Detecção de Toxoplasma gondii em órgãos do sistema reprodutivo de carneiros naturalmente infectados no Brasil

Abstract

The aim of the study was to detect genomic DNA of Toxoplasma gondii in testicle and epididymis samples from rams sold in abattoirs in the state of Pernambuco, Northeast Brazil. Fifty (50) blood serum samples were collected, as well as 50 testicle and epididymis samples. Indirect Immunofluorescence (IIF) was used during screening of the rams. The Polymerase Chain Reaction (PCR) was used with animals that were positive in serology. Our results confirmed that 24% (12/50) of the rams were positive in IIF. Genomic DNA was detected in the epididymis at 8.3% (1/12) of the animals. The molecular identity of the amplified products was confirmed through sequencing. This paper reports the first occurrence of T. gondii DNA in the reproductive organs of naturally infected rams in Brazil.
