Another group of ewes was not immunized. All ewes had previously grazed pasture lightly infected with <jats:italic>T. ovis eggs<\/jats:italic>. Most lambs from non-immunized ewes developed cysts after oral infection with <jats:italic>T. ovis eggs<\/jats:italic>. However, no lambs from immunized ewes developed cysts up to and including 6 weeks after birth. Between 8 and 16 weeks after birth a proportion of lambs were found to be susceptible to infection. By 18 weeks after birth all lambs were apparently susceptible. The 99% confidence band for the mean duration of demonstrable complement-fixing antibody titres was 6\u00b72\u20137\u00b78 weeks for lambs from immunized ewes. The persistence of maternal protective antibody in some lambs could possibly preclude successful active immunization of all lambs against <jats:italic>T. ovis<\/jats:italic> larvae before 18 weeks of age.<\/jats:p>","DOI":"10.1017\/s0031182000053269","type":"journal-article","created":{"date-parts":[[2009,6,5]],"date-time":"2009-06-05T12:50:34Z","timestamp":1244206234000},"page":"177-182","source":"Crossref","is-referenced-by-count":18,"title":["The duration of passive protection against <i>Taenia ovis<\/i> larvae in lambs"],"prefix":"10.1017","volume":"79","author":[{"given":"D.
