Postoperative endophthalmitis caused by Sphingomonas paucimobilis.
ABSTRACT We present a case in which a new organism, Sphingomonas paucimobilis, caused endophthalmitis after phacoemulsification in a 73-year-old woman. The case shows a recurrent acute endophthalmitis with complete resolution only after vitrectomy. This organism has not been described as a cause of endophthalmitis and was resistant to initial medical management. We also describe an interaction between this organism and a co-infective organism that may account for the unusual clinical course.

ABSTRACT: The characterization and therapeutic management of a case of postsurgery bacterial endophthalmitis caused by Shingomonas paucimobilis was presented. Endophthalmitis is the inflammation of the intraocular tissues and considered as the most devastating postoperative complication. The visual prognosis of this disease is very reserved judgement and high risk of sequelae. Sphingomonas paucimobilis are bacillus-shaped, chemoheterotrophic and strictly aerobic Gramnegative bacteria that cause diseases in the human being, mainly nosocomial infections that are typically treated with antibiotics. Based on its biodegrading and biosynthetic capacities, there are few reports on intraocular infections caused by this germ. The visual prognosis is favourable when the disease is early diagnosed and adequately managed. A case of endophthalmitis following a cataract surgery and caused by Shingomonas paucimobilis in Cuba in September 2009 was presented in this article.

ABSTRACT: We describe a very rare case of chronic peritonitis with secondary adhesive intestinal obstruction caused by Sphingomonas paucimobilis in a healthy 28-year-old Chinese man. This bacillus has not been described as a cause of spontaneous peritonitis in healthy people. It was an asymptomatic, generalized, and slow-growing peritonitis causing peritoneal adherens and at the end intestinal occlusion that needed surgical adhesiolysis.Clinical Journal of Gastroenterology 06/2009; 2(3):178-182.

ABSTRACT: The microbial biodiversity of bioaerosols in recently occupied hospital rooms was assessed in a pulmonology unit. Environmental samples and isolates were also screened for antibiotics resistance genes. Biofilms from sink drains were also studied to evaluate whether sink drains constitute a potential source of bioaerosols in this environment and a reservoir for opportunistic bacteria and antibiotic resistance genes. Stenotrophomonas maltophilia was by far the most frequently isolated microorganisms from the biofilm, followed by Enterobacter cloacae. Airborne bacterial concentration ranged from 14 to 74CFUm−3 and fungi ranged from 50 to 600CFUm−3. Biofilm bacteria were outnumbered in aerosols by microorganisms affiliated with human skin flora. Nonetheless, they were recovered from air samples in low concentrations. Erythromycin resistance genes were detected in all air samples collected from hospital rooms, and tetracycline resistance genes were detected sporadically. Antibiotic resistance genes were found in a single drain suggesting that genes present in DNA extracts from air samples were not aerosolized from sink drains, but rather from an unknown source. Results obtained in this study suggest that bacteria from sink drains were not aerosolized in significant concentration. They still remain a concern because of the risk of aerial transmission associated with their presence.
