comparison of the microbial load of incoming and distal outlet waters from dental unit water systems in istanbul.	this is a cross-sectional study of the incoming and distal outlet water quality from 41 dental units in istanbul, carried out to compare the total microbial loads using traditional culture method versus epifluorescence microscopy. the possible presence of legionella pneumophila using traditional culture method was also analyzed. one hundred and twenty three samples were taken from the high-speed handpiece lines, air-water syringe lines and source (incoming) water supplies from 41 dental units. t ...	2009	18843542
postantibiotic effect of various antibiotics on legionella pneumophila strains isolated from water systems.	the postantibiotic effects (pae) of azithromycin, clarithromycin, ciprofloxacin, and levofloxacin were investigated against legionella pneumophila (l. pneumophila) strains isolated from several hot water systems of different buildings in istanbul. each strain in logarithmic phase of growth was exposed to concentrations of antibiotics equal to minimum inhibitory concentration (mic) and 4× mic for 1 h. recovery periods of test cultures were evaluated after centrifugation using the viable counting ...	2012	22627604
growth ability of gram negative bacteria in free-living amoebae.	when bacteria and free-living amoebae (flas) live both in natural waters and man-made aquatic systems, they constantly interact with each other. some bacteria can survive and grow within flas. therefore, it has recently been thought that flas play an important role in spreading pathogenic bacteria in aquatic systems. in this study we investigated the intracellular growing ability of 7 different gram-negative bacteria (pseudomonas fluorescens, pseudomonas putida, pasteurella pneumotropica, aeromo ...	2014	24955522
