Changes in Antimicrobial Component Concentrations in Goat Milk Following Intramammary Lipopolysaccharide Administration. [PDF]

Anim Sci J
ABSTRACT Mastitis is a major cause of economic losses in dairy production; however, its prevention and treatment remain challenging. Under field conditions, antimicrobial drugs are frequently administered when somatic cell counts (SCCs) are elevated and signs of inflammation are observed, even in the absence of detectable pathogens in milk.

A multispecies model for the transmission and control of mastitis in dairy cows [PDF]

, 2001
Mastitis in dairy cows is a significant economic and animal welfare issue in the dairy industry. The bacterial pathogens responsible for infection of the mammary gland may be split into two main categories: major and minor pathogens. Infection with major

Transmission dynamics of intramammary infections caused by Corynebacterium species [PDF]

Journal of Dairy Science, 2018
The development of reliable models for transmission of intramammary infections (IMI) is the subject of extensive research. Such models are useful to enhance the identification and understanding of factors that affect pathogen-specific IMI dynamics. Longitudinal transmission models are valuable for predicting infection outbreak risks, quantifying the ...
