A clinical case of enzootic bovine leukosis in a Holstein cow with minor clonality of B-cell in the peripheral blood.

A 4-year 9-month-old Holstein-Friesian dairy cow presented with anorexia. On physical examination, swelling of superficial lymph nodes, pelvic masses, and prolonged urination posture after urinating a small amount were noted. Hematological examination revealed no lymphocytosis.

Lipopolysaccharide-binding protein in follicular fluid is associated with the follicular inflammatory status and granulosa cell steroidogenesis in dairy cows.

Metabolic stress and subsequent hepatic dysfunction in high-producing dairy cows are associated with inflammatory diseases and declining fertility. Lipopolysaccharide (LPS)-binding protein (LBP) is produced by hepatocytes and controls the immune response, suggesting that it is involved in the pathophysiology of inflammation-related attenuation of reproductive functions during metabolic stress. This study investigated the effect of LBP on the inflammatory status, oocyte quality, and steroidogenesis in the follicular microenvironment of dairy cows.
