Pseudomonas stutzeri infection. A review of hospital isolates and a review of the literature.

Pseudomonas stutzeri is uncommonly isolated from patients and rarely causes disease. Clinical isolates of P. stutzeri from a university hospital were reviewed over a 16-year period. In the hospital review, only three patients were identified with P. stutzeri infection, and in only one of these was the organism present as the sole isolate. A review of the literature shows that P. stutzeri is most frequently isolated from blood, wounds, the respiratory tract, and urine. Patients with P. stutzeri infections often have serious underlying disease but generally respond to treatment with antibiotics including the aminoglycosides, the antipseudomonal penicillins, trimethoprim-sulfamethoxazole, and the third-generation cephalosporins.

Propionibacterium acnes osteomyelitis: case report and review of the literature.

Propionibacterium acnes, a part of the skin flora, caused vertebral osteomyelitis in a man who had recently undergone a microdiskectomy. The identifying characteristics and antibiotic susceptibility pattern are presented for this unusual human pathogen. The relationship of P. acnes to bone infection is summarized for the first time. A typical patient with P. acnes osteomyelitis is an adult male who has had prior surgery. Most patients respond favorably to prolonged antibiotic therapy.

Spontaneous bacterial peritonitis caused by Pasteurella ureae.

Pasteurella ureae is uncommonly isolated from patients and rarely causes disease. The case of a patient with spontaneous bacterial peritonitis caused by P. ureae is described and contrasted with other reported cases of P. ureae colonization and infection. Respiratory colonization has been described in older patients, predominantly men, with underlying lung disease consisting principally of bronchitis, bronchiectasis, and tumors. Only 11 patients (including the present patient) have been reported to have illness with P. ureae. Seven had meningitis, two had pneumonia, and one had hepatitis. Skull fracture, alcoholism, and liver disease are common antecedents of P. ureae infection.

Comparison of the API rapid E four-hour system with the API 20E overnight system for the identification of routine clinical isolates of the family Enterobacteriaceae.

Four hundred forty-one clinical isolates of the family Enterobacteriaceae were identified in parallel by using the API Rapid E 4-h and the API 20E overnight procedures (Analytab Products, Plainview, N.Y.). The results obtained by using the API Rapid E were compared with those obtained by using the API 20E. Discrepancies were resolved by using standard biochemicals. The API 20E identified 98.9% (436 of 441) of the isolates without the use of additional biochemicals and was found to be correct in each case of a discrepancy among the 436 isolates. The API Rapid E gave the same identification as the API 20E for 94.0% (410 of 436) of the isolates, misidentified 3.0% (13 of 436), and gave a correct but low-selectivity answer for the remaining 3.0% (13 of 436). The API Rapid E is a suitable alternative for the rapid identification of the Enterobacteriaceae.

Laboratory evaluation of the AutoMicrobic system for identification of Enterobacteriaceae.

The Enterobacteriaceae Biochemical Card used with the AutoMicrobic system (Vitek Systems, Inc., Hazelwood, Mo.) was compared with the API 20E system (Analytab Products, Plainview, N.Y.) for identifying members of the family Enterobacteriaceae. A total of 1,401 clinical isolates representing 18 species were identified by the AutoMicrobic and API 20E systems over a 5-month period. Discrepancies between these systems were resolved by conventional methods. Overall, 98.3% of the isolates were identified correctly by the AutoMicrobic system in 8 h, with 94.2% having an AutoMicrobic system confidence level greater than or equal to 90%; 92.9% of the isolates were identified correctly by the 20E system after 24 h of incubation. Discrepancies between the two systems occurred in 3.1% of the isolates. Of these, 40.9 and 59.1% proved to be correct by the AutoMicrobic and API 20E systems, respectively.

Media-dependent oxidase reaction in a strain of Aeromonas hydrophila.

A strain of Aeromonas hydrophila isolated from bile was oxidase positive only when grown on nonselective media. The isolate was oxidase negative when grown on gram-negative selective and/or differential media. It is proposed that oxidase tests on gram-negative rods be performed on colonies grown on nonselective media to assure valid results.
