A porcine model was used to examine the potential of human and porcine Staphylococcus aureus isolates to induce haematogenously spread osteomyelitis. Pigs were inoculated in the right femoral artery with one of the following S. aureus strains: S54F9 (from a porcine lung abscess; n = 3 animals), NCTC-8325-4 (a laboratory strain of human origin; n = 3(More)
The prevalence of fibrinous pericarditis detected at slaughter in Danish slaughter pigs is approximately 0.02%. The microbiology and pathology of this disorder was studied through 46 field cases collected at slaughter from May 1994 to August 1995. Mycoplasmas (Mycoplasma hyopneumoniae, M. hyosynoviae and M. hyorhinis) were isolated from the pericardium in(More)
Sepsis is a common and often fatal complication in human patients in intensive care units. Relevant and well characterized animal models of sepsis may provide valuable information on pathophysiological mechanisms and be a mean of testing new therapeutic strategies. Large animal models of Staphylococcus aureus sepsis are rare, even though S. aureus(More)
To elucidate aspects of pathogenesis of congenital infections with Schistosoma japonicum, 5 Danish crossbred sows were infected during late pregnancy with a Chinese isolate of S. japonicum, and 17 of their offspring (fetuses and piglets) were examined 7, 20. 34, 54, and 69 days postinfection (PI). Organ samples were collected for histopathological(More)
Acute respiratory distress syndrome is a common complication in severe sepsis. In pigs, the lungs play an important role in clearing systemic bacterial infections due to pulmonary intravascular macrophages found specifically in pigs. However, this increases the exposure of the porcine lungs to pathogens and potential injury. The authors propose that(More)
The inflammatory response in liver tissue from piglets congenitally infected with Schistosoma japonicum was examined at two different timepoints after infection. The piglets, which were the offspring of three sows infected with 9000 S. japonicum cercariae in the 10th week of gestation, were allocated into two groups (n=9 and 17) killed 5 or 11 weeks after(More)
The aim of the present study was to assess the effect of a congenital Schistosoma japonicum infection on the establishment, fecundity, and pathogenicity of a postnatal challenge infection. Five prenatally S. japonicum-infected piglets received a challenge infection (prenatal + challenge group), 5 prenatally infected piglets were followed without challenge(More)
Tumors of the adrenal glands are among the most frequent tumors in cattle; however, few studies have been conducted to describe their characteristics. The aim of this study was to classify 41 bovine adrenal neoplasms from 40 animals based on macroscopic and histologic examination, including electron microscopy and immunohistochemistry for melan A,(More)
