Objective:
to investigate the presence of microorganisms in the nostrils of the nursing professionals of a Brazilian teaching hospital.
Method:
cross-sectional study in two inpatient units specialized in HIV/AIDS. Nasal secretion samples of nursing professionals were collected in one month. The samples were processed at the microbiology laboratory of the institution and analyzed using the Statistical Package for the Social Sciences (SPSS) software, version 19.0. Ethical aspects were abided.
Results:
from the 73 members of the nursing staff, samples of nasal secretions were collected from 61 (80.2%). Six types of microorganisms were isolated in 22 (41.0%) positive cultures. It is noteworthy that Staphylococcus aureus accounted for 22.9%, four of them oxacillin-resistant (MRSA).
Conclusion:
Staphylococcus aureus microorganism accounted for the largest prevalence in individuals of this study.

Sputum Studies II: Culture and Sensitivity
Sputum culture and sensitivity is a medical procedure used to diagnose bacterial infections in the respiratory tract and select the most appropriate antibiotics for treatment. This process involves analyzing sputum samples of thick and opaque secretions produced in the lungs and airways. These samples are collected from patients and then sent to the laboratory for analysis.
The test can identify various pathogens responsible for respiratory infections, including Streptococcus,...
