چکیده

In a cohort of 12 consecutive neonates, polymerase chain reaction (PCR) established the diagnosis of 5 of 6 cases of congenital toxoplasmosis and did so earlier than serologic methods. We validated that PCR using neonatal peripheral blood is a sensitive, rapid, and cost-effective method to affirm the diagnosis of previously undiagnosed congenital toxoplasmosis.

Performance of Polymerase Chain Reaction Analysis of the Amniotic Fluid of Pregnant Women for Diagnosis of Congenital Toxoplasmosis: A Systematic Review and Meta-Analysis.

INTRODUCTION Congenital infection caused by Toxoplasma gondii can cause serious damage that can be diagnosed in utero or at birth, although most infants are asymptomatic at birth. Prenatal diagnosis of congenital toxoplasmosis considerably improves the prognosis and outcome for infected infants. For this reason, an assay for the quick, sensitive, and safe diagnosis of fetal toxoplasmosis is des...

Development of an efficient multiplex semi-nested PCR for convenient use in urine samples for diagnosis of toxoplasmosis

BACKGROUND: Toxoplasmosis is a protozoan parasitic infection. The cerebrospinal, ocular and congenital forms of the disease are complicated and life threatening. Diagnosis of toxoplasmosis is difficult due to invasive sample requirement, complications in pathogenesis, immunology, and interpretation of test results. Using urine as a non invasive sample source for molecular diagnosis of toxoplasm...

Diagnosis of Toxoplasma gondii infections in newborn farm foxes by polymerase chain reaction (PCR)

The purpose of the study was to confirm congenital toxoplasmosis in dead newborn foxes derived from seropositive vixens. The polymerase chain reaction (PCR) technique was used to identify T. gondii DNA in 24 samples from neonate organs (lung, liver, brain). B 1 gene sequence was amplified using two pairs of primers. Lung, liver and brain samples from 4 newborn foxes (in all 9 samples) gave posi...

Congenital toxoplasmosis: evaluation of molecular and serological methods for achieving economic and early diagnosis among Egyptian preterm infants.

BACKGROUND Early diagnosis of congenital toxoplasmosis (CT) is difficult when specific immunoglobulin M (IgM) antibodies are absent, or if persist for months, in the newborn infant's blood. OBJECTIVES To study the risk factors of neonatal toxoplasmosis and to compare different immunologic profiles (Toxoplasma-specific IgM, IgA antibodies and the avidity of IgG antibodies) with polymerase chai...

Use of the polymerase chain reaction in the diagnosis of acquired ocular toxoplasmosis in an immunocompetent adult.

Gene amplification by the polymerase chain reaction (PCR) is useful in ophthalmic diagnosis since it enables exceedingly small amounts of nucleic acid to be detected in ocular samples. Studies have indicated a potential for the use of PCR on ocular specimens to assist the clinical diagnosis of ocular toxoplasmosis.' We describe a case in which the technique was used in the diagnosis of acquired...
