摘要: Sera from 1,700 beef and dairy cattle in Israel were tested for besnoitiosis by indirect immunofluorescence. Over 90% of animals negative whereas about 50% positive. Among bulls the percentage positive reactors increased with age but cows pattern was less clear; 36% young imported upon arrival developed antibody titres after one season on range. Cross-tests withToxoplasma gondii antiserum antigen indicated that results survey unlikely to have been influenced byToxoplasma antibodies.
