The study shows that metabolic mutations in Pseudomonas aeruginosa lead to pyruvate secretion, which reduces oxidative stress, dampens immune responses, promoting bacterial survival and persistence in...

Abstract. Antimicrobial resistance poses a major threat to global human health. The emergence and spread of antimicrobial resistance is usually studied for

P aeruginosa is found in 11.6% of diabetic foot infection cultures from hot, humid climates.

Pseudomonas aeruginosa is the most frequently isolated pathogen in acute otitis externa (AOE), with ototopical antibiotics being the mainstay of treat…

The structure of a type IV pilin from a human-pathogenic strain of P. aeruginosa was solved to 1.3 Å resolution using molecular replacement with an AlphaFold-generated search model. It is the first structure from this group of pilins to be discussed and reveals the structural differences that result in functional diversity between closely related type IV pili.

Carefully read each clinical scenario and identify the key features: patient history, risk factors, and site of infection. Then, match each scenario with the most likely causative organism. Focus on patterns like prosthetic device infections, dental hygiene, cystic fibrosis lung infections, contact lens–related eye infections, and recurrent pediatric ear infections. This approach improves accuracy in microbiology and clinical reasoning exercises.

Carefully read the microbial characteristics and match each organism with its typical colony appearance or pigment. Focus on distinctive colors produced by bacterial species, which are key in microbiology identification. Drag and drop the correct description into each box to reinforce learning and retention.

The European Committee on Antimicrobial Susceptibility Testing (EUCAST) changed the definition of the ‘intermediate’ (I) category in 2019, now defined…

For decades, the study of bacterial persistence has relied heavily on Escherichia coli as the primary model organism. Microbiologists have largely operated under the assumption that the mechanisms gov...
