| meningitis due to xanthomonas maltophilia: case report and review. | xanthomonas maltophilia is being increasingly recognized as an opportunistic pathogen in debilitated patients. we report a case of postoperative meningitis due to x. maltophilia and review the cases of x. maltophilia meningitis reported in the literature. because x. maltophilia is often resistant to multiple beta-lactam agents, including cephalosporins and imipenem, trimethoprim-sulfamethoxazole appears to be the drug of choice for treatment of x. maltophilia meningitis. | 1994 | 7986908 |
| the antibiotic susceptibilities of xanthomonas maltophilia and their relation to clinical management. | an increase in recovery of xanthomonas maltophilia from clinical specimens at our institutions prompted, amongst other measures, an investigation of the antibiotic susceptibility patterns of the organism. fifty-five consecutive first isolates of xanthomonas maltophilia were obtained and antimicrobial susceptibility tests were carried out by the agar dilution method. trimethoprim/sulfamethoxazole was the most active antimicrobial agent (94% susceptible), with 71% susceptible to ticarcillin/clavul ... | 1994 | 7991292 |
| bacterial colonisation with xanthomonas maltophilia--a retrospective study in a cystic fibrosis patient population. | xanthomonas maltophilia was isolated from 25 of 150 patients with cystic fibrosis during a period of 10 years (1983-1992). twelve patients harboured x. maltophilia chronically, i.e. repeatedly for more than 6 months. no predisposing factors for the colonisation could be identified by studying the clinical and laboratory data of the patients, including preceding and concurrent bacterial colonisation with other bacteria, antibacterial treatments, pulmonary function and biochemical markers. up to 2 ... | 1994 | 8002085 |
| the bacteriology of obstructive pneumonitis. a prospective study using ultrasound-guided transthoracic needle aspiration. | obstructive pneumonitis, the opacity that develops distal to an obstructing endobronchial lesion or external compression, is actually a combination of atelectasis, bronchiectasis with mucus plugging, and true parenchymal inflammation. in the majority of cases, it is usually not possible to determine whether infection is present or not from the radiographic findings alone. the aim of this study was to evaluate the bacteriology of obstructive pneumonitis and the influence of this result on the tre ... | 1994 | 8004324 |
| [a new threat: xanthomonas maltophilia infection. apropos of 50 cases]. | in an attempt to further characterize infections due to xanthomonas maltophilia (xm), we reviewed 50 case reports observed in our institution. xm is emerging as an important nosocomial pathogen in immunocompromised patients, especially those receiving broad spectrum antimicrobial antibiotherapy. distinction between colonisation and infection is often difficult. xm presents a therapeutic challenge because of its tendency to exhibit multiple resistance. | 1993 | 8009079 |
