Evaluation of lysis filtration as an adjunct to conventional blood culture.
A lysis filtration system was used in conjunction with conventional broth culture for 1112 blood cultures. The system, which entailed collection of 5 ml of blood into bottles containing 50 ml isotonic phosphate buffer, Tween 20, and Rhozyme with subsequent filtration using a 0.45 micron Millipore field monitor, was simple and economical to use. Positive results were obtained earlier than those ...
متن کاملPractical aerobic membrane filtration blood culture technique: clinical blood culture trial.
During the course of preliminary clinical trials of an improved membrane filter blood culture system, filter plugging produced by a gelling of the lysing solution was observed when the patients had high leukocyte counts. A solution of streptokinase-streptodornase (Varidase, Lederle Laboratories) dissolved or prevented the gel and permitted rapid filtration without plugging. With streptokinase-s...
متن کاملConventional Biphasic Broth Blood Culture System
In a comparative fungal blood culture study, a lysis-centrifugation system (Isolator; Du Pont Co., Wilmington, Del.) detected 89% of all episodes of fungemia; the lysis-centrifugation system detected fungemia exclusively or significantly earlier than did a biphasic brain heart infusion bottle system 83% of the time. The lysis-centriguation system was particularly useful in the early detection o...
متن کاملInhibition of pneumococcal autolysis in lysis-centrifugation blood culture.
The recovery of Streptococcus pneumoniae from the Isolator lysis-centrifugation blood culture has been low in many studies. The poor survival of pneumococci was not due to toxicity of the Isolator medium but to autolysis before plating. This autolysis was completely inhibited by adding 10 mM phosphorylcholine to the Isolator medium.
متن کاملEvaluation of conventional castaneda and lysis centrifugation blood culture techniques for diagnosis of human brucellosis.
We investigated the role of the lysis centrifugation blood culture technique over the conventional Castaneda technique for the diagnosis of human brucellosis. The lysis centrifugation technique has been found to be more sensitive in both acute (20% higher sensitivity; P < 0.00001) and chronic (40% higher sensitivity; P = 0.087) forms of brucellosis. The major advantage of lysis centrifugation w...
