The world is seeing a continuous rise in the levels of antibiotic resistance1. Organisms develop new resistance mechanisms, emerge, and spread the resistance worldwide, making it challenging to treat common infectious diseases. In the current study, clinical isolates received between the years 2017 to 2020 were cultured and the isolated organisms were screened for antibiotic resistance; isolates with multiple drug resistance were further subjected to confirmatory screening through Combined Disc Test (CDT) and Modified Hodge Test (M.H.T.), and molecular characterization to be finally tested for gene expression analysis. Molecular characterization involved screening of genes blaVIM-2, blaKPC-3, blaNDM-1, and blaIMP-11 responsible for imparting carbapenem drug resistance2. From the laboratories of tertiary care hospitals, a total of 1452 clinical isolates were collected and identified. The organisms were subjected to antibiotic susceptibility screening and carbapenem resistance screening. The isolates found positive in the screenings were subjected to molecular characterization for genes, blaVIM-2, blaKPC-3, blaNDM-1, and blaIMP-11, responsible for imparting carbapenem drug resistance. Most of the isolates were resistant variably to aminoglycosides but were found to be resistant to fluoroquinolones and β-lactams group of antibiotics. Carbapenem activity was detected in twelve percent of total isolates and 27 percent among multidrug-resistant isolates. blaNDM-1 gene was found present in 77% isolates, and five organisms among the total number of organisms showed pan drug resistance.

Hospital Acquired Infections (HAIs) are a significant concern for healthcare setups, as it increases the overall cost of treatment, patients stay in hospitals, making them susceptible to secondary and tertiary infections and, sometimes, mortality1. To prevent or control HAIs, evaluating the organisms isolated from the critically maintained areas is considered of epitome importance and everlasting practice in the healthcare industry. Identifying such organisms and screening them for antibiotic resistance is mandatory, but it also helps professionals understand colonization trends. Sensitive areas of healthcare setups were screened monthly from years 2017 to 2020. A total of 4400 samples of hospital hygiene, e.g., intravenous drip stands, ventilator surface, anesthetist’s trolley, patient’s bed, instrument trolley, etcetera, were collected. Isolated organisms were cultured and screened using the CLSI technique. E. coli, Pseudomonas spp., and Klebsiella spp. were found in both previous to COVID current samples. Multidrug-resistant organisms were subjected to molecular characterization to detect the presence of carbapenem genes. Evaluation data of both pre-and during Coronavirus Disease or COVID-19 were compared. The prevalence of pathogenic (Klebsiella spp., E. coli, and Pseudomonas spp.) and non-pathogenic (Staphylococcus aureus and Bacillus spp.) strains in healthcare setups decreased drastically (Klebsiella spp. from 80% to 20%, E.coli from 90% to 10% and Pseudomonas spp. from 80% to 20%). It is possible only because of the awareness in non-specialists and healthcare workers due to the unforeseen critical situation proving to be a blessing for the future generation.
