| occurrence of antibodies to neospora caninum and toxoplasma gondii in dogs from pernambuco, northeast brazil. | a serological survey was carried out to assess the occurrence of anti-neospora caninum antibodies in dogs from the state of pernambuco. a total of 625 serum samples of dogs (289 from paulista, 168 from amaraji and 168 from garanhuns) were tested by an immunofluorescence antibody assay for the detection of anti-n. caninum antibodies. a total of 177 (28.3%; ic 95%, 24.9-32.1) samples were positive. the seropositivity rates found in paulista, amaraji and garanhuns were 26% (ic 95%, 21-31.4), 26.2% ... | 2008 | 18723288 |
| toxoplasma gondii and neospora caninum in sparrows (passer domesticus) in the northeast of brazil. | toxoplasma gondii is a cosmopolitan protozoan parasite of warm-blooded animals that causes high rates of infection in mammals and birds. sparrows (passer domesticus) are synantropic birds which are distributed worldwide. they serve as intermediate hosts for the parasite but are quite resistant to toxoplasmosis. the aims of this study were to determine the frequency of t. gondii infection in sparrows using serologic and molecular tests, and to investigate related parasites, such as neospora canin ... | 2010 | 19879051 |
| serological survey of neospora caninum in small ruminants from pernambuco state, brazil. | neospora caninum infection is an important cause of bovine abortion as well as neonatal mortality in goats and sheep. a serological survey for antibodies against n. caninum in goats and sheep was carried out in the municipality of ibimirim, pe, northeastern brazil. the imunnofluoresce antibody test showed that 26.6% (85/319) of the goats and 64.2% (52/81) of the sheep were positive. serologic reactivity was associated with age in goats (p < 0.01) and sheep (p > 0.05), with increasing rates in ol ... | 2011 | 21961757 |
