Occurrence of CAE and CLA in Swedish Dairy Goats and Comparison of Serum and Milk as Sampling Material

Caprine arthritis encephalitis (CAE) and caseous lymphadenitis (CLA) are two infectious diseases affecting goat welfare production throughout the world. There no current data regarding their prevalence in Sweden, aim of this pilot study was therefore to estimate occurrence Swedish milk-producing goats, but also assess agreement between milk sera as sample material for diagnosis investigate association somatic cell count (SCC) bulk CAE CLA. Serum, individual milk, bulk-tank samples were collected from 214 dairy goats 10 herds. All analysed by ELISA detect antibodies CLA, 14.6% seropositive CAE, whereas 19.3% The serum over 90% both can be considered an alternative analysis a future eradication programme. Based on limited number samples, there significant correlation bulk-milk test results within-herd seroprevalence SCC measured using DeLaval counter. medium 639,000 cells/mL or CLA could found. indicate that common herds, further studies based larger herds needed draw conclusions about national prevalence. used more cost-effective sampling media diagnosing compared serology, which is standard procedure today. Hopefully, support establishment successful programme control diseases, with ambition eradicate Sweden.
