In a retrospective study on 265 cases of sporadic bovine abortions, stillbirths, and neonatal deaths in Atlantic Canada (1990 to 2001), an etiological diagnosis was made in 117 cases (44.2%). The cases were divided into 2 groups: 234 abortions, and 31 stillbirths and neonatal deaths. Identified causes of abortion were bacteria (24.4%), fungi (6.8%), viruses(More)
This experiment was conducted to assess the changing patterns and relative values of acute phase proteins and inflammatory cytokines in experimental caprine coccidiosis. Eighteen newborn kids were allocated to 3 equal groups. Two groups, A and B, were inoculated with a single dose of 1×10(3) and1×10(5) sporulated oocysts of Eimeria arloingi, respectively.(More)
The progressive morphohistopathologic changes, distribution pattern of lesions and ultrastructural characteristics in Eimeria arloingi infection were investigated in experimentally infected kids. The 18 newborn animals allocated to 3 equal groups. Two of groups, A, B were inoculated with a single dose of 1 × 103 and1 × 105 sporulated oocysts of E. arloingi,(More)
In this study the tachyzoite yields of Neospora caninum were compared in two cell lines: Vero (African Green Monkey Kidney) and suspension culture of murine macrophage (J774) cell lines. Then, N. caninum were continuously passaged in these cell lines for 3 months and the effect of host cells on virulence of tachyzoites was assessed by broiler chicken(More)
In order to provide information on hematological and biochemical changes in Eimeria arloingi infection, eighteen newborn kids were allocated to three equal groups. Two groups, A and B were inoculated with a single dose of 1 × 10(3) and 1 × 10(5) sporulated oocysts of E. arloingi, respectively. The third group C remained uninfected as control. Blood samples(More)
To date, despite the limited information about the role of birds in Neospora caninum infection, there are no reports regarding the role of broiler chickens. In the present study, an experimental infection with N. caninum NC-1 isolate was conducted in embryonated eggs from 70 Lohman broiler chickens randomly divided into seven equal groups. At 8 days of(More)
Bone marrow is the most important source of mesenchymal stem cells (MSCs). Significant development in the comprehension of MSCs biology has opened the way to their clinical use. The object of this study was to establish a method for karyotyping of canine MSCs. We examined the effect of the increase in passage number on the chromosome and appearance of MSCs.(More)
The diagnostic characteristics of immunohistochemistry (IHC) and polymerase chain reaction (PCR) methods were studied in the tissues of broiler chicken embryos experimentally infected by Neospora caninum. An infection with N. caninum NC-1 isolate was conducted in 70 broiler chicken embryonated eggs randomly divided into seven equal groups. After 8 days of(More)
In this study, 30 sheep from a flock suddenly showed acute neurological symptoms associated with more than 30 % mortality. At necropsy, thickening associated with congestion and turbidity of meningeal membranes particularly on cerebellum, focal to multifocal necrotic areas and whitish spots measuring 1 to 3 cm in diameter were observed in the cortex of(More)
A 7-year-old male Persian cat was referred for necropsy examination a with history of progressive abdominal distention, dysuria, polyuria, colic and death. At necropsy examination, a raised white unencapsulated mass (3×6×4cm) was found on the mucosal surface of the bladder. The mass was lobulated with soft consistency similar to that of adipose tissue.(More)
