Prediction of intramammary infection status across the dry period from lifetime cow records
Henderson, A. C.; Hudson, C. D., Bradley, A. J.; Sherwin, V. E.; Green, M. J. - Journal of Dairy Science, 2016, Vol. 99: 1-10.
The dry period is very important for mammary gland health, with the aim not only to cure existing intramammary infections (IMI) but also to prevent new IMI. Although it is known hat the dry period is an important time for optimizing udder health, the probability that individual cows will succumb to a new IMI or, if infected, will fail to cure an IMI is not well stablished. The aim of this study was to investigate whether lifetime cow data, available through routine on-farm milk recording, could be used to predict changes in IMI status across the dry period.

Prevalence of Bovine Mastitis Pathogens in Bulk Tank Milk in China
Bi, Y.; Wang, YJ.; Qin, Y.; Guix Vallverdú, R.; Maldonado García, J.; Sun, W., et al. (2016)
The objectives of this study were to estimate the herd prevalence ofmajor mastitis pathogens in bulk tank milk (BTM) in China dairy herds, to etermine the relationship between the presence of mastitis pathogens and bulk tank milk somatic cell counts (BTSCC), and to investigate the impact of different dairy cattle farming modes and region on bacterial species. BTM samples collected from 894 dairy herds in China were examined for the presence of mastitis pathogens.

Intramammary infection with coagulase-negative staphylococci at parturition: Species-specific prevalence, risk factors, and effect on udder health
De Visscher, A.; Piepers, S.; Haesebrouck, F.; De Vliegher, S. - Journal of Dairy Science, 2016, Vol. 99: 1-13.
Coagulase-negative staphylococci (CNS) are the main cause of bovine intramammary infections (IMI) in many countries. Despite a high prevalence of CNS IMI at parturition, species-specific risk factor studies, relying on accurate identification methods, are lacking. Therefore, this observational study aimed at determining the prevalence and distribution f different CNS species causing IMI in fresh heifers and dairy cows in Flemish dairy herds and identifying associated speciesand subgroup-specific risk factors at the herd, cow, and quarter level.

Prevalence of contagious and environmental mastitis-causing bacteria in bulk tank milk and its relationships with milking practices of dairy cattle herds in São Miguel Island (Azores)
Azevedo, C.; Pacheco, D.; Soares, L.; Romão, R.; Moitoso, M.; Maldonado, J.; Guix, R.; Simões, J.; Trop Anim Health Prod., 2016.
This study aimed to assess the degree of contamination of bulk tank milk (BTM) by Staphylococcus spp. and coliform bacteria and to identify major milking practices that help perpetuate them in dairy cattle herds in São Miguel Island .
