An Ethnobotanical, Phytochemical Analysis, Antimicrobial and Biological Studies of Pulicaria crispa as a Graze Promising Shrub.

Due to the global issue of antimicrobial resistance, one of the most significant challenges in microbiological research is to develop a replacement antibiotic with minimal adverse effects. The wild shrub Pulicaria crispa (gethgath) has been traditionally used for camel and ruminant grazing. While prior research has demonstrated its antimicrobial properties against human diseases, no investigations have been conducted on its efficacy against animal pathogens. The objective of this study is to explore the ethnobotanical, phytochemical, antioxidant, anticancer, and antimicrobial activity of Pulicaria crispa aqueous and solvent extracts against a range of standard and animal pathogens. All of the extracts demonstrated antimicrobial, antioxidant, and anticancer properties, containing bioactive compounds. Notably, the ethyl acetate extract of P. crispa exhibited the strongest antimicrobial activity against tested Gram-positive and Gram-negative bacteria and fungi. The chloroform fraction displayed the highest antioxidant activity. Additionally, the ethyl acetate fraction showed promising anticancer activity against breast (MCF-7) and lung (A549) cancer cells. These findings confirm that Pulicaria crispa is a valuable shrub with potential applications as a natural alternative for antimicrobial, antioxidant, and anticancer treatments in both human and veterinary medicine.

Ethnobotanical, phytochemical and antimicrobial activity of Halexylon salicornicum (Ramth) as a graze and promising shrub against selected animal microbes.

Folk medicine, including plants, has been utilized for humans and animals since the dawn of civilization. Because of the widespread problem of antimicrobial resistance around the world, one of the mainly significant challenges in microbiological research is to achieve a replacement antibiotic with the fewest adverse effects. Camel and ruminant grazing were provided by the wild shrub Halexylon salicornicum (Ramth). However, despite prior research demonstrating its antimicrobial action against human diseases, no investigations on its antimicrobial activity against animal pathogens have been conducted to far. The goal of this study is to investigate whether Halexylon salicornicum aqueous and solvent extracts have antimicrobial activity on a variety of animal pathogens isolated from cattle and poultry using the agar well diffusion method (Enterococcus faecium, Shigella flexneri, Bacillus Cereus, Klebsiella pneumoniae, Staphylococcus aureus, Escherichia coli, Streptococcus pyogens, Pseudomonas aerogenes, Salmonella typhimurium, and Candida albicans) moreover it's ethnobotanical and phytochemical. All of the extracts tested had antimicrobial efficacy against tested strains and included bioactive chemicals, particularly the acetone extract, had the highest antibacterial activity. As a result, it can be stated that Halexylon salicornicum is a promising important shrub that might be used as a natural antimicrobial alternative for animals or as a food additive.
