Pseudomonas aeruginosa elongation factor-Tu (EF-Tu) is an immunogenic protective protein antigen.
Article in Vaccine, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 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
Pseudomonas aeruginosa is a Gram-negative, opportunistic pathogen that infects immunocompromised individuals, especially in the hospital setting. This bacterium is an important pathogen in people with weakened immune systems, injuries, and other underlying physiologic dysfunctions. P. aeruginosa is responsible for up to 20 % of all hospital-acquired pneumonias. It is one of the major causes of nosocomial infections and has been noted to be one of the most common bacteria co-infecting patients with COVID-19 or causing super-infections following COVID-19 infections. Despite improvements in antimicrobial therapy and hospital care, P. aeruginosa bacteremia and pneumonia remain fatal in about 30 % of cases. P. aeruginosa is also the leading cause of chronic life-threatening lung infections in cystic fibrosis patients. This bacterium is naturally antibiotic resistant, and infections are notoriously difficult to treat once established, with no vaccine available. We have previously shown that elongation factor-Tu (EF-Tu), a protein best known for its role in protein synthesis, is surface exposed on P. aeruginosa. As this protein is highly expressed, evolutionally conserved, and essential, we hypothesized it would make a good vaccine target. In this study, we found that P. aeruginosa EF-Tu is immunogenic in people, and that mice can develop an immune response following immunization with recombinant P. aeruginosa EF-Tu. Furthermore, immunized mice were protected from subsequent P. aeruginosa pneumonia and transfer of this vaccine antisera to naïve mice resulted in decreased colonization. Altogether these findings support the consideration of EF-Tu as a new vaccine candidate against P. aeruginosa.
