Chemistry is traditionally divided into organic and inorganic chemistry. Safety of Pyridazin-4-amine, The former is the study of compounds containing at least one carbon-hydrogen bonds.In a patent，Which mentioned a new discovery about 20744-39-2
This study was done to assess the proliferation bacterial and susceptibility resistance antibiotic pattern of (UTIs) pathogens. For identification of mid stream urine samples 40causative microbial agents from 10-50 years clinical sample with clinical symptoms to be UTI were collected and appropriate biochemical tests. These samples were collected from Teaching Laboratories Center in Baghdad. The antimicrobial sensitivity test was carried out by Well Diffusion Assay technique using Muller- Hinton agar. Overall female only the most isolates were Escherichia coli with average rate of 50% followed by Enter obacter spp. (12%). Whereas, Klebsiella, Pseudomonas Aeruginosa and Enter occurs faecalis showed frequency rate of 9% for each. (Family Solanaceae) species Capsicum frutescent L. Usually used most of the spice, (red peppers) is also increased benefits with multiple healths human. In the study, yield extract included constituents phytochemical of (n-hexane, chloroform, ethyl acetate, acetone and methanol) extracts of dried fruit. Antibacterial activity in vitro of extracts was determined by WADA method gram positive bacteria (Staphylococcus Aureus) and gram negative bacteria (Escherichia coli, Pseudomonas Aeruginosa, Klebsiella pneumonia and Enterococcus faecalis). MIC evaluated by two fold serial broth tube dilution method ranged between 0.312 to 5 mg/mL.
