Abnormal Development - Toxoplasmosis
Introduction
The causal agent of Toxoplasmosis is the protist Toxoplasma gondii. This unicellular eukaryote is a member of the phylum Apicomplexa which includes other parasites responsible for a variety of diseases (malaria, cryptosporidiosis). The diagnosis and timing of an infection are diagnostically based on serological tests.
Recent findings suggest that pre-pregnancy immunization against toxoplasmosis may not protect against reinfection by atypical strains.
Some Recent Findings
Emerg Infect Dis. 2011 Jul;17(7):1327-8. Pomares C, Ajzenberg D, Bornard L, Bernardin G, Hasseine L, Darde ML, Marty P. Source Universite de Nice-Sophia Antipolis-Inserm U895, Nice, France. Abstract To the Editor: Toxoplasma gondii parasites are obligate intracellular apicomplexans that can infect virtually all warm-blooded animals; felids are definitive hosts. The most common sources of human infection are ingestion of tissue cysts in undercooked meat or of food or water contaminated with oocysts shed by felids and transplacental transmission. Acquired toxoplasmosis in immunocompetent humans is frequently asymptomatic but is associated with cervical or occipital lymphadenopathy in approximately 10% of patients. Severe or fatal outcomes for immunocompetent patients have been attributed to the virulence of specific T. gondii genotypes (1). We describe 3 cases of toxoplasmosis caused by atypical strains probably acquired by from ingestion of raw horse meat imported from Canada and Brazil. PMID: 21762609
