Magazine on Mastitis and Milk quality for the dairy professional
Bovine mastitis, an inflammation of the udder, is among the most costly and persistent diseases in the dairy industry. It compromises cow welfare, reduces milk yield and quality, and drives high antibiotic use. Two important bacterial culprits are Staphylococcus aureus and Streptococcus dysgalactiae. Despite decades of research, these pathogens remainRead more
Read MoreMastitis caused by Staphylococcus aureus and non-aureus staphylococci and mammaliicocci (NASM) represents an increasing threat to the milk production chain, driven by the extensive use of antimicrobials and resulting economic losses in dairy herds. The aim of the thesis was to investigate the prevalence of S. aureus and NASM subclinicalRead more
Read MoreMycoplasma bovis infections affect dairy cattle worldwide, yet few countries have implemented surveillance, control, or monitoring programs. Critical gaps remain in our understanding of the disease dynamics, transmission, and epidemiology. Additionally, diagnosing M. bovis is challenging due to suboptimal diagnostic tests, subclinical infections and intermittent shedding, making it difficult to identify infected animals. To address these challenges, a series of studies have aimed to improve both diagnostic protocols and understanding of transmission dynamics.
Read MoreBovine mastitis is the lead cause of economic loss disease in the dairy industry, responsible for and accounts for up to 70% of antimicrobial use on dairy farms. In light of rising concerns about antimicrobial resistance, immunological strategies are being explored to optimize dairy cows’ immune responses and reduce relianceRead more
Read MorePrevious studies have suggested that udder health may be impaired on organic dairy farms. However, there is limited knowledge about udder health in dairy cows on organic farms, with prior research primarily addressing herd-level management. This leaves gaps in understanding individual cow-level mastitis pathogen prevalence and dynamics. Given the potentialRead more
