Antimicrobial activity of the aerial parts of the Elytraria acaulis a stem less perennial herb of Acantheceae family has been carried out in the present study. Extracts of the aerial parts of the plant (Stem & Leaves) were prepared in different organic solvents such as n-Hexane, Ethanol, Methanol and Ethyl acetate. All the extracts were analyzed for antimicrobial properties against various pathogenic bacterial infections (Escherichia coli, Klebsiella Species, and Salmonella Typhi). Amongst all the extracts, methanolic extract exhibited significant antimicrobial activity. The crude methanol extracts of leaves showed good inhibitory effects against pathogens. Hence further studies on this plant will enable elucidation of its therapeutic properties and medicinal applications.
ABSTRACT- The present study was planned to study the antimicrobial activity of different plant extract against selected microorganisms. The plants used in the present study were Ocimum sanctum (Tulsi), Withania somnifera (Ashwgandha), Santalum album (Chandan), Aloe vera (Aloe barbadensis), and shatavari (Asparagus racemosus). The extract from the leaves of these plants (are) used in malaria, bronchitis, gastric disorders, cough, cold etc. To test efficiency of some common plants extract against E. coli, Salmonella typhi, Proteus vulgaris, Staphylococcus aureus. Contrary to the synthetic drugs, antimicrobials of plant origin are not associated with many side effects and have an enormous therapeutic potential to heal many infectious diseases. The present investigation is therefore, undertaken to test the efficiency of some of the common plant extracts against some plants and human pathogens, i.e. E. coli and S. aureus. In this project work, we studied the different parts of medicinal plants of Latur, Osmanabad region used for curing different type of diseases specially skin diseases. Some plants have active components which show antimicrobial activity. These Herbal plants are beneficial to human being in therapeutic practice. Skin diseases are difficult conditions to live with, to save the very least. Though some skin diseases may cause minimal discomfort, the visual effects of the conditions can cause significant self esteem and confidence issues. The majority of skin diseases cause scarring or disfigurement. Skin diseases run the gambit from barely noticeable to fatal.

This proposal aims to isolate and identify the active compounds in five medicinal plants - ginger, hierba buena, poleo, cinnamon, and clavo - that give them antibacterial properties against E. coli, Enterococcus faecalis, and Salmonella enteriditis. The plants will be extracted and purified through chromatography techniques. The isolated compounds will then be tested using disk diffusion assays and minimum inhibitory concentration assays to determine which have the strongest inhibitory effects on the bacteria. Identifying these antibacterial compounds could contribute to the development of natural bactericides and promote further research on medicinal plant compounds.

In vitro controlling of selected human diarrhea causing bacteria by clove ext...Open Access Research Paper
Antibacterial activity of clove extracts (Syzygium aromaticum L.) was proven against five diarrhea causing bacteria. This was further confirmed when compared with commonly used three commercial antibiotics (ciprofloxacin, tetracycline and erythromycin) as a positive control. Significant differences (P<0.0001) were observed in the effect of the antimicrobial agents (clove extracts and antibiotics), and in the sensitivities of the bacterial species (P<0.0001) to the antimicrobial agents. Clove extracts had significant (P<0.001) activity with the acetone extract demonstrating highest activity followed by antibiotics and other extracts against tested bacteria. The zone of inhibition of clove extracts was ranged from 7.33 to 12.00 mm whereas in antibiotics, it was 0.00 to 11.67 mm. Of all the bacteria, Salmonella typhimurium was the most susceptible against all of the extracts as well as concentrations of clove, while low MIC (180 mgml-1) and MBC (680 mgml-1) of the extracts were observed against Shigella dysenteriae. Consequently, clove has a significant antidiarrheal activity and it could be used as an effective antibacterial agent, alternative to the use of antibiotics.

Antibacterial Activity of Stem Bark Extracts of Oroxylum indicum an Endangere...IOSR Journals
The document summarizes a study on the antibacterial activity of stem bark extracts of Oroxylum indicum, an endangered medicinal plant, against four bacterial strains. The aqueous extracts of the stem bark were tested using the well diffusion method. Results found that extracts showed inhibitory activity against all bacterial strains tested, with the highest activity observed against Bacillus subtilis at a 1:1 extract concentration. This provides evidence that O. indicum may be a potential source of antimicrobial agents and suggests further investigation is needed to identify active compounds responsible for the antibacterial effects.
This study investigated the antimicrobial activity of ethanol and chloroform extracts of Spirulina platensis against clinical isolates of Salmonella enterica serovar Typhi and Paratyphi. The ethanol extract showed variable zones of inhibition against the isolates ranging from 9.5-16 mm for S. Typhi and 9.7-14 mm for S. Paratyphi. However, the chloroform extract did not show any inhibitory effect. While the zones of inhibition were smaller than the antibiotic ciprofloxacin, this study provides promising evidence for developing a natural treatment for infections caused by these Salmonella serovars using S. platensis extracts.
This study evaluated the antibacterial activity of Moringa oleifera leaf extracts against selected bacterial pathogens. Phytochemical analysis revealed the presence of alkaloids, flavonoids and saponins in the chloroform and aqueous extracts. The chloroform extract showed the highest inhibitory activity against E. coli, S. typhi and P. aeruginosa. The minimum inhibitory concentration ranged from 10-20mg/ml while the minimum bactericidal concentration ranged from 20-40mg/ml. The results suggest that M. oleifera leaf extracts have antibacterial properties and could be further explored as potential antibacterial agents.
This document summarizes a study that analyzed the antibacterial properties of Moringa oleifera extracts against Proteus mirabilis bacteria known to cause urinary tract infections. Leaf extracts from M. oleifera were tested against 63 clinical P. mirabilis isolates and a reference strain.

Four species of plants were tested for antimicrobial properties. The plants included the Pomegranate, Punica granatum L, both organic and inorganic; Echinacea, Echinacea purpurea; and the Eastern White Spruce, Picea glauca. Out of the four plants the best results were seen with the Pomegranate plant. Negligible differences were evident between the organic and inorganic fruit, the zones of inhibition were almost identical. The organisms, which the plants were tested against included: Staphylococcus aureus, Pseudomonas aeruginosa, Escherichia coli and Candida albicans. The plants were dried and soaked in methanol. The methanol was evaporated through rotoevaporation technique. The crude products of plants were tested by bioassay. The pomegranate stunted the growth of S. aureus, P. aeruginosa and C. albicans. Next, column chromatography was performed to obtain different fractions of the Pomegranate compounds through the use of various solvent systems. The second bioassay on Punica granatum, tested second and fourth methanol fractions. This time, only S. aureus and C. albicans’ growth were inhibited by the pomegranate.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.
