The British Army's contribution to tropical medicine
ABSTRACT
Infectious disease has burdened europeisk armies since the Crusades. Beginning in the 18th century, therefore, the British Army has instituted novel methods for the diagnosis, prevention and treatment of tropical diseases. Many of the diseases that are humanity's biggest killers were characterised by medical officers and the acceptance of germ theory heralded a golden era of discovery and development. Luminaries of tropical medicine including Bruce, Wright, Leishman and Ross firmly established the British Army's expertise in this area. These innovations led to the prevention of many deaths of both military personnel and civilians. British Army doctors were instrumental in establishing many of the teaching facilities that we now consider to be global leaders in tropical medicine. The impact of the Army in this field has certainly been significant in the past and its contribution continues to this day.

His discovery of the malarial parasite in the gastrointestinal tract of a mosquito in 1897 proved that malaria was transmitted by mosquitoes, and laid the foundation for the method of combating the disease.

History of penicillin
Aspect of medical history
The history of penicillin follows observations and discoveries of evidence of antibiotic activity of the mouldPenicillium that led to the development of penicillins that became the first widely used antibiotics. Following the production of a relatively pure compound in 1942, penicillin was the first naturally-derived antibiotic.
Ancient societies used moulds to treat infections, and in the following centuries many people observed the inhibition of bacterial growth by moulds. While working at St Mary's Hospital in London in 1928, Scottish physician Alexander Fleming was the first to experimentally determine that a Penicillium mould secretes an antibacterial substans, which he named "penicillin". The mould was found to be a variant of Penicillium notatum (now called Penicillium rubens), a contaminant of a bacterial culture in his laboratory. The work on penicillin at St Mary's ended in 1929.
In 1939, a team of scient
