Notes |
Immunocompetent persons with primary infection are usually asymptomatic, but latent infection can persist for the life of the host. In the patient with IgM antibodies alone with subsequent seroconversion, a diagnosis of toxoplasmic lymphadenitis can be made; in the patient without any evidence of either IgM or IgG antibodies, the diagnosis is eliminated. Additional testing may be pursued at a reference laboratory for confirmation of equivocal assay results subject to approval by the consultant microbiologist, Dr. Brendan Crowley. Toxoplasma encephalitis is the most common presentation of toxoplasmosis as an opportunistic infection among AIDS patients and occurs most commonly in those with a CD4 count <100 cells/microL. Prophylaxis against PCP and the widespread use of HAART in developed countries has greatly decreased the incidence of this infection. Specimens sent to National Virus Reference Laboratory, University College Dublin, Belfield, Dublin 4 Send sample to the laboratory without delay. Sample should be refrigerated if not transported immediately. |
