When was Buruli ulcer first discovered?
First described by Sir Albert Cook in 1897 in Uganda, it was not until the 1930s that Australian scientists led by Peter MacCallum first succeeded in culturing the organism from lesions of patients from the Bairnsdale region. The name Buruli comes from an area of Uganda where many cases were reported in the 1960s.
Where is Buruli ulcer found?
Buruli ulcer is a disease caused by the bacterium Mycobacterium ulcerans. It mainly affects the skin but can also affect the bone. Cases are generally seen in the tropics, primarily in West Africa and Australia. Infection often leads to ulcers on the arms or legs, which can also destroy skin or soft tissue.
How is Buruli ulcer diagnosed?
Buruli ulcer is diagnosed by taking swabs from the ulcerated area. If there are no ulcers, the skin can be biopsied. These samples are then tested for Mycobacterium ulcerans.
How is Buruli ulcer transmitted?
Mosquito bites and puncture wounds are likely to transmit the bacteria that cause Buruli ulcer, a disfiguring infectious disease in humans. Buruli ulcer spreads via mosquito bites and puncture wounds, researchers have found. This infectious disease is spreading in areas near Melbourne, Australia.
Why is it called the Bairnsdale ulcer?
Buruli (also known as Bairnsdale) ulcer is a skin disease caused by the bacterium Mycobacterium ulcerans. The toxins made by the bacteria destroy skin cells, small blood vessels and the fat under the skin, which leads to ulceration and skin loss.
Why is it called Buruli ulcer?
Buruli ulcer is caused by skin infection with bacteria called Mycobacterium ulcerans. The mechanism by which M. ulcerans is transmitted from the environment to humans is not known, but may involve the bite of an aquatic insect or the infection of open wounds….

Can Buruli ulcer be cured?
Most Buruli ulcers can be treated with a course of specific oral antibiotics. Surgery is sometimes used in combination with antibiotic therapy. If surgery is required, a small amount of surrounding healthy tissue is also cut out to make sure the infection is completely removed.
Is Buruli ulcer Painful?
Buruli ulcer often starts as a painless swelling (nodule), a large painless area of induration (plaque) or a diffuse painless swelling of the legs, arms or face (oedema). The disease may progress with no pain and fever.
What does Bairnsdale ulcer look like?
Symptoms of Buruli ulcer A spot that looks like a mosquito or spider bite forms on the skin (most commonly on the limbs). The spot grows bigger over days or weeks. The spot may form a crusty, non-healing scab. The scab then disintegrates into an ulcer.
Is a Buruli ulcer itchy?
The first sign of Buruli ulcer is usually a painless, non-tender nodule or papule. It is often mistaken for an insect or spider bite and is sometimes itchy. The lesion may occur anywhere on the body, but it is most common on exposed areas of the limbs.
What is the incubation period of Buruli ulcer?
Results: Among the 20 new cases identified in short-term visitors, the mean incubation period was 143 days (4.8 months), very similar to the previous estimate of 135 days (4.5 months). This was despite the predominant exposure location shifting from the Bellarine peninsula to the Mornington peninsula.
What are the complications of Buruli ulcer?
What are the complications of Buruli ulcer? Tissue destruction can be extensive (involving up to 15% of the patient’s skin surface) and secondary infection may occur. Other complications include osteomyelitis (infection of the bone) and metastatic lesions (the spread of the wounds to distant sites).
Who was the first person to discover Buruli ulcer?
The first written description of the disease is credited to Albert Ruskin Cook in 1897 at Mengo Hospital in Uganda. Fifty years later, the causative bacterium was isolated and identified by a group at the The Alfred Hospital in Melbourne.
What kind of disease is Buruli ulcer?
It was Buruli ulcer: a bacterial disease that can cause large open wounds and, if untreated, lead to permanent disfigurement. It was about six weeks from Noel noticing the mark to getting a definitive biopsy and taking the right medication.
Why did Noel go to hospital for Buruli ulcer?
So back to hospital he went, this time to St Vincent’s, one of Australia’s leading hospitals. They kept him in for about a week taking biopsies before finally confirming the cause of Noel’s ordeal.
