Detection of Helicobacter pylori (H. pylori) in resource limited area: a cross-sectional study.
Article in BMC infectious diseases, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundH. pylori infection has been recognized as one of the most common infections in humans affecting almost half of the world population. Detection of Helicobacter pylori infection in resource limited areas mainly based on stool antigen test and serological test. Detection of H. pylori by using culture method has been a challenge especially in resource limited area because of the requirement need in growing and isolating this organism in laboratory. There is no study which has been done in Tanzania on detecting these bacteria by using culture method. METHODOLOGY: A cross-sectional study was conducted at Muhimbili National Hospital from September 2020 to February 2021. We consecutively enrolled patients undergoing upper endoscopy at Muhimbili National Hospital after meeting inclusion criteria. Detection of Helicobacter pylori infection was done using rapid urease test and those turned positive were taken for culture and sensitivity. Sensivity testing with the use of selected antibiotics was done using the disc diffusion method. The isolates with characteristics of gram-negative straight rods, oxidase-positive, urease-positive, and catalase-positive were identified as Helicobacter pylori.
resultsA total of 290 participants were involved in this study, 123 (42.4%) tested positive for H. pylori infection using rapid urease test. We were able to isolate H. pylori from 29 specimens by culture method from 123 (23.6%) specimens which were positive by rapid urease test. Helicobacter pylori resistance to clarithromycin, amoxicillin, metronidazole, levofloxacin, ciprofloxacin and tetracycline was 65.5%, 86.2%, 100%, 0%, 3.5%, and 31% respectively.
conclusionHelicobacter pylori infection is very common in resource limited areas. Detection of H. pylori using culture methods is very important, as it allows performance of antimicrobial susceptibility testing. Resistance to common antibiotics used in treating and eradicating H. pylori infection is very high. Extensive local studies using the recommended methods for antimicrobial susceptibly testing is advocated.
