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.

Existence of two groups of Staphylococcus aureus strains isolated from bovine mastitis based on biofilm formation, intracellular survival, capsular profile and agr-typing
Bardiaua, M.; Caplinb, J; Detilleuxc, J.; Graberd, H.; Moronie, P.; Taminiaug, B.; Mainila, J.G.; Veterinary Microbiology, 2016.
The first perspective of this study would be to check for the presence of these genes in a larger collection of strains to assess of their specificity for each cluster. In addition, it would be beneficial to study these features (intracellular survival, biofilm formation, capsular typing and agr-typing) in S. aureus strains isolated from other hosts and other pathologies to specify if these clusters are specific to bovine mastitis S. aureus strains or are present in all S. aureus strains.
