What are the differences between mucor and aspergillus structures?

Answer 1

According to Harrison 17th ed -

Mucor are generally seen as Broad Hyphae which are rarely septate and branch out at right angles on Methanamine or PAS stain of Tissue. This can cause a highly invasive infection in patients with immunocompromise Diabetese Mellitus and Iron overload(especially the ones Taking Desferroxamine). This infection has a hallmark of Vascular Invasion and Tissue Necrosis. Unless identified well in time it can cause destruction of Tissue at a rapid pace. Rhinocerebral Mucormycosis can present as Proptosis Blindness due to Optic Nerve Involvement Cavernous Sinus Thrombosis. Pulmonary Mucormycosis can present as severe necrotising Pneumonia. Gastric Mucormycosis can present as viscour perforation.

Whereas

Aspergillus are Narrow Septate Hyphae branching out at Acute Angles. The infection caused by this organisms are not as aggressive as Mucormycosis. It can cause Invasive Pulmonary Disease, Sinusitis as well as invasive sinusitis etc.
