[Application of laser light scattering technique to diagnose catheter-associated infections.]

The results of the bacteriological catheter investigation on the analyzer with the technology of laser light scattering and using D. Maki culture technique coincided in 91.8% of cases. Catheter-associated infections are proven in 8 cases. The following obtained from blood and intravascular catheter in 5 patients: Staphylococcus epidermidis (n=1), Staphylococcus haemolyticus (n=1), Escherichia coli (n=1), Staphylococcus aureus (n=2); Staphylococcus epidermidis (n=1) was detected in 1 child from ventricular shunt and cerebrospinal fluid and Escherichia coli lactose-negative + Staphylococcus haemolyticus were detected in 1 child from ventricular shunt, whily only Escherichia coli lactose-negative was detected from cerebrospinal fluid; Pseudomonas aeruginosa (n=1) was foud out in 1 patient from the urinary catheter and urine. Clinical significance of the isolated microorganisms from the catheter must be assessed in each particular case taking into account its quantity and type of the isolated microorganism.
