Concerns about reports of antibiotic-resistant bacterial infections in hospitals and the community have been widely covered in the media, along with remarks about the possibility that we could soon run out of antibiotics as a means of controlling infectious illness. Infections caused by Enterococcus faecium, Staphylococcus aureus, Klebsiella species, Clostridium difficile, Acinetobacter baumannii, Pseudomonas aeruginosa, Escherichia coli, and other Enterobacteriaceae species place a significant impact on public health. Despite the pharmaceutical industry’s lack of interest in the area over the previous decade, microbial natural products remain one of the most exciting sources for identifying and developing new antibacterials. Microbial natural product screening and development research is now benefiting from advances gained in other relevant domains. Microbial ecology, analytical chemistry, genetics, molecular biology, and synthetic biology are some of the disciplines studied. Antibacterial treatment has saved millions of lives and lowered the risk of premature mortality from bacterial illnesses significantly. These accomplishments led to the idea that harmful germs and high infectious disease mortality would be a thing of the past. These include antibiotic molecule detoxification and mutations in the targeted target, or, as recently reported, are mediated by population-level resistance mechanisms. Interspecies and intraspecies horizontal gene transfer of Gram-negative and Gram-positive bacteria is currently recognised as the major route by which bacteria become multiresistant. The motor driving this trend is the selective pressure of antibiotic usage in hospitals, communities, and agriculture. Bacterial resistance to all presently used antibiotics has evolved in both Gram-positive and Gram-negative bacteria. This perilous scenario necessitates an immediate international response by governments, the pharmaceutical sector, biotechnology businesses, and the academic community to respond and promote the development of new antibacterial drugs. One such initiative endeavour is the Infectious Diseases Society of America (IDSA) request to develop ten novel systemic antibacterial medicines by 2020, with a focus on Gram-positive and Gram-negative bacteria. Unless immediate action is taken, the current severe and hazardous situation may return us to the pre-antibiotic age, when there was no treatment for bacterial illnesses. Multidrug-resistant bacterial infections pose a significant public health burden. not just in terms of morbidity and death, but also in terms of higher costs for patient management and infection control measures. The death rate from multidrug-resistant bacterial infections is high. In 2002, it was claimed that 1.7 million healthcare-associated infections occurred in American hospitals each year, resulting in around 99,000 fatalities. This is a significant rise over a prior estimate, which said that around 13,300 persons died from hospital-acquired illness in 1992. Each year, around 37,000 people die as a direct result of a hospital-acquired illness in the EU, Iceland, and Norway; an additional 111,000 die as an indirect effect of a hospital-acquired infection; and approximately 25,000 patients die from a multidrug-resistant bacterial infection. Currently, the most common MDR bacteria include Enterococcus faecium, Staphylococcus aureus, Klebsiella pneumoniae, Acinetobacter baumannii, Pseudomonas aeruginosa, and Enterobacter spp., which were dubbed “ESKAPE” after being first identified, with some reports adding Clostridium difficile or additional Enterobacteriaceae. Gram-positive bacteria such as Staphylococcus aureus, Streptococcus pneumoniae, Enterococcus faecalis, and Clostridium difficile cause a high share of severe infections globally. An growing proportion of such Gram- positive isolates are resistant to first-line treatments. The quality and diversity of new microbial strains, as well as the methods employed to harness their metabolic diversity, are critical components of microbial natural product libraries. Historically, access to microbial diversity was based on intense collection and isolation using conventional techniques from a wide variety of geographical locations and environments, with recurring isolation and screening of the dominating species. species, as well as a poor likelihood of isolating new chemicals. Although projections for Streptomyces spppotential. generation of undiscovered new compounds were high, the truth is that species dispersed widely in varied settings generate the same well-known and structurally similar antibacterial chemicals. Current techniques to new chemical discovery mostly attempt to target particular and minor microbial populations in unique or underexplored habitats, such as distinct terrestrial niches, plant host-microbe relationships, and marine ecosystems. Environmental variables are powerful selective factors, and the distribution of some microbial species, especially in very prevalent taxa, exhibits biogeographic patterns influenced by microenvironmental conditions, which can be converted into new chemicals. Many research groups have recently highlighted the discovery of hitherto unknown microbial communities linked with rhizospheres and plant endophytes. Lichens, endolithic microbial communities, insect parasites, endosymbionts, sea sediments, and invertebrates are also examples. These methods have encouraged the isolation of new microbial communities capable of creating novel chemical scaffolds.
