Innate immunity of the bovine mammary gland.
Understanding the immune defenses of the mammary gland is instrumental in devising and developing measures to control mastitis, the major illness of dairy ruminants. Innate immunity is an extremely broad field for investigation, and despite decades of research, our present knowledge of the innate defenses of the udder is incomplete. Yet, information is being gained on the recognition of pathoge...
متن کاملLocal vaccination with killed Streptococcus uberis protects the bovine mammary gland against experimental intramammary challenge with the homologous strain.
The ability of killed streptococcus uberis to induce protection against mastitis when administered either into the cistern of the dry mammary gland (intramammary vaccination) without adjuvant or subcutaneously with adjuvant was investigated. Bacteria were never reisolated from vaccinated quarters following challenge with the same strain during the subsequent lactation, and no inflammatory respo...
متن کاملThe complement in milk and defense of the bovine mammary gland against infections.
The mammary gland of dairy cows, which is prone to infection by various bacteria, mobilizes local and systemic immune defenses to cope with pathogens. The complement system plays an important part in the innate immunity against microorganisms through its bactericidal, opsonic, and phlogistic functions. The amount of the complement in the milk of healthy glands of dairy cows is low. Moreover, th...
متن کاملMobilization of neutrophils and defense of the bovine mammary gland.
The leucocytes present in normal milk are not very efficient in preventing infection, because very small numbers of bacteria are able to induce infection experimentally. The mobilization of phagocytes from the blood to milk appears crucial in coping with the expansion of the bacterial population in the mammary gland. Important parameters for the outcome of mammary infections are the bactericida...
