Abstract

Background: the capacity of some stumps of negative coagulase staphylococcus to produce biofilm has been considered by some authors as index of virulence and it is useful to differentiate them of those polluting stumps.
Objective: to determine the relationship between the biofilm production for stumps of negative coagulase staphylococcus and epidemic clinical variables.
Methods: an observational, analytical cross-sectional study was conducted in stumps of negative coagulase staphylococcus and the relationship between the biofilm production and the selected clinical-epidemic variables of the infected patients, in the Microbiology laboratory in "Saturnino Lora” hospital in Santiago de Cuba, from January to December 2012.
Results: the age groups who had more isolation to negative coagulase staphylococcus, in male and female sex was the 50-59 and the over 60 one. Regarding the non-communicable chronic diseases associated presented in the patients studied, it was observed that the highest number of affected people was those that presented diabetes mellitus and chronic nephropathies. The biggest figure of isolations to negative coagulase staphylococcus corresponded to the nephrology service. The antimicrobials that showed smaller resistance percentage were Vancomycin, Chloramphenicol, Novobiocin, and Doxicicycline.
Conclusions: the infection for negative coagulase staphylococcus is frequent in patient with advanced age, and diabetes mellitus and nephropathies are factors to keep in mind. Finally it was demonstrated that the red congo agar means, for their simplicity, high sensibility and specificity can be added to the diagnostic arsenal in our laboratories for the biofilm detection.
