Detection of Toxoplasma gondii DNA in Brazilian oysters (Crassostrea rhizophorae)

L. A. Ribeiro, Santos, L. K. N. S. S., Brito, Jr., P. A., Maciel, B. M., Da Silva, A. V., and Albuquerque, G. R., “Detection of Toxoplasma gondii DNA in Brazilian oysters (Crassostrea rhizophorae)”, vol. 14, pp. 4658-4665, 2015.

The aim of this study was to detect evidence of Toxoplasma gondii using polymerase chain reaction (PCR)-based techniques in oysters (Crassostrea rhizophorae) obtained from the southern coastal region of Bahia, Brazil. A total of 624 oysters were collected, and the gills and digestive glands were dissected. Each tissue sample was separated into pools containing tissues (of the same type) from three animals, leading to a total of 416 experimental samples for analysis (208 samples each from the gills and digestive glands).

Sequence variation in the Toxoplasma gondii eIF4A gene among strains from different hosts and geographical locations

Toxoplasma gondii is an opportunistic protozoan parasite that infects a wide range of animals, including humans. The T. gondii eukaryotic translation initiation factor 4A (eIF4A) protein is expressed in the tachyzoite, but its expression is markedly downregulated in the bradyzoite, and it is therefore considered to be associated with tachyzoite virulence.

Characterization of the Toxoplasma gondii hsp60 gene sequences from different hosts and geographical locations

J. Lu, Zhou, D. H., Chen, J., Zhang, N. Z., Wang, R. A., Weng, Y. B., and Zhu, X. Q., “Characterization of the Toxoplasma gondii hsp60 gene sequences from different hosts and geographical locations”, vol. 13, pp. 6906-6911, 2014.

The intracellular protozoan Toxoplasma gondii is one of the most successful parasites, with the ability to invade all warm-blooded animals, including humans. T. gondii heat shock protein 60 (TgHSP60) plays an important role in intracellular survival and in the differentiation of the parasite, and is also recognized as being associated with its virulence. In the present study, we examined sequence variation in the hsp60 coding region among five T.
