CORRELATION OF DIRECT GRAM SMEAR FINDINGS WITH BACTERIAL ISOLATION IN SPUTUM OF PATIENTS.
Abstract
Introduction:-
The Gram stain is a bacteriological laboratory technique used to differentiate between gram positive and gram negative bacteria. The most important primary test performed directly on clinical specimen is gram staining.
Aims and Objective:-
To correlate the gram stain findings with the bacteria isolated from the sputum samples obtained from patients
Materials required:-
This is a retrospective study conducted for a period of 6 months (June 2018 and December 2018) at Department of Microbiology in Saveetha Medical College and Hospital, Chennai.
Results:-
The sputum collected from 109 patients from different departments was sent to the microbiology laboratory and following data has been arrived.
Conclusion:-
1. Most common bacterial isolate from sputum was Pseudomonas aeruginosa.
2. The presence of pus cells between 10 to 25 had a better correlation than that of pus cells less than 10.
3. The epithelial cells had an inverse correlation with isolation of pathogen.
