Besnoitia besnoiti is a protozoan parasite known to cause important economic losses in the cattle industry in Africa, Asia and the Mediterranean area. In the last years, (re-) emergence of the parasite has been reported in France, Germany, Hungary and Italy with in some cases, establishment of an endemic infection. In this article, the first case of besnoitiosis in Belgium in a Blonde d’Aquitaine bull imported from the south of France is described. Additionally, a brief overview of the epidemiology of the disease is provided.

Hernia diafragmatica is een zeldzame aandoening bij het rund en wordt gekenmerkt door een variabel klinisch beeld met hoofdzakelijk symptomen van voorste stenose. Aan de hand van vier gevallen bij het rund worden in dit artikel de oorzaken, de symptomen, de diagnose en de behandeling van deze aandoening besproken. Volgens de literatuur is het mogelijk de diagnose preoperatief te stellen en is een succesvolle behandeling mogelijk. Er wordt een vergelijking gemaakt van de bevindingen bij deze vier casuistieken en de literatuur.

This paper describes two infections with Clostridium tetani (C. tetani). One outbreak occurred after dehorning of calves, the second infection happened after ear tagging of a goat. In the first case 3 young Holstein Friesian calves showed generalized stiffness, severe lock-jaw and bloat two weeks after dehorning. The thermal dehorning wounds were identified as the infection sites of C. tetani by bacterial culture and PCR. The second case was a three-year old male castrated goat, with generalized stiffness. The animal had been ear tagged one week prior to the onset of the symptoms. C. tetani could be cultured from pus on the ear tag. Treatment was attempted in two calves and the goat. Wounds were debrided and disinfected, penicillin and anti-tetanus serum were administered and polyionic perfusions provided. In addition, the goat was vaccinated against tetanus. The goat and one calf fully recovered after 36 and 8 days respectively. To the authors' knowledge a tetanus outbreak in association with thermal dehorning has not been described previously. Also ear tagging as a possible cause for C. tetani infection has not been described in goats.
