“…These stray animals now feed on birds or small wild mammals, including rodents in that area, and this is likely to increase their chances of contracting toxoplasmosis (Dubey and Beattie 1988;Albuquerque et al 2011). It is evident that bovines, such as herbivorous mammals, may have been infected only by widespread oocyst contamination occurring in their habitat, especially on the pastures that they graze (Frenkel 1970;Miller et al 1972;Dubey and Beattie 1988;Dubey and Jones 2008).…”

Serum samples from 169 water buffaloes and 121 beef cattle were analyzed for antibodies to T. gondii by an indirect fluorescent antibody test (IFAT). Positive results were obtained in 27.2% of water buffaloes and 17.4% of cattle. Statistical analysis indicated significant differences between the prevalence in cattle and buffalo (p ≤ 0.05). The highest titres found in positive animals were 1:256 (buffaloes) and 1:64 (cattle). In both bovine species, toxoplasmosis frequency in young animals (less than 2 years old) was lower compared to older individuals, although the differences seen in cattle were not statistically significant.

“…Diğer araştırıcılardan farklı olarak intraperitoneal 10 4 takizoit verilen bıldırcınlardan bir tanesinde pankreasta nekroz alanları tespit edilmiştir. Muhtelif kanatlılarda yapılan deneysel çalışmalarda, histolojik olarak nekrotik hepatit ve splenitis, nefrit, pnömoni, nonsuppuratif ensefalitis, tiflitis, kolitis, adrenalitis, özefagitis ve midede nekrotik yangı görüldüğü rapor edilmiştir (4,13,16,17,20,27,42,46,47). Buna karşılık bu çalışmada da mikroskobik olarak karaciğer, akciğer, beyin ve dalakta benzer şekilde nekrotik yangıya rastlanılmıştır.…”

“…Os animais homeotérmicos são considerados hospedeiros intermediários e os felídeos, os definitivos; nestes os oocistos do parasito se desenvolvem e são eliminados com as fezes para posterior esporulação no ambiente. Em ambos os hospedeiros são encontradas as formas de taquizoítas na fase aguda e de cistos e bradizoítas na fase crônica (1,2) . A infecção em humanos e animais ocorre principalmente pela ingestão de alimentos contaminados com cistos teciduais ou oocistos esporulados e por via transplacentária (3) .…”

Abstract:The aim of this study was to detect antibodies against T. gondii in dogs with clinical signs compatible with toxoplasmosis attended in a veterinary hospital. A serological survey was performed in 598 dogs from 1993 to 2013. The IgG antibodies survey against T. gondii was carried out by means of Indirect Fluorescence Antibodies Test (IFAT); samples with titers ≥16 were considered positive. Among the dogs with clinical signs, 259 (43,31%) were positive for T. gondii with titers varying between 16 to 4096; among the healthy animals, 79 (22.25%) were reagents. The most frequent signals were: neurological (30.43%) and uveitis (8.03%). Among variables race, gender, and age, only the last one affected the observed results with greater frequency f seropositive in elderly dogs. Keywords: clinical signs; dogs; IFAT; serology; Toxoplasma gondii; zoonosis.
