Jaundice in mice due to anomalies of the biliary tract.

There has been described a previously unrecognized disease of mice, characterized by progressive jaundice, first appearing during the nursing period. This has been shown to be due to congenital absence of the terminal segment of the common bile duct, or to the absence of intrahepatic ducts. In the former case, there is distension of the cystic and hepatic ducts, and of the gall bladder, with mucoid material. Biliary cirrhosis and infarct-like areas of necrosis are commonly found in the liver. The cause of the necroses has not been positively determined, but it is suggested that they result from defective arteriolization of the hepatic parenchyma. Inflammatory lesions of the biliary passages, when present, are attributed to secondary bacterial infection. Protozoan-like parasites were present in the gastric epithelium of all mice examined. Their relationship to the biliary and hepatic lesions is as yet undetermined.

An apparently new lethal virus disease of infant mice.

A hitherto unreported disease of infant mice is described. The agent reproduces upon passage, is filterable, is confined mainly to the gastrointestinal tract in infant and adult mice, causes death in infants and inapparent infection in adults, and is sensitive to mild heat, ether, and sodium deoxycholate. Unique and characteristic morphologic changes occur in the epithelial cells of the intestine in infected infant mice. These consist in the development of multinucleated giant cells designated "balloon cells.".
