Melioidosis is a long-known disease since 1912, but only quite recently we have obtained the knowledges about its actual clinical and epidemiological features. The disease is so unique in having a wide spectrum of disease course and clinical manifestation. The causative agent, P. pseudomallei, is free-living bacterium in the natural environments (soil and surface water) of tropical and subtropical areas. Just like legionnaires' disease, melioidosis is a good example of infectious disease in which pneumonia is produced by inhalation of contaminated soil dusts or water droplets. The infection becomes dormant for years, but with a chance of recrudescence under a variety of insults to the host resistance. The disease, may it be acute or chronic, will be symptomatically confused with malaria, typhoid fever, leptospirosis, septicemia caused by other gram-negative bacteria, tuberculosis and mycotic infections. Isolation of the causative agent from clinical specimens is the only reliable method for diagnosis. Because of the increasing clinical awareness and the development of diagnostic methods, the reported cases of melioidosis have numbered almost one thousand in Thailand during the past 20 years. This country has now the most ample clinical experiences on melioidosis. We have reviewed the history of melioidosis research from bacteriological, immunological, clinical and epidemiological viewpoints, especially including the recent reports in Thailand.

Melioidosis is endemic in Southeast Asia but reports of prostatic involvement are rare. We describe a patient with Pseudomonas pseudomallei septicemia and a prostatic abscess who presented with signs and symptoms of a urinary tract infection. The organism was cultured from the blood, urine and prostatic pus, and was treated successfully with co-trimoxazole and surgical drainage. Genitourinary infection with Pseudomonas pseudomallei should be considered in patients from endemic areas, and bacteriological investigation is essential for the diagnosis and management.

A case is reported of a fifty-seven year old man with fever, who was admitted to hospital after a recent visit to Southeast Asia. Among the clinical findings prostatitis and broncho-pneumonia were noted. Within twenty-four hours irreversible fulminant sepsis developed although he was treated with cefotaxime, tobramycin and erythromycin. Post mortem Pseudomonas pseudomallei was cultured from blood and aspirate collected by bronchoscopy. It is important to consider melioidosis as a cause of septic illness in patients who have been visiting Southeast Asia.

We report a case of Pseudomonas pseudomallei infection, in which the patient acquired the bacteria by aspiration of river water after a drowning incident near Manila, the Philippines. The pulmonary form of melioidosis was noted at the onset, but septicemia developed at a later stage. Positive blood cultures were obtained 17 days after the accident. The patient was treated successfully with a combination of amikacin and cephalothin. This is the first report of P. pseudomallei infection documented in Taiwan.

Pseudomonas pseudomallei is a causative agent of melioidosis. The disease manifestations range from fulminant sepsis to asymptomatic seroconversion. In septicemic cases, a mortality rate of 80-90% is reported. Rapid and specific diagnosis has become important to the clinical microbiology laboratory. We have developed a P. pseudomallei-specific DNA probe. The cloned fragment, herein designated pKKU-S23L, contained 1.5 kb of P. pseudomallei chromosomal DNA. A radioactively labelled pKKU-S23L insert could detect 1.5 ng of its genomic DNA or 40,000 P. pseudomallei cells. The probe was highly specific for P. pseudomallei DNA and did not cross-hybridize with DNAs prepared from other related bacteria. Using pKKU-S23L as a probe in total cellular DNA digestions and Southern blot hybridization, we were able to classify 60 P. pseudomallei clinical isolates obtained from individual melioidosis patients into eight categories. Therefore, this probe has a potential not only for use in development of specific detection of bacterial DNA in clinical specimens but also for application in epidemiological studies of P. pseudomallei.

Melioidosis was diagnosed in a diabetic sailor who presented with a history and chest radiograph that suggested tuberculosis. Melioidosis is a tropical disease with protean manifestations: from asymptomatic infection to chronic cavitary lung disease to overwhelming sepsis. The diagnosis is easily made, even in nonendemic areas when duly considered by the clinicians and microbiology laboratory. Ceftazidime has dramatically improved outcomes in hospitalized patients with severe melioidosis.

From 1975 to 1989, a total of 73 strains of P. pseudomallei was isolated from the water samples and the pathological samples of human and domestic animals in 13 counties and cities located different latitude from four provinces Qiong, Yue, Gui and Xiang in China. Serological investigation demonstrated that the geographical distribution of the organism had a significant correlation with the positive rate of antibodies against P. pseudomallei and the native foci of the organisms distributed over the southern subtropical zone and the edge of tropical zone in Qiong, Yue and Gui. In endemic areas, the positive rates of antibodies against P. pseudomallei in human-beings, horses, oxen and pigs are 3.8%-15.2%, 9.1%-18.4%, 6.6%-33.0% and 35% respectively. The investigation results showed the horses and mules infected by the organism would interfere with quarantine of the animals, meanwhile, the meat contaminated by the bacterium would endanger the public health. In Sept. and Oct. of 1989, three cases in Zhanjiang and Sanya of Hainan were reported, two cases died of acute melioidosis with septicemia, another case was the chronic leg ulcers. So, it was predicated that there could have some cases of melioidosis which were misdiagnosed or missed out.

A retrospective analysis was done in 81 patients with visceral abscess due to melioidosis treated at Khon Kaen Hospital, northeastern Thailand from 1985 to 1993. The clinical presentations were fever 100 per cent, abdominal pain 39 per cent, cough 34.8 per cent, abdominal tenderness 27.5 per cent and palpable mass 24.6 per cent. The laboratory findings were not diagnostic of the etiology. The abscesses were detected by ultrasonography in 97.25 per cent and computed tomography 2.25 per cent. The lesions were found in the spleen 72.8 per cent, liver 45.7 per cent, kidney 12.3 per cent and prostate gland 2.5 per cent. Seventy-six per cent of the patients had diseases in multiple organs (viscera, lungs and others). The preliminary diagnoses were fever of unknown origin, septicemia and urinary tract diseases in one-half of the cases. Patients presenting with fever of unknown origin from an endemic area, like northeastern Thailand, should arouse suspicion of melioidosis and search for the organism is advised. Diagnostic imaging methods, ultrasonography and computed tomography are valuable tools for detection of a solid internal organ abscess.

Pseudomonas pseudomallei is the causative agent of melioidosis, a disease being increasingly recognized as an important cause of morbidity and mortality in many regions of the world. An intriguing observation regarding melioidosis is that a significant percentage of patients who develop the disease have preexisting diabetes mellitus. In this regard, we have tested the hypothesis that insulin may modulate the growth of P. pseudomallei. We have demonstrated that insulin markedly inhibits the growth of P. pseudomallei in vitro and in vivo. The growth rate of P. pseudomallei in minimal medium containing human recombinant insulin was significantly lower than that of control cultures containing no insulin. P. pseudomallei grew at an increased rate in serum samples obtained from diabetic rats compared with that in serum samples obtained from control animals. When the insulin level was restored by the addition of human recombinant insulin, the growth rate was reduced to a level similar to that seen in control serum. P. pseudomallei also grew significantly better in insulin-depleted human serum than control human serum. 125I-insulin binding studies demonstrated that P. pseudomallei possesses a specific, high-affinity binding site for human insulin. In in vivo studies, rats made diabetic by streptozotocin injection (80 mg/kg of body weight, intraperitoneally) were significantly more susceptible to P. pseudomallei septicemia than control rats. Thus, it appears that serum insulin levels may play a significant role in modulating the pathogenesis of P. pseudomallei septicemic infections.

Fifty-five children with culture-proved melioidosis treated at Srinagarind Hospital from 1979 to 1993 were retrospectively reviewed. Twenty patients had septicemia and 35 patients had localized infection. Eleven patients (55%) in the septicemic group had underlying diseases but none in the localized infection group. In the septicemic patients the most common organ involvement was the lung (75%). Shock was present in 45% and the case fatality rate was very high (60%). In localized melioidosis suppurative parotitis was the most common manifestation (40%). Other common infections included skin and subcutaneous abscesses and lymphadenitis. There was no shock or death in this group.
