| Abstract: | A new and simple technique for isolation of C. ruminantium in bovine and ovine vascular endothelial cells (aorta, pulmonary artery) is described. Unlike previous studies, no efforts were made to retard cell growth by irradiation or chemicals. Instead, heparin-derived plasma samples obtained from only those animals exhibiting prolonged or extremely high temperatures were used. In this way, C. ruminantium was isolated from 27 of 37 samples (73%) and from 22 of 26 animals (85%). A total of six Zimbabwean stocks of C. ruminantium were isolated in cell culture. |
