Rare aneurysm of the hepatic artery with overlap to the gastroduodenal artery in very uncommon coincidence with occurence of hepatomesenteric trunk.

Background: Aneurysms of visceral arteries are rare, but in case of rupture, they are potentially life threatening. In addition, there is a broad spectrum of the anatomic variability for the arterial supply of the liver.

Methods: Based on a real but very rare clinical case, including its diagnostic management and short-term course, the extraordinary coincidence of (i) an aneurysm of the gastroduodenal artery at its branching off from the hepatic artery and (ii) occurrence of hepatomesenteric trunk is described by the means of a scientific medical case report as well as an adequate and selective literature search.

Expression levels of immune markers in Actinobacillus pleuropneumoniae infected pigs and their relation to breed and clinical symptoms.

Background: In pigs little is known about the role of innate immune defence in bacterial infections of the respiratory tract, despite their major role in pig production. In the present study we characterized and compared in vitro and in vivo activation of immune markers of different pig breeds 7 days before, and 4 and 21 days after an experimental aerosol infection with Actinobacillus (A.) pleuropneumoniae.
