In the present study the results of the traqueal secretion samples had been used, for constatao of the bacteria with bigger taxes of prevalence. The analysis was after made the collection of the data, tabulated and represented graphically in the spread sheet of the program of Windows 2011 (Excel). Results In the present research, the March of a 2011, total of 372 samples was evaluated retrospectively in the period of March of 2010 being that 108 (29.03%) had presented microrganismos and 264 (70.97%) had been negative. Of the 108 positive samples, one totalized a percentage of 48,14% of the masculine sort, 40.74% of feminine sort and 11.12% of just born. In relation to the profile of samples collected 88.88% had been proceeding from adult UTIs and 11.12% of the UTIs neo-Christmas. The analyses carried through through the identification letters, had shown following species: 38.9% Acinetobacter baumannii; 0.9% Candida albicans; 0.9% Citrobacter freundii; 1.9% Escherichia coli; 0.9% Enterobacter aerogenes; 1.9% Enterobacter cloacae; 8.4% Klebsiella pneumoniae; 0.9% Proyour mirabilis; 23.1% aeruginosa Pseudomonas; 0.9% Serratia marcescens; Aureus 13.9% Staphylococcus; 1.9% Staphylococcus epidermidis; 0.9% Staphylococcus haemolyticcus; Hominis 0.9% Staphylococcus; 0.9% Staphylococcus saprophyticus; 1.9% maltophilia Stenotrophomonas and 0.9% Streptococcus pneumoniae, as shows table 1. The present study it demonstrates that 86 (79.6%) cepas had presented greater prevalence of Gram-negative microrganismos: Acinetobacter baumannii, aeruginosa Pseudomonas, klebsiella pneumoniae, Proyour mirabilis, Serratia marcescens, maltophilia Stenotrophomonas, Citrobacter freundii; Escherichia coli; Enterobacter aerogenes Enterobacter cloacae. Positive Gram coconuts had represented 21 (19.5%): Staphylococcus aureus, Staphylococcus epidermidis; Staphylococcus haemolyticcus Staphylococcus hominis; Staphylococcus saprophyticus and Streptococcus pneumoniae.
It also demonstrated to 1 (0.92%) Candida albicans. Quarrel the nosocomial or hospital pneumonia represents a problem for the public health, therefore she is one of the death causes most common enters the acquired infections in nosocomial environment, acometendo public and particular hospitals. The pneumonia is provoked by any infectious agent, however the bacteria are root causes 7,8.
