Isolation and Characterisation of Essential oils of Mango (M. indica) Leave
Get PDFThis research work aimed at isolation and characterisation of essential oils of Mangifera. indica (M. indica) leaves. Phytochemical screening was carried out to determine the bioactive components present in the leaf sample as well as the antimicrobial activity of the crude ethanolic extract. The percentage yield of essential oils (colourless) of the leaf was 0.19%. The phytochemical screening revealed the presence of alkaloid, glycoside, flavonoid, saponin and tannin.  Steroids was absent in the extract. The antimicrobial evaluation of the essential oil of M. indica leaf revealed a significant activity (zone of inhibition). The percentage (%) of Diphenyl picryl hydrazine (DPPH) scavenged of antioxidant activities for the essential oils of M. indica at different concentration of 5µl, 10µl, 25µl and 100 µl showed a significant antioxidant activity. In concluded results, it’s clearly observed that, when the concentration of both ethanolic extract and essential oils leaf sample increases, the antimicrobial and antioxidant properties increases when compared to the standard (Amoxicillin) and that of essential oils has a significant property than other extracts. Considering the results of phytochemical screening, it’s also a potential source of cost-effective food supplements, nutritive ingredients and antibacterial agent for improving human health and curing acute and chronic diseases. The GC-MS analysis of the essential oils for the leaf sample revealed fifty two (52) different chemical compounds which include Alloaromadendrene, Humulene, Bicyclo[4,4,0]dec-1-ene, 2-isopropyl-5-methyl-9-methylene, Bicyclo[7.2.0]undec-4-ene,4,11,11,-trimethyl 8-methylene-,[1R-(1R*,4Z,9S*)]

Detection of Antibacterial Susceptible Salmonella spp. in Cured Beef with Different Shelf-Life Expectancy
Get PDFMeat is currently one of the food products with the highest demand ever since 1980, where demand has reached 24.8 kg per year per person as of 2020. With high demand comes intensive farming which causes overuse of antimicrobials for both therapeutic and non-therapeutic reasons, allowing more antimicrobial resistant (AMR) strains of bacteria to occur. In the case of meat products, salmonella is considered one of the more commonly occurring bacteria found in raw meat products. However, with meat’s short shelf-life expectancy, the likeliness of consumers suffering from salmonellosis increases. Thus, preservation methods have been implemented to reduce this likeliness, primarily through curing beef. Although curing may reduce the likeliness of excessive microbial growth, AMR salmonella has been detected in cured beef samples. The scope of this research determines whether there is Salmonella spp. within the cured beef samples, conduct AMR (azithromycin, ciprofloxacin, and ceftriaxone) analysis of the Salmonella spp. isolated from the cured beef samples and enumeration was conducted. The longer the shelf-life expectancy of cured beef samples, the lower the overall CFU/mL per sample was (control: 17,800,000 CFU/mL, >1 year: 0 CFU/mL). It was also discovered that Salmonella spp. has potential resistance towards ciprofloxacin (33.33% intermediate) and susceptibility towards azithromycin and ceftriaxone (100.00% sensitive). This research implies the agricultural industry and safety for consumers of cured beef products with different shelf-life expectancies

Nanotechnology-Based Vaccines
Get PDFSeveral new infectious diseases have developed in recent years, and a few old ones that were formerly thought to pose no threat to humans have made a comeback. Millions of fatalities are attributed to these illnesses together, having a significant negative influence on the worldwide socioeconomic and healthcare sectors. The lack of appropriate medications for many of these disorders is one of the biggest obstacles to treating them. Yet, several of the most common diseases currently have no vaccinations that are reliable. The ideal vaccine should have several key characteristics, including safety, stability, and the capacity to induce a sufficient and long-lasting immune response with a minimal number of doses. To induce protective immunity against illnesses, different generation vaccines are employed, including attenuated or dead entire organisms (first generation), subunits (second generation), and RNA or DNA vaccines (third generation). To get beyond these obstacles, a reliable vaccination delivery mechanism is needed, one that not only gets the vaccine molecules to the target region where they can trigger long-lasting immune responses but also has few side effects and uses fewer doses. Only a few hundred atoms make up the majority of nanoparticles. Nanoparticles have a relatively significant surface area-to-volume ratio because of their extremely small size. Nanoparticles can have surprising optical, physical, and chemical properties due to this property. Nanotechnology has many benefits for the creation of vaccines for the next generation. A delivery strategy based on nanocarriers can shield vaccines from early deterioration, increase stability, have high adjuvant qualities, and can help with the targeted distribution of an immunogen. The researcher conducts an examination of articles that are in accordance with the issue to be studied. Articles used in the literature review are obtained through the database of international journal providers through PubMed, we investigated clinical studies and discussed what happened in these clinical studies and the extent of the effectiveness of Nanoparticle-Based Vaccines. In order to achieve effective vaccine distribution and generate the required host immunity against infectious diseases, this review article focuses on the applications of nanocarrier-based vaccine formulations and the methodologies utilized for functionalizing nanoparticles
