Teeth displaced from their alveolar bone can be replanted if properly handled and stored in suitable environments. To help minimize the failure of reimplantation, teeth should be preserved in a storage environment that is initially free of bacteria. Research objective: Evaluating the morphology of bacteria on the periodontal ligament cells in different storage environments at various time points after the teeth have been removed from the alveolar bone using Gram staining.

The study investigated the antifungal activity against Aspergillus niger CBS 76997 and Penicillium oxalicum 20B of several Lactobacillus strains (LAB). The in vitro antifungal activity of cell-free supernatants and biomass of Lactobacillus strains against the growth of A. niger CBS 76997 and P. oxalicum 20B was determined by monitoring the fungal colony diameter over time by spot inoculation method and double layer method.

Water quality plays an immensely significant role in safeguarding the health of humans and other species on the planet. Polluted water sources can contain harmful substances such as heavy metals, pesticides, bacteria, and viruses, which can pose threats to human health and other organisms. Water quality is also a crucial factor in protecting the environment and sustaining the ecosystems of freshwater and marine environments. Polluted water sources can impact the lives of aquatic animals and plants, causing harm and endangering biodiversity by disrupting the food chain.

Recent advancements in metagenomics, particularly in the studies of conservative 16S rRNA sequences, have significantly accelerated our understanding of the relationship between corals and their associated microbial communities. While bacteria are known to be closely linked with corals, there is limited understanding of the connections between archaea and corals. Unlike previous 16S rRNA studies conducted in similar tropical coral reef ecosystems, we analyzed both the archaeal and bacterial communities associated with Acropora sp. and Lobophyllia sp.

Mango seeds (Mangiferin indica L.) have the ability to inhibit P. acnes, S. aureus, and E. coli bacteria and inhibit inflammation, potentially for transdermal therapeutic dosage forms. The nano-emulsion dosage forms were prepared based on the SNEDDS system with nano-oil droplets containing mango seed extract. These dosage forms contributed to carrying the active ingredient deeply into the impact site, bringing the highest efficiency, but this needs to be proven.

Helicobacter pylori is a bacterium associated with gastric diseases and disorders of the upper gastrointestinal tract. The gram-negative bacterium Helicobacter pylori is known as a persistent colonizer of the human stomach, and this bacteria is also involved in extra-intestinal diseases. In 1994, the International Agency for Research on Cancer, World Health Organization classified H. pylori as a class 1 carcinogen, the only bacterium given this classification.

Bacterial infections have a substantial impact on global health and can become serious if misdiagnosed with several diseases related to the central nervous, cardiovascular, and respiratory systems. The prognosis in patients with infectious disease strongly depends on early diagnosis and appropriate antibiotic therapy. We aimed to compare the accuracy of genus and species-level identification bacteria using biochemical testing and 16S rRNA sequence analysis.

FtsZ is conserved in almost all bacteria and is an essential protein for bacterial cell division. The cell division is prevented by the inhibitors against FtsZ’s functions. Thus, FtsZ is known as an attractive, and underexploited novel antibacterial target protein. The aim of this research is searching for new antibacterial agents from 72 plants collected in Central Vietnam.
