“…This case demonstrates a delayed onset of postoperative endophthalmitis at 3 months after cataract extraction and posterior chamber intraocular lens implantation 1. Another case report was the 50-year-old male with end-stage renal disease who had been receiving continuous ambulatory peritoneal dialysis for peritonitis from Kocaeli, Turkey.…”

Sphingomonas paucimobilis, is a yellow-pigmented, aerobic, non fermentative, gram negative motile bacillus. S. paucimobilis which is widely found in nature and hospital environments rarely cause serious or life threatening infections. In this report, a case of hospital acquired bloodstream infection due to S. paucimobilis in a patient with Down syndrome who was on treatment for presumed pneumonia is presented.A one year-old child patient who was a known case of Down syndrome and had previously experienced cardiac surgery was hospitalized and treated for pneumonia. On the 12th day of hospitalization, blood cultures were taken because of a high body temperature. One of the blood cultures was positive for gram-negative rods. After 48 hour of incubation, the sub-cultures on blood agar medium yielded pure growth of a yellow, non-fermentative, gram-negative, rod-shaped bacterium. The microorganism was positive for oxidase, and esculin hydrolysis, while negative for urea and nitrate reduction, citrate utilisation and motility. The isolate had been identified as S. paucimobilis by using Vitek 2 system. The antibiotic susceptibility test was also performed with the same system and the strain was found to be susceptible to piperacillin-tazobactam and other antibiotics. Treatment with intravenous piperacilin-tazobactam (150 mg/kg/day) was initiated. He responded well to the treatment and was discharged after 10 days. This case is reported to emphasize that S. paucimobilis should be kept in mind as a nosocomial infectious agent in patients with Down syndrome and immunosuppressive patients and the infections should be treated according to the sensitivity test results.

A rare case of peripartum endogenous bacterial endophthalmitis

We describe the case of a healthy, pregnant female who developed endogenous endophthalmitis at the time of delivery, and discuss the possible mechanism of infection and the management of this case. A 26-year-old Asian woman presented with a 3-week history of visual deterioration and pain in the right eye. There was no history of ocular trauma or surgery. The ocular symptoms developed one day after vaginal delivery of a healthy baby. The pregnancy had been uncomplicated until premature rupture of membranes one week prior to delivery. Right visual acuity was light perception. There was marked right anterior chamber activity with a hypopyon and fibrin. A B-scan ultrasound showed dense vitritis. Examination of the left eye was normal. Blood tests and a chest X-ray were normal. A vitreous tap was performed and bacterial culture grew Sphingomonas paucimobilis. Intravitreal antibiotics were injected (amikacin 0.4 mg/0.1 ml and vancomycin 2.0 mg/0.1 ml) and the patient was treated with oral moxifloxacin and corticosteroids. Right visual acuity improved to 6/9. This case highlights the need for clinicians to have a high level of awareness of endogenous bacterial endophthalmitis (a rare, potentially sight-threatening condition) in any patient with a painful eye or visual deterioration in the peripartum period, particularly if associated with complications such as premature rupture of membranes or perineal laceration.

“…Several species of the family Enterobacteriaceae have been identified in endophthalmitis and conjunctivitis [11,12]. A case of postoperative endophthalmitis caused by Sphingomonas paucimobilis has been reported [13] as has an infection with H. influenzae associated with use of contact lenses [14]. A case of keratitis has been attributed to Chryseobacterium meningosepticum [15].…”

DNA sequence-based identification of pathogens from ocular samples of patients with clinically suspected eye infections was accomplished using 16S and internal transcribed spacer (ITS) ribosomal RNA gene sequence analysis. PCR was positive for 24 of 99 samples tested. Both culture and 16S rDNA sequence analysis identified Pseudomonas aeruginosa, streptococci and Enterobacteriaceae. Isolates misidentified as Burkholderia cepacia by biochemical tests were identified as Ralstonia mannitolilytica by 16S rDNA sequence analysis. Sequence analysis identified the following microorganisms from 19 culture-negative samples: Haemophilus influenzae, Sphingomonas sp., Klebsiella pneumoniae, Staphylococcus haemolyticus, Morganella morganii, Mycobacterium sp., Chryseobacterium sp., Pseudomonas saccharophila (Xanthomonas) and the fungus, Phaeoacremonium inflatipes.
