the isolation of leptospira interrogans serovar pomona and related serological findings associated with a mixed farming unit in the transvaal.	this is the first known isolation in the republic of south africa (rsa) of the serovar pomona from the organs of porcine foetuses as well as from the renal lymph nodes of slaughter pigs showing chronic nephritis. in addition, the serovar pomona was isolated from the kidneys of 87.5% of the slaughter pigs examined. the success of these isolations was attributed in part to the refining of 2 existing isolation techniques which complement each other. using the microscopic agglutination test, serum s ...	1987	3627726
three case studies involving leptospira interrogans serovar pomona infection in mixed farming units.	three case studies involving leptospira interrogans serovar pomona outbreaks within mixed farming systems in south africa are described. on 2 farms, pigs constituted the main enterprise with cattle and sheep of secondary importance. on each of these 2 farms, abortion due to l. pomona in sows was confirmed by culture, and antibody titres to pomona were detected in cattle, sheep, horses and dogs. on the 3rd farm, a piggery was of secondary importance to cattle farming. abortion and death in cows o ...	1999	10855820
observations on three outbreaks of leptospira interrogans serovar pomona infection in lambs.	sickness and deaths associated with leptospirosis were reported in three lamb flocks in the manawatu region. the clinical, pathological and serological features of leptospiru interrogans serovar pomona infection are described. the mucous membranes of affected animals were pale and jaundiced. haemoglobinuria, haemoglobinaemia and centrilobular hepatocellular necrosis were also consistent findings. all clinically sick lambs had very high titres in the microscopic agglutination test for l. pomona. ...	1994	16031763
multiple-locus variable-number tandem repeat analysis (mlva) of leptospira interrogans serovar pomona from argentina reveals four new genotypes.	outbreaks of leptospirosis occur regularly in argentina, but little is known about their epidemiological relationships. we have analyzed the genetic diversity of a collection of 16 strains of leptospira interrogans serovar pomona isolated from animals and humans in argentina during the past 45 years. genotyping was performed by multiple-locus variable-number tandem repeat analysis (mlva) using the loci vntr4, vntr7, vntr9, vntr10, vntr19, vntr23 and vntr31, as described by majed et al.

prevalence of pathogenic leptospira spp. in sheep in a sheep-only abattoir in new zealand.	to determine the prevalence of the two most commonly diagnosed pathogenic leptospira spp. serovars, hardjobovis and pomona, in sheep in a sheep-only abattoir in new zealand, and to determine the prevalence of kidneys which were leptospire culture-positive collected from sheep seropositive or seronegative to the microscopic agglutination test (mat).	2008	18690252
are white-spot lesions in kidneys in sheep associated with leptospirosis?	to determine the association between white-spot lesions in kidneys and serological and cultural prevalence of leptospirosis in sheep, and to evaluate the diagnostic value of these lesions in individual sheep and lines of sheep at slaughter as indicators of past or current episodes of leptospirosis.	2009	19252540
