Neonatal meliodosis: very rare but be aware.

Meliodosis is an infectious disease encountered mainly in tropics. It is not an uncommon problem in Malaysia especially in areas with agricultural activities. Although it can occur in all age groups, there have been few reported cases in children. Men are more commonly affected than women due to outdoor activities. Neonatal cases have been reported in Hawaii and Thailand. These infants presented with neonatal sepsis or meningitis. The mode of transmission to these infants has not been elucidated. This is the report of such a case first reported in Hospital Tengku Ampun Afzan, Kuantan.

[Properties of the Burkholderia pseudomallei insertional mutants deficient in membrane proteins production].

Transposon-induced B. pseudomallei mutants deficient in membrane proteins production were obtained for evaluation of the functional role of these cell components. In comparison with the wild type strain B. pseudomallei 57576, mutant clones TTM6, TTM7 and TTM9 carrying Tn5 chromosome insertions were characterized by lost or decreased production of outer membrane proteins 27, 48, 52, 150, 200 kDa. Alterations in outer membrane protein spectra were accompanied by twofold increase in susceptibility of bacteria to fluoroquinolones (pefloxacin, ofloxacin) and cephalosporins (ceftazidime) and noticeable reduction of virulence for white mice and guinea pigs in contrast to the initial strain, the obtained mutants were also less resistant in in vitro phagocyte killing.

Causes of fever in adults on the Thai-Myanmar border.

A hospital-based study was conducted along the Thai-Myanmar border to provide greater knowledge of the causes of febrile illness and to determine what zoonotic and vector-borne emerging infectious diseases might be present. A total of 613 adults were enrolled from June 1999 to March 2002. Cases were classified based on clinical findings and laboratory results. An etiologic diagnosis was made for 48% of subjects. Malaria was the most common diagnosis, accounting for 25% of subjects, with two-thirds Plasmodium falciparum. Serologic evidence for leptospirosis was found in 17% of subjects. Other etiologic diagnoses included rickettsial infections, dengue fever, and typhoid. The most frequent clinical diagnoses were nonspecific febrile illness, respiratory infections, and gastroenteritis. Clinical associations were generally not predictive of etiologic diagnosis. Apparent dual diagnoses were common, particularly for malaria and leptospirosis. Findings have been used to modify treatment of unspecified febrile illness in the area.

Lipopolysaccharide heterogeneity among Burkholderia pseudomallei from different geographic and clinical origins.

Heterogeneous patterns were obtained for lipopolysaccharide (LPS) from 1,327 Burkholderia pseudomallei isolates by sodium dodecyl sulfate-polyacrylamide gel electrophoresis, silver staining, and immunoblot analysis. Two LPS serotypes (A and B) possessing different ladder profiles and a rough LPS without ladder appearances were identified. All three LPS types were antigenically distinct by immunoblotting. The predominant type A (97%) produced the lowest amount of biofilm. The two less common types (smooth type B and rough type) were found more in clinical than environmental isolates and more in Australian isolates than Thai isolates. These isolates were more often associated with relapse than with primary infection.

Community-acquired pneumonia in adults at Srinagarind Hospital.

A prospective study of community-acquired pneumonia in adults at Srinagarind Hospital, Khon kaen University was conducted from September 1987 to August 1988. Laboratory specimens were tested for bacterial and mycoplasmal culture, CIE for pneumococcal antigen and serological data for mycoplasma and P. pseudomallei. The results supported by clinical data were evaluated. We could identify the pathogens from 62 of 113 cases (55%). P. pseudomallei was the most frequent etiologic agent (32%) and S. pneumoniae was the second (27%). Overall mortality was 21 per cent and it was high in cases with bacteremia and pneumonia due to P. pseudomallei. Sixty-six per cent of the patients had associated diseases. Diabetes mellitus, chronic renal failure and renal calculi were commonly found in patients with pneumonia due to P. pseudomallei. The results of this study showed the relatively high prevalence of P. pseudomallei pneumonia in our region which was different from other reports.

[Immunomodulating activity of RNA mononucleotides].

The immunological action of RNA mononucleotides was studied in animal experiments. The most pronounced activation of macrophagal glycolysis urea cycle, oxidative phosphorylation, lysosomal hydrolases was induced by uridine 5'-monophosphate (5'-UMP) and guanosine 5'-monophosphate (5'-GMP); 5'-GMP also induced the maximum increase of the expression of FC gamma receptors. 5'-UMP ensured cell activation comparable with the total action of all mononucleotides. 5'-UMP and 5'-GMP, used in combination, produced the highest stimulating effect on macrophages, and the addition of low-active adenosine 5'-monophosphate (5'-AMP) to active 5'-UMP did not decrease the stimulating potency of the latter. The stimulating activity of sodium nucleinate exceeded that of all mononucleotides and their combinations. 5'-GMP and 5'-AMP induced the maximum activation of oxygen metabolism, evaluated by chemiluminescence, while 5'-UMP and cytidine 5'-monophosphate (5'CMP) proved to be inactive. The shift of the phosphate group to the third carbon atom or the production of the oligonucleotide 5'-UMP consisting of 5-15 nucleotides resulted in the appearance of the capacity for stimulating oxygen metabolism in macrophages. Their in vitro cultivation with 5'-GMP and 5'-AMP induced the maximum increase of cell spreading in comparison with other mononucleotides, while the maximum increase of phagocytosis was ensured only by 5'-UMP and 5'-GMP.2+ 5'-UMP and 5'-GMP enhanced nonospecific resistance to Salmonella typhi infection, and sodium nucleinate, to Pseudomonas pseudomallei and Pseudomonas mallei infections.

Pseudomonas pseudomallei pneumonia with septicemia--case report.

A case of Pseudomonas pseudomallei pneumonia with septicemia is described. The onset was insidious with paucity of systemic symptoms except fever. Diabetes mellitus and alcoholism were associated problems. Initially blood cultures were negative but subsequently P. pseudomallei was isolated. The outcome was fatal. Unless diagnosed early and treated appropriately, patients often succumb to septicemic shock.
