%X Aim: To determine the efficacy of manuka honey against multidrug-resistant (MDR) and extensively drug-resistant (XDR) clinical strains of Salmonella Typhi. Materials & methods: Clinical isolates were processed using the Bactec blood culture system, identification and antibiogram by Vitek 2 and antibiotic resistance genes through polymerase chain reaction (PCR). Microbroth dilution assays evaluated the antibacterial activity of manuka honey. Results: MDR and XDR-S. Typhi was susceptible to azithromycin. These strains carried the H58, gyrA, gyrB, blaCTX-M-15 , and blaTEM-1 genes. At 100% honey, the zone of inhibition for MDR (15-23 mm) and XDR (15-24 mm) strains. 18/50 MDR and 14/50 XDR strains inhibited at 3.125 v/v% killed at 6.25 v/v% concentration respectively. Conclusion: Manuka honey could be an alternative option for treating S. Typhi infections.<BR>Typhoid fever is a life-threatening bacterial infection caused by the Salmonella Typhi. These bacteria are transmitted through contaminated water and food and cause fever, abdominal pain, headache, vomiting, and diarrhea mainly in children under 5. There are around 9 million people get infected with S. Typhi, with an increased death of 1,10,000 annually. Bees that collect nectar from the blossoms of the Manuka tree in Australia and New Zealand produce a type of honey known as manuka honey. This honey is famous for its antibacterial activity, and potential health benefits. Therefore, we aimed to determine its antibacterial activity against S. Typhi. Our finding shows that the commonly available antibiotics did not kill S. Typhi because their DNA was drug-resistant. After applying the manuka honey, these bacteria were killed and given a clear zone ranging from 15–24mm on the agar plate. Further analysis revealed that at low concentrations of manuka honey, 3.1% and 6.25%, most of the S. Typhi stopped growing and killed, respectively. This study suggested that manuka honey, which is affordable and readily available, could be used as a treatment option to treat infections produced by these harmful bacteria after further analysis.
