Dear Editors, – Jitender Dubey proved 18 years ago that cats reinfetcted with T gondii 6 years after initial infection re-shed oocysts.1 And yet, we still see statements like the following which was recently published in a consensus guidelines article by the ABCD in JFMS:2 ‘Thus, cats that have antibodies to T gondii no longer shed oocysts, and do not pose a risk to humans.’
How long will this myth continue to be perpetuated?
