Ralstonia pickettii is a low-virulence gram-negative bacillus that may be associated with infections related to health care and may cause bacteremia. Ralstonia pickettii bacteremia is uncommon but is related to the contamination of medical products, mainly in immunodepressed patients. We present two cases of patients on chronic hemodialysis with Ralstonia pickettii bacteremia linked to contamination of the dialysis water. Similar cases have been published with links to intravenous fluid administration, medication ampules, and the use of extracorporeal oxygenation membranes, among other factors. The detection of Ralstonia pickettii bacteremia should provoke suspicion and a search for contaminated medical products, fluids, and/or medications.

The weekly ILI morbidity and influenza positive samples in selected sites Conclusion: This active surveillance showed a certain existence of ILI morbidity and hospitalization especially among 0-4 age children, but there was no death observed during this period. In addition there were some cases of ILI seen while no influenza was detected. A multiple year study is necessary to figure out the disease burden of influenza and at the same time further study including etiological study is also necessary. At the moment, this community based information is useful to respond current pandemic (H1N1) 2009.
