Clostridial infections, putrid infections with aerobic and anerobic growing germs, air forced into the tissue during the primary trauma and the formation of gas by contact of the wound with aluminium, H2O2 and gasoline may be causes for the formation of gas and oedema in the tissues. Only infections with Clostridia are gas gangrene. We must differentiate the clostridial cellulitis from the clostridial myositis. Bacterioscopy allows a rapid differentiation to be made between putrid and clostridial infection. Beside intensive care and antibiotics, putrid infections demand an early extensive incision, for gas gangrene the radical excision of the damaged tissue is required. The effect of hyperbaric oxygenation is still under discussion. It can never replace surgical treatment.

Prompt and early microbiological differential diagnosis is essential for clinical presumptive diagnosis of gas gangrene. The differential diagnosis includes clostridial myositis (gas gangrene), clostridial cellulitis and other gas producing infections. Examination of Gram preparation (bacterioscopy) and detection of the etiologic agent in muscle specimens are necessary for diagnosis. Clostridium perfringens has been shown as the causative organism of gas gangrene. A method is reported which allows the screening and identification of Clostridium perfringens from clinical specimens in a few hours. Using a medium yielding optimal growth and toxin production, pure cultures are centrifuged and subjected to rapid tests (detection of beta-galactosidase, phospholipase C).

Malignant edema (clostridial myositis) was diagnosed in 9 horses with signs of illness that included fever, depression, painful muscular swellings, and toxemia. The infection followed intramuscular injections in 8 horses and developed in a puncture wound in 1 horse. Treatment consisted of surgical fenestration of the involved muscle, high doses of penicillin, nonsteroidal anti-inflammatory agents and analgesics, and supportive fluid therapy. Five horses recovered and 4 died. Those that died had advanced signs of the disease at admission.

A 13-year-old girl incurred gas gangrene after intramuscular injection of adrenaline to the buttock. Clinical evidence of very severe pain at the site of injection with septicemia and collapse within 24 to 48 hours should arouse the suspicion of clostridial myositis rather than pyogenic infection. Early diagnosis and treatment by adequate excision of necrotic muscle (with a wide margin of normal-appearing muscle) can prevent loss of life or limb in these patients.

Clostridia are anaerobic Gram-positive bacilli that can be isolated from the soil and the intestinal tract of humans. These microorganisms are recognized as the cause of devastating soft tissue infections, such as cellulitis, myositis, and gas gangrene. However, such bacteria may also be involved in various postoperative orthopedic infections, including prosthetic joint infection. We present three clinical cases of clostridial orthopedic infection and review the related medical literature.

This review summarizes the microbiology, management, and prevention of myositis. Muscular infections frequently occur in areas of the body that have been compromised or injured by a foreign body, trauma, ischemia, injection of illicit drug, malignancy, or surgery. These infections can develop very rapidly to life-threatening systemic illness. The predominant pathogens are Staphylococcus aureus, Group A streptococci (GAS), gram-negative aerobic and facultative bacilli, and the indigenous aerobic and anaerobic cutaneous and mucous membranes local microflora. Pyogenic myositis can be classified into either GAS necrotizing myositis, clostridial myonecrosis (gas gangrene), or nonclostridial (crepitant) myositis. Intensive surgical and medical therapy that includes the administration of intravenous fluids and antimicrobial therapy is an essential element in management of muscle infection.

Infectious myositis, an infection of the skeletal muscle(s), is uncommon. This clinical entity may be caused by viral, bacterial, fungal, and parasitic pathogens. Viral etiologies typically cause diffuse myalgias and/or myositis, whereas bacteria and fungi usually lead to a local myositis which may be associated with sites compromised by trauma or surgery and are more common among immunocompromised patients. Localized collections within the muscles are referred to as pyomyositis. Other pyogenic causes of myositis include gas gangrene, group A streptococcal myonecrosis, and other types of non-clostridial myonecrosis. Early recognition and treatment of these conditions are necessary as they may rapidly become life-threatening.

Infectious muscle diseases have very different aetiologies. The viral myositides are proved by clinical and laboratory evidences in various etiologic settings (Influenza A and B, Coxsackie and HIV). The bacterial myositis was considered in the near past a tropical disease, but in our days with migration of people from South to North and the endemia of AIDS it became a problem of the "civilized" world. On the other hand, tuberculous endemia in Central-Eastern Europe, including Romania, results in quite high incidence of osteoarticular tuberculosis. In this section the authors take into consideration some clinical entities, such as psoas abscess, postanginal sepsis, beta-haemolytic streptococcus infection and that caused by Koch bacillus. Other rare musculoskeletal infections such as gas gangrene and non-clostridial anaerobic myonecrosis are also reviewed. Immune depression caused by underlying diseases, therapies, alcoholism or old age is often encountered. The parasitic aetiologies include infestations with Trichinella spiralis, Cysticercus cellulosae, Toxoplasma and Amoeba. The contribution of imagistic methods to diagnosis is emphasised. Ultrasonography associated with CT imaging are usually used, while MRI should be reserved for cases in which axial skeleton is involved. The management is based on appropriate antibiotic therapy and surgery.

This review summarizes the microbiological aspects and management of soft tissue and muscle infections. The infections presented are: impetigo, folliculitis, furunculosis and carbuncles, cellulitis, erysipelas, infectious gangrene (includes necrotizing fasciitis or streptococcal gangrene, gas gangrene or clostridium myonecrosis, anaerobic cellulites, progressive bacterial synergistic gangrene, synergistic necrotizing cellulitis or perineal phlegmon, gangrenous balanitis, and gangrenous cellulitis in the immunocompromised patient), secondary bacterial infections complication skin lesions, diabetic and other chronic superficial skin ulcers and subcutaneous abscesses and myositis. These infections often occur in body sites or in those that have been compromised or injured by foreign body, trauma, ischemia, malignancy or surgery. In addition to Group A streptococci and Staphylococcus aureus, the indigenous aerobic and anaerobic cutaneous and mucous membranes local microflora usually is responsible for polymicrobial infections. These infections may occasionally lead to serious potentially life-threatening local and systemic complications. The infections can progress rapidly and early recognition and proper medical and surgical management is the cornerstone of therapy.

Infections with Clostridium perfringens usually manifest locally or spread to sepsis with multiorgan involvement, hemolysis or septic shock. Central nervous system (CNS) manifestations are rare and most frequently comprise meningitis with or without pneumencephalon, encephalitis, plexitis, cerebral abscess, or subdural empyema. The course of CNS affections is usually foudroyant and the outcome fatal. Neuromuscular manifestations of C. perfringens infections are much more frequent than CNS manifestations and comprise myonecrosis (gas gangrene), rhabdomyolysis, myositis, fasciitis, affection of the neuromuscular transmission, or affection of the peripheral nerves. C. perfringens infections usually start from the site of a recent surgical wound or trauma, a gastrointestinal or urogenital problem, or occur in association with malignancy. In quite a number of cases the source of origin remains speculative. Treatment of choice is surgical debridement of the infectious focus with radical removal of all necrotic tissue, resection of the corresponding lymphatics in addition to antibiotic therapy with penicillin G, aminoglycosides, or clindamycin or hyperbaric oxygenation. Despite these therapeutic options, the prognosis of CNS and neuromuscular involvement in an infection with C. perfringens is still poor. Only focal infections or clostridial brain abscesses may eventually have a more favorable outcome, if surgery and antibiotics are instantly provided. Generally, early recognition of the infectious agent is of paramount importance to prevent from spreading and the development of severe hemolysis, septic shock, or death.
