subspecies (MAP) is endemic in the Dutch dairy goat population causing economic loss, and negatively influencing welfare. Moreover, there are concerns about a potential zoonotic risk. Therefore the industry's objectives are to decrease MAP prevalence, limit economic losses as well as reduce the concentration of MAP in (bulk) milk.

The aims of our study were to calculate the most appropriate cut-off value for milk samples in a serum-validated subsp. (MAP) ELISA and to analyze MAP ELISA responses in milk samples from vaccinated and nonvaccinated dairy goats in the Netherlands. Analyzed herds were representative for location and herd size of dairy goat herds in the Netherlands.

Article Synopsis
  • * Out of 90 dairy goat farmers approached, 58% participated, revealing a seroprevalence of 13.3% in the goat population, with 61.5% of farms having at least one infected animal.
  • * The study found that having cats (more than 4 significantly increases risk) and the average age of goats are key risk factors for T. gondii positivity, with the ELISA test proving to be accurate in detecting the infection.

Schmallenberg disease has emerged in North-Western Europe in 2011 and has since spread widely, even across the European borders. It has the potency to infect many, mainly ruminant, species, but seems to lack zoonotic potential. Horizontal transmission occurs through various Culicoides biting midges and subsequent trans-placental transmission causes teratogenic effects.

In the period from 2005 to 2009, Coxiella burnetii was a cause of abortion waves at 28 dairy goat farms and 2 dairy sheep farms in the Netherlands. Two years after the first abortion waves, a large human Q fever outbreak started mainly in the same region, and aborting small ruminants were regarded as most probable source. To distinguish between infected and noninfected herds, a surveillance program started in October 2009, based on PCR testing of bulk tank milk (BTM) samples, which had never been described before.
