The aim of the study was an analysis of biochemical changes in the blood and ascites fluid of the dogs with peritonitis. The study was conducted on five dogs with septic peritonitis. The examinations were performed as follows: the history and clinical examination, abdominal ultrasound examination, morphological and biochemical examination of selected blood parameters, abdominocentesis and peritoneal fluid examination. In all the dogs the fluid was turbid and bloody, it had high specific gravity, a high level of leucocyte, high concentration of protein, high activity of LDH and a low concentration of glucose. The results of the analysis of biochemical parameters in the ascites fluid suggest septic peritonitis. In all the affected dogs the fluid from the abdominal cavity was transdute. A low concentration of glucose in the peritoneal fluid is an atypical change in dogs with septic peritonitis. The fluid in septic peritonitis usually had a high concentration of total protein and a high concentration of albumin. In our study in all the cases the fluid had a high activity of LDH. These changes are not only typical of septic peritonitis but very often constitute a helpful element of multivariate analysis of septic peritonitis. The microscopic examination of the ascites fluid revealed large numbers of neutrophils and mononuclear cells. The bacteriological examination from the ascitic fluid of dogs showed positive cultures in all the cases. In the fluid from the affected dogs we isolated: Escherichia coli, Clostridium spp., Clopsylo-oxytata, Citrobacter sreundii, Streptococcus constellatus, Peptostreptococcus anaerobius and Enterococcus spp.. In all the cases bacterial flora in the abdominal cavity was mixed.
