Naturally Occurring Poliomyelitis Antibody in Hamilton, Montana

Naturally occurring ehrlichiosis in Egyptian dogs

Canine ehrlichiosis has emerged as one of the most clinically important tick-borne diseases affecting dogs. Eighty-five naturally infected dogs have been investigated, the most consistent clinical signs recorded were fever, emaciation and lymphoadenopathy, anemia, monocytosis, thrompocytopenia, hypoalbuminemia, elevation in liver enzymes and total bilirubin were the most remarkable changes asso...

Anti-C as a naturally-occurring antibody.

IT IS accepted generally that antibodies directed against red blood cell antigens in the Rh system result from isoimmunization either by transfusion or pregnancy and rarely can be considered “naturally-occurring.” Diamond et al. reported the first example of a naturally-occurring antibody within this system in 1942.3 They described an antibody, apparently anti-D, in the serum of a five-year-old...

Naturally Occurring Human Antibody Reacting with Bence Jones Proteins

Agglutinating substances having characteristics of naturally occurring macroglobulin antibodies to human Bence Jones proteins have been identified in human sera. By means of hemagglutination and hemagglutination inhibition techniques, common determinants have been demonstrated on the light (L) polypeptide chains of pooled normal human gamma(2)-globulin and on some Bence Jones proteins of group ...

Naturally occurring fluorescence in frogs.

Fluorescence, the absorption of short-wavelength electromagnetic radiation reemitted at longer wavelengths, has been suggested to play several biological roles in metazoans. This phenomenon is uncommon in tetrapods, being restricted mostly to parrots and marine turtles. We report fluorescence in amphibians, in the tree frog Hypsiboas punctatus, showing that fluorescence in living frogs is produ...
