A cell is expоsed tо cоld thаt decreаses membrаne fluidity. Which macromolecule most directly help maintain fluidity under these conditions?
The Scenаriо: A 24-yeаr-оld pаtient presents tо the urgent care clinic with severe abdominal cramps, a low-grade fever, and persistent diarrhea after attending a backyard barbecue 48 hours ago. The physician suspects a bacterial pathogen and orders a stool culture. Laboratory Results: Gram Stain & Morphology: Under the microscope, the lab technician observes Gram-negative, rod-shaped bacteria. Biochemical Plating: * MacConkey Agar: Growth is observed, but the colonies are colorless (non-lactose fermenting). Hektoen Enteric (HE) Agar: The colonies appear blue-green with a distinct black center, indicating the production of Hydrogen Sulfide (H2S). Species Morphology Gram Stain Key Agar/Biochemical Reactions Escherichia coli Rod Negative MacConkey: Bright pink (Lactose +) Salmonella enterica Rod Negative HE Agar: Blue-green with black centers ($H_2S$ +) Staphylococcus aureus Cocci (Clusters) Positive MSA: Yellow (Mannitol fermenter) Streptococcus pyogenes Cocci (Chains) Positive Blood Agar: Clear zone (Beta-hemolysis) Pseudomonas aeruginosa Rod Negative Nutrient Agar: Produces blue-green pigment Bacillus subtilis Rod Positive Starch Agar: Clearing around growth (Amylase +) Vibrio cholerae Curved Rod Negative TCBS Agar: Large yellow colonies Shigella flexneri Rod Negative HE Agar: Green colonies (No $H_2S$); MacConkey: Colorless Staphylococcus epidermidis Cocci (Clusters) Positive MSA: Pink/Red (Non-mannitol fermenter) Klebsiella pneumoniae Rod Negative MacConkey: Pink & Mucoid (Lactose +) Based on the Gram stain and the black-centered colonies on the HE agar, identify the most likely genus of bacteria causing the infection. Cite your evidence from the chart above.
