Variolation Campaigners in London for expanded vaccination in the developing world Early attempts to prevent smallpox involved deliberate inoculation with the disease in hopes that a mild case would confer immunity. Originally called inoculation, this technique was later called variolation to avoid confusion with cowpox inoculation vaccination when that was introduced by Edward Jenner. Although variolation had a long history in China and India, it was first used in North America and England in Reverend Cotton Mather introduced variolation to Boston, Massachusetts, during the smallpox epidemic. Zabdiel Boylston to try it. Boylston first experimented on his 6-year-old son, his slave, and his slave's son; each subject contracted the disease and was sick for several days, until the sickness vanished and they were "no longer gravely ill". Lady Mary Wortley Montagu introduced variolation to England. She had seen it used in Turkey and, in , had her son successfully variolated in Constantinople under the supervision of Dr. Charles Maitland. When she returned to England in , she had her daughter variolated by Maitland. This aroused considerable interest, and Sir Hans Sloane organized the variolation of some inmates in Newgate Prison. These were successful, and after a further short trial in , two daughters of Caroline of Ansbach Princess of Wales were variolated without mishap.

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 [1], horses [2], sheep and goats [3], and pigs [4], but it is considered to be rare in companion animals [5].

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 [1].

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.
