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.

Tinidazole (TNZ) demonstrates greater efficacy against anaerobic bacteria, particularly Gram-negative strains, compared to metronidazole. This study aimed to formulate an in situ gel containing preformed Eudragit RSPO-based nanoparticles (NPs) of TNZ and to evaluate its physicochemical properties.

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.

This study aims to investigate the synthesis capability of the plant growthpromoting substance indole acetic acid (IAA) by the salt-tolerant phosphate-solubilizing Pantoea sp. TTB4.1 strain and its effect on the germination ability of corn seeds immersed in bacterial suspension.

Acne vulgaris is an inflammatory disease of the pilosebaceous unit, especially in adolescents. There are many classifications of the disease severity, and the role of bacteria in the pathogenesis has been confirmed. This article evaluates the severity of acne through the Global Acne Grading System and Investigator’s Global Assessment, and the presence of bacteria in the pustule.

In Vietnam, a number of recent epidemiological studies demonstrated that the prevalence of antibiotic-resistant bacteria has been rapidly increasing, especially in intensive care units (ICUs). Objectives: For patients in the ICU of Hue University of Medicine and Pharmacy Hospital: (1) To survey of usage of antibiotics, and (2) to find out patient-related factors for antibiotic use.

In this study, Cat Hai fish sauce, one of the major traditional fish sauce manufacturers in Vietnam, was used to investigate the variation in histamine content during the fermentation process and to isolate histamine-producing bacteria. Six Dich Chuop samples corresponding to the first sixth months from the beginning of fermentation were collected for these purposes.

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. corals, as well as the surrounding sediment and water columns in Phu Quoc Island, Kien Giang Province, Vietnam.

The thesis investigates the growth promoting effects of plant growth promoting bacteria (PGPB) in chickpea and wheat. Three main topics covered are: 1) Isolating local Plant Growth Promoting Bacteria; 2) Screening and characterization of isolates; 3) Assessment and identification of the selected strains.

In this Masters thesis computational modelling techniques were employed to investigate iron-free apo-Lactoferrin (apo-Lf) structural conformation changes in the presence of variant temperature and pH. These conditions represent the environment most milk protein goes through in food processing and the production of food products.

General objectives: Creating of attenuated mutant Vibrio parahaemolyticus strains causing immune response for fish to develop production of vaccines against nephrotic and hepatic necrosis disease for some marine fish.

Objectives: The aims were to evaluate the effects of some selected endophytic bacteria strains on growth, development of Robusta coffee in a greenhouse and in field conditions. Based on these results, further studies were conducted to determine the effective dose and compatible combination of these strains on the growth and yield of the coffee in the field.

Analyzing the diversity of cellulases and modular cellulases of microbial community in rumen goat by Metagenomics; analyzing the diversity of cellulases and modular cellulases of microbial community in rumen goat by Metagenomics.

Describe the current situation and some related factors causing Hospital acquired pneumonia at the Department of Intensive care and Poison control in Thai Binh Provincial General Hospital in the years 2016-2017. Determine the infection rate and antibiotic resistance characteristics of some bacteria causing Hospital-acquired pneumonia in the Department of Intensive care and Poison control in Thai Binh Provincial General Hospital in the years 2016-2017.

Zinc is used as an anti-gingivitis agent in oral care products and affects multiple targets in oral bacteria. We found that it acts also to suppress respiration of oral streptococci and of Fusobacterium nucleatum, an organism associated with development of gingivitis.

Alkaline pulping liquors are the problematic for environment due to their toxicity and poor biodegradability. During last decade, anaerobic treatment technology has been successfully applied to various types of pulp and paper industry effluents. In the present study, the treatment of highly toxic pulping liquors in lab-scale has been done using sulfate reducing bacteria (SRB) isolated from sediment samples of pulp and paper mills in Vietnam. This treatment could reduce 70 - 75% of COD after three weeks. The COD removal could achieve 82 - 88% by subsequent aerobic treatment in 48 hours. COD of treated water was 80 - 90 mg/l.

The present study investigated the biocorrosion behaviour of Stainless steel 316L (SS 316L) and mild steel coupons exposed to a medium containing slime producing bacteria, Escherichia coli (E.coli).

Alternative strategies are needed in pest management to protect crops from pests. Occurrence of epiphytic lactic acid bacteria (LAB) on crop plants, especially on sites that are selected by pests, may be associated with host selection by insects. We carried out laboratory investigations as well as screen house and field experiments to understand whether epiphytic LAB occur at oviposition sites of agricultural and horticultural crops, probably modulating pest abundance by attraction or repulsion. The diversity of such epiphytic LAB associated with insect oviposition sites is discussed.
