“…The most frequent microorganisms found in the samples collected were similar to those from previous studies: Staphylococcus aureus and Pseudomonas aeruginosa. Nonetheless, we found a higher number of gram-negative aerobic bacteria than was reported in other studies 2,15,26,27 . Comparing the samples collected with the syringe with those collected with the suction trap, we observed the same results in 71% of the patients.…”

There is still controversy on which is the best method to collect the secretion directly from the middle meatus or maxillary sinus in patients with chronic rhinosinusitis. Aim:To evaluate the prevalence of bacteria in patients with chronic rhinosinusitis and compare the suction trap collector to direct aspiration attached to a syringe for the microbiological analysis of these secretions. Materials and Methods:Prospective study involving 31 patients who underwent endoscopically guided maxillary secretion aspiration by two different methods (aspiration with the collector tube "suction trap" and aspiration with the use of a catheter connected to a syringe), to determine the microbiological diagnosis and to compare the two methods used.Results: microorganisms grew samples collected from 55% of the 31 patients. The most frequent bacteria were S. aureus, Pseudomonas aeruginosa and other aerobic Gram-negative bacteria. The results from cultures were similar between the two methods in 71% of patients. Conclusion:S. aureus, Pseudomonas aeruginosa and other aerobic Gram-negative bacteria make up the main flora in the maxillary sinus of the patients. There was good correlation between the microbiological results obtained by using a catheter attached to a syringe and the "suction trap" nasal collector. Braz J Otorhinolaryngol. 2010;76(3):321-5.

“…We noticed a predominance of coagulase-negative Staphylococcus (12.1%) and Staphylococcus aureus (9.7%) agreeing with other authors 7,[10][11][12][13][14]17 . The role of coagulase-negative Staphylococcus in the pathogenesis of CRS is still not clear 18 .…”

Chroni c rhinosinusitis microbiology studies show the presence of aerobe and anaerobe microorganisms, fungus and virus and their incidence vary according to each study. These studies guide us on choosing the most adequate antimicrobial agent to eliminate the infectious process, thus, helping in restoring rhinosinusal mucosa. Study design: Clinical prospective. Aim: This work aimed at studying the microbiology of the maxillary and/or ethmoid sinuses of patients with chronic rhinosinusitis and with indication of functional endoscopic sinus surgery. Materials and methods: During surgery, we collected secretion and/or fragments of maxillary and/or ethmoid sinus mucosa from 41 patients to perform Gram stain, fungus direct research, aerobe and anaerobe microorganism culture and fungus culture. Results: We identified the presence of aerobe microorganisms in 21 patients (51.2%), anaerobe microorganisms in 16 (39%) and fungus in 1 (2.4%). In the studied population, only 12 patients (29.2%) presented microorganisms considered pathogenic when analyzed together with the semiquantitative leukocyte count. Staphylococcus coagulasenegative and Staphylococcus aureus were the most frequent microorganisms found, in 5 (12.18%) and in 4 (9.75%) patients respectively. Conclusion: This study reveals that Staphylococcus coagulase-negative and Staphylococcus aureus were the most frequent microorganisms isolated from patients with chronic rhinosinusitis.

Although many investigations on the bacteriology of chronic sinusitis have been reported, there is still much discussion about the physiological flora of the nose and paranasal sinuses, the role of the various aerobic and anaerobic "pathogenic" bacteria, and the influence of the anatomical location from which samples for bacteriology are taken. We conducted a qualitative and semi-quantitative bacteriological examination of patients with chronic sinusitis undergoing a transnasal sinus operation (patient group), and of patients without chronic sinusitis undergoing a septoplasty (control group). In both groups brush smears of the inferior nasal turbinate and biopsies of the middle nasal turbinate were taken, with additional biopsies of the maxillary sinus and ethmoidal bulla in the chronic sinusitis group. In both groups coagulase-negative staphylococci were identified in almost all samples. Staphylococcus aureus was found in 22% (middle turbinate) to 33% (inferior turbinate) of the samples from the control group and in 33% (maxillary sinus, middle turbinate) to 50% (inferior turbinate) of the samples from the patient group. Other (pathogenic) aerobic bacteria were found much more rarely and only slight distinctions between control and patient group were observed. The concentrations of the different bacterial species (colony-forming units) were comparable in both groups. Strictly anaerobic bacteria and fungi were not identified. Only small discrepancies between the various methods and/or locations of sampling were found. Based on our bacteriological findings a differentiation between patients with and without chronic sinusitis was not possible. These results shed doubt on the clinical value of bacteriological examinations of nasal and paranasal mucosa in patients with chronic sinusitis.
