ABSTRACT
Introduction: Toxoplasmosis is a zoonosis caused by Toxoplasma gondii worldwide distributed [1]. In both, men and animals, the infection with T. gondii can lead to important pathologies [2]. The study of alternative treatments is important to set new therapeutic protocols, especially for the prevention of congenital toxoplasmosis. Aim: This study evaluated the effect of a biotherapic 7DH T. gondii in mice infected with T. gondii. Material and methods: The study was approved by the Ethics Committee for Animal Experimentation of the Universidade Estadual de Maringá – Protocol n° 036/2009. Fourteen mice were used – swiss male aged 57 days divided into two groups according to the treatment (or its diluent biotherapic): BIOT-200DH and Control (cereal alcohol-7%).The biotherapic was prepared with homogenized mouse brain (20 cysts of T.gondii/100μL-average 242 bradyzoites / cyst), according to the Brazilian Homeopathic Pharmacopoeia [3] in laminar flow. The experiment was performed as a blind randomized controlled trial. The animals were treated for 3 days immediately prior to infection. The oral treatment schedule was of 0.1mL/4x/ day, on the first day, followed by 2x/day. Animals aged 57 – 59 days were treated with biotherapic and were clinically evaluated. The animals were orally infected at the age of 60 days (20 cysts ME49-T. gondii). Within18-21 days of infection the clinical parameters were evaluated. On the 55th day of infection the eye fundus was examined (Ophthalmoscope Welch Allyn ®) and the intraocular pressure was measured (Tonometer TONO-PEN ® XL). After 60 days of post-infection the animals were killed in a chamber saturated with halothane, the brains were homogenized and resuspended in 1 ml of saline solution. The cysts were counted according to a rate of 25 mL of suspension, covered with 24x24 mm glass, examined in its full length. Results and discussion: The table 1 summarizes the clinical data. There was no significant difference among the groups for clinical parameters during treatment, although it was recorded the death of an animal in the biotherapic 7DH group. The dead animal presented distended stomach and liquid feces in the intestine. After the infection it was observed reduction of water consumption (p
