The life cycle of the coccidian parasite, Toxoplasma gondii, in the domestic cat

Antibodies to Neospora caninum and Toxoplasma gondii in domestic cats from Brazil

“…We may consider these findings due to the feeding habits of the cats and the known epidemiological role of the rodents and birds in the biological cycles of T. gondii (Hutchison et al 1968(Hutchison et al , 1970(Hutchison et al , 1971Frenkel et al 1970, Frenkel 1973). In the case of N. caninum, Huang et al (2004) found 5.8% of rats to be seropositive to N. caninum, suggesting that these rodents can be reservoirs for this protozoan.…”

Toxoplasmosis

“…Although it has been recommended that pet cats should be banished for the duration of pregnancy [896,897], this measure is hardly feasible and not necessary under most circumstances. Repeated requests for serologic testing of cats are being received by veterinarians in the United States, and in many instances, serologic test results are misinterpreted in respect to the danger of transmission.…”

The coccidian parasites (Protozoa, Apicomplexa) of carnivores

“…gondii does not cross-react serologically with other coccidia (see Aryeetey and Piekarski, 1976 Levaditi et al (1929) and has since been cultivated by many persons (see Doran, 1973 Jacobs (1970), Frenkel (1970, Kozar (1970), Hutchison et al (1971, , Jones (1973), Levine (1973Levine ( , 1977b, Siim (1974), Senaud and Mehlhorn (1975), and Beverley (1976), among others. That T. gondii is a coccidium having an oocyst in cats like that of Isospora was discovered independently by Overdulve (1970) in the Netherlands, Work and Hutchison (1969, 1969a), and Hutchison et al (1970 in Scotland and Denmark, Weiland and Kuhn (1970) in Germany, Sheffield and Melton (1970) in Maryland, Frenkel, Dubey, and Miller (1970) in Kansas, and G.
