Climate and landscape factors associated with Buruli ulcer incidence in Victoria, Australia.

Background: Buruli ulcer (BU), caused by Mycobacterium ulcerans (M. ulcerans), is a necrotizing skin disease found in more than 30 countries worldwide. BU incidence is highest in West Africa; however, cases have substantially increased in coastal regions of southern Australia over the past 30 years.

Charles Darwin's impressions of New Zealand and Australia, and insights into his illness and his developing ideas on evolution.

Charles Darwin visited New Zealand in December 1835, and Australia from January until March 1836, on the return portion of his voyage around the world in HMS Beagle. Despite the shortness of these visits, he retained an interest in these countries throughout his life, maintaining correspondence and receiving many biological specimens. His experiences in these places influenced his thinking on evolution, particularly on the evolution of man.

Localised Mycobacterium ulcerans infection in a cat in Australia.

A 10-year-old castrated male domestic cat domiciled in eastern Victoria (Australia) was presented for a subcutaneous mass on its nasal bridge in November 2006. Cytological examination of an aspirate demonstrated pyogranulomatous inflammation. At surgery, the lesion consisted of an encapsulated mass containing viscid fluid.

Mycobacterium ulcerans in mosquitoes captured during outbreak of Buruli ulcer, southeastern Australia.

Buruli ulcer (BU) occurs in >30 countries. The causative organism, Mycobacterium ulcerans, is acquired from the environment, but the exact mode of transmission is unknown. We investigated an outbreak of BU in a small coastal town in southeastern Australia and screened by PCR mosquitoes caught there.

Consensus recommendations for the diagnosis, treatment and control of Mycobacterium ulcerans infection (Bairnsdale or Buruli ulcer) in Victoria, Australia.

Mycobacterium ulcerans causes slowly progressive, destructive skin and soft tissue infections, known as Bairnsdale or Buruli ulcer (BU). Forty-six delegates with experience in the management of BU attended a 1-day conference in Melbourne on 10 February 2006, with the aim of developing a consensus approach to the diagnosis, treatment and control of BU. An initial draft document was extended and improved during a facilitated round table discussion.

First case of Mycobacterium ulcerans disease (Bairnsdale or Buruli ulcer) acquired in New South Wales.

Mycobacterium ulcerans is a slow-growing environmental bacterium that causes Buruli ulcer (also known as Bairnsdale ulcer in Victoria and Daintree ulcer in northern Queensland). We describe two patients with laboratory-confirmed Buruli ulcer who were infected either in New South Wales or overseas. A molecular epidemiological investigation demonstrated that, while one case was probably acquired in Papua New Guinea, the other was most likely to have been acquired in southern NSW.
