The causative agent of braxy is Cl. septicum. It usually affects lambs. The agent is a normal inhabitant of soil and is frequently found in the faeces of herbivores. Braxy is a form of malignant oedema of abomasums. The incidence is highest in hill tracts. The exact conditions of microenvironment which favours the growth of organism are unknown. The disease occurs in an acute form. The animals die without showing symptoms however the affected animals may show signs of abdominal pain and frothing from mouth and diarrhoea due to toxaemia. On post-mortem examination, inflammation of stomach wall characterized by the congestion, ulceration and necrosis may be observed. Laboratory examination include cultural examination of cut surfaces of the abomasal wall or heart blood. The disease can be controlled by inoculation of formalinized whole culture of Cl. septicum to the animals which confers a satisfactory immunity.
