TLDR
The number and type of primary pathogen infections during early lactation were similar to those at parturition, and the number of coagulase negative staphylococcal infections decreased markedly.About:

Invited review: Mastitis in dairy heifers: Nature of the disease, potential impact, prevention, and control
S. De Vliegher,Lawrence K. Fox,Sofie Piepers,Scott McDougall,Herman W. Barkema,Herman W. Barkema +5 more
TL;DR: In conclusion, heifer mastitis can affect the profitability of dairy farming because of a potential long-term negative effect on udder health and milk production and an associated culling risk, specifically when major pathogens are involved.

Coagulase-negative staphylococci as cause of bovine mastitis- not so different from Staphylococcus aureus?
Suvi Taponen,Satu Pyörälä +1 more
TL;DR: Staphylococci are the bacteria most commonly isolated from bovine mastitis, and CNS are now predominant over S. aureus in most countries, and resistance to various antimicrobials is more common in CNS than in S.Aureus, but CNS mastitis responds much better to antimicrobial treatment than S.aureus mastitis.

Ecology of Staphylococcus aureus isolated from various sites on dairy farms
TL;DR: In herds with high (> 10%) or low (< 3%) prevalence of S. aureus IMI, S.aureus was isolated from heifer teat skin, heifer external orifices, housing, feedstuffs, humans, nonbovine animals, air, and equipment.

Udder health in the periparturient period.
TL;DR: Methods of controlling bovine mastitis during the periparturient period is an important area that requires additional research that needs to be developed that are effective against a variety of bacteria, including environmental mastitis pathogens, if additional control is to be achieved.

Invited review: Effect of udder health management practices on herd somatic cell count
TL;DR: A systematic review of the scientific literature on relationships between management practices used on dairy farms and herd somatic cell count (SCC) generates a more comprehensive understanding of the management practices influencing SCC and highlights areas of SCC control knowledge that lack evidence of effectiveness.

408. Udder infections in the ‘dry period’. I
TL;DR: In a herd averaging forty-five to fifty cows in milk, large numbers of infections occurred during the dry period and over half of these developed during the first 3 weeks after the final milking-out of the udder.

TL;DR: There was an indication that the longer a quarter was free from infection the greater were its chances of remaining so, and no major seasonal trends were found in the incidence of udder infection and mastitis, although the incidence was slightly higher in the summer months.

TL;DR: Treatment reduced infection during early involution but failed to prevent new infection during the remainder of the dry period, and isolation of primary pathogens was reduced 50% in right infused quarters during the 1st wk of involution as compared to left uninfused quarters.
