    Infective endocarditis is one of the major heart conditions that pose a challenge to cardiology, with a high mortality rate. The microorganisms that cause this disease are diverse, with most cases linked to streptococci and staphylococci, and Staphylococcus aureus being the most prevalent in developed countries. In diagnosing infective endocarditis, pathological examination is more sensitive than valve culture. It has been shown that there are cases of culture-negative endocarditis, as well as those negative for conventional Gram staining. However, using the modified Brown-Brenn Gram stain, the result was positive, which led to therapeutic failures due to poor disease management. Considering the importance of the laboratory in aiding diagnosis, this study will evaluate the performance, in terms of sensitivity and specificity, of both the Gram stain and the modified Brown-Brenn Gram stain for diagnosing bacterial endocarditis at the INCOR.
