摘要

Acute E. coli mastitis is associated with rapid onset of clinical signs including mammary gland swelling and abnormal milk with rapid elimination of bacteria from milk. In some cases, severe systemic involvement occurs and when not properly diagnosedand treated, could result in death of the animal. Reports have also described strains of E. coli showing very different clinical trends (Dogan et al., 2006; Dopfer et al., 1999; 2000). Some strains of E. coli gain access to the mammary gland and are associated with chronic IMI. Chronic E. coli Dvfl usually start with mild clinical symptoms that disappear soon after the onset of infection only to flare-up again during lactation, usually resulting in mild clinical mastitis. Escherichia coli associated with chronic mastitis have been isolated in milk for very long periods in spite of a high number of somatic cells in milk. Recently published data suggests that adhesion to and internalization into mammary epithelial cells and subsequent intracellular survival are important virulence attributes of strains of E, coli associated with chronic mastitis (Dogan et al., 2006; Dopfer et al., 2000).
