A missense variant in DGKG as a recessive functional variant for hepatic fibrinogen storage disease in Wagyu cattle.

Hepatic fibrinogen storage disease (HFSD) was diagnosed in a 5-month-old Wagyu calf with a history of recurrent respiratory disease. It was characterized by lethargy, dehydration, acidemia, and increased liver enzyme activities. Histologically, disseminated hepatocytes were swollen and showed a single, sharply demarcated, faintly eosinophilic cytoplasmic inclusion with a ground-glass appearance, with the nucleus in an eccentric position.

Human Anti-Lipopolysaccharid (LPS) antibodies against Legionella with high species specificity.

Legionella are Gram-negative bacteria that are ubiquitously present in natural and man-made water reservoirs. When humans inhale aerosolized water contaminated with Legionella, alveolar macrophages can be infected, which may lead to a life-threatening pneumonia called Legionnaires' disease. Due to the universal distribution of Legionella in water and their potential threat to human health, the Legionella concentration in water for human use must be strictly monitored, which is difficult since the standard detection still relies on lengthy cultivation and analysis of bacterial morphology.
