This study determined optimal parameters for producing controlled-release microspheres and examined their suitability for vaccines via ingestion by bovine leukocytes. Microspheres elicit an immune response when ingested by antigen-presenting cells an

A large portion of new IMI in dairy cattle occurs during the nonlactating period. Because antibiotic infusions at the beginning of the nonlactating period are only partially effective, attempts have been made to stimulate the production of protective

Cultures of teat, ductal and secretory epithelial cells were used to study the role of alpha-toxin and the capsular exopolysaccharide on the adherence of Staphylococcus aureus to mammary epithelium. The adherence of S aureus to the cells and their su

Exopolysaccharide capsule is a major virulence factor of Staphylococcus aureus because it inhibits neutrophil recognition of antibodies to highly antigenic S. aureus cell wall. To circumvent this inhibition, two modes of immunization were tested for

The ability of specific bovine Ig isotypes to enhance phagocytosis of Staphylococcus aureus by polymorphonuclear neutrophils was studied. Polymorphonuclear neutrophils were isolated from the blood of 14 lactating Holstein cows. Antibodies against S.

One of the major virulence factors of Staphylococcus aureus is development of an exopolysaccharide capsule in vivo, which inhibits recognition of antibodies to highly antigenic cell wall by neutrophils. To circumvent this inhibition, an attempt was m

Staphylococcus aureus is responsible for a major portion of the economic losses due to mastitis. Attempts to produce a vaccine to prevent S. aureus mastitis have been hampered by the low immunogenicity of the polysaccharide, which forms on the surfac

Neutrophils are the major defense against bacterial infection in the bovine mammary gland. Neutrophils migrate from blood into the lumen of the gland in response to inflammatory stimuli. This study describes the development of a system of cell cultur

Bovine mammary secretory cells, isolated at necropsy, were cultured in vitro and used as a model to study the mode of adherence of Staphylococcus aureus to mammary epithelium. Cultured cells were characterized by their morphology and physiology as se
