We recently had the opportunity to discuss with small ruminant veterinarians the needs of the sheep and goat sectors in terms of laboratory testing. They told us that some of your are interested in having a serological test for Brucella ovis. For now, Biovet is outsourcing the Brucella ovis Ab ELISA test to a US […]


There are currently four recognized species of porcine Circovirus: PCV1, PCV2, PCV3 and more recently PCV4. PCV2 is the species of the greatest clinical importance. PCV2 strains are currently classified into 8 genotypes (from 2a to 2h) based on differences in the capsid gene (ORF-2). For several years, Biovet has been offering identification of genotypes […]


Neospora caninum (hereinafter Neospora) is a unicellular parasite (protozoan). It is one of the leading agents of infectious abortions in cattle. Neospora has a complex cycle with several species of canids as definitive hosts and a wide variety of species, including cattle, as intermediate hosts. In cattle, Neospora is transmitted mainly transplacentally (vertically) from the […]


As you are certainly aware, Enzootic bovine leukosis (EBL) is the subject of a new prevalence study by Les Producteurs de lait du Québec (PLQ) using serological testing of bulk tank milk. In addition, it is the theme of a new PISAQ campaign orchestrated by the MAPAQ and the AMVPQ and intended to raise producers’ […]


In cattle, especially young ones, infectious bronchopneumonia is a major problem. While herd management and raising conditions are important risk factors, infectious agents ultimately are responsible for these pathologies. Thus, several viruses such as BRSV, BVDV, BoHV1, BCoV, BPIV-3 and IVD, as well as mycoplasmas (especially Mycoplasma bovis), have the ability to damage the respiratory […]


We were recently questioned about the prevalence of agents of intramammary infections in cattle. We made a partial assessment based on the samples examined at Biovet in January 2022 (n = 1,036). Below you will find the distribution of the main agents (Figure 1) and of the different species of Staphylococcus spp (Figure 2). At […]


Salmonella spp infections are a major concern for both herd and public health. In cattle, salmonellosis can be caused by different serotypes such as Typhimurium, Dublin, Newport, Montevideo, Muenster, Cerro, Muenchen, etc. (Gutema et al, 2019, Hong et al, 2016). Typhimurium serotype is most common in many species. Dublin serotype adapts well to cattle in […]


The Mycoplasma hyopneumoniae ELISA Oxoid/Dako kit, which many considered the reference in Mycoplasma hyopneumoniae serology, became unavailable in 2020 before being permanently withdrawn from the market in 2021. We have recently compared 3 serological assays that could possibly replace the Oxoid/Dako test i.e.: IDEXX ELISA test, IDEXX M. hyo Ab www.idexx.com/en/livestock/livestock-tests/swine-tests/idexx-m-hyo-ab-test Hipra ELISA test, CIVTEST® […]


Following the PRRS Forum organized by the CRIPA and the PRRS workshop held by the AVIA, we received questions regarding two diagnostic techniques and found it useful to give a brief update. CLAMP sequencing When a sample contains a mixture of PRRSV strains, sequencing by the Sanger method is usually able to sequence only one […]
