Comparative genomic analysis of Mycoplasma related to cell culture for infB gene-based loop-mediated isothermal amplification.
Article in World journal of microbiology & biotechnology, 2023. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Mycoplasma contamination in cell culture affects the properties of cell lines. Gold standard detection by microbiological culture takes days and requires specialists. The polymerase chain reaction and loop-mediated isothermal amplification (LAMP) are fast molecular options, but LAMP only requires one heating block for DNA amplification. This study presents a comparative genomic analysis of Mycoplasma species to identify common target genes different from the rrsA gene, which encodes 16 S rRNA. The aim is to implement a LAMP assay to detect Mycoplasma species, reducing the time and specialized equipment required for detection. We performed a comparative genomic analysis through Mauve software and the GView server and selected infB and clpB genes as target candidates for designing LAMP primers. We evaluated both genes by multiple sequence alignment (MSA). The infB gene presented the best score MSA assessment with lower odd-log values (5,480,281) than other genes. We selected the infB gene to design LAMP primers specific to Mycoplasma spp. We used these primers to implement LAMP at 63 °C for 30 min, which showed 100% positive amplifications for detecting Mycoplasma spp. In conclusion, we present a methodology utilizing the infB gene-based LAMP assay to detect three of the six most prevalent Mycoplasma species in cell culture.
