Over the last years, an increase in cases of Glässer's disease could be noticed, due to intensive farming and the fact that piglets from different farms are commingled (RITZMANN u. HEINRITZI, 2005). The clinical outcome of an infection with Haemophilus parasuis (H. parasuis) can vary. Acute infections can cause abortion and arthritis in sows, whereas chronic lameness can occur in boars (OLIVEIRA u. PIJOAN, 2002). The acute clinical picture is mainly characterized by high fever (>41.5°C), apathy, anorexia, coughing, cyanosis, swollen joints, as well as abdominal breathing. Symptoms such as convulsions, tremor, paralyses, reluctance to move and lateral recumbency point to an affection of the meninges (RAPP-GABRIELSON et al., 2006). In chronic cases, symptoms like coughing, dyspnea, or lameness are most frequently observed. Moreover the clinical picture is characterized by weight loss, kyphotic back line and shaggy as well as dense coat (RAPP-GABRIELSON et al., 2006).
The objective of the present study was to compare the combination therapy of antibiotics (Baytril® RSi) and NSAID (Dinalgen® 60 mg / ml) against Haemophilus parasuis versus the administration of antibiotics (Baytril® RSi).
