Introduction: In critically ill patients, there is a defect in host defense mechanism resulting in increased susceptibility to bacterial and fungal infection. The pattern of organisms causing infections varies between different countries and hospitals; therefore it is important that every hospital generates antibiograms to guide healthcare professionals during treatment with optimal choice of antibiotics. Our study aimed to described the pattern of fungal and bacterial pathogen in patients with high risk for invasive fungal disease (IFD).
Methods: An observational study was conducted in Cipto Mangunkusumo Hospital, Jakarta, Indonesia, within March-September 2015. Specimens were taken from blood, sputum, endotracheal aspiration, bronchoalveolar lavage (BAL), urine, pus and drainage fluid/surgical tissue specimen on 5th-7th day of hospitalization. Samples were cultured onto suitable culture media and bacterial isolates were identified using standard biochemical methods.
Results: Bacteria and Candida sp. were isolated from 153 patients. C. tropicalis (44.31%) was the commonest fungal isolated. Incidence of gram-negative bacteria was higher than gram-positive bacteria. Klebsiella pneumonia was the most common gram-negative bacteria isolated, where as Enterococcus faecalis for gram-positive bacteria.
Conclusion: Critically ill patients were vulnerable to contracted fungal and bacterial pathogen. Candida non-albicans and Gram-negative bacteria were the most common pathogen detected among critically ill patients with high risk for IFD.
