A microorganism is linked to a widespread disease

He used carbolic-acid-soaked lint on eleven-year-old James Greenlees’s open leg fracture.

James Greenlees was the patient whose case became central to Lister’s early account of antiseptic surgery.

The dressing was designed to keep damaging microorganisms from multiplying in an open wound.

Greenlees’s recovery strengthened Lister’s later published argument, although a single case could not establish the method alone.

He told a Berlin scientific society that he had identified the bacterium responsible for TB.

Koch’s findings opened pathways to laboratory detection, although effective treatment took much longer.

The annual 24 March date commemorates Koch’s disclosure rather than the eradication of tuberculosis.

The nine-year-old boy received the first dose of a post-exposure rabies vaccination course after dog bites.

The boy’s case followed animal experiments; he did not develop rabies.

Rabies prophylaxis required a series of inoculations rather than a single injection on this date.
