Clostridial Myositis and Myonecrosis Gas Gangrene For clostridial myositis and myonecrosis gas gangrene or spreading clostridial cellulitis with systemic toxicity or a presumptive diagnosis of either the preferred treatment is a combination of hyperbaric oxygen HBO2 , surgery, and antibiotics.
Clostridial myositis and myonecrosis or gas gangrene is an acute, rapidly progressive, non-pyogenic, invasive clostridial infection of the muscles, characterized by profound toxemia, extensive edema, massive death of tissue, and a variable degree of gas production.
Welch in It is not known if and what these microorganisms add to the disease process. The essential role of alpha-toxin in the pathogenesis of gas gangrene was recently confirmed by Williamson and Titball, 5 who developed a genetically engineered vaccine against alpha-toxin. Perfringens has been published recently by Shimizu et al. This condition results in an area with a low O2 tension where clostridial spores can develop into the vegetative form.
It destroys platelets and polymorphnuclear leukocytes and causes widespread capillary damage and is often lethal. The other exotoxins are synergistic and enhance the rapid spread of infection by destroying, liquefying, and dissecting healthy tissue.
The clostridial organisms surround themselves with toxins. Local host defense mechanisms are abolished when the toxin production is sufficiently high. This results in fulminating tissue destruction and further clostridial growth. Stevens et al 14 investigated the role of theta-toxin in the pathogenesis of clostridial gas gangrene.
They found evidence for the suggestion that theta-toxin in high concentrations is a potent cytolysin and promotes direct vascular injury at the site of infection. The rapid tissue necrosis associated with C. An extensive and updated review about the role of clostridial toxins in the pathogenesis of gas gangrene was given by Stevens and Bryant.
Eaton et al 18 have further described the crystal structure in combination with the working mechanisms of alpha toxin. In conjunction with previous findings, almost the whole working mechanism with the structure of their toxin is known now. Stevens et al, 19 also showed evidence that alpha- and theta-toxins differentially modulate the immune response and induce acute tissue necrosis in clostridial gas gangrene.
Much more has become known in recent years about the action and also the interaction between the various clostridial toxins in the onset and progression of gas gangrene. Despite emergency treatment, the animal died in only a few minutes.

Clostridium septicum, Clostridium perfringens type A, Clostridium chauvoei, Clostridium sordellii and Clostridium novyi type A, alone or combined, are responsible for malignant edema and gas gangrene.
Clostridial myositis is often recognized as an acute, generally fatal toxemia in cattle , horses , sheep and goats , and pigs , but it is considered to be rare in companion animals .
When etiological procedures have been performed, they have been based on phenotypic methods using isolation, biochemical and morphological characteristics [7,8], which are considered to be laborious and time consuming, require trained personnel, and may provide inaccurate results .
This paper describes an unusual myositis by C. Clinical examination revealed a cutaneous abscess in the left foreleg and several rounded lesions on the abdominal and limb areas, which are symptoms compatible with myiasis. Furthermore, the animal showed weak, dyspnea and fever App Store.
