During [[World War I]] (1914–18), the local government board's laboratory was assumed by the national government, namely UK government, and became the [[Ministry of Health (United Kingdom)|Ministry of Health]]'s Pathological Laboratory—where Griffith was medical officer.  UK government spent money sparingly on the laboratory, which remained very basic, though Griffith and his colleague, William M. Scott, "could do more with a kerosene tin and a primus stove than most men could do with a palace".<ref name=pmid4143929/>

Griffith was sent pneumococci samples taken from patients throughout the country, amassed a large number, and would type—in other words classify—each pneumococci sample to search patterns of pneumonia epidemiology, and Griffith experimented on mice for improved understanding of its pathology.<ref name=Lehrer>Lehrer S.

With outbreak of [[World War II]] (1939–45), the laboratory was expanded into the Emergency [[Public Health Laboratory Service]].
