[Toxoplasma gondii in brains of pigs commercialized at the Municipality of Campos dos Goytacazes in the State of Rio de Janeiro, Brazil].
Brain samples of 12 pigs commercialized for food consumption at the Municipality of Campos dos Goytacazes in the State of Rio de Janeiro were examined for the presence of Toxoplasma gondii. Brain sample of each pig was grinded and submitted to peptic digestion. One ml of the homogenate of each sample was inoculated in three albino mice, and this procedure was repeated 24 hours later. Inoculated mice were observed during six weeks. Dead mice or those that presented clinical signs suggestive of the disease, were examined for the presence of tachyzoites in peritoneal exudates or tissue cysts in their brains. The percentage of positives brains was 50%, which is a confirmation that pigs could be considered as a potential source of infection of T. gondii for humans at this Municipality.
