Abstract


Background: Burkholderia cepacia is highly virulent and multidrug resistant organism to cause fatal and serious infections in ICUs leads to rise in mortality and morbidity. aim of present study was to know the prevalence of Burkholderia cepacia in blood stream infection in Intensive Care Unit and to know the drug susceptibility.

Methods: This is a prospective study was carried out in the Intensive Care Unit and Department of Microbiology, Narayana Medical College, Nellore, from February to March 2018. As a part of routine investigations Blood, urine, sputum or tracheal secretions sent for culture and sensitivity to the Microbiology laboratory. By conventional method, all the samples were cultured (except blood) onto Blood agar, Chocolate agar and MacConkey, s agar; incubated for 18-24 hours at 37⁰C. Blood cultures were performed in BACT/ Alert 3D (Biomeriux), only positives were subculture by conventional method. Further analysis was done in culture positive samples only.

Results: A total of 448 patients admitted in ICU were included in the study, from them 586 samples were collected. out of which we got 238 culture positives. Among them 19 patients were positive for Burkholderia cepacia, most of them isolated from blood (78.9%), followed by respiratory secretions (21.1%) and none of them were isolated from urine samples. Most of the isolates were sensitive to Meropenam and Tigecycline (89.4%) followed by minocycline (84.2%), ceftazidime (73.6%), levofloxacin (63.1%). While B. cepacia isolates showed high resistance to cefaperazone-sulbactam, ciprofloxacin, ticarcillin-clavulanic acid with (84.2%), (89.4%), (89.4%) respectively.

Conclusions: To conclude that, Burkholderia cepacia is one of the emerging causes of septicemia with multidrug resistance, cross contamination may be the root cause so it should be treated quickly and effectively.
