	abstract = {Composite 24 h milk samples were collected for detailed milk analysis  from each quarter of ten cows known to be free of intramammary infection.  Milk yield and concentration of lactose and serum albumin (BSA) were  significantly higher (P<0.001), and chloride ions significantly lower  (P<0.001), in hind compared with fore quarters. Four cows developed  clinical intramammary infection when subsequently challenged in the left  hind quarter with Streptococcus uberis. For all parameters measured, i.e.  protein, lactose, somatic cell count (SCC), BSA and immunoglobulins  (IgG), milk from the infected quarter differed significantly from the  uninfected quarters. No effect of infection was observed in quarters adjacent  to the infected quarter, except for SCC, which increased significantly  (P<0.001) in the uninfected hind quarter. Milk proteolytic activity in the  infected quarter increased significantly (P<0.001) due to increased  conversion of plasmin to plasminogen.},
