“…Toxicity was determined on HL-60, HUVEC, and MCF10A cells, and in the alternative in vivo model Galleria mellonella. Analysis of sterol patterns after incubation gave valuable insights into the putative molecular mechanism of action, indicating inhibition of the enzymes sterol C14-reductase and sterol C8-isomerase in fungal ergosterol biosynthesis.…”

“…One paired set exhibited a higher proportion of clumping cells and was more virulent in the invertebrate host Galleria mellonella than the other paired set. No virulence difference between the paired index and FKS strains was observed. …”

“…Fenbendazole, MMV1782387, ravuconazole and olorofim were able to significantly prolong Galleria mellonella larvae survival and are promising candidates to explore in mycetoma treatment and to also serve as scaffolds for medicinal chemistry optimisation in the search for novel antifungals to treat eumycetoma.…”

“…Although hypermucoviscous, this strain possessed attenuated virulence according to serum killing assay and Galleria mellonella infection model. Notably, two copies of bla(NDM-1) were contained on two tandem ISCR1 elements and coexisted with bla(IMP-4) in a novel hybrid multidrug resistance plasmid. …”

“…Directed gene-knockout of BbSirT2 dramatically reduced conidiation, the ability of the fungus to metabolize a range of carbon and nitrogen sources, and tolerances to oxidative, heat, and UV stress and significantly attenuated virulence in both intrahemocoel injection and topical bioassays using the Greater wax moth (Galleria mellonella) as the insect host. ΔBbSirT2 cells showed alterations in cell cycle development and hyphal septation and produced morphologically aberrant conidia. …”

“…Among all the recovered nematode isolates, two of them, Oscheius tipulae TC2 and OC2, were evaluated for their capacity to control C. capitata flies and for their ability to kill and reproduce on Galleria mellonella larvae. Our results show a great potential of these two isolates as biocontrol agents as they kill C. capitata eggs and pupae and interfere with the metamorphosis of C. capitata larvae. …”

“…Despite limited effects on asexual cycles in vitro, knockout mutants of cfp1, cfp2 and cfp3 were severely compromised in their capability for normal cuticle infection, in which most tested Galleria mellonella larvae survived. The blocked cuticle infection concurred with reduced secretion of extracellular enzymes, including Pr1 proteases required cuticle penetration. …”

“…Mutagenesis of the essential swc4 gene in MbKisolate resulted in reduction of secondary-metabolite (SM) secretion and impaired virulence in Galleria mellonella. Our results suggest the role of SWC4 in the regulation of SMs and the role of both SWC4 and SWR1-C in virulence of M. brunneum isolates. …”

These findings suggest that Erg6 is a downstream effector of the transcription factor Flo8 that mediates the cross talk between sterol synthesis and virulence factors in C. albicans. …”

Comparative phylogenomic analysis of PINH-4250 and PINH-4900 along to an international collection of publicly available genomes of K. pneumoniae ST11 revealed that both environmental strains were closely related to hospital-associated K. pneumoniae strains recovered from clinical samples between 2006 and 2018, in São Paulo city. …”
