CohortBoth qPCR assays were designed around the 28S rRNA gene in order to optimize the specificity of the assay. This was facilitated by the relative com- pleteness of the sequence data available on the 28S region of the rRNA gene complex.

Disease Introduction MechanismThe number of cases of zygomycosis have increased over the last six decades, making the diagnosis of these infections im- perative. Infections with Zygomycetes may advance rapidly, leading to fatality, particularly in patients with under- lying illnesses such as diabetes, bone marrow or solid-organ transplantation, and renal failure. The modes of transmis- sion are varied for the immunocompromised patient, but the inhalation of sporangiospores with subsequent pulmonary in- fection is the most common. A recent review reported an overall mortality of 76% for patients with pulmonary infec- tions due to Zygomycetes. Furthermore, in the immuno- compromised host, hematogenous dissemination is frequent and contributes to the high mortality rate, underscoring the urgency of making a rapid and accurate diagnosis of pulmo-nary zygomycosis.
