Project development stage: Stage 3 : Method has been set up, tested by some vet labs. Field samples are now being collected. We need some more budget to extend the number of farms investigated  to get data at a national scale.

Novel Diagnostic Test for Improvement of Udder Health and Bovine Mastitis Control (SpecCNS)
Improving bovine mastitis diagnosis and control
Project topic:
Bovine mastitis; dairycows; udderpathogens; milkquality; multiplex realtimePCR
Description: Mastitis remains the most common and costly disease in dairy cows worldwide requiring antibiotic treatment. Bovine Coagulase-negative staphylococci (CNS) have recently emerged as common bovine udder pathogens with a within-herd prevalencesranging from 10 to 60% . While 52 species and 28 subspecies are described, CNS are routinely only diagnosed on group level. It is well documented different CNS have different species-specific characteristics and can be classified into udder-adapted, opportunistic and environmental CNS or as virulent, protective against other udder pathogens and of no importance. A feasible and accurate CNS species-specific quantitative PCR is vital to discriminate harmless from harmful CNS, enable prudent treatment decisions and give necessary new insight into the impact and epidemiology of CNS infections. Integration of the new test in veterinary udder health management will become the basis to develop CNS specific control programs. Concerns about antimicrobial resistance and prudent use of antibiotics promote the implementation of selective dry cow treatment instead of treating all cows regardless of infectious status. Knowing CNS species specific pathogenicity factors and implementing this knowledge in diagnosis e.g. on samples at dry off, will reduce unnecessary dry cow treatments. There is no currently available diagnostic tool, which can isolate, identify and differentiate CNS on species level directly without pre-culture step. The hypothesis is that species-specific knowledge of the impact and epidemiology of CNS infections based on a fast and accurate multiplex quantitative PCR method (qPCR) can improve udder health management through efficient treatment, preventive strategies and reduction of antibiotic usage. The objectives are 1) to develop and validate a qPCR assay for detection of CNSspecies directly from milk samples without prior culturing and without the need for extra costs to cover the sampling equipment and storage, 2) evaluate the novel qPCR assay for identifying the most relevant pathogenicity factors of CNS species, 3) apply the qPCR assay in commercial herds to identify the epidemiological species-specific patterns from subclinical and clinical infections and to classify CNS species into “friendly = protective” and “non-friendly = harmful” for better decision making, and 4) evaluate the impact of implementing the qPCR assay in routine veterinary practice on udder health, antibiotic usage and milk quality.
Avantages of the innovation: The greatest effect of this proposal is developing a novel diagnostics that results in a better, quick, accurate and more targeted health advice to the dairy farmers and veterinarians so that fewer antibiotics and especially fewer broad-spectrum antibiotics are used. It is expected the antibiotic consumption to be lowered due to improved health and critical choice of animals for treatment based on evidence obtained in the project concerning. This ensures a high level of wellbeing in the cows and a targeted preventive effort is promoted with the new knowledge in the health advice. The proposed research project is an extension to my robust experience and qualifications in udder health and mastitis diagnostics, where I have identified and characterized the contagious and environmental mastitis pathogens using a wide variety of laboratory and potential biomarkers for bovine mastitis. The project will translate my experience and research into an innovative technology that can be used for improving mastitis control and also demonstrate its value in the dairy industry. There is no currently available diagnostic tool, which can isolate, identify and differentiate CNS on species level directly without pre-culture step. Thus, there is a necessity to develop, validate and apply a quick, accurate and species-specific PCR assay, which does not require a pre-culture step. Species differences in virulence characteristics could be the reason for difference in clinical expression between CNS species. Knowing CNS species specific pathogenicity factors and implementing this knowledge in diagnosis is vital e.g. testing at dry off will reduce unnecessary dry cow treatments. This is in line with the increasing international pressure by UN and FAO to reduce the use of antimicrobials in food production to minimize the emergence of antimicrobial resistance. Derived effects for society include less use of antibiotics in milk production, less risk of antibiotic resistance and less risk of
antibiotic residues in the milk. In connection with the reduction of the number of infected cows and the decrease in the tank cell number, an improved
milk quality is expected due to less secretion of bacteria in milk.
Potentiel market application: Optimization of the use of anthelmintics to the real field  conditions (in order to target the treatment molecule and dose vs parasites really encountered). Follow up of the parasitic pressure on the field and monitor the emergence of anthelmintic resistance.
Project development stage: The new multiplex qPCR test will provide benefits to the dairy industry in terms of milk quality and yield as well as to the cattle in terms of animal welfare. Additionally, there will be public health benefits resulting from reduced antimicrobial use. The project generates a multi-page output that forms the basis for commercialization. It is expected that the industrial partner to increase earnings by developing and selling new diagnostic Q-PCR kits. These are kits for use in the diagnosis of mastitis in cows and for the detection of mastitis bacterium in teat niches and in the stable environment. If the project succeeds in combining species detection for CNS and virulence and resistance genes, they will as the first qPCR methods in the world combines knowledge of causal agents with knowledge of antibiotic resistance. It is expected that the we develop two new qPCR diagnostic packages aimed at mastitis for better CNS identification and differentiating CNS subtypes and the other one for combined pathogenicity and resistance kit.

Description: We proved that randomly fragmented extracellular DNA of an organism is inhibitory to its own self. This discovery has led to an innovative approach to combating harmful organisms. Different tests done with heterologous DNA, and self DNA revealed that the action is highly species specific. While the self DNA is inhibitory, heterologous DNA acts as a source of nutrient. Patent : WO2014020624A2
Avantages of the innovation: The effect of extracellular self DNA opens new perspectives for a highly species specific inhibitory product for biological control, with significant economic and environmental advantages. Notably, the species specific action makes the invention important in combating specific organisms affecting animal health, with least side effects. The technology can be used in different life science domain too, as a panacea to fighting organisms.
