Antimicrobial resistance (AMR) has become a worldwide environmental and public health problem, causing more than 250,000 deaths per year. Unregulated usage, unsafe hospital practices, and misuse in veterinary contribute to the development of multidrug resistance in various bacteria. Hospital water was hypothesized to be a hotspot for AMR transmission because of (1) increased exposure to antibiotic load, (2) poor drainage and sanitation system, (3) interaction between environmental and clinical microbes. The purpose of the research was to assess the biodiversity and AMR in hospital tap waters. MethodologyIn this study, the microflora of the hospital tap water and hospital surfaces was observed by obtaining water samples from the intensive care unit (ICU), surgical wards, and washrooms. These were processed through membrane filtration and spread on seven different

Background With the growth of global terrorism and rapid advancements in the field of science, the threat of a nuclear, biological, and chemical (NBC) attack remains imminent. This study assesses perceptions of preparedness of health care professionals in case of an NBC attack/incident in a tertiary care hospital. Patients and methods We conducted a descriptive, cross-sectional study of 200 health care workers (including nurses and doctors) in a tertiary care hospital, from October 2018 through December 2018. Participants answered 17 yes/no questions and five 5-point Likert scale questions. We analyzed the data using chi-square tests and one-way analysis of variance. Results Most participants (73.6%) reported availability to an isolation facility, and a majority of participants (72%) reported they had access to ventilators. Approximately 60% of participants reported they had access to beds, and 44.6% reported access to a laundry facility. Most participants (65.3%) knew of an employee assistance program while 31.1% did not know about such a program at their institution. More than 50% of the respondents think they can deal with an emergency involving an NBC attack while 60% of the respondents did not think that their institution would be able to protect them in the event of an NBC attack/incident. Overall, the participants were not adequately prepared for a mass scale NBC incident. The level of preparation was linked to the number of courses and training programs completed by the participants, with postgraduate medical personnel having the maximum level of preparedness, followed by medical graduates and nursing personnel. Conclusion Given the inadequate level of preparedness for an NBC incident as indicated by our findings, drills and seminars on large-scale emergencies such as an NBC attack should be included in the curriculum of undergraduate medical and nursing students in order to impart them the necessary training and confidence in dealing with an NBC incident.

The emergence of multidrug-resistant pathogens such as methicillin-resistant Staphylococcus aureus (MRSA), the chief etiological agent for a range of refractory infections, has rendered all β-lactams ineffective against it. The treatment process is further complicated with the development of resistance to glycopeptides, primary antibiotics for treatment of MRSA. Antibiotic combination therapy with existing antimicrobial agents may provide an immediate treatment option. Minimum inhibitory concentrations (MICs) of 18 different commercially available antibiotics were determined along with their 90 possible pairwise combinations and 64 triple combinations to filter out 5 best combinations. Time-Kill kinetics of these combinations were then analyzed to find collateral bactericidal combinations which were then tested on other randomly selected MRSA isolates. Among the top 5 combinations including levofloxacin-ceftazidime; amoxicillin/clavulanic acid-tobramycin; amoxicillin/clavulanic acid-cephradine; amoxicillin/clavulanic acid-ofloxacin; and piperacillin/tazobactam-tobramycin, three combinations were found to be collaterally effective. Levofloxacin-ceftazidime acted synergistically in 80% of the tested clinical MRSA isolates. First-line β-lactams of lower generations can be used effectively against MRSA infection when used in combination. Antibiotics other than glycopeptides may still work in combination.
