The emergence of resistance against commonly used antibiotics has become a serious global concern. The rapid development of antibiotic resistance exhibited by Enterobacteriaceae has caused an increasing concern regarding untreatable bacterial infections. Here, we isolated four pathogens from a geriatric female patient who was hospitalized for a month with ventilator-associated pneumonia (VAP) and fever. The organisms isolated from the tracheal aspirates and urine included Klebsiella pneumoniae, pandrug-resistant Providencia rettgeri, and Acinetobacter baumannii. Resistome analysis indicated that the bacterial isolates from the polymicrobial infection were multiple-drug resitnat and pandrug resistant clones. Molecular characterization revealed presence of blaTEM-1 in K. pneumonaie, P. rettgeri and A. baumannii. The blaTEM-1 and blaNDM-1 genes were present in P. rettgeri and A. baumannii, whereas the blaTEM-1, blaNDM-1 and blaOXA-23 traits were present in A. baumannii isolates. The patient has died due to the unavailability of effective antimicrobial treatment for this drug-resistant polymicrobial infection.
