[Test of the effectiveness of tylan on spirochetosis in chickens].
The water-soluble preparation Tylan in conc. 1:2000 in the drinking water for three consecutive days was used successfully against spirochetosis in birds both experimently and in the field practice, as a therapeutic and prophylactic means. 175 (92 per cent) out of 190 affected birds in a spontaneous breakout of spirochetosis recovered. It was found experimentally that Tylan does not interfere with immunogenesis. This made it possible for the authors to vaccinate 10,000 chickens from flocks with manifested spirochetosis along with giving Tylan as a therapeutic and prophylactic agent. Spirochetosis ceased and was no more observed up to the time of slaughter i. e., six months following vaccination. If there are no ticks on the spirochetosis-affected farms it is possible to bring to an end the disease through the therapeutic and prophylactic use of Tylan together with disinfection with 1 per cent sodium hydroxide, no vaccination being needed.
