These data suggest that the cell tropism of lentiviruses may extend beyond the narrow boundaries of lymphocytes and macrophages. Viral RNA was identified in macrophagelike cells in lung, liver, spleen, and lymph nodes, in cells lining the vessels of brain and synovium, and in epithelial cells of intestinal crypts, renal tubules, and thyroid follicles. Fewer cells with viral transcripts were seen in noninflamed tissues. These cells were morphologically compatible with macrophages. Large numbers of cells with viral transcripts were detected in inflamed brain, spinal cord, lung, joints, and mammary gland. Further investigations need to be done to explore the seroconversion of CAEV in small ruminants and the associated factors to plan an appropriate eradication program and prevent transmission.Pathologic specimens of 18 goats with classical lesions of caprine arthritis-encephalitis (CAE) virus infection were examined morphologically and by in situ hybridization using molecularly cloned CAEV deoxyribonucleic acid (DNA) to determine which tissues and cells of naturally infected goats supported virus replication. This disease poses serious animal health problems that constrain production with the presence of apparent clinical signs. There has been a significant difference (p 0.05) of goats.Ĭonclusion: This finding indicates that CAEV infection exists in the goat flocks in examined localities in Ethiopia. ![]() The overall seroprevalence of CAE was 4.7%. Of the total samples tested from clinical cases, 7 (58.3%) were sero-positive for the presence of antibodies against CAEV. Chronic pneumonia was the highest cause of goat morbidity (50.8%) and mortality (100.0%). Results: During five consecutive years of longitudinal clinical study, a total of 195 clinical diseases of chronic pneumonia, nerve problems, clinical mastitis, and arthritis occurred with prevalence of 99 (50.8%), 57 (29.2%), 27 (13.9%), and 12 (6.2%), respectively. Records have been statistically analyzed by using the chi-square test. A total of 257 serum samples have been collected from apparently health and clinical cases attributed to CAE infection and tested with the usage of indirect enzyme-linked immunosorbent assays to screen antibodies against CAE. Methods: A cross-sectional serological study and a longitudinal clinical case study were conducted. The present study was conducted to determine the rate of morbidity and mortality due to clinical diseases attributed to infection by Caprine arthritis encephalitis virus (CAEV) and to determine the serological status of CAEV in goat in North Shewa, Ethiopia. ![]() It is mainly manifested as encephalitis in kids and polyarthritis in adult goats. Introduction: Caprine arthritis encephalitis (CAE) is a chronic debilitating and economically important viral disease of goats.
