The blood pressure is 12080 mm Hg, heart rate is 78min, respiratory rate is 13min, and temperature is 37.0C 98.6F. The physical examination is within normal limits. A urine culture grew the pathogens pictured. The presence of which of the following factors specifically allows this pathogen to cause urinary tract infections?? A: P-fimbriae, B: K-capsule, C: Heat-labile toxin, D: Heat-stable toxin, E: Hemolysin,  <response>: This is a medical question asking about the pathogenesis of a urinary tract infection caused by a specific bacterium shown in the image. Based on the image, the bacterium appears to be E. coli. E. coli is a common cause of UTIs. The question asks about a specific virulence factor that allows E. coli to cause UTIs. To answer this, we need to consider the key virulence factors of E. coli that promote colonization and infection of the urinary tract. The choices include various toxins and surface structures like fimbriae and capsule. Fimbriae help E. coli adhere to uroepithelial cells, which is critical for colonization and infection. The other choices do not play a major role in E. coli UTIs.A: P-fimbriae
