Abstract: The emergence of resistant bacteria strain has become a global health concern. It encourages the exploration of potential antibacterial agents, particularly from natural sources. The aim of this study was to investigate the antibacterial activity of ethanol extract of root, stems, leaves, and flowers of Polygonum pulchrum Blume against Staphylococcus aureus and Escherichia coli, through disc diffusion method using cup-plate method. Inhibition zone against S. aureus from roots, stems, leaves, and flowers ethanol extract were 3.5 mm, 2.5 mm, 2.25 mm, and 2.62 mm, respectively, while the inhibition zone against E. coli were 2.25 mm, 2.12 mm, 1.62 mm, and 1.75 mm, respectively. In conclusion, ethanol extract of root, stem, leaves, and flower of P. pulchrum Bl possessed weak antibacterial activity against S. aureus and E. coli. Keywords: P. pulchrum Bl, antibacterial, E. coli, S. aureus, cup-plate technique

The Antibiotic Resistance Crisis: Part 1: Causes and Threats
TL;DR: Decades after the first patients were treated with antibiotics, bacterial infections have again become a threat because of the rapid emergence of resistant bacteria-a crisis attributed to abuse of these medications and a lack of new drug development.

Alkaloids: an overview of their antibacterial, antibiotic-enhancing and antivirulence activities.
TL;DR: The synthetic isoquinoline alkaloid virstatin, for example, inhibits the transcriptional regulator ToxT in Vibrio cholerae, preventing expression of cholera toxin and fimbriae and conferring in vivo protection against intestinal colonisation.

Berberine Targets Assembly of Escherichia coli Cell Division Protein FtsZ
TL;DR: The inhibitory role of berberine is established as a novel FtsZ inhibitor that halts the first stage in bacterial cell division, establishing it as a new drug molecules that would target novel proteins in the prokaryotic system.
