..aureus IMI, but Lysigin showed benefit in reducing the clinical severity and duration of clinical disease post-challenge. Neither of the experimental bacterins appeared to perform better than Lysigin...

..The reductions in trace mineral concentrations were of less magnitude than observed following experimental E. coli mastitis...

..aureus (P< or = 0.030). Hence, a humoural immune response to the vaccine was detected in serum and milk, but responses varied according to strain and antibody isotype tested...

..222). Methicillin-resistant S. aureus isolates in this study seemed to be community acquired rather than hospital acquired...

..aureus vaccines developed have adequately prevented new infection. The antigens targeted by S. aureus vaccines and potential reasons for the lack of success of vaccination against S. aureus are reviewed in this article...

..Overall, no significant differences were found between strains, suggesting that the degree of udder parenchymal injury induced by S. aureus IMI is in general significantly affected by factors other than strain type...

..02). Herds that purchased replacement heifers had more total strains of Staphylococcus aureus (P = 0.01) and more new strains (P = 0.04) enter the herd than closed herds...

..No difference in total milk production between lactation one and two in either group was found, suggesting that permanent loss of a quarter was not detrimental to overall milk production...

..A higher prevalence of methicillin-resistant Staphylococcus aureus (MRSA) colonization is reported in healthcare workers compared with nonhealthcare workers...

..The zinc sulfate turbidity test was inadequately specific (0.33) and resulted in misclassification of 33% of calves...

..Mechanisms of TSE transmission vary among host species. The diagnostic approach for TSEs of ruminants is presented,and the history and justification of regulatory programs to control and eradicate TSEs are outlined...

..CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that prepartum treatment of dairy heifers with pirlimycin may reduce the prevalence of early lactation IMI, particularly IMI caused by CNS, without causing pirlimycin residues in milk...

..An ameloblastoma was diagnosed histologically and palliative radiation therapy was attempted. Because of poor response to therapy and anorexia the animal was euthanized. Necropsy findings confirmed an ameloblastoma of acanthomatous type...

..This is the first report of a baculovirus-expressed recombinant S. neurona antigen being used to detect anti-S. neurona antibodies in a variety of host species...

..CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that neither CMT score nor SCC is sensitive enough to be useful as a screening test for identifying infected mammary quarters among dairy cattle in a herd with high bulk tank SCC...
