Abstract
A szerzők bemutatják a sertések vérzéses bél szindrómáját (hemorrhagic bowel syndrome, HBS), amely leginkább a jól fejlődő hízósertéseket érintő, előzmények nélküli bélvérzéssel és hirtelen elhullással járó kórkép. Intenzív sertéshizlalás körülményei között súlyos gazdasági veszteséget okozhat, ezért vizsgálata az utóbbi időben növekvő érdeklődésre tesz szert. A HBS komplex, multifaktorális betegség, kóroktanában tartási, takarmányozási, menedzsment tényezők, valamint a bélmikrobióta egyensúlyának eltolódása (pl. clostridiumok túlsúlya) egyaránt szerepet játszanak. A védekezés kizárólag megelőzésen, elsősorban a HBS-t kiváltó takarmányozási és menedzsmenttényezők kiküszöbölésén alapul. | The authors review the occurrence, etiology, predisposing factors, clinical findings, necropsy, diagnostics and ways of prevention of the hemorrhagic bowel syndrome (HBS). The disease mainly affects well-developed fattening pigs between 4 and 6 months of age and causes sudden deaths without any previous clinical signs. Due to the economic damage, the investigation of the illness is of increasing veterinary interest. The term 'haemorrhagic bowel syndrome' is generally used when finishing pigs die suddenly without a history of diarrhea or other clinical signs and the necropsy shows marked pallor of the skin, abdominal distension, and a thin-walled small intestine with either clotted or non-clotted blood in the lumen. In some cases, intestinal volvulus also described which could be the result of agonic spasm. The large intestine contains terry fecal material without the signs of gastric ulcer or any other disease. While the exact cause of the disease is not yet fully understood, it can be said that it is a multifactorial syndrome. Both infectious agents and non-infectious factors (i.e housing and management, feeding, genetics, seasonal effects) are involved in the pathogenesis of HBS. The clinical manifestation of the disease is most often explained by feeding rations with high fermentability, especially in liquid feeding system with high whey content, where sudden death in the absence of intestinal torsion can be explained by hypovolemic shock due to excessively high intraabdominal pressure. Another approach is that if, for some reason, normal gut flora is overgrowing and/or altered, this can lead to an overproduction of toxic substances and harmful compounds, with consequences such as acidosis, endotoxemia, enterotoxemia and death. The diagnosis of the HBS is based on the exclusion of other diseases causing sudden death, the most important of which is intestinal torsion. Careful necropsy of the dead animals is essential for differential diagnosis.
