      Simpson, Gregory; Marcotty, Tanguy; Rouille, Elodie; Chilundo, Abel; Letteson, Jean-Jacques; Godfroid, Jacques (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-03-29)
      Brucellosis is of worldwide economic and public health importance. Heifer vaccination with live attenuated <i>Brucella abortus</i> strain 19 (S19) is the cornerstone of control in low- and middle-income countries. Antibody persistence induced by S19 is directly correlated with the number of colony-forming units (CFU) per dose. There are two vaccination methods: a ‘high’ dose (5–8 × 10<sup>10</sup> ...

    • Immunostimulant Bathing Influences the Expression of Immune- and Metabolic-Related Genes in Atlantic Salmon Alevins 

      Figueiredo, Filipe; Kristoffersen, Harald; Bhat, Shripathi; Zhang, Zuobing; Godfroid, Jacques; Peruzzi, Stefano; Præbel, Kim; Dalmo, Roy Ambli; Xu, Xiaoli (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-09-29)
      Disease resistance of fish larvae may be improved by bath treatment in water containing immunostimulants. Pattern recognition receptors, such as TLR3, TLR7, and MDA5, work as an “early warning” to induce intracellular signaling and facilitate an antiviral response. A single bath of newly hatched larvae, with Astragalus, upregulated the expression of IFNα, IFNc, ISG15, MDA5, PKR, STAT1, TLR3, and ...

There is currently no information on bovine brucellosis sero-prevalence in South Sudan regardless of the economic, social and public health impact on populations. Therefore, for the first time in 33 years, we report the sero-prevalence of brucellosis in cattle and their herders. Furthermore, we characterize the ...

    • The serostatus of Brucella spp., Chlamydia abortus, Coxiella burnetii and Neospora caninum in cattle in three cantons in Bosnia and Herzegovina 

      Softic, Adis; Asmare, Kassahun; Granquist, Erik Georg; Godfroid, Jacques; Fejzic, Nihad; Skjerve, Eystein (Journal article; Tidsskriftartikkel; Peer reviewed, 2018-02-02)
      Dairy production in Bosnia and Herzegovina exhibits limited productivity, which may partly, be explained by extensive reproductive problems of non-infectious and infectious origin. Brucella spp., Chlamydia abortus, Coxiella burnetii and Neospora caninum are common infectious causes of decreased reproductive outcomes in cattle worldwide. Little is, however, known about the disease status of herds ...

    • Shedding of Brucella melitensis happens through milk macrophages in the murine model of infection 

      Jansen, Wiebke; Demars, Aurore; Nicaise, Charles; Godfroid, Jacques; Xavier, de Bolle; Reboul, Angeline; Al Dahouk, Sascha (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-06-10)
      Although shedding of zoonotic brucellae in milk has been demonstrated in natural hosts, these data are still missing for the standard murine infection model. We therefore analysed shedding kinetics and the niche of <i>B. melitensis</i> in murine milk. Pregnant Balb/cByJ mice were intraperitoneally infected with 10<sup>5</sup> CFU of the 16 M reference strain, a 16 M mCherry mutant or a human isolate. ...

    • The Story behind COVID-19: Animal Diseases at the Crossroads of Wildlife, Livestock and Human Health 

      De sadeleer, Nicolas; Godfroid, Jacques (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-04-27)
      A number of virological, epidemiological and ethnographic arguments suggest that COVID-19 has a zoonotic origin. The pangolin, a species threatened with extinction due to poaching for both culinary purposes and traditional Chinese pharmacopoeia, is now suspected of being the “missing link” in the transmission to humans of a virus that probably originated in a species of bat. Our predation of wild ...
