The patients were from different regions of Nigeria: Jos, North, Benue, West and East and the blood donors were from Jos. Sera were assayed for anti-CagA antibodies using Helicobacter p120, CagA ELISA (Viva Diagnostika, H\u00fcrth, Germany). Anti-CagA antibodies were detected in 104 (94.5%) patients and in 61 (95.3%) blood donors ( P=1.0). Patients from the Benue region presented a lower frequency of anti-CagA antibodies than patients from the other regions ( P=0.0004). When the subjects were stratified by age, a significant increase in IgG concentration was observed among the men ( P=0.03) but not among the women ( P=0.57) or among the blood donors ( P=0.83). In conclusion, similarly to Asian countries, CagA-positive H. pylori infection is highly frequent in Nigeria.<\/jats:p>","DOI":"10.1177\/004947550103100310","type":"journal-article","created":{"date-parts":[[2017,1,13]],"date-time":"2017-01-13T17:07:34Z","timestamp":1484327254000},"page":"147-149","source":"Crossref","is-referenced-by-count":5,"title":["Anti-CagA
