If treated early antibiotics for eight weeks are effective in 80% of people. This often includes the medications rifampicin and streptomycin. Clarithromycin or moxifloxacin are sometimes used instead of streptomycin.

Treatment may also include cutting out the ulcer. This may be a minor operation and very successful if undertaken early. Advanced disease may require prolonged treatment with extensive skin grafting. Surgical practice can be dangerous in the developing countries where the disease is common.

There is no specific vaccine for "Myocobacterium ulcerans". The Bacillus Calmette-Guérin vaccine may offer temporary protection.

No vaccine is available. Simple hygienic precautions like wearing shoes or sandals while working in fields, and washing hands and feet at regular intervals may help prevent the disease.

Recommended regimen is doxycycline 100 mg orally twice a day, alternatively azithromycin 1 g orally once per week or ciprofloxacin 750 mg orally twice a day or erythromycin base 500 mg orally four times a day or trimethoprim-sulfamethoxazole one double-strength (160 mg/800 mg) tablet orally twice a day. All antibiotic regimens should last for at least 3 weeks and until all lesions have completely healed. Normally, the infection will begin to subside within a week of treatment, but the full treatment period must be followed to minimize the possibility of relapse.

According to the CDC 2015 guidelines Azithromycin is the antibiotic of choice.

Drugs like ketoconazole,

voriconazole, and itraconazole are generally employed in treating the infection. Actinomycetes usually respond well to medical treatment, but the eumycetes are generally resistant and may require surgical interventions including amputation.

Adequate footwear is important to prevent trauma. General good health and nutrition also reduce ulcer risk. Adequate and prompt cleansing and treatment of ankle and leg skin breaks is also important. Improving hygiene and nutrition may help to prevent tropical ulcers.

The disease is effectively treated with antibiotics, therefore, developed countries have a very low incidence of donovanosis; about 100 cases reported each year in the United States. However, sexual contacts with individuals in endemic regions dramatically increases the risk of contracting the disease. Avoidance of these sexual contacts, and sexually transmitted disease testing before beginning a sexual relationship, are effective preventative measures for donovanosis.

The CDC recommendation for chancroid is a single oral dose (1 gram) of azithromycin, or a single IM dose of ceftriaxone, or oral erythromycin for seven days.

Abscesses are drained.

"H. ducreyi" is resistant to sulfonamides, tetracyclines, penicillins, chloramphenicol, ciprofloxacin, ofloxacin, trimethoprim and aminoglycosides. Recently, several erythromycin resistant isolates have been reported.

Treatment failure is possible with HIV co-infection and extended therapy is sometimes required.

Prognosis is excellent with proper treatment. Treating sexual contacts of affected individual helps break cycle of infection.

Infected fish should be moved into high quality water, where they may recover if their clinical signs are mild.

If disease occurs eradication is required. Once the disease is eradicated good husbandry, surveillance and biosecurity measures are necessary to prevent recurrence. In countries free of epizootic ulcerative syndrome, quarantine and health certificates are necessary for the movement of all live fish to prevent the introduction of the disease.

Skin ulcers may take a very long time to heal. Treatment is typically to avoid the ulcer getting infected, remove any excess discharge, maintain a moist wound environment, control the edema, and ease pain caused by nerve and tissue damage.

Topical antibiotics are normally used to prevent the ulcer getting infected, and the wound or ulcer is usually kept clear of dead tissue through surgical debridement.

Commonly, as a part of the treatment, patients are advised to change their lifestyle if possible and to change their diet. Improving the circulation is important in treating skin ulcers, and patients are consequently usually recommended to exercise, stop smoking, and lose weight.

In recent years, advances have been made in accelerating healing of chronic wounds and ulcers. Chronic wounds produce fewer growth hormones than necessary for healing tissue, and healing may be accelerated by replacing or stimulating growth factors while controlling the formation of other substances that work against them.

Leg ulcers can be prevented by using compression stockings to prevent blood pooling and back flow. It is likely that a person who has had a skin ulcer will have it again; use of compression stockings every day for at least 5 years after the skin ulcer has healed may help to prevent recurrence.

Treatment is symptomatic, and usually of little value; in most cases, the ulcer heals spontaneously within four to six weeks, sometimes leaving scars. Topical analgesics and anesthetics, as well as topical application of disinfectants/astringents such as potassium permanganate (in sitz baths), is commonly used. In severe cases, a combination of systemic glucocorticoids and broad-spectrum antibiotics has been recommended.

Treatments involve antibiotics that cover for "Pseudomonas aeruginosa". Antipseudomonal penicillins, aminoglycosides, fluoroquinolones, third generation cephalosporins or aztreonam can be given. Usually, the antibiotics are changed according to the culture and sensitivity result. In patients with very low white blood cell counts, Granulocyte-macrophage colony-stimulating factor may be given. Depending on the causal agents, antivirals or antifungals can be added.

Surgery will be needed if there is extensive necrosis not responding to medical treatments.

A presumptive diagnosis of fungal keratitis requires immediate empirical therapy. Natamycin ophthalmic suspension is the drug of choice for filamentous fungal infection. Fluconazole ophthalmic solution is recommended for Candida infection of the cornea. Amphotericin B eye drops may be required for non-responding cases, but can be quite toxic and requires expert pharmacist for preparation. Other medications have also been tried with moderate success. Consult your eye care professional in any case as they will have the best treatment.

The infection typically takes a long time to heal, since the fungus itself is slow growing. Corneal perforation can occur in patients with untreated or partially treated infectious keratitis and requires surgical intervention in the form of corneal transplantation.

Surgical debridement (cutting away affected tissue) is the mainstay of treatment for necrotizing fasciitis. Early medical treatment is often presumptive; thus, antibiotics should be started as soon as this condition is suspected. Given the dangerous nature of the disease, a high index of suspicion is needed. Initial treatment often includes a combination of intravenous antibiotics including piperacillin/tazobactam, vancomycin, and clindamycin. Cultures are taken to determine appropriate antibiotic coverage, and antibiotics may be changed when culture results are obtained.

Treatment for necrotizing fasciitis may involve an interdisciplinary care team. For example, in the case of a necrotizing fasciitis involving the head and neck, the team could include otolaryngologists, speech pathologists, intensivists, infectious disease specialists, and plastic surgeons or oral and maxillofacial surgeons. Maintaining strict asepsis during any surgical procedure and regional anaesthesia techniques is vital in preventing the occurrence of the disease.

Underlying cause of neuropathy is first treated. Necrotic portions of the wound are removed and wound is kept moist at associations. Infected ulcers are administered antibiotics.

Skin grafting is one of the options. It has been shown that ultrasound may increase the acceptance of graft at trophic ulcer sites.

Necrotic tissue should be removed in most pressure ulcers. The heel is an exception in many cases when the limb has an inadequate blood supply. Necrotic tissue is an ideal area for bacterial growth, which has the ability to greatly compromise wound healing. There are five ways to remove necrotic tissue.

1. Autolytic debridement is the use of moist dressings to promote autolysis with the body's own enzymes and white blood cells. It is a slow process, but mostly painless, and is most effective in individuals with a properly functioning immune system.

2. Biological debridement, or maggot debridement therapy, is the use of medical maggots to feed on necrotic tissue and therefore clean the wound of excess bacteria. Although this fell out of favor for many years, in January 2004, the FDA approved maggots as a live medical device.

3. Chemical debridement, or enzymatic debridement, is the use of prescribed enzymes that promote the removal of necrotic tissue.

4. Mechanical debridement, is the use of debriding dressings, whirlpool or ultrasound for slough in a stable wound

5. Surgical debridement, or sharp debridement, is the fastest method, as it allows a surgeon to quickly remove dead tissue.

Internationally, the NPUAP, EPUAP and Pan Pacific Pressure Injury Alliance (Australia, New Zealand, Singapore and Hong Kong) published updated evidence-based clinical practice guidelines in 2014. The guideline was developed by an international team of over 100 clinical specialists and updates the 2009 EPUAP and NPUAP clinical guidelines. The guideline includes recommendations on strategies to treat pressure ulcers, including the use of bed rest, pressure redistributing support surfaces, nutritional support, repositioning, wound care (e.g. debridement, wound dressings) and biophysical agents (e.g. electrical stimulation). Reliable scientific evidence to support the use of many of these interventions, though, is lacking. More research is needed to assess how to best support the treatment of pressure ulcers, for example by repositioning.

Hyperbaric oxygen treatment is sometimes used to treat necrotizing soft tissue infection in combination with antibiotics and debridement, but there is a lack of compelling evidence regarding its efficacy for this purpose.

The main organism associated with ecthyma gangrenosum is "Pseudomonas aeruginosa". However, multi-bacterial cases are reported as well. Prevention measures include practicing proper hygiene, educating the immunocompromised patients for awareness to avoid possible conditions and seek timely medical treatment.

The first line therapy for aphthous stomatitis is topical agents rather than systemic medication, with topical corticosteroids being the mainstay treatment. Systemic treatment is usually reserved for severe disease due to the risk of adverse side effects associated with many of these agents. A systematic review found that no single systemic intervention was found to be effective. Good oral hygiene is important to prevent secondary infection of the ulcers.

Occasionally, in females where ulceration is correlated to the menstrual cycle or to birth control pills, progestogen or a change in birth control may be beneficial. Use of nicotine replacement therapy for people who have developed oral ulceration after stopping smoking has also been reported. Starting smoking again does not usually lessen the condition. Trauma can be reduced by avoiding rough or sharp foodstuffs and by brushing teeth with care. If sodium lauryl sulfate is suspected to be the cause, avoidance of products containing this chemical may be useful and prevent recurrence in some individuals. Similarly patch testing may indicate that food allergy is responsible, and the diet modified accordingly. If investigations reveal deficiency states, correction of the deficiency may result in resolution of the ulceration. For example, there is some evidence that vitamin B12 supplementation may prevent recurrence in some individuals.

The vast majority of people with aphthous stomatitis have minor symptoms and do not require any specific therapy. The pain is often tolerable with simple dietary modification during an episode of ulceration such as avoiding spicy and acidic foods and beverages. Many different topical and systemic medications have been proposed (see table), sometimes showing little or no evidence of usefulness when formally investigated. Some of the results of interventions for RAS may in truth represent a placebo effect. No therapy is curative, with treatment aiming to relieve pain, promote healing and reduce the frequency of episodes of ulceration.

Pentoxifylline is a useful add on treatment to compression stockings and may also help by itself. It works by reducing platelet aggregation and thrombus formation. Gastrointestinal disturbances were reported as a potential adverse effect.

Sulodexide, which reduces the formation of blood clots and reduces inflammation, may improve the healing of venous ulcers when taken in conjunction with proper local wound care. Further research is necessary to determine potential adverse effects, the effectiveness, and the dosing protocol for sulodexide treatment.

An oral dose of aspirin is being investigated as a potential treatment option for people with venous ulcers. A 2016 Cochrane systematic review concluded that further research is necessary before this treatment option can be confirmed to be safe and effective.

Oral zinc supplements have not been proven to be effective in aiding the healing of venous ulcers, however more research is necessary to confirm these results.

There is now considerable evidence to suggest that this disease is an infection. "Mycobacterium ulcerans" has recently been isolated from lesions and is unique to tropical ulcers. Early lesions may be colonized or infected by, "Bacillus fusiformis" (Vincent's organism), anaerobes and spirochaetes. Later, tropical ulcer may become infected with a variety of organisms, notably, staphylococci and/or streptococci. The condition has been shown to be transmissible by inoculation of material from affected patients.
