Immunopathological Study Of Foot And Mouth Disease In Calves

Six calves were experimentally infected by FI.llv type 1/2/1972 intradermolingual and one calf used as control.The infected animals were classified into three groups:The viraemic group, the peak of immunity and the re-infected group.The imQunological status was examined. The regional immunity waS represented by pharyngeal and submaxillary lymph nodes. The general central iw~unity was represented by the visceral lymph nodes (renal, hepatio, abomasal,mesentric; splenic) and the carcasS lymph nodes(prescapular, popliteal; iliac) together with the spleen. To study the virus effect sampling from the target sites (tongue, skin and heart) were taken. The other parenchymatous organs were examined for the si
