Quadrant Streaking It is the most commonly used and the most preferred method where four equal-sized sections of the agar plate are streaked. It is also referred to as the “four-quadrant streak” or “four sectors” or “four-way streak” method. In this method, each plate is divided into four equal sectors and each adjacent sector is streaked sequentially. The sector which is streaked first is called the first sector or the first quadrant, and it has the highest concentration of inoculum. Gradually

Abhay Mishra | Academic Advisor on Instagram: "Follow @thatcoolprofessor 🎖️How many streaking methods do you actually know? 👀🧫 Most people stop at the quadrant streak, but microbiologists have turned this into a full-blown art form! 🎨 There’s the T-streak, continuous streak, radiant streak, parallel streak, three-sector, four-quadrant, zig-zag, and even cross-streak used for testing antibiotic-producing microbes like Actinomycetes! 🔬 Each method has one goal — to isolate a single pure colon
