Abstract:A total of 1,002 urine specimens were evaluated by laser nephelometry. This technique was compared with both colony counts, done with a calibrated loop, and serial dilutions. For urine specimens containing between 104 and 105 bacteria per ml, laser nephelometry detected 75.4% of those detected by colony coùnt and 65.6% of those detected by serial dilution. For specimens where the concentration of bacteria was greater than 105 per ml, laser nephelometry detected 95.8 and 92.4% of those detected by colony count … Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
