1/27. Isolation of pantoea agglomerans in two cases of septic monoarthritis after plant thorn and wood sliver injuries.arthritis after plant injury is often apparently aseptic. We report two cases due to pantoea agglomerans. In one case, the bacterium was isolated only from the pediatric blood culture media, BACTEC Peds Plus, monitored in BACTEC 9240, and not from the other media inoculated with the joint fluid. This procedure could help improve the diagnosis of septic arthritis.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
2/27. Identification by 16S ribosomal rna gene sequencing of an enterobacteriaceae species from a bone marrow transplant recipient.AIMS: To ascertain the clinical relevance of a strain of enterobacteriaceae isolated from the stool of a bone marrow transplant recipient with diarrhoea. The isolate could not be identified to the genus level by conventional phenotypic methods and required 16S ribosomal rna (rRNA) gene sequencing for full identification. methods: The isolate was investigated phenotypically by standard biochemical methods using conventional biochemical tests and two commercially available systems, the Vitek (GNI ) and API (20E) systems. Genotypically, the 16S bacterial rRNA gene was amplified by the polymerase chain reaction (PCR) and sequenced. The sequence of the PCR product was compared with known 16S rRNA gene sequences in the GenBank database by multiple sequence alignment. RESULTS: Conventional biochemical tests did not reveal a pattern resembling any known member of the enterobacteriaceae family. The isolate was identified as salmonella arizonae (73%) and escherichia coli (76%) by the Vitek (GNI ) and API (20E) systems, respectively. 16S rRNA sequencing showed that there was only one base difference between the isolate and E coli K-12, but 48 and 47 base differences between the isolate and S typhimurium (NCTC 8391) and S typhi (St111), respectively, showing that it was an E coli strain. The patient did not require any specific treatment and the diarrhoea subsided spontaneously. CONCLUSIONS: 16S rRNA gene sequencing was useful in ascertaining the clinical relevance of the strain of enterobacteriaceae isolated from the stool of the bone marrow transplant recipient with diarrhoea.- - - - - - - - - - ranking = 1.2keywords = plant (Clic here for more details about this article) |
3/27. The fate of cadaver renal allografts contaminated before transplantation.Through the routine use of cultures from saline slush transport solution and the initial and final organ perfusates, 14 of 81 cadaver allografts (17.3%) were found to have been contaminated before transplantation. Gram negative organisms, cultured from 5 of the 14 contaminated allografts, resulted in the recipient's death on the first encounter with this problem and the loss of two other allografts. Early antibiotic therapy begun even without evidence of overt infection appeared to prevent any further deaths or graft loss in those whose allografts were contaminated and yielded an overall survival comparable to that of uncontaminated allografts. Without such an approach to the study of perfused cadaver allografts and the management of them when found to be contaminated, this type of infection may go undetected and contribute to allograft and patient loss.- - - - - - - - - - ranking = 1keywords = plant (Clic here for more details about this article) |
4/27. Delayed-onset postoperative endophthalmitis caused by hafnia alvei.PURPOSE: To identify hafnia alvei as an etiological factor of delayed-onset endophthalmitis. CASE REPORT: A 68-year-old woman had uneventful cataract extraction by phacoemulsification with foldable posterior chamber intraocular lens implantation under topical anesthesia in the left eye. Four weeks later, the patient presented anterior uveitis treated by topical corticosteroids. Seven weeks later a posterior uveitis with retinal vasculitis appeared. The patient was treated by systemic and intravitreal corticosteroids without result. Due to the poor course pars plana vitrectomy was done, and a vitreous sample was taken. Microbiologic examination disclosed hafnia alvei, gram-negative bacteria rarely isolated from human specimens. CONCLUSIONS: hafnia alvei should be considered in the etiology of delayed-onset endophthalmitis.- - - - - - - - - - ranking = 0.2keywords = plant (Clic here for more details about this article) |
5/27. Nationwide epidemic of septicemia caused by contaminated intravenous products. I. Epidemiologic and clinical features.Between mid-1970 and April 1, 1971, enterobacter cloacae or E. agglomerans septicemia developed in 378 patients in 25 American hospitals while they were receiving intravenous products manufactured by one company. Each of the hospitals noted a marked increase in the incidence of such septicemia during this period. Enterobacter agglomerans (formerly designated erwinia, herbicola-lathyri group) was better known as a plant pathogen and had been a human blood pathogen only rarely in the past. Septicemia caused by E. cloacae had also been uncommon.- - - - - - - - - - ranking = 0.2keywords = plant (Clic here for more details about this article) |
6/27. sepsis in a renal transplant recipient due to Citrobacter braakii.cellulitis is usually caused by organisms such as beta-hemolytic streptococci and staphylococcus aureus. Citrobacter are gram-negative bacilli that can cause opportunistic infections in immunocompromised hosts. They are rarely implicated in skin or soft tissue infections. The genus Citrobacter has been respeciated according to genetic relatedness. Citrobacter braakii refers to the genomospecies 6 of the citrobacter freundii complex. There are no detailed studies of infections caused by the newly formed specific genetic species. We report a case of C. braakii infection in a renal transplant patient receiving immunosuppressive therapy. The patient's lower extremity cellulitis did not respond to conventional antibiotic therapy. blood cultures grew C. braakii. Sensitivity studies and treatment with appropriate antibiotics resulted in prompt recovery. Immunosuppressive therapy in renal transplant recipients predisposes to infection by unusual pathogens, and this should be suspected when lack of a clinical response to conventional antibiotics is observed. We believe this is the first reported case of C. braakii cellulitis and bacteremia in a renal transplant recipient.- - - - - - - - - - ranking = 1.4keywords = plant (Clic here for more details about this article) |
7/27. urinary tract infection due to rahnella aquatilis in a renal transplant patient.rahnella aquatilis is an unusual gram-negative rod belonging to the family enterobacteriaceae. It inhabits fresh water and is rarely isolated from clinical specimens.

8/27. meningitis due to enterobacter aerogenes subsequent to resection of acoustic neuroma and percutaneous endoscopic gastrostomy tube placement: a rare nosocomial event.We present a case of meningitis after percutaneous endoscopic gastrostomy (PEG) tube placement subsequent to acoustic neuroma resection and cranioplasty. Four days following PEG tube placement, the patient developed enterobacter aerogenes meningitis, requiring explantation of infected cranioplasty material. His condition subsequently improved. Etiology and future intervention strategies are discussed.- - - - - - - - - - ranking = 0.2keywords = plant (Clic here for more details about this article) |
9/27. gas gangrene: an unusual cause of graft failure in an orthotopic pediatric liver transplant.gas gangrene of the liver is a very unusual cause of graft failure, and gas gangrene caused by enterobacter cloacae is also exceedingly rare. Although Clostridial infection could not be excluded in this case, the literature and our case show that enterobacter cloacae can be present in gas gangrene tissue whether or not it is the only infecting organism.- - - - - - - - - - ranking = 0.8keywords = plant (Clic here for more details about this article) |
10/27. epididymitis after prostate brachytherapy.OBJECTIVES: To analyze the incidence, time-course, and potential predisposing factors for what was clinically diagnosed as postimplant epididymitis. methods: Of 517 patients randomized and treated on two treatment protocols, with a planned total accrual of 1200, 5 patients were identified who developed clinically diagnosed epididymitis after iodine-125 or pallidium-103 prostate brachytherapy. Implants were performed by standard techniques, using a modified peripheral loading pattern. Perioperative antibiotics (cefazolin and ciprofloxacin) were given to 258 patients, according to physician preference. Treatment-related morbidity was monitored by mailed questionnaires, using standard American Urological association (AUA) and radiation Therapy Oncology Group criteria at 1, 3, 6, 12, and 24 months. patients who did not respond to the mailed questionnaires were interviewed by telephone. Although the patients were not queried specifically regarding epididymitis, its occurrence was noted when discovered in the course of follow-up examinations. RESULTS: Postimplant epididymitis occurred in 5 (1%) of 517 consecutive brachytherapy patients. None of the 5 patients had had a prior history of orchitis, epididymitis, vasectomy, or preimplant catheterization. The symptoms of epididymitis first appeared at 4, 7, 10, 150, and 300 days after implantation. patients with epididymitis had prostate volumes, preimplant AUA scores, and ages typical of other implant patients. No association was apparent between postimplant epididymitis and the degree of implant-related prostate swelling or the number of seeds implanted. Only the preimplant AUA score predicted for epididymitis, but 2 of the 5 patients had low scores. Only 1 (0.4%) of the 258 patients who received perioperative antibiotics developed epididymitis, and 4 (1.5%) of the 259 patients with prophylactic antibiotics developed epididymitis. CONCLUSIONS: epididymitis is an uncommon postimplant complication occurring in 1% of a large patient cohort. That epididymitis patients had greater preimplant AUA scores is consistent with a retrograde infection route, at least in some cases.- - - - - - - - - - ranking = 2.6keywords = plant (Clic here for more details about this article) |
