Dividing T. gondii parasites. Toxoplasma gondii (/ ˈ t ɒ k s ə ˌ p l æ z m ə ˈ ɡ ɒ n d i. aɪ,-iː /) is a species of parasitic alveolate that causes toxoplasmosis. [3] Found worldwide, T. gondii is capable of infecting virtually all warm-blooded animals, [4]: 1 but felids are the only known definitive hosts in which the parasite may undergo sexual reproduction.
Toxoplasma gondii has been reported as the cause of death of a giant panda kept in a zoo in China, who died in 2014 of acute gastroenteritis and respiratory disease. [111] Although seemingly anecdotal , this report emphasizes that all warm-blooded species are likely to be infected by T. gondii , including endangered species such as the giant panda.

Toxoplasma gondii induces behavioural changes in rats by infecting central nervous system neurons. While some parasites exploit their hosts' typical immune responses, others seem to alter the immune response itself. For example, the typical immune response in rodents is characterized by heightened anxiety. [48]
Toxoplasmosis (Toxoplasma gondii) The name Apicomplexa derives from two Latin words—apex (top) and complexus (infolds)—for the set of organelles in the sporozoite. The Apicomplexa comprise the bulk of what used to be called the Sporozoa, a group of parasitic protozoans, in general without flagella, cilia, or pseudopods.
The taxonomy of this group is complex and only partly understood. Two major clades have been identified: the isosporoid coccidia (Toxoplasma, Neospora, Isospora [in part], and Sarcocystis) and a second clade containing Lankesterella, Caryospora and the eimeriid coccidia (Cyclospora, Isospora [in part] and Eimeria).
