neonatal melioidosis: a report of 5 cases.melioidosis, caused by pseudomonas pseudomallei, occurs in tropical areas and is diagnosed mostly in adults. in khon kaen, a province of northeast thailand, five cases of infantile melioidosis were managed at srinagarind hospital. the patient's specimens were submitted to microbiologic and serologic examination for p. pseudomallei demonstrated by indirect hemagglutination. possible modes of transmission such as environment, perinatal exposure and venereal transmission were investigated.19883174307
melioidosis with brain abscess.central nervous system involvement in melioidosis is rare. we describe a 48 year old woman who developed septicaemia and a brain abscess due to pseudomonas pseudomallei. since there is a continuing practical problem in bacteriological confirmation of the aetiological agent, diagnosis of melioidosis has to be made on clinical suspicion.19883174527
evaluation of four serological tests for the diagnosis of caprine melioidosis.a complement fixation (cf) test, 2 indirect haemagglutination (iha-a; iha-l) tests which differed in antigen preparation and technique, and a microtitre agglutination (ma) test were compared in the serodiagnosis of melioidosis in goats. one hundred and eighteen experimental serums and 3143 field serums from goats in endemic and non-endemic areas of north queensland were used in the evaluation. culture of samples for pseudomonas pseudomallei from 112 goats provided substantiating evidence of infe ...19883190597
resistance of pseudomonas pseudomallei to normal human serum bactericidal action.the effect of human normal serum (hns) on pseudomonas pseudomallei was determined. it is apparent from our data that the organism is resistant to the normal serum bactericidal mechanism. ancillary experiments to confirm this serum-resistant property of p. pseudomallei were done by examining the effects of growth phase conditions of the bacteria (i.e., logarithmic and stationary phases) and different buffered systems used as diluent in our bactericidal assay. results obtained showed similar degre ...19883193910
in vitro activities of the newer beta-lactam and quinolone antimicrobial agents against pseudomonas pseudomallei.imipenem was highly active and bactericidal against all 100 strains of pseudomonas pseudomallei tested, followed in activity by piperacillin, carumonam, ceftazidime, cefotaxime, and ceftriaxone. the addition of clavulanic acid significantly increased the activities of both amoxicillin and ticarcillin. ciprofloxacin and norfloxacin showed poor activity against test strains.19883196005
childhood melioidosis in northeastern thailand.eighteen cases of childhood melioidosis in northeastern thailand were reviewed. the mean age was 6.8 years with a range from eight months to 15 years. twelve cases (66.7%) had localized melioidosis, six of which had pneumonia. three patients were diagnosed as pharyngocervical melioidosis, the newly recognized syndrome. nine cases (50.0%) had associated diseases including dengue hemorrhagic fever (dhf) in five cases. in all five cases, melioidosis was diagnosed during the convalescent stage as a ...19883227408
characterization of monoclonal antibodies to protein antigen of salmonella typhi.two monoclonal antibodies were produced against protein antigens of salmonella typhi. one of the antibodies (stp14) belongs to the immunoglobulin g1k subclass, and the other (stp13) was assigned to the immunoglobulin g2a(kappa) subclass. both antibodies could recognize the 34.0-kilodalton protein antigen from s. typhi. the specificity of these antibodies was tested by immunoblotting with a panel of crude protein antigens from 12 bacteria causing enteric fever and enteric fever-like illness: s. t ...19883281976
clinical and pathological observations on goats experimentally infected with pseudomonas pseudomallei.the effects in goats of the subcutaneous injection of varying doses of pseudomonas pseudomallei (90 to 500,000 bacilli) suspended in normal saline are described. high doses (greater than or equal to 500 bacilli) caused acute, fatal infections. lower doses (90 to 225 bacilli) caused acute or chronic disease when infection became established. however, 11 of 18 goats injected with the lower doses of bacilli showed no sign of infection on clinical or bacteriological examination. response to antibiot ...19883355451
melioidosis: a reminder.recrudescent pulmonary melioidosis developed in two patients 12 and 16 years after their last travels to an endemic area. in one, a clinically silent prostatic abscess may have been the focus; and in both, the diagnosis was difficult to make even when the laboratory was notified of the possibility of infection with pseudomonas pseudomallei. recrudescent melioidosis should be considered in febrile patients who have been in endemic areas regardless of the interval from last exposure to the develop ...19883364451
[septic melioidosis following a visit to india].a case is reported of lethal septicemic melioidosis due to pseudomonas pseudomallei in a 40-year-old woman who had been in india. the epidemiology, clinical findings and management of this unusual disease are discussed. the diagnostic value of serological tests and in vitro sensitivity of pseudomonas pseudomallei to various antibiotics are outlined. melioidosis should be considered in the differential diagnosis of any febrile condition in a person returning from a tropical country.19883375792
[ecological and biological maintenance of sapronoses exemplified by melioidosis].the growth and death of pseudomonas pseudomallei, the causative agent of melioidosis, in the soil and the antigenic properties of this microorganism in the soil, in culture media, and in the body of animals have been studied. as revealed in this study, p. pseudomallei can grow in nonsterile soil substrates without the loss of virulence and changes in its antigenic structure. in the body of animals this microorganism rapidly adapts its virulence to host species by the transformation of its antige ...19883389005
activities of five new fluoroquinolones against pseudomonas pseudomallei.thirty-four isolates of pseudomonas pseudomallei were tested by a broth microdilution technique for susceptibility to amifloxacin, ciprofloxacin, enoxacin, norfloxacin, and ofloxacin. ciprofloxacin was the most active agent tested, with an mic for 90% of the strains tested of 8 micrograms/ml. these in vitro results suggest that the fluoroquinolones tested would not be optimal for therapy of melioidosis.19883415212
