Cím:Heme Oxygenase-1 (HMX1) Loss of Function Increases the In-Host Fitness of the Saccharomyces 'boulardii' Probiotic Yeast in a Mouse Fungemia Model / Alexandra Imre, Renátó Kovács, Zoltán Tóth, László Majoros, Zsigmond Benkő, Walter P. Pfliegler, István Pócsi
Dátum:2022
ISSN:2309-608X
Megjegyzések:The use of yeast-containing probiotics is on the rise; however, these products occasionally cause fungal infections and possibly even fungemia among susceptible probiotic-treated patients. The incidence of such cases is probably underestimated, which is why it is important to delve deeper into the pathomechanism and the adaptive features of S. ♭boulardii'. Here in this study, the potential role of the gene heme oxygenase-1 (HMX1) in probiotic yeast bloodstream-derived infections was studied by generating marker-free HMX1 deletion mutants with CRISPR/Cas9 technology from both commercial and clinical S. ♭boulardii' isolates. The six commercial and clinical yeasts used here represented closely related but different genetic backgrounds as revealed by comparative genomic analysis. We compared the wild-type isolates against deletion mutants for their tolerance of iron starvation, hemolytic activity, as well as kidney burden in immunosuppressed BALB/c mice after lateral tail vein injection. Our results reveal that the lack of HMX1 in S. ♭boulardii' significantly (p < 0.0001) increases the kidney burden of the mice in most genetic backgrounds, while at the same time causes decreased growth in iron-deprived media in vitro. These findings indicate that even a single-gene loss-of-function mutation can, surprisingly, cause elevated fitness in the host during an opportunistic systemic infection. Our findings indicate that the safety assessment of S. ♭boulardii' strains should not only take strain-to-strain variation into account, but also avoid extrapolating in vitro results to in vivo virulence factor determination.

Cím:Virulence Factors and in-Host Selection on Phenotypes in Infectious Probiotic Yeast Isolates (Saccharomyces 'boulardii') / Alexandra Imre, Renátó Kovács, Kitti Pázmándi, Dániel Nemes, Ágnes Jakab, Tünde Fekete, Hanna Viktória Rácz, Ilona Dóczi, Ildikó Bácskay, Attila Gácser, Károly Kovács, László Majoros, Zoltán Farkas, István Pócsi, Walter P.

Megjegyzések:Saccharomyces yeast probiotics (S. 'boulardii') have long been applied in the treatment of several gastrointestinal conditions. Despite their widespread use, they are rare opportunistic path-ogens responsible for a high proportion of Saccharomyces mycosis cases. The potential virulence at-tributes of S. 'boulardii' as well as its interactions with the human immune system have been studied, however, no information is available on how these yeasts may change due to in-host evolution. To fill this gap, we compared the general phenotypic characteristics, cell morphology, virulence factors, epithelial and immunological interactions, and pathogenicity of four probiotic product samples, two mycosis, and eight non-mycosis samples of S. 'boulardii'. We assessed the characteristics related to major steps of yeast infections. Mycosis and non-mycosis isolates both displayed novel characters when compared to the product isolates, but in the case of most virulence factors and in pathogenic-ity, differences were negligible or, surprisingly, the yeasts from products showed elevated levels. No isolates inflicted considerable damage to the epithelial model or bore the hallmarks of immune evasion. Our results show that strains in probiotic products possess characteristics that enable them to act as pathogens upon permissive conditions, and their entry into the bloodstream is not due to active mechanisms but depends on the host. Survival in the host is dependent on yeast phenotypic characteristics which may change in many ways once they start evolving in the host. These facts call attention to the shortcomings of virulence phenotyping in yeast research, and the need for a more thorough assessment of probiotic use.

Cím:A new, rapid multiplex PCR method identifies frequent probiotic origin among clinical Saccharomyces isolates / Imre Alexandra, Rácz Hanna Viktória, Antunovics Zsuzsa, Rádai Zoltán, Kovács Renátó, Lopandic Ksenija, Pócsi István, Pfliegler Walter P.

Megjegyzések:An increasing number of infections originating from probiotic use are reported worldwide, with the majority of such cases caused by the yeast Saccharomyces 'boulardii', a subtype of S. cerevisiae. Reliably linking infectious cases to probiotic products requires unequivocal genotyping data, however, these techniques are often timeconsuming and difficult to implement in routine diagnostics. This leads to a widespread lack of genetic data regarding the origin of Saccharomyces infections. We propose a quick and reliable PCR-based protocol for the identification of S. 'boulardii' based on a combined analysis of interdelta fingerprinting and microsatellite typing. By applying various typing methods and our proposed method to the clinical yeast collection of a Hungarian hospital we show that probiotic origin is common among clinical Saccharomyces, and that the new multiplex method enables rapid and unequivocal identification of probiotic yeast infections. This method can be applied for the identification of yeast infection sources, helping decisions on probiotic use.

Cím:How to characterize a strain? Clonal heterogeneity in industrial influences both phenotypes and heterogeneity in phenotypes / Hanna Viktória Rácz, Fezan Mukhtar, Alexandra Imre, Zoltán Rádai, Andreas Károly Gombert, Tamás Rátonyi, János Nagy, István Pócsi, Walter P. Pfliegler

Megjegyzések:Populations of microbes are constantly evolving heterogeneity that selection acts upon, yet heterogeneity is non?trivial to assess methodologically. The necessary practice of isolating single cell colonies and thus, subclone lineages for establishing, transferring, and using a strain results in single?cell bottlenecks with a generally neglected effect on the characteristics of the strain itself. Here, we present evidence that various subclone lineages for industrial yeasts sequenced for recent genomic studies show considerable differences, ranging from loss?of?heterozygosity to aneuploidies. Subsequently, we assessed whether phenotypic heterogeneity is also observable in industrial yeast, by individually testing subclone lineages obtained from products. Phenotyping of industrial yeast samples and their newly isolated subclones showed that single?cell bottlenecks during isolation can indeed considerably influence the observable phenotype. Next, we decoupled fitness distributions on the level of individual cells from clonal interference by plating single cell colonies and quantifying colony area distributions. We describe and apply an approach using statistical modeling to compare the heterogeneity in phenotypes accross samples and subclone lineages. One strain was further used to show how individual subclonal lineages are remarkably different not just in phenotype, but also in the level of heterogeneity in phenotype. With these observations, we call attention to the fact that choosing an initial clonal lineage from an industrial yeast strain may vastly influence downstream performances and observations on karyotype, phenotype, and also on heterogeneity.
