Otto Bollinger

Otto Bollinger (1843-1909) was a German pathologist from Munich. He was a professor of general pathology and pathological anatomy at the institute of pathology in Munich.

In 1891 Bollinger provided an early description of a delayed traumatic apoplexy he called traumatische Spät-Apoplexie. Today this condition is called delayed traumatic intracerebral hematoma or (DTICH). His research was based on four patients who suffered a head injury, in which death occurred days to weeks later from an apoplectic event.

Bollinger had an extensive background in veterinary medicine, and was known for his studies of rabies and hydrophobia in the days before the discovery of an anti-rabies vaccine. In 1877 he described the etiologic agent of bovine actinomycosis ("lumpy jaw"), which he called actinomyces bovis.

Bollinger is credited with describing the inclusion bodies found in tissue cells in fowlpox. These bodies contain the fowlpox virus, and are now referred to as Bollinger bodies. Another eponymous term named after him are Bollinger granules, which are small yellowish-white granules that cluster, contain micrococci, and are seen in the granulation tissue of botryomycosis.
