Question

Draw cell morpholgy of red and blue bacteria. And which red or blue is vegative and which is endospore. 

The image is a Gram-stained microscopic view of bacteria from a sputum sample, likely demonstrating a mixed infection. ### Description: **Bacteria Arrangement:** - **Red Rod-Shaped Bacteria:** These are Gram-positive bacilli. They appear in clusters and chains, indicated by the orange arrow. - **Blue Spherical Bacteria:** These are Gram-negative cocci, shown as small blue dots, indicated by the blue arrow. ### Staining Technique: - **Gram Stain:** A differential staining technique used to classify bacteria into two groups: Gram-positive (red here) and Gram-negative (blue here), based on the structural differences in their cell walls. ### Educational Insights: - **Gram-Positive Bacteria:** They have a thicker peptidoglycan layer in their cell walls, retaining the crystal violet stain, which appears red when counterstained with safranin. - **Gram-Negative Bacteria:** They have a thinner peptidoglycan layer which does not retain the crystal violet stain, appearing blue after the counterstain. ### Image Credit: This image is credited to ASM MicrobeLibrary.org © Keplinger. It serves as an excellent visual aid for understanding bacterial classification and morphology.
