Safety aspects and in vitro probiotic assessment of Kluyveromyces marxianus strains from neonatal faeces.
Article in Antonie van Leeuwenhoek, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 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
The isolation and identification of probiotic yeasts is increasing rapidly. In this context, the present study aimed to isolate and identify yeast strains from neonatal faeces in Erzurum province, Türkiye and to determine their probiotic characteristics. A total of 12 yeast strains were isolated and genotypic characterization revealed the presence of seven different species, including Kluyveromyces marxianus, Candida spp. Clavispora lusitaniae, Geotrichum candidum, Trichophyton rubrum, Pichia cactophila, and Meyerozyma guilliermondii. The non-pathogenic and potentially probiotic characteristics of the K. marxianus M2, M9, and M10 strains were further investigated. Although yeast has been isolated from neonatal faeces before, K. marxianus was isolated for the first time in this study. The results revealed that the K. marxianus strains exhibited high resistance to simulated gastric juice and bile salts. The auto-aggregation percentages of the strains ranged from 92.55 to 94.78% after 4 h, while the co-aggregation percentages with pathogens ranged from 19.70 to 53.09%. The K. marxianus M2 strain exhibited the highest degree of hydrophobicity (74.97%), and none of the strains demonstrated DN-ase or haemolytic activity. Furthermore, M2 and M9 strains displayed bile salt hydrolase activity. In conclusion, based on in vitro probiotic test results, K. marxianus strains were selected as probiotic yeast candidates for further studies, especially in patients under antibiotic therapy.
