Culture-based antimicrobial susceptibility testing is a crucial method for the management of Helicobacter pylori infection . It must follow the European Committee on Antimicrobial Susceptibility Testing (EUCAST) recommendations for fastidious microaerophilic bacteria, with some possible variation especially for the medium to be used. It is recommended to test six antibiotics by diffusion using strips charged with an antibiotic gradient in order to determine the minimum inhibitory concentrations (MICs). Two of these antibiotics, clarithromycin and levofloxacin, are more important because of frequent resistance which jeopardizes the success of the treatment.

UI	MeSH Term	Description	Entries
D003470	Culture Media	Any liquid or solid preparation made specifically for the growth, storage, or transport of microorganisms or other types of cells. The variety of media that exist allow for the culturing of specific microorganisms and cell types, such as differential media, selective media, test media, and defined media. Solid media consist of liquid media that have been solidified with an agent such as AGAR or GELATIN.	Media, Culture

D016480	Helicobacter pylori	A spiral bacterium active as a human gastric pathogen. It is a gram-negative, urease-positive, curved or slightly spiral organism initially isolated in 1982 from patients with lesions of gastritis or peptic ulcers in Western Australia. Helicobacter pylori was originally classified in the genus CAMPYLOBACTER, but RNA sequencing, cellular fatty acid profiles, growth patterns, and other taxonomic characteristics indicate that the micro-organism should be included in the genus HELICOBACTER. It has been officially transferred to Helicobacter gen. nov. (see Int J Syst Bacteriol 1989 Oct;39(4):297-405).

D016481	Helicobacter Infections	Infections with organisms of the genus HELICOBACTER, particularly, in humans, HELICOBACTER PYLORI. The clinical manifestations are focused in the stomach, usually the gastric mucosa and antrum, and the upper duodenum. This infection plays a major role in the pathogenesis of type B gastritis and peptic ulcer disease.	Infections, Helicobacter,Helicobacter Infection,Infection, Helicobacter
D017291	Clarithromycin	A semisynthetic macrolide antibiotic derived from ERYTHROMYCIN that is active against a variety of microorganisms. It can inhibit PROTEIN SYNTHESIS in BACTERIA by reversibly binding to the 50S ribosomal subunits. This inhibits the translocation of aminoacyl transfer-RNA and prevents peptide chain elongation.	6-O-Methylerythromycin,A-56268,Biaxin,TE-031,A 56268,A56268,TE 031,TE031
D052978	Disk Diffusion Antimicrobial Tests	A method where a culturing surface inoculated with microbe is exposed to small disks containing known amounts of a chemical agent resulting in a zone of inhibition (usually in millimeters) of growth of the microbe corresponding to the susceptibility of the strain to the agent.

D024901	Drug Resistance, Multiple, Bacterial	The ability of bacteria to resist or to become tolerant to several structurally and functionally distinct drugs simultaneously. This resistance may be acquired through gene mutation or foreign DNA in transmissible plasmids (R FACTORS).
