Gram Staining Practical in Microbiology | Gram Positive & Gram Negative Bacteria| Complete Procedure

Gram Staining Practical in Microbiology 🔬 | Gram Positive & Gram Negative Bacteria In this video, you will learn the complete Gram Staining procedure step by step, including smear preparation, heat fixation, Crystal Violet, Gram’s Iodine, decolorization and Safranin counterstaining. Gram staining is one of the most important practical techniques in microbiology used to differentiate Gram-positive and Gram-negative bacteria based on their staining characteristics. morphology of bacteria and fungus. In this practical video we demonstrate: 🔬 Direct clinical sample smear preparation 🔬 Culture colony smear preparation 🔬 Heat fixation 🔬 Crystal Violet – Primary Stain 🔬 Gram’s Iodine – Mordant 🔬 Decolorizer – Critical Differentiation Step 🔬 Safranin – Counterstain 🔬 Microscopic examination under 100X oil immersion 🔬 Gram-positive bacteria – Purple/Violet 🔬 Gram-negative bacteria – Pink/Red You will also understand WHY Gram-positive bacteria appear purple and WHY Gram-negative bacteria appear pink after Gram staining. This video is useful for: • Medical Laboratory Technology students • BMLT / DMLT students • Microbiology students • Lab Technician exam preparation • Medical laboratory professionals • MBBS and other medical students studying microbiology practicals Topics covered: Gram staining practical Gram staining procedure Gram stain microbiology Gram positive and gram negative bacteria Bacterial morphology Microbiology practical Microbiology laboratory techniques Gram staining steps Crystal violet Gram iodine Decolorizer Safranin 100X oil immersion microscopy If you found this practical useful, subscribe to MedicalInformationjay for more Medical Laboratory, Microbiology, Hematology, Pathology and Biochemistry practical videos. #GramStaining #Microbiology #GramPositive
