The local Chow Kit market is the largest wet market in the city of Kuala Lumpur. It is very close to the biggest government hospital in the city centre. However, the level of cleanliness in this area is always questionable and a matter of concern. The aim of this study was to identify the prevalence of T. gondii oocyst in water samples used by hawkers in that market and tissue cysts in rats’ brains captured from the same area. Water samples were taken to the parasitology laboratory at the National Universtiy of MalaysiaUniversity and a sugar flotation concentration method was used. Supernatant microscopical examination was then performed. A total of 752 slides were screened for the presence of T. gondii oocyst. A hundred rats wandering in the same area were also captured by the hawkers using mousetraps. After each animal was sacrificed, and an electric microtome was used to cut out serial sections 5μ thick from the rat brains. The de-waxed tissue sections were stained by the progressive Haematoxylin and Eosin (H&E) stain for microscopical examination. A total of 1000 slides were screened under a light microscope to detect the presence of T. gondii brain cysts. All the water samples were found to be negative for T. gondii oocyst. Out of the 100 rats captured, three rats were found to possess T. gondii cysts in their brains. Water samples reflect minimal or no solid food contamination, while the 3% of positive brain cysts influence the researchers to broaden their investigations for future projects., Amal R.

Cíl práce: Shrnout dosavadní výsledky získané v diagnostice toxoplazmózy pomocí metody polymerázová řetězová reakce na našem pracovišti. Materiál a metody: Byl vyšetřován různý biologický materiál od pacientů. K izolaci DNA byly použity dva komerční kity: QIAamp DNA Mini kit a QIAamp DNA Blood Mini kit (QIAGEN, Německo). Pro amplifi kaci byla vybrána oblast genu TGR1E. Konvenční polymerázová řetězová reakce byla prováděna na přístroji Peltier Thermal Cycler. Výsledky: V období od roku 2005 do března 2008 bylo vyšetřeno celkem 337 biologických vzorků od 222 pacientů. DNA Toxoplasma gondii byla detekována u pěti pacientů. Závěr: Polymerázová řetězová reakce je důležitou metodou pro stanovení diagnózy toxoplazmóza u rizikových skupin pacientů (gravidní ženy a imunodefi citní pacienti)., Objective: The aim of the work was to summarize results obtained in the diagnostics of toxoplasmosis by a method of polymerase chain reaction in our workplace. Material and methods: Various biological materials were examined. DNA was isolated by QIAamp DNA Mini kit and QIAamp DNA Blood Mini kit. For amplifi cation TGR1E was selected and conventional polymerase chain reaction was performed on Peltier Thermal Cycler instrument. Results: 337 biological samples from 222 patients were examined from 2005 to March 2008. Toxoplasma gondii DNA was detected in fi ve patients. Conclusion: Polymerase chain reaction is important method for the diagnosis of toxoplasmosis in the risk group of the patients (pregnant women and immunodefi ciency patients)., Tomková Jana, Novotný D., Bednaříková J., Rusiňáková Z., Bartková M., Schmiedová L., Spurná S., and Lit.: 7
