Helicobacter pylori is a gram-negative, micro-aerobic, spiral-shaped bacteria and which considered one of the main factors that lead to stomach disorders such as gastric atrophy, stomach cancer, chronic gastritis, and peptic ulcers. This study is carried out in Nineveh Governorate, Iraq included 325 participants, after conducting a series of tests to detect whether H. pylori infection is positive among participants, the number of infected participants were150 (48 males and 102 females), then complete Blood Counts test were done in order to investigate the relationship between the Component Blood Count and the infection of H. pylori. These results concluded that H. pylori infection is more prevalent in females, also the percentage of infection decreases ages over 60 years and children less than 15 years, the incidence of H. pylori infection increases in people blood type A, the study didn't show any effect of smoking on the increased risk of infection with H. pylori. In this study, the infected patients with H. pylori recorded an increase in WBCs equal to 24%, while lymphocyte counts didn't record any changes, RBCs were increases by 12%, some infected patients had fluctuations of increase and decrease in the level of Hb, figures were between 8% and 24%, respectively, the increase in the platelet count was 12%, and the decrease was 4%. There are significant differences in the relationship between infection with H. pylori and other factors such as; gender, age, WBCs, lymphocyte counts, RBCs, Hb, and platelet counts in the infected group at P ≤ 0.05.
