“…From the results, it can be seen that the concentrations 75% of the extract against Streptococcus pyogenes and Klebsiella pneumoniae gave a higher inhibition zone compared to other concentrations. This due to the sensitivity of the extract depends on the level of the concentration when it is used against certain microorganisms [9].…”

Melastoma malabathricum L. leaves is a traditional plant native to tropical Asia, subtropical, and Pacific islands. This study aimed to investigate the antibacterial activity of senduduk leaves (Melastoma malabathricum L.) against bacteria Streptococcus pyogenes,and Klebsiella pneumonia. Method of extraction done by maceration using ethanol 70% to get the extract. The antibacterial activity of the extracts was determined by using Kirby-Bauer Disc Susceptibility Test and with a concentration of 25%, 50% and, 75%. The inhibition zone was recorded from senduduk leaves (Melastoma malabathricum L.) extract to indicate the highest antimicrobial activity from this plant. Based on the results of this study, the extract leaves can inhibit the growth of Streptococcus pyogenes in concentration 75% (21.8 mm) and Klebsiella pneumonia in concentration 75% (16 mm). The phytochemical analysis detected the presence of alkaloids, flavonoids, saponins, tannins, and terpenoids. The findings may be helpful to future investigators in identifying alternative and new bioactive secondary metabolites like antibiotics to treat resistant human pathogens.

“…These have been reported from a few marine invertebrates from Porifera, Cnidaria, Anthozoa, Tunicates, Mollusca, Echinodermata, etc. ( Cabeza et al, 2021 ; Chamika et al, 2021 ; Mayefis and Widiastuti, 2021 ; Ramesh et al, 2021 ; Riccio et al, 2021 ; Sibiya et al, 2021 ; Singh et al, 2021 ; Tsvetkov et al, 2021 ; Wewengkang et al, 2021 ). The number of bioactive compounds from marine sources has been increasing linearly, i.e., 25 in 1972, 300 in 1982, 1,500 in 1992, and over 6,000 today, and more than 3,300 compounds are reported from sponges only ( Bérdy, 2005 ).…”

Phylum Nematoda is of great economic importance. It has been a focused area for various research activities in distinct domains across the globe. Among nematodes, there is a group called entomopathogenic nematodes, which has two families that live in symbiotic association with bacteria of genus Xenorhabdus and Photorhabdus, respectively. With the passing years, researchers have isolated a wide array of bioactive compounds from these symbiotically associated nematodes. In this article, we are encapsulating bioactive compounds isolated from members of the family Heterorhabditidae inhabiting Photorhabdus in its gut. Isolated bioactive compounds have shown a wide range of biological activity against deadly pathogens to both plants as well as animals. Some compounds exhibit lethal effects against fungi, bacteria, protozoan, insects, cancerous cell lines, neuroinflammation, etc., with great potency. The main aim of this article is to collect and analyze the importance of nematode and its associated bacteria, isolated secondary metabolites, and their biomedical potential, which can serve as potential leads for further drug discovery.
