Background And Objective: is the most common etiological agent of UTI and accounts for more then 100, 0000 hospitalization annually. The objective of this study was to investigate the antimicrobial activity of aqueous and ethanolic extracts of against from urinary tract infection patients.
Methods: Urine samples of forty four suspected patients from Tertiary Care Hospital Faisalabad were used in this study. Ethanolic and aqueous extracts of (PV), a medicinal plant was evaluated for its ability to inhibit the growth of 38 resistant isolates of strains and compared to Ciprofloxacin, Ofloxacin, Cefixime and Tobramycin by well diffusion method. Minimum inhibitory concentration was measured by using broth micro dilution method.
Results: PV showed antibacterial activity against strains, however Tobramycin at 10 microgram (10μg) inhibited the resistant to a greater extent as compared to other antibiotics and was resistant to twice less number of strains, about 82% of isolates have MDR pattern.
Conclusion: Ciprofloxacin has more efficacy than PV and no synergistic effect with extracts of PV. Cefixime is least efficacious against resistant , however it has synergistic effect with extracts of PV.

( ) is the world's most deadly infectious pathogen and new drugs are urgently required to combat the emergence of multi-(MDR) and extensively-(XDR) drug resistant strains. The bacterium specifically upregulates sterol uptake pathways in infected macrophages and the metabolism of host-derived cholesterol is essential for long-term survival Here, we report the development of antitubercular small molecules that inhibit the cholesterol oxidases CYP125 and CYP142, which catalyze the initial step of cholesterol metabolism. An efficient biophysical fragment screen was used to characterize the structure-activity relationships of CYP125 and CYP142, and identify a non-azole small molecule that can bind to the heme cofactor of both enzymes.

Extraintestinal (ExPEC), known to be the most common instigators of urinary tract infections (UTIs), represent such global threat. Novel strategies for more efficient treatments are therefore desperately needed.

Dental caries is a highly prevalent chronic condition globally. In recent years, scientists have turned to natural compounds such as plant extracts as an alternative to address concerns related to biofilm-mediated disease transmission, increasing bacterial resistance, and the adverse impacts of antibiotics. Consequently, this study investigated the antimicrobial properties of ethanolic, hydroethanolic, and aqueous extracts of L.
