| Abstract |
The gastric microbiota has recently been implicated in the causation of organic/structural gastroduodenal diseases (gastric and duodenal ulcers, gastric cancer) in patients with Helicobacter pylori (H. pylori) infection. We aimed to ascertain, in patients harbouring H. pylori, the role of the gastric microbiota in the causation of symptoms (chronic dyspepsia) in the absence of organic disease. Seventy-four gastric biopsy samples obtained at endoscopy from patients with (n = 21) or without (n = 53) chronic dyspepsia, and that tested positive by the bedside rapid urease test for H. pylori infection, were cultured for detection of H. pylori and non-H. pylori organisms. The cultured organisms were identified by matrix-assisted laser desorption ionization time-of-flight mass spectroscopy (MALDI-TOF MS). A total of 106 non-H. pylori isolates were obtained from 74 patients' samples. This included 33 isolates (median 2, range 1-2 per patient) from dyspeptic and 73 (median 2, range 1-2 per patient) from non-dyspeptic patients. These were identified from the Bruker Biotyper 2 database as Staphylococcus spp., Streptococcus spp., Lactobacillus spp., Micrococcus spp., Enterococcus spp., Pseudomonas spp., Escherichia spp., Klebsiella spp. and Bacillus spp., Staphylococcus and Lactobacillus were identified significantly more commonly in dyspeptics and Streptococcus, Pseudomonas, Escherichia coli and Klebsiella pneumoniae in non-dyspeptics. All identified organisms belonged to the phyla Firmicutes and Proteobacteria. There is a qualitative difference in the gastric microbial spectrum between patients harbouring H. pylori with and without chronic dyspepsia. Whether these organisms have an independent role in the development or prevention of dyspepsia or act in concurrence with H. pylori needs study. |

Attention Score in Context
This research output has an Altmetric Attention Score of 12. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 05 February 2018.
All research outputs
#2,864,010
of 24,093,053 outputs
Outputs from BMC Gastroenterology
#162
of 1,868 outputs
Outputs of similar age
#65,439
of 447,786 outputs
Outputs of similar age from BMC Gastroenterology
#5
of 31 outputs
Altmetric has tracked 24,093,053 research outputs across all sources so far. Compared to these this one has done well and is in the 88th percentile: it's in the top 25% of all research outputs ever tracked by Altmetric.
So far Altmetric has tracked 1,868 research outputs from this source. They typically receive a little more attention than average, with a mean Attention Score of 6.5. This one has done particularly well, scoring higher than 91% of its peers.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 447,786 tracked outputs that were published within six weeks on either side of this one in any source. This one has done well, scoring higher than 85% of its contemporaries.
We're also able to compare this research output to 31 others from the same source and published within six weeks on either side of this one. This one has done well, scoring higher than 87% of its contemporaries.
