Abstract:
Blood culture, the basic method used in the diagnosis of bacteremia or sepsis, is decisive for patient's treatment. It is emerging whether the isolated microorganism is a causative agent of the infection or a contaminant. The aim of this study was to determine whether Gram-positive microorganisms, which were isolated from blood cultures simultaneously collected from two distinct veins both revealed the same species and same susceptibility profiles as they were causative agents of the bloodstream infection. Among the strains isolated from a total of 67 cultures, which revealed the same species, 52.2% (35/67) were considered to be clinical causative agents and 47.8% (32/67) were considered as skin contaminants. Inoculation of the simultaneous blood cultures collected from two distinct veins should be performed.

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,...
