| 4. | Descripción | Resumen | Abstract: Background: Toxoplasma gondii, the causative agent of toxoplasmosis, can infect a broad range of hosts, including humans, and can lead to abortions, neonatal mortality and neurotoxoplasmosis. Thus, knowledge of the biological and molecular aspects of the parasite is important for better integration with epidemiological studies. Methods: A serologic screening of 58 free-range chickens (Gallus gallus domesticus) grown for human consumption in Espírito Santo State, Brazil, by means of indirect haemagglutination assay (IHA). Thirteen chickens tested positive for anti-T. gondii antibodies. Of these, five seropositive animals were selected, and their hearts and brains were extracted and individually used for isolation by mouse bioassay. Ten isolates were obtained and biologically characterised in BALB/c mice inoculated with 101, 102, 103 or 104 tachyzoites. All isolates were classified as virulent or intermediately virulent. Results: Among the isolates obtained in this study, none were considered avirulent, and only two of the heart samples (TgCkBrEs1h and TgCkBrEs5h) were considered intermediately virulent (Table 2), even though survival only occurred at the lowest dose (101 tachyzoites). Conclusion: These results contribute to the knowledge of the T. gondii strains circulating in the state of Espírito Santo and already identified in other parts of Brazil and the world. |
