Transmissão congênita em cabras reinfectadas com Toxoplasma gondii

This study evaluated the potential of congenital transmission in goats experimentally infected and reinfected with Toxoplasma gondii, in three gestational stages (initial, intermediate and final). Of the 25 non-pregnant females negative for T. gondii, 20 were orally inoculated with 2.5 x 103 T. gondii ME49 oocysts. Of these, 15 pregnant females chronically infected were reinoculated, via oral, with 2.5 x 103 T. gondii VEG oocysts. Five experimental groups were formed (n=5): I, II and III (reinoculations in the initial, intermediate and final gestational stage, respectively), IV (inoculation) and V (no inoculation). Clinical and serological exams (IgG IFAT [indirect immunofluorescence antibody test]) in different days of evaluation, and bioassay and PCR were performed in all goats. In the infected goats with T. gondii a peak of 40.2°C (IV) at nine, seroconversion (IgG≥64) at 21 and stabilization (IgG<1024) at 119 days postinoculation were observed. In the reinfected goats with T. gondii occurred an increase in IgG titers (≥1,024) at 28 (I), 7 (II) and 3 (III) days post-reinoculation. During kidding were observed only in the reinfected groups: dystocia, malformation body, stillbirth and weakness, and IgG anti-Toxoplasma were detected in all and in some offsprings of the reinfected and infected goats, respectively. Tissue parasitism by T. gondii was diagnosed by bioassay and PCR in infected and reinfected goats and in their offspring. The congenital toxoplasmosis was possible in goats chronically infected and reinfected with T. gondii. The primary infection with T. gondii did not protect the pregnant goats against congenital disease resulting from toxoplasmic reinfection, in different gestational stages (initial, intermediate and final).

Study on Chagas disease occurrence in the municipality of Monte Negro, State of Rondônia, Brazilian Amazon

Introduction: Studies on Chagas disease deal with the perspective of its occurrence in the Amazon region, which is directly correlated to the population growth and the spread of the bug biotope. The state of Rondônia has an immense source of vectors (Triatomine) and reservoirs of Trypanosoma cruzi. Environmental changes brought forth by the deforestation in the region may cause vector behavior changes and bring these vectors to a closer contact with humans, increasing the probability of vector infection. Methods: This study was carried out to check the occurrence of Chagas disease in the municipality of Monte Negro, Rondônia, Brazil, based on a random sampling of the farms and people wherein blood collection from the population and capturing triatomines were done. The blood samples were submitted to serologic tests to detect antibodies of the IgG class against T. cruzi. The triatomines that were collected had their digestive tract checked for the presence of trypanosomatidae with morphology resembling that of the T. cruzi. Results: The population examined was mostly from other states. From the 322 bugs examined on the microscope, 50% showed parasites with morphology compatible with T. cruzi. From the serology of 344 random samples of human blood, 1.2% was found positive, 6% showed inconclusive results, and 92.8% were negative. Conclusions: Monte Negro shows low prevalence of human infection by T. cruzi and none active vector transmission; however, preventive and surveying measures, which are not performed until now, shall be taken due to the abundance of vectors infected by trypanosomatidae.
