- Unexpected oocyst shedding by cats fed Toxoplasma gondii tachyzoites . . .
Tachyzoites, bradyzoites (in tissue cysts), and sporozoites (in oocysts) are the three infectious stages of Toxoplasma gondii The prepatent period (time to shedding of oocysts after primary infection) varies with the stage of T gondii ingested by the cat The prepatent period (pp) after ingesting bradyzoites is short (3–10 days) while it is long (18 days or longer) after ingesting oocysts
- THE DEVELOPMENT AND BIOLOGY OF BRADYZOITES OF
The prepatent period (time to oocyst sheeding) in cats following feeding of bradyzoites is shorter (3 to 7 days) than that following feeding of tachyzoites (over 14 days)
- Oocyst-Induced Toxoplasma gondii Infections in Cats - JSTOR
When either sporozoites or tachyzoites are ingested by cats, first tachyzoites and subse- quently bradyzoites are formed in succession, and the latter may disseminate to the intestinal mu- cosa after a variable interval, which is followed by the development of the enteroepithelial cycle and oocysts
- Toxoplasma Gondii - Medical Microbiology - NCBI Bookshelf
Cats acquire Toxoplasma by ingesting any of three infectious stages of the organism: the rapidly multiplying forms called tachyzoites (Fig 3), the quiescent bradyzoites that occupy cysts in infected tissue (Fig 4), and the oocysts shed in feces (Fig 5)
- Tachyzoite-induced life cycle of Toxoplasma gondii in cats
The tachyzoite-induced cycle of Toxoplasma gondii was studied in 46 cats Tachyzoites of the M-7741 or Me-49 strain of T gondii were administered orally to cats by pouring into the mouth or by stomach tube, or by intraintestinal inoculation Ten weaned cats that had been inoculated with tachyzoites …
- TOXOPLASMA GONDII INFECTION IN CATS - SAGE Journals
Domestic cats and other felids are the natural hosts – non-feline species serve only as intermediates 1,2 Three infectious structures be distinguished: sporozoites in oocysts, tachyzoites (the actively multiplying stage), and bradyzoites (the slowly multiplying stage) enclosed in tissue cysts

Any warm-blooded animals, including humans and cats, can serve as intermediate hosts How is Toxoplasma gondii transmitted? Transmission occurs via ingestion of sporulated oocysts, tissue cysts (bradyzoites) in undercooked meat, or tachyzoites Congenital transmission also occurs through dissemination of tachyzoites
- Gastro-intestinal Parasites of Cats - IVIS
The reason for the extended prepatent period is that the tachyzoites or sporozoites must first produce tissue cysts that contain bradyzoites Then, these bradyzoites will find their way back to the intestine to produce the enteroepithelial cycle that results in oocyst production
- Structures of Toxoplasma gondii Tachyzoites, Bradyzoites, and . . .
Abstract Infections by the protozoan parasite Toxoplasma gondii are widely prevalent worldwide in animals and humans This paper reviews the life cycle; the structure of tachyzoites, bradyzoites, oocysts, sporocysts, sporozoites and enteroepithelial stages of T gondii; and the mode of penetration of T gondii The review provides a detailed account of the biology of tissue cysts and
