Prevalence of antibodies to Neospora caninum within central Queensland beef cattle

Prevalence and distribution of Neospora caninum in water buffalo ( Bubalus bubalis ) and cattle in the Northern Territory of Australia

“…The co-mingling of wild and domesticated water buffalo, wild dogs and domestic cattle leads to the assumption that a sylvatic cycle propagates N. caninum in the Northern Territory. N. caninum infection has previously been identified in the domestic beef cattle populations of Queensland at a seroprevalence of 14.9% [25]. Tropical dairy cattle herds in Queensland have shown a higher seroprevalence of between 23 and 34% [26], which is similar to the one reported from this part of Australia.…”

Neurological diseases of ruminant livestock in Australia. III: bacterial and protozoal infections

“…Substantial seropositivity to N. caninum was demonstrated in aborting cows, as well as evidence of reactivation of latent infections and congenital transmission. Approximately 15% of beef cattle tested in Queensland were seropositive to N. caninum , 50 and abortions attributed to N. caninum in northern NSW ranged from 14% to 36% between 1982 and 1994 51 . The first Australian isolate of N. caninum , from a calf, was characterised in 2002 52 …”

Serological evidence of Neospora caninum in alpacas from eastern Australia

“…Horizontal transmission is suspected to occur in cattle through contaminated feed and water with oocysts excreted in the faeces of canids, including domestic dogs, wild dogs and foxes . In Australia, alpacas mainly graze on grasslands close to cattle and dogs and these grasslands could be a source for horizontal transmission of infection to alpacas.…”
