Madurella mycetomatis is a fungus primarily reported in Central Africa as a cause of mycetoma in humans. It has been misclassified for many years, but with improvement of molecular techniques, its phylogenetic classification has been established.

Many methods exist to identify M.

Mycetoma caused by Madurella mycetomatis: a completely neglected medico-social dilemma.

Histological examination is especially useful, as it has many unique morphological features. Strain-level differences in response to antifungal agents is informative for treatment and laboratory isolation of cultures. Madurella mycetomatis underwent many name changes.

InBrumpt described the first recorded case of mycosis caused by M. InBrumpt corrected its genus to Madurellain turn changing its name to Madurella mycetomi.

Mycetoma caused by Madurella mycetomatis: a completely neglected medico-social dilemma.

This error was eventually [ when? The genus Madurella contains only two well defined species: Roughly a dozen other species madurela uncertain validity have been described as genus Madurella based on in vivo similarities and cultural sterility.

Myceomatis similar, there were important physiological and morphological differences between the two well defined species, leading scientists to doubt their phylogeny. The development of ribosomal sequencing and other molecular techniques, led to the discovery that M.

Genotypic variation can help explain geographical distribution of fungi and differences in host symptoms. This showed that M. The fungus’s ability, an inability, to break down various molecules can also be used to confirm its identity. Madurella mycetomatis is amylolytic yet is only weakly proteolytic, and has the ability to assimilate glucose, galactose, lactose and maltose, while unable to assimilate sucrose.

The melanin produced by the fungus has also been identified as a defense mechanism against processes such as hydrolytic enzymes, free radicals, redox buffering, antibodies and complement. The growth of M.

Initially the colony is dome shaped white-yellow or olivaceous brown in color. In nutritionally deficient or potato-carrot media, black grains 0. The grains are oval and often multi-lobed.

They are reddish brown to black in color and texturally smooth or ridged. The most common type is compact or filamentous, where a dark brown cement like amorphous, electron rich substance fills the voids surrounding the hyphal network. When stained with hematoxylin and eosin it appears rust-brown in color. Lesions can have both the filamentous and vesicular type grains at the same time. Although conidationa form of asexual reproduction, in M.

The conidia have truncated bases and are on the tips of simple or branched conidiophores. Madurella mycetomatis is the most common fungus with respect to causing mycetoma in humans, [14] a chronic localized inflammatory disease. Thus having identified M. There are various methods available for the purpose of differentiating fungal species.

Histological examination allows for the exploitation of unique morphological features of M. The highly variable nature of the ITS sequence between species not only allows for diagnosis, but also the identification of M.

ITS has also been cited as the recommended method for isolation of M. Understanding how a fungus might react to various anti-fungal agents in-vitro can be beneficial when wanting to study or isolate particular organisms in culture. When following these methods for M.
