Abstract

The use of synthetic antibiotics to treat bacterial infections can trigger resistance of pathogenic bacteria to antibiotics. One effort to overcome this is to explore microorganisms that produce antibacterial compounds from nature. A previous study reported isolates of Bacillus sp. AM12 from mangrove soil displayed antibacterial potential based on preliminary screening of the perpendicular streak test. This study was designed to confirm the antibacterial potential of Bacillus sp. AM12 uses chemical solvent extraction. Bacillus sp. AM12 was fermented in 100 mL liquid ISP-2 sterile and shaken at 150 rpm for 7 days. The supernatant was filtered from the cell mass using Whatman paper and extracted using 100 mL of ethyl acetate solvent (1:1, v/v) twice. The filtrate was evaporated at 40ºC until a thick, clear yellowish colored extract was obtained. The thick extract was tested for antibacterial activity using the Kirby-Bauer method against two Gram positive and two Gram negative bacterial targets. Antibacterial screening showed moderate diameter zone of inhibition of 6.72 ± 0.21 mm, 6.82 ± 0.15 mm, and 6.62 ± 0.21 mm against Staphylococcus aureus ATCC 25923, Streptococcus mutans FNCC 0405, and Klebsiella pneumoniae ATCC 70060, respectively. However, no antibacterial activity was observed against Escherichia coli ATCC 25922. Analysis of the chemical composition of ethyl acetate crude extracts using GC-MS has detected 10 different compounds, in which the 3 most dominant antibacterial compounds were Benzene, 1,2,4-Trimethyl-, Benzene, 1-ethyl-2-methyl- and 2-butoxyethyl acetate. In general, these results provide an initial description of Bacillus sp. AM12 is a potential of antibacterial producer.

Abstract

This investigation aimed to determine the prevalence and biofilm-forming potentials of bacterial uropathogenic among primary school pupils in Yola North, Adamawa State. A total of 120 clean mid-stream urine samples were collected from apparently healthy children to determine the antimicrobial susceptibility of the isolated pathogen by the Kirby and Bauer disc diffusion method while the biofilm-forming potential by the standard methods. The result showed 26 % of the samples had significant bacteria growth with the Gram-negative as the highest. The infectivity pattern among the age group showed 8-10 had the highest infectivity percentage (35%) followed by 5-7 and 11-13 with 22.5% and 20% respectively. Six bacteria pathogens were isolated which are E. coli (41.9%) which is the most prevalent isolate followed by Staphylococcus aureus (29.0%), Pseudomonas sp. (9.7%), Klebsiella sp. (9.7%), Enterobacter sp. (6.5%), Proteus sp. (3.3%). The antibiotic sensitivity test showed an alarming resistance level to nearly all the tested antibiotics showing multi-drug resistant strains. The Biofilm-forming potentials depict E. coli with the strongest potential followed by S. aureus. A high occurrence of asymptomatic UTIs and antimicrobial resistance observed poses a public health concern. Thus, routine diagnostic exercise is recommended for early detection and prompt treatment of the pathogens.

Abstract

Coffee leaves-based tea has relevance in ethno-medications due to its rich phyto-constituents-related diverse pharmacologic activities. Jonhu tisane, a typical Coffea arabica leaf decoction has no supporting scientific basis amidst reported location, processing and specie-related variations. This investigated physicochemical, antimicrobial, lethality and in-vitro antioxidant profiles of Johnu tisane by acceptable methods. Results recorded moisture (92.26 %), ash (0.65 %), unsaponified matter (1.46 mg/100 g), free fatty acid (0.56 mgKOH/g), acid value (1.12 mgKOH/g), potential hydrogen (6.85), lethal concentration (1000 ppm) and concentration-dependent antimicrobial activity. Anti-oxidation results revealed total antioxidant capacity, ferric reducing antioxidant power, nitric oxide, hydrogen peroxide and 2, 2-diphynyl-1-picrylhydrazyl scavenging activities increased concentration-dependently compared to standard. Thus, Johnu tisane demonstrated low minerals and keeping quality; requisite physicochemical mix for consumption and bioactivity; high safety margin; antimicrobial potency; and requisite anti-oxidation capacity for in-vivo antioxidant role. These provided scientific support for its ethno-medicinal uses. They underscored the need to elucidate its pharmacologically active compounds; mechanistic roles in animal models; and the impact of ash to moisture mix variation on potential hydrogen, microbial and antimicrobial activities in relation to shelf life, bioactivity and in vivo anti-oxidative roles for novel insights on preserving sample quality, safety, bioactivity and in-vivo anti-oxidative outcomes.

Abstract

Sepsis, a severe medical condition, signifies the systemic immune response to infection, often leading to organ dysfunction and mortality. Escherichia coli is a significant contributor to sepsis cases, particularly in gastrointestinal disorders. This study aimed to investigate the histopathological changes in the gastric tissue of mice induced by Escherichia coli infection and evaluate the protective effects of kentut leaf extract (Paederia foetida L.). Histopathological analysis revealed distinct alterations in the gastric tissue among different treatment groups. While normal mouse treatment showed no significant changes, negative control (K-) and positive control (K+) groups exhibited inflammation and hyperemia of the gastric mucosa, characterized by necrosis, degeneration, and inflammatory cell infiltration. Treatment with kentut leaf extract (P1, P2, and P3) resulted in milder inflammation compared to controls, indicating a protective effect against gastric mucosal damage induced by Escherichia coli infection. This protective mechanism is attributed to the anti-inflammatory properties of saponins, flavonoids, and essential oils present in kentut leaf extract. These findings underscore the potential therapeutic benefits of kentut leaf extract in mitigating gastric mucosal injury associated with bacterial infection.

Abstract

Diabetes is a health burden in various countries, one of these countries, is also Indonesia. Dragon fruit peel is an alternative diabetes therapy that has been widely studied. Therefore, this study aimed to investigate an antidiabetic effect of dragon fruit peel methanol extract on alloxan-induced diabetic male Wistar rats. This experimental study used twenty-five male Wistar rats induced by alloxan injection. After 48 hours, all rats were grouped into five different groups, including control (0.5% SCMC), standard (Metformin), Dragon Fruit Peel Methanol Extract-1 (500 mg/kg BW), 2 (750 mg/kg BW), and 3 (1,000 mg/kg BW). These treatments were given for two weeks. After that, all rats were dissected to obtain the pancreas. The results showed that dragon fruit peel methanol extract significantly decreased blood glucose levels after the 7th and 14th days (P value <0.05). In addition, pancreatic histology showed a decrease in the extract dose followed by a smaller size of the pancreatic Langerhans islet. The lowest dose of the extract showed a similar size of pancreatic Langerhans islet to the control group with an atrophic pancreatic Langerhans islet. Therefore, it can be concluded that dragon fruit peel extract can significantly decrease blood glucose levels and improve the structure of pancreatic Langerhans islet at higher doses.

Abstract

Cyclodextrin glycosyltransferase (CGTase) is an extracellular enzyme produced by several microorganisms, particularly bacteria, that converts starch into cyclodextrin (CD). CD has various applications in fields such as food, textiles, pharmaceuticals, chemistry, and biotechnology. The objective of this study was to isolate b-CGTase-producing bacteria from soil in a potato plantation located in Kerinci, and to conduct their characterization. Screening was conducted using Horikoshi agar media with phenolphthalein and methyl orange color indicators. The results indicated that one isolate, coded CK-2, produced the optimum b-CGTase enzyme when incubated for 30 hours at 37 ºC and pH 10. The CGTase enzyme converted starch to CD when incubated for 60 minutes at 37 ºC and pH 7. The CK-2 isolate was identified as monobacilli Gram-positive bacteria, having spores, positive in the catalase test, and motile. The study concluded that the bacteria producing b-CGTase enzyme are found in the soil of potato plantations in Kerinci, which is believed to originate from the genus Bacillus sp.

Abstract

Newcastle disease is a highly contagious viral infection affecting poultry and wild birds. The causative agent is Avian paramyxovirus 1 (APMV-1), causing significant economic losses despite vaccination efforts due to its high mortality rate. Hibiscus sabdariffa was identified at Modibbo Adama University Yola, and laboratory assays were performed at the National Veterinary Research Institute Vom. The study explores the antiviral effects of extracts from H. sabdariffa calyx against a virulent strain of Newcastle Disease Virus (NDV) using embryonated chicken eggs (ECE). Standard methods were employed for cytotoxicity assay, embryo infective dose 50 (EID50) determination, and therapeutic antiviral assays. Methanol was used for extraction and phytochemical analysis, revealing various bioactive compounds like cardiac glycosides, alkaloids, flavonoids, terpenes, and phenols. Toxicity assay showed cytotoxicity at concentrations over 25 mg/ml, but therapeutic antiviral assays demonstrated virus replication inhibition at concentrations as low as 5 mg/ml. These findings suggest the potential of H. sabdariffa calyx extracts as safe and effective treatments for NDV, with promising therapeutic antiviral properties. Further pharmaceutical research is recommended to explore their use in developing novel Newcastle Disease treatments.
