Lucke (1862) first described that the bluish green discolouration of surgical dressing is associated with the presence of small vibrio like organisms. Gessard (1882) first isolated the bacteria as Pseudomonas.

Identification of the etiologic agent of glanders was performed in 1882 by isolating a bacterium from the infected liver and spleen of horse. Since its discovery, the pathogen has been classified as Loefflerella mallei, Pfeifferella mallei, Malleomyces mallei, Actinobacillus mallei, Corynebacterium mallei, Mycobacterium mallei, Pseudomonas mallei, and currently as Burkholdria mallei. The genus Burkholderia was created to accommodate former rRNA group II (Pseudomallei group) Pseudomonas bacteria. It was based on the 16S rRNA sequences, DNA-DNA homology values, cellular lipid and fatty acid composition.

History of rickettsial infections went back to 16^th century and it has long been associated with famine and war. Epidemic typhus had major impact to decide over the outcome of several wars. The epidemic alone killed or caused great sufferings to over 1,00,000 people during World Wars. However, the causative agent was not determined until the early part of the 20^th century. Rocky Mountain spotted fever (RMSF) was the first detected rickettsial infection in 1896 in Idaho Valley, USA. It was originally known as ‘black measles’ due to its clinical appearance in the form of characteristic spotted rash throughout the body. Howard Taylor Ricketts, an American pathologist for the first time described the causative agent of Rocky Mountain spotted fever and was able to isolate it in the laboratory animals during 1902-1909. He was a dedicated scientist and on several occasions injected himself with the pathogen for experiment. The causative pathogen of Rocky Mountain spotted fever, Rickettsia rickettsii was named after him. Later, the family Rickettsiaceae as well as the order Rickettsiales was named after him. Ernest William Goodpasture, an American pathologist and physician, invented the methods of isolation and culturing the rickettsial pathogens in chicken embryos and fertilized chicken eggs.
