Innate immune response to intramammary infection with Serratia marcescens and Streptococcus uberis
, 2004 Streptococcus uberis and Serratia marcescens are Gram-positive and Gram-negative bacteria, respectively, that induce clinical mastitis. Once initial host barrier systems have been breached by these pathogens, the innate immune system provides the next ...

Intramammary Infections in Primigravid Heifers Near Parturition
Journal of Dairy Science, 1983 Mammary secretion from 32 primigravid heifers was obtained aseptically to determine frequency of bacterial isolation and incidence of intramammary infection near parturition. Quarter samples were collected 14 and 7 days prior to expected parturition, at parturition, and 7 and 14 days postparturition.

Approaches to modeling intramammary infections in dairy cattle
Preventive Veterinary Medicine, 1999 In this paper, three approaches (Markov processes, discrete-event simulation, and differential equations) to modeling intramammary infections (IMI; focusing on the dynamic changes between uninfected, subclinical, and clinical udder health states) are described.
