| occurrence of anti-neospora caninum and anti-toxoplasma gondii igg antibodies in goats and sheep in western maranhão, brazil. | neosporosis and toxoplasmosis are parasitic diseases which can cause reproductive problems in goats and sheep. the current study aimed to determine the occurrence of anti-neospora caninum and anti-toxoplasma gondii igg antibodies in goats and sheep from the districts of amarante do maranhão and buritirana, imperatriz microregion, western area of maranhão state, northeastern brazil, and to assess factors associated to infection by these etiologic agents. blood samples from 110 animals (46 goats a ... | 2011 | 22166386 |
| genetic diversity of toxoplasma gondii isolates from chickens from brazil. | until recently, toxoplasma gondii was considered clonal with very little genetic variability. recent studies indicate that t. gondii isolates from brazil are genetically and biologically different from t. gondii isolates from usa and europe. in the present study, we retyped 151 free range chicken isolates from brazil including 117 newly isolated samples from 11 geographically areas (alagoas, bahia, ceará, maranhão, paraná, pernambuco, rio de janeiro, rio grande do norte, são paulo, sergipe, and ... | 2008 | 18804329 |
| toxoplasma gondii isolates from free-range chickens from the northeast region of brazil. | the prevalence of toxoplasma gondii in free-ranging chickens is a good indicator of the prevalence of t. gondii oocysts in the soil because chickens feed from the ground. the prevalence of t. gondii in 152 free-range chickens (gallus domesticus) from 22 municipalities in 7 northeastern states (pernambuco, rio grande do norte, maranhão, bahia, ceará, sergipe, and alagoas) of brazil was determined. antibodies to t. gondii were assayed by the modified agglutination test (mat); 81 (53.3 %) chickens ... | 2009 | 18578589 |
