چکیده
For more information on CIDM Public Health news and events, please visit our website.... Sporotrichosis is a dermatomycosis caused by the fungus, Sporothrix schenckii. It was first described by B.R.Schenck in the Bulletin of the Johns Hopkins Hospital in 1898. [1] Subsequently, Hektoen and Perkins named this pathogenic fungus Sporothrix schenckii in 1900. [1] Infection usually presents as ulcerative skin lesions, typically on the arms or legs, arising from a site of inoculation of the fungus, usually from plant material. The lesions spread in a linear fashion along lymphatic chains, an appearance hence known as ‘sporotrichoid spread’. Although the infection is readily treatable with oral antifungal agents, the diagnosis is often delayed, after antibiotics have been inappropriately prescribed. The infection is also known to relapse. Sporotrichosis occurs in geographical clusters, in warm moist climates such as in Queensland, Western Australia and northern NSW but, since it is not notifiable, the true incidence in Australia is unknown.

His hypothesis that cholera was spread by contaminated water was tested by the 'Broad Street' epidemic of 1854. Snow quickly traced the water used in the houses affected by cho...
