WebToxoplasma gondii is an apicomplexan protozoan that infects humans and other warm-blooded animals worldwide, including birds and marine mammals. This intracellular parasite has a facultative, indirect life cycle, reproducing sexually in enterocytes from definitive hosts and asexually in nucleated cells from intermediate hosts. WebThe dye test uses live, virulent Toxoplasma tachyzoites, a complement-like ‘accessory-factor’ and test serum. When specific antibody acts on the tachyzoites, the latter do not stain uniformly with alkaline methylene blue. The test has proven unreliable in some species.

Webtachyzoites. Tachyzoites can disseminate to extraintestinal tissues within a few hours of infection, via the lymph and blood. They can enter nearly any cell and multiply; the host cell eventually ruptures and the released tachyzoites enter new cells.

The lifecycle of T. gondii may be broadly summarized into two components: a sexual component that occurs only within cats (felids, wild or domestic), and an asexual component that can occur within virtually all warm-blooded animals, including humans, cats, and birds. Because T. gondii can sexually reproduce only within cats, cats are therefore the definitive host of T. gondii. All other hos…
