Research ArticleOpen accessEvery word in the titleAssay for Rapid Screening of Phytochemicals as Antimicrobial AgentsGhosh Saurav, Indranil Mukherjee, Ashoke Ranjan Thakur, Shaon Ray ChaudhuriThe present study aims to develop a rapid method for antibiotic sensitivity detection and screening of natural products for antimicrobial activity. The dimension of WBC in blood film was found to get altered when seeded with bacteria and monitored under light microscope. The shrinkage was prevented in response to antibiotic treatment and validated using statistical analysis (two sample one tailed … …American Journal of Biochemistry and Biotechnology, Vol. 9, Issue 1 · 18 Mar 2013 · 8,303 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAcaricidal Activity of Azadirachta indica (Neem Tree) and Carica papaya (Papaya) Leaf Extracts against Rhipicephalus sanguineus (Dog Ticks) Using Spray MethodAlfredo Vita Corpuz, Carmela Montoya Florentino, Paul Erman Tabuloc Quilana et al.Ticks pose a serious threat to dogs, with synthetic acaricides leading to environmental impact and resistance concerns. While Azadirachta indica and Carica papaya have shown acaricidal potential against Rhipicephalus sanguineus, their efficacy against dog ticks has not been thoroughly investigated. This study determined the acaricidal activity of A. indica and C. papaya leaf extract against R. sanguineus, both individually and … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 22 Apr 2025 · 8,409 accessesView PDF Cite

Research ArticleOpen accessIn the keywordsAntibacterial Activity of Lotus Leaves (Nelumbo Nucifera) Against Food-Borne PathogensJianxin Chen, Changyin Wang, Xiaotian Chen et al.The antibacterial activity of different solvent extracts from lotus leaves against four food-borne bacteria (Escherichiacoli, Salmonellatyphimurium, Staphyloccocusaureus, Bacillussubtilis) was analyzed by agar diffusion method and the ethanol extract of the plant was found to have the highest antimicrobial activity with the diameter of inhibition zones ranging from 17.2 to 17.8 mm. Then the ethanol extract of lotus leaves were further … …American Journal of Biochemistry and Biotechnology, Vol. 11, Issue 1 · 18 Nov 2014 · 10,152 accessesView PDF Cite

Review ArticleOpen accessIn the abstractMultidrug Resistant Microorganisms (MDR) and Biofilm Producers: A Challenge for Hospital Infectious ControlDaniel Lucio, Elizabeth Proaño, Alberto Bustillos et al.Antimicrobial Resistance (AMR) now represents a major threat to contemporary health care, especially in hospitals, where repeated antimicrobial exposure selects for and facilitates the dissemination of Multidrug-Resistant (MDR) microorganisms. Biofilm growth adds another layer of persistence by increasing microbial tolerance, supporting long-term colonization of medical devices, and worsening clinical and economic outcomes. This narrative review synthesizes evidence on MDR biofilm-forming … …American Journal of Biochemistry and Biotechnology, Vol. 22, Issue 3 · 12 Sep 2026 · 774 accessesView PDF Cite

Research ArticleOpen accessIn the abstractStudy of Ageratum conyzoides L. (Asteraceae) Phytochemical Composition as Quorum-sensing Inhibitors to Combat Antibiotic-resistant Bacterial InfectionsEli Compaoré, Lassané Ouedraogo, Ablassé Rouamba et al.The rise of antibiotic-resistant bacterial infections has intensified the search for plant-derived quorum-sensing (QS) inhibitors as alternative therapeutic strategies. Ageratum conyzoides L. has a long history of traditional use as an antimicrobial agent against multidrug-resistant pathogens, yet the phytochemical basis of its QS-inhibitory activity remains incompletely characterized. This study aimed to investigate the phytochemical composition of A. conyzoides and evaluate … …OnLine Journal of Biological Sciences, Vol. 26, Issue 1 · 3 Apr 2026 · 1,772 accessesView PDF Cite

Research ArticleOpen accessIn the abstractLarvicidal Activity of Spondias purpurea (Sineguelas) Leaf and Hylocereus costaricensis (Dragon Fruit) Stem Extracts Against Aedes aegyptiAlfredo V. Corpuz, Nigell Mikhail A. Gallardo, Ace Danielle C. AveroThe study determined the larvicidal activity of the different concentrations of Spondias purpurea and Hylocereus costaricensis extracts by measuring percent mortality in Aedes aegypti larvae, a primary vector of dengue and other arboviral diseases. The hypothesis proposed that combining both extracts would yield greater larvicidal activity due to potential synergistic interactions. Ethanolic extraction was used to isolate a wide array … …OnLine Journal of Biological Sciences, Vol. 25, Issue 3 · 20 Nov 2025 · 2,417 accessesView PDF Cite

Research ArticleOpen accessIn the abstractPhytochemical Content and Antioxidant Potential of Leaf Extract Berchermia discolour (Munie Tree) For Goats in The Limpopo Province, South AfricaMosima Molepo, Grace Manyelo, Busisiwe GunyaThe study aims to investigate the phytochemical content and antioxidant potential of leaf extract Berchermia discolour (Munie tree) for goats. Plant leaves were ground, and their powder was mixed with reagents and chemicals to attain the concentration level of phytochemicals and other bioactive compounds found in these plant's properties. Most of the phytoconstituents were present (shown by the change of … …OnLine Journal of Biological Sciences, Vol. 25, Issue 2 · 29 Mar 2025 · 5,357 accessesView PDF Cite
