Isolation ofLeptospira interrogansserovargrippotyphosafrom a heifer in New South Wales

Prevalência e aspectos epidemiológicos da leptospirose bovina em rebanho leiteiro na microrregião de Goiânia - GO

“…A porcentagem de animais reagentes ao teste de SAM para cada sorovar está descrita na tabela 1. A predominância de reações aglutinantes para o sorovar wolffi (29,60%) também foi descrita anteriormente, no Estado de Goiás, por JARDIM et al (1978), que encontraram 50% de prevalência, e apareceu nos resultados de vários estudos de prevalência realizados no Brasil na década de 70: CORDEIRO et al (1975) (ABDOLLAHPOUR, et al 1996). Essa afirmativa não pode ser adotada para o rebanho da microrregião de Goiânia, que obteve prevalência de apenas 5,20% para hardjo.…”

Prevalence of antibodies to Leptospira serovars in beef cattle in central Queensland

“…Serovars other than hardjo and pomona that have been isolated from cattle in Queensland and New South Wales include australis, 1 zanoni, 2 celledoni 3 and grippotyphosa. 4 Furthermore, leptospirosis is an occupational hazard for meatworkers, dairyfarmers and others in animal associated occupations and frequently involves serovars other than hardjo and pomona. 5 This, and the recent isolation of other serovars from cattle, suggested the need for up-to-date seroprevalence data as a preliminary to assessing the roles of other serovars in bovine subfertility and the role of cattle as a zoonotic reservoir.…”

Laboratory Diagnosis of Bovine Abortions Caused by Non-Maintenance Pathogenic Leptospira spp.: Necropsy, Serology and Molecular Study Out of a Belgian Experience

“…The bovine abortuses selected for this study (116) were declared in southern Belgium (Walloon Region) between 27 August 2014 and 15 June 2015 and sampled within the framework of a national surveillance program of abortions in cattle. The study period relates to a time where unusual manifestations of congenital jaundice cases in bovine fetuses were firstly observed in Belgium [ 30 ]. In order to have equal representations of icteric and non-icteric abortuses, non-icteric cases were randomly selected among those declared in the same timeframe.…”

“…L. borgepetersenii serovar Hardjobovis and L. interrogans serovar Hardjoprajitno have been shown to be causes of reproductive losses worldwide [ 25 , 26 , 27 ]. Instead, knowledge of the disease caused by non-maintenance serovars, other than from serological surveillance, is poor and linked to anecdotal reports [ 28 , 29 , 30 ]. The pathogenesis of reproductive disease due to Leptospira spp.…”
