Summary of "Identification of candidate antigens by 2-DE Immunoblotting for diagnosis of Toxoplasma gondii infection in chickens and rabbits."

Toxoplasmosis, caused by apicomplexan parasite Toxoplasma gondii, is a common food-borne disease in humans. Undercooked meat is a potential source of T. gondii infection. As meat of chicken or rabbit is consumed worldwide, tools such as ELISA for the detection of infection of this parasite in rabbits and chickens are much-needed. To search diagnostic antigens of T. gondii special for rabbits and chickens, we conducted two dimensional electrophoresis (2-DE), Western blotting and mass spectrometry (MS) with T. gondii tachyzoite proteins. When probed with rabbit or chicken anti-T. gondii sera, about 60 positive spots among over 500 visible protein spots were detected. In subsequent mass spectrometric analysis, microneme 4 (MIC4) and a putative rhoptry protein are of diagnositic value among the 13 spots selectively picked from the equivalent gel. This study encourages further validation of these candidate antigens for the development of immunologic tools for the detection of T. gondii infection in chickens and rabbits.

Medical and Biotech [MESH] Definitions

The acquired form of infection by Toxoplasma gondii in animals and man.

Prenatal protozoal infection with TOXOPLASMA gondii which is associated with injury to the developing fetal nervous system. The severity of this condition is related to the stage of pregnancy during which the infection occurs; first trimester infections are associated with a greater degree of neurologic dysfunction. Clinical features include HYDROCEPHALUS; MICROCEPHALY; deafness; cerebral calcifications; SEIZURES; and psychomotor retardation. Signs of a systemic infection may also be present at birth, including fever, rash, and hepatosplenomegaly. (From Adams et al., Principles of Neurology, 6th ed, p735)

A genus of protozoa parasitic to birds and mammals. T. gondii is one of the most common infectious pathogenic animal parasites of man.

A macrolide antibiotic produced by Streptomyces ambofaciens. The drug is effective against gram-positive aerobic pathogens, N. gonorrhoeae, and staphylococci. It is used to treat infections caused by bacteria and Toxoplasma gondii.

Infections of the BRAIN caused by the protozoan TOXOPLASMA gondii that primarily arise in individuals with IMMUNOLOGIC DEFICIENCY SYNDROMES (see also AIDS-RELATED OPPORTUNISTIC INFECTIONS). The infection may involve the brain diffusely or form discrete abscesses. Clinical manifestations include SEIZURES, altered mentation, headache, focal neurologic deficits, and INTRACRANIAL HYPERTENSION. (From Joynt, Clinical Neurology, 1998, Ch27, pp41-3)
