The aim of the study was to verify under experimental conditions the hypothesis that a reliable protection of piglets against Actinobacillus pleuropneumoniae (App) infection can be obtained by colostrum-derived antibodies and/or a low-dose infection from sows naturally infected with App. Twenty-eight piglets were allocated into four groups. Piglets of groups 1A and 1B were the progeny of App-seronegative sows, piglets of groups 2A and 2B originated from App-seropositive sows. At the age of 4 weeks, piglets in groups 1A and 2A were exposed to a low infection dose with the pathogenic strain of App serotype 9 (4 × 10⁴ CFU/ml). At the...

The total mercury concentrations in four tissues (muscle, intestines, liver and kidney) of aquatic birds (cormorant - Phalacrocorax carbo and great crested grebe - Podiceps cristatus) and Eurasian buzzard (Buteo buteo) were determined by cold vapour atomic absorption spectrometry (CV-AAS) using an Advanced Mercury Analyser AMA 254. The results of the direct CV-AAS analyses of homogenised solid samples were in very good agreement with those obtained by CV-AFS and CV-AAS analyses after acid digestion. Mercury concentrations in the tested tissues of adult populations of great crested grebe and cormorant were nearly twice as...

The assay conditions needed to achieve maximal activity of liver and kidney arginase in diabetic and non-diabetic rats were investigated and compared. The physicochemical and kinetic properties of liver arginase in diabetic and control rats were very similar, those of kidney arginase were significantly different. It was found that preincubation temperature (68°C), preincubation period (20 min), optimum pH (10.1) of liver arginase and K_m (3.2) for its substrate, L-arginine, did not change in diabetic and non-diabetic rats. As a consequence of diabetes, the optimum Mn²⁺ concentration for liver arginase only changed from...

In this study veins that constituted the portal vein were investigated in eight adult Van cats. The portal vein of the Van cat was composed of five peripheral branches which supplied the abdominal organs and two intrahepatic branches at the hepatic porta. The peripheral branches were cranial mesenteric, splenic, gastroduodenal, right gastric and cystic veins. The cranial mesenteric vein was the largest vessel that joined to the portal vein, and was constituted by the caudal pancreaticoduodenal, ileal, ileocolic and jejunal veins. The splenic vein was formed by the left gastric, left gastroepiploic, pancreatic and short gastric veins. The gastroduodenal...

Spontaneous rupture of uterus in the bitch at parturition with evisceration of puppy intestine - a case report

A rupture of one uterine horn at the region of small curvature and placentation was observed in a pregnant 8-year old Schnauzer bitch carrying a single foetus. It occurred at its second parturition. The first whelping at the age of 3 years had been without complications and the bitch reared eleven puppies. The uterine rupture occurred at the puppy's umbilical cord. An urgent obstetrical examination revealed one dead foetus in anterior presentation and ventral position. Caesarean delivery was indicated. Evisceration of puppy's intestine through its ruptured abdominal wall at the umbilical cord could be observed through the uterine wall rupture of 1.5...
