Prevalence of virulence genes in strains of Campylobacter jejuni isolated from human, bovine and broiler.
Article in Brazilian journal of microbiology : [publication of the Brazilian Society for Microbiology], 2013. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 17 papers.
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
Campylobacter jejuni isolates of different origins (bovine, broiler meat, human) were screened by polymerase chain reaction for the presence of 4 genes cdtB, cst-II, ggt, and virB11, previously linked to virulence such as adherence, invasion, colonization, molecular mimicry, and cytotoxin production. In addition, the isolates were screened for the presence of the global gene regulator csrA linked to oxidative stress responses, biofilms formation, and cell adhesion. All the C. jejuni isolates were positive for cdtB gene. The csrA gene was detected in 100% and 92% of C. jejuni isolates from human and animal origin and the virB11 gene was detected in 7.3% and 3.6% isolates from chicken and human respectively. All isolates from bovine were negative for the virB11 gene. The isolates showed a wide variation for the presence of the remaining genes. Of the C. jejuni recovered from human 83.6%, and 32.7% were positive for cst-II, and ggt respectively. Out of the isolates from chicken 40% and 5.5% isolates revealed the presence of cst-II, and ggt, respectively. Finally of the C. jejuni isolates from bovine, 97.7% and 22.7% were positive for cst-II, and ggt respectively. We conclude that the genes of this study circulate among humans and animals. These results led us to hypothesize that the isolates associated with enteritis (cdtB positives) are not selected by environmental or host-specific factors. On the other hand, the high frequencies of csrA gene in C. jejuni show that this gene is important for the survival of C. jejuni in animals and humans.
