Introduction: Many viral and bacterial respiratory tract infections can present with respiratory signs and progress to complicated pneumonia. In the recent Coronavirus Disease-2019 (COVID-19) pandemic, it is crucial to test all Severe Acute Respiratory Infection (SARI) patients for other microbial infections in addition to COVID-19, enabling timely diagnosis and treatment to reduce morbidity and mortality. The automated system, BioFire FilmArray, utilises multiplex Polymerase Chain Reaction (PCR) to rapidly detect and identify multiple respiratory pathogens, including selected Antimicrobial Resistance (AMR) genes, within an hour. Aim: To detect bacterial and/or viral pathogens associated with hospitalised COVID-19-negative SARI patients using the BioFire FilmArray Pneumonia Panel (BFPP). Materials and Methods: This laboratory-based cross-sectional study was conducted at All India Institute of Medical Sciences (AIIMS), Nagpur, Maharashtra, India, from June 2020 to February 2021. Respiratory samples, such as sputum, tracheal aspirate, Endotracheal (ET) secretions, and Bronchoalveolar Lavage (BAL), were collected from COVID-19-negative hospitalised SARI cases. A total of 81 patients were included in the study. The samples were tested using the BFPP (multiplex PCR) system and processed using conventional culture techniques. Patient characteristics, clinical and laboratory investigation data, and findings of respiratory viral and bacterial agents, as well as antibiotic resistance genes detected by BioFire FilmArray, were recorded using paper case reports. The data were collected and analysed using Statistical Package for Social Sciences (SPSS) software. Results: Out of the 81 clinical samples processed, the BFPP detected 168 bacterial and 18 viral pathogens. Bacterial-viral codetection was observed in 13 (16%) samples. Atypical bacteria were detected in 3% of cases. Among the bacterial pathogens, the AMR gene for New Delhi Metallo-beta-lactamases (NDM) was detected in 42 (25.9%) cases, followed by CTX-M betalactamases, VIM, and the oxacillinase group of β-lactamases. Conclusion: The BFPP test is a valuable tool for the rapid detection of a wide range of pathogens, including associated AMR genes, with high sensitivity and specificity. This can greatly aid in treatment decisions. [ABSTRACT FROM AUTHOR]
