Elevated Toxoplasma gondii Infection Rates for Retinas from Eye Banks, Southern Brazil

Emerg Infect Dis. 2016 Apr;22(4):691-3. doi: 10.3201/eid2204.141819.

Abstract

We found significantly higher incidence of Toxoplasma gondii DNA in eye bank specimens from Joinville in southern Brazil (13/15, 87%) than in São Paulo (3/42, 7%; p = 2.1 × 10E-8). PCR DNA sequence analysis was more sensitive at locus NTS2 than at locus B1; a high frequency of mixed co-infections was detected.

Keywords: Toxoplasma gondii; genotype; ocular toxoplasmosis; parasites; retina; serotype.
