirosis in farmed deer.
AIMS Slaughterhouse and on-farm surveys were undertaken to investigate some aspects of leptospirosis (Leptospira interrogans) in farmed deer in the lower North Island of New Zealand. METHODS BloodExpand
A serological study of leptospirosis in domestic deer in New Zealand.
A total of 1296 free-living mammals and birds of 12 species was examined for serologic and bacteriologic evidence of leptospiral infection. Endemic infection with serovar ballum was found in severalExpand
Restriction endonuclease analysis of Leptospira interrogans serovar hardjo isolates from cattle.
The genomes of 253 strains of Leptospira interrogans serovar hardjo were examined by restriction endonuclease analysis of their DNA. The strains had been isolated from cattle at an abattoir (190),Expand
Respiratory disease in foals and the epizootiology of equine herpesvirus type 2 infection.
The epizootiology of equine herpesvirus type 2 (EHV-2) infection was investigated in Thoroughbred foals on a stud farm which in previous years had suffered economic loss due to respiratory disease.Expand
Fifty years of leptospirosis research in New Zealand: a perspective
Abstract Extract It is not known when pathogenic leptospires first became established in New Zealand. The first land mammals to arrive in this country about 1,200 years ago were human beings, dogsExpand
Seasonal prevalence of thermophilic Campylobacter infections in dairy cattle and a study of infection of sheep.
A total of 273 rectal swabs from dairy cows were cultured for Campylobacter jejuni/coli. The isolation rate was 17/72 (24%), 33/106 (31%) and 11/95 (12%) during summer, autumn and winterExpand
Identification of Leptospira serovars by restriction-endonuclease analysis.
Strains of Leptospira interrogans were examined by restriction-endonuclease analysis. Serovars hardjo and balcanica gave patterns that differed from each other, and from those of other members of theExpand
