Background: Like other countries in the world, Vietnam has seen the appearance of many infectious diseases such as SARS, influenza A/H1N1. Therefore, monitoring and quick response to infectious diseases, increasingly require enhancing the capacity of test systems. \r\n', u'Objectives: To determine the capacity for microbiological diagnosis and etiology of communicable diseases at the provincial centers for preventive medicine.\r\n', u'Subjects and methods: With the application of the cross-sectional approach, the study was conducted on microbiology diagnostic capacity for communicable diseases surveillance and response system in 55 Provincial Preventive Medicine Centers (PPMCs)\r\n', u'Results: Laboratory testing and confirmation (isolation and bio-chemical tests, gram stain) are only available for common nitrobacteria such as Escherichia coli, Vibrio cholera, Shigella, Salmonella, and some of the respiratory bacteria as streptococcus, meningococcus, etc... in most PPMCs. ELISA/MACELISA technique for detecting virus pathogen such as Arbo viruses (Dengue, Japanese B encephalitis) and Hepatitis B, HIV is also a focus of these PPMCs. However, for diseases caused by other viruses like Polio, Rota, measles, influenza, PPMCs have only the ability to collect specimens. \r\n', u'Conclusions: Most of the cases reported in the surveillance reports are based on clinical signs, only. Case confirmation was done by hospital/regional or national laboratory. \r\n', u'\r\n', u'

BACKGROUND/AIMS: The aim of this study was to evaluate the peritonitis-causing bacteria detected in peritoneal fluid using a blood culture bottle in patients undergoing continuous ambulatory peritoneal dialysis (CAPD). METHODS: One-hundred and eleven dialysates from 43 patients suspected of peritonitis related to CAPD were retrospectively evaluated between May 2000 and February 2008. In all cases, 5 to 10 mL of dialysate was inoculated into a pair of BacT/Alert blood culture bottles, and 50 mL of centrifuged dialysate was simultaneously inoculated into a solid culture media for conventional culture. The results were compared to those of the conventional culture method. Isolated microorganisms were compared between the two methods. RESULTS: The blood culture method was positive in 78.6% (88 / 112) of dialysate specimens and the conventional culture method in 50% (56 / 112, p < 0.001). CONCLUSIONS: The blood culture method using the BacT/Alert system is useful for culturing dialysates and improves the positive culture rate in patients with suspected peritonitis compared to the conventional culture method.
