Decrease in Erythrocyte Survival in Theileria sergenti-Infected Calves Determined by Non-Radioactive Chromium Labelling Method.

NOTE Clinical Pathology Cytokine and Inducible Nitric Oxide Synthase Gene Expressions in Peripheral Blood Mononuclear Cells and Related Clinical Characteristics in Theileria orientalis sergenti-Infected Calves

Eight splenectomized calves were inoculated with Theileria orientalis sergenti (Tos)-infected tick gland homogenate (5 calves) or infected erythrocyte suspension (3 calves). Clinical characteristics were different in calves post-infection. Animals were divided into 3 groups on the basis of susceptibility as high, middle, and low. Increase in mRNA of IFNγ, IL-2, and TNF-α was observed in periphe...

Unusual cases of Theileria annulata infection in calves

The nature of anaemia in rheumatoid arthritis. V. Red Cell survival measured by radioactive chromium.

A number of studies have been undertaken to assess the importance of shortened red cell survival in the causation of anaemia complicating rheumatoid arthritis. Freireich, Ross, Bayles, Emerson, and Finch (1954), using the Ashby technique, found reduction of the life span of transfused erythrocytes from normal individuals in patients suffering from the disease. Alexander, Richmond, Roy, and Duth...

A method for analysis of cell to cell transmission of Theileria sergenti piroplasms.

We tried to develop an experimental system for quantifying piroplasm transmission in Theileria sergenti infection using a SCID mouse model, of which red blood cells (RBC) had been substituted with bovine (Bo). A mouse hybridoma cell producing antibody against Holstein RBC was established for distinguishing Holstein RBC from Japanese Black RBC by a immuno-staining method. T. sergenti piroplasms ...

Prevalence of Theileria sergenti infection in Korean native cattle by polymerase chain reaction.

This study was performed to investigate the prevalence of theileriosis and to compare the prevalence of this disease in Korean native cattle reared under different environmental conditions, namely, in a grazing area and a non-grazing area by polymerase chain reaction. Three hundred and one Korean native cattle (276 cows and 25 bulls) that had not received prior treatment or been vaccinated to p...
