Brucella canis is a zoonotic pathogen and the main causative agent of canine brucellosis. In the Netherlands, B. canis had previously only been detected in individual cases of imported dogs.

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.

Paratuberculosis infection is caused by (MAP). In the Netherlands, 75% herd level prevalence of caprine paratuberculosis has been estimated, and vaccination is the principal control strategy applied. Most goat dairy farms with endemic paratuberculosis systematically vaccinate goat kids in the first months of life with a commercially available whole cell MAP vaccine.

Sequence-based typing of has led to insights in the evolutionary developments of tularemia. In Europe, two major basal clades of subsp. exist, with a distinct geographical distribution.

Brucellosis is a zoonotic disease with terrestrial or marine wildlife animals as potential reservoirs for the disease in livestock and human populations. The primary aim of this study was to assess the presence of Brucella pinnipedialis in marine mammals living along the Dutch coast and to observe a possible correlation between the presence of B. pinnipedialis and accompanying pathology found in infected animals.

Single nucleotide polymorphisms (SNPs) are abundant in genomes of all species and represent informative DNA markers extensively used to analyze phylogenetic relationships between strains. Medium to high throughput, open methodologies able to test many SNPs in a minimum time are therefore in great need. By using the versatile Luminex® xTAG technology, we developed an efficient multiplexed SNP genotyping assay to score 13 phylogenetically informative SNPs within the genome of Bacillus anthracis.

Bacillus anthracis, the causative agent of anthrax, is a zoonotic pathogen that is relatively common throughout the world and may cause life threatening diseases in animals and humans. There are many PCR-based assays in use for the detection of B. anthracis.

Article Synopsis
  • Q fever is caused by the bacterium Coxiella burnetii and saw a major outbreak in the Netherlands starting in 2007, linked to small ruminants.
  • Researchers analyzed 126 positive samples from ruminants to identify the genetic make-up of C. burnetii, finding a unique genotype prevalent in goat and sheep herds tied to the outbreak area.
  • The similarity between the ruminant genotype and a human genotype further suggests a direct connection, indicating that this specific strain likely led to the Q fever epidemic in humans.

The bacterium Coxiella burnetii, which has a wide host range, causes Q fever. Infection with C. burnetii can cause abortions, stillbirth, and the delivery of weak offspring in ruminants.
