Antimicrobial susceptibility testing in petri dish. Microbiologist check Antibiotic resistance of bacteria
Lactose-negative biofilm-forming Enterobacter cloacae, resistant to multiple drugs. Enterobacter cloacae is a member of the normal gut flora. These bacteria are responsable for many hospital-acquired infections for which the mortality rate is generally high.

Close-up shot of a petri dish for checking an antibiotic in the laboratory.
Cultivation of bacteria of the species Escherichia coli in selective medium
Protein molecules form crystals by arranging themselves in a regular pattern. Their shape is like a transparent gem and attracts many scientists. Protein crystal structures are an important area of research that can provide clues for drug discovery. This image is reminiscent of a protein crystallising in solution.\nThis image was not created by AI.
Staphylococcus aureus bacterial colonies
Life-threatening infections are on the rise due to drug-resistant bacteria. Carbapenemase-producing organisms (CPO) are bacteria that have become resistant to a group of antibiotics known as carbapenems. CPO are emerging pathogens world wide.
Mannitol Salt Phenol Red Agar (Synonym: Chapman Agar) is a modified microbiological medium for detecting pathogenic staphylococci in food-stuffs.
