Wool-sorter's disease is caused by which organism?

Wool-sorter’s disease is caused by Listeria monocytogenes, a Gram-positive rod that can live inside cells (facultative intracellular). This organism is classically linked to listeriosis, and the name wool-sorter’s disease comes from outbreaks among workers handling wool who inhaled contaminated dust, leading to septicemia and meningitis in susceptible adults. Listeria is notable for its ability to grow at refrigerator temperatures and its tendency to invade the bloodstream and central nervous system, which explains the severe systemic infections seen in at-risk groups. The other organisms listed are responsible for many common infections, but they are not associated with this historical name. E. coli is a frequent cause of urinary and gastrointestinal infections; Staphylococcus aureus causes skin, soft tissue, and other infections; Bacillus cereus is known for its food poisoning.
