Fig. 3From: Genetic variants of Helicobacter pylori type IV secretion system components CagL and CagI and their association with clinical outcomesPhylogenetic tree of 40 clinical isolates based on CagL and CagI sequences. Neighbor-Joining tree analysis of concatenated CagL (a, b) and CagI (c, d) sequences for 40 isolates is shown. Each Neighbor-Joining method tree was made using MEGA7 software. Open square, open circle, filled circle, and filled triangle symbols correspond to isolates derived from gastric cancer patients, Japanese isolates, Chinese isolates, and Vietnamese isolates, respectivelyBack to article page
