It is unclear how imported melioidosis is able to persist in a completely new environment. Eventually, the outbreak terminated by itself after a period of time. It was only during the 1980s, Infectious Disease Association of Thailand started took notice of this disease. First conference on melioidosis was held in 1985 in Thailand. It was during this meeting that collaboration between Sappasitprasong Hospital, Thailand, and Wellcome-Mahido-Oxford Tropical Medicine Research Programme was established. Such collaboration made Thailand a world leader in clinical and epidemiology research on melioidosis.In 1989, several studies conducted in Thailand demonstrated ceftazidime as an effective antibiotic against melioidosis. Ceftazidime had been shown to reduce the risk of death of melioidosis from 74% to 37%. In 1990, a non-virulent arabinose-positive B. pseudomallei was found by Vanaporn Wuthiekanun. The organism was later reclassified into a new species called B. thailandensis. This species has become a useful tool in the laboratory for the studies of the pathogenesis of B. pseudomallei. B. pseudomallei was previously classified as part of the genus Pseudomonas. In 1992, the pathogen was formally named B. pseudomallei. In 1994, First International Symposium on melioidosis was held in Kuala Lumpur where 80 delegates attended. Papers were presented and later published as a book. Subsequent congresses were held in Thailand, Australia, and Singapore once every three years. In 2002, B. pseudomallei was classified as a "Category B agent". In 2004, the complete genome of B. pseudomallei was published.
Therefore, he named the new organism Bacillus pseudomallei. He did no further work on the organism. Arthur Conan Doyle may have read Whitmores report before writing a short story that involved the fictitious tropical disease "Tapanuli fever" in a Sherlock Holmes story titled "The Adventure of the Dying Detective" published in 1913. In the same year, melioidosis outbreak occurred inside the Institute for Medical Research (IMR), Kuala Lumpur, Malaya after its laboratory animals such as guinea pigs and rabbits were infected. William Fletcher and Ambrose Thomas Stanton, doctors who worked at the IMR, were the next ones to study the organism. They were unable identify the organism that caused the outbreak. It was only in 1917, when Fletcher isolated an organism similar to Whitmores bacillus from a Tamil rubber estate worker, the presence of the new species of bacteria was confirmed. The term "melioidosis" was first coined in 1921. The name melioidosis is derived from the Greek melis (μηλις) meaning "a distemper of asses" with the suffixes -oid meaning  "similar to" and -osis meaning "a condition", that is, a condition similar to glanders. B pseudomallei is similar in clinical presentation and genome make-up with B. mallei but is distinguished from it due to epidemiological and zoonotic characteristics.The first human case of melioidosis in South Asia was reported in Sri Lanka in 1927. In 1932, Thomas and Fletcher collected 83 cases of melioidosis from literature. In this case series, there were only two survivals. Since then, more case series of melioidosis were reported.
