Detection of Helicobacter pylori glmM gene in bovine milk using Nested polymerase chain reaction

AIM: The aim was to detect the glmM gene of Helicobacter pylori (H. pylori) in cow’s milk from different dairy farms in Khartoum State using Nested polymerase chain reaction (PCR). MATERIALS AND METHODS: A total of 50 milk samples were collected from different dairy farms in Khartoum State (13 from Khartoum, 24 Khartoum North, and 13 from Omdurman Provinces). RESULTS: The generated results showed that 11/50 (22%) were harboring the investigated H. pylori glmM gene in Khartoum State (1/13 [7.7%] Khartoum, 9/24 [37.5%] Khartoum North, and 1/13 [7.7%] Omdurman provinces, respectively). CONCLUSION: To the best of our knowledge, this was the first report on the detection of H. pylori glmM gene in cattle milk in Khartoum State. Nonetheless, the high percentages of H. pylori DNA detection in milk opened new avenues toward exploring the risk of human infection with H. pylori through the consumption of raw milk.
