Asthmatic Spores of Aspergillus Allergic Bronchopulmonary Aspergillosis Finger in Glove Sign Bronchiectasis and Inspissated Thick, tenacious mucus containing eosinophils, Charcot-Leyden crystals, cellular debris, and colonizing Aspergillus hyphae.

Artistic rendering shows an asthmatic man with breathing difficulty. The lungs are overlaid with Aspergillus spores, and a CT scan reveals the classic finger-in-glove sign at the left base. The gloved hand reinforces the concept of mucus-impacted bronchi in ABPA.

The Fungal Glove
A wheezing breath, a tightening chest,
The asthma patient finds little rest.
Within his airways, a shadow takes hold,
Not just of pollen, but of ancient mold.
Aspergillus spores, an innocent dust,
Ignite the deep tissues with allergic thrust.
The bronchi weep, they swell and they strain
Collecting thick mucus, a sticky, trapped rain.
The CT unveils what the dark lung concea
A tubular pattern, the truth it reveals.
It’s the Finger-in-Glove, a bizarre, branching sight
A bronchus distended, sealed up and white.
The hand of the fungus has grasped what it found,
A mold-laden mucus where air can’t be found.
A chilling reminder, dramatically made,
Of allergic defense in a life disobeyed
The glove is the airway, distended and weak,
The finger is sickness, a shape we must seek.
Etymology of Aspergillus

This image juxtaposes an ornate Christian liturgical implement, the Aspergillum, with the microscopic structure of the mold genus Aspergillus, explaining a remarkable moment of etymological crossover between biology and religion.
The Aspergillum (Latin for “little sprinkler,” derived from aspergere meaning “to sprinkle”) is the brush or perforated ball used by a priest to sprinkle holy water (the rite of Asperges).
The ubiquitous mold genus Aspergillus was named in 1729 by the Italian priest and biologist Pier Antonio Micheli. Viewing the asexual spore-forming structure (the conidial head) of the fungus under a microscope, Micheli was struck by its resemblance to the radiating bristles or perforations of the holy water sprinkler used in church ceremonies.
This dual image illustrates how the physical shape of a religious artifact provided the name for one of the most clinically important fungi, which causes a spectrum of human diseases collectively known as Aspergillosis.
