Peritonitis caused by dematiaceous molds is uncommon but poses a significant threat to patients undergoing peritoneal dialysis (PD), leading high mortality and morbidity. This report highlights three cases of peritonitis distinct species Diaporthe (D. amygdali, D. eucalyptorum, phaseolorum), initially unidentified through conventional culture methods. The nucleotide sequences internal transcribed spacer regions (ITS), 18S nuclear ribosomal small subunit (SSU), 28S large (LSU) the DNA gene correctly identified isolates. Despite early catheter removal administration appropriate antifungal medications, all experienced fatal outcomes. barcoding emerges as valuable tool for accurately diagnosing within genus pathogenic microbes, aiding in identifying root causes infections. It emphasizes importance strict adherence aseptic techniques during PD exchanges prevent plant-borne pathogens.

Abstract Diaporthe is an important plant pathogenic genus, which also occurs as endophytes and saprobes. Many species that are morphologically similar proved to be genetically distinct. The current understanding of taxonomy by applying morphological characters, host associations multi-gene phylogeny problematic leading overestimation/underestimation numbers this significant fungal genus. Currently, there no definite boundaries for the accepted species. Hence, present study aims re-structure genus , based on single gene phylogenies (ITS, tef tub cal his ), justified GCPSR (Genealogical Concordance Phylogenetic Species Recognition) methodology well coalescence-based models (PTP—Poisson Tree Processes mPTP—multi-rate Poisson Processes). Considering all available type isolates divided into seven sections while 13 15 species-complexes proposed. To support re-assessment 82 obtained from woody hosts in Guizhou Province China were investigated revealed presence two novel 17 previously known Synonymies specified 31 molecular data studies. Dividing several specific phylogenetic analyses can avoid construction lengthy trees entire future taxonomic In other words, when one conducts research related only appropriate section need selected analysis.

Considering that fungi display a great morphological, ecological, metabolic, and phylogenetic diversity, their taxonomic identification is extremely important because it helps us establish information about each species its possible biochemical ecological roles. Traditionally, the of at level has been carried out with molecular tools such as DNA sequencing, but still represents huge challenge today due to heterogeneity fungal kingdom, making task complex difficult process. Biotyping, type chemotaxonomy, developed in field identification/differentiation classification micro-fungi through mass spectrometry (MS). Here, two endophytic strains isolated from different hosts were cultivated studied regarding morphology biology. Morphology analysis determined Diaporthe, results grouped them D. melongenae. We sought faster less way differentiating these interest an MS chemical profile MS/MS data using low-resolution spectrometer. Additionally, we linked this structure compounds previously genus Diaporthe. Studies conducted technique allowed propose distinctive molecules are unique strain share common (13 total). In addition, first report secondary metabolites The dataset demonstrates under investigation can be distinguished via spectrometry, suggesting host affinity; both exhibits pronounced differences profiles across all culture media incubation periods parameters described herein.

In this study, the complete mitogenomes of three Diaporthe species (Diaportheeres ZM79-3, D.phaseolorum ZM33-4 and sp. ZM41-5) were sequenced, assembled compared with other previously sequenced (D.caulivora VNIIKR SE Dcaul3, D.longicolla MSPL 10-6 D.sojae Dps12). The six found to be circular DNA molecules, lengths ranging from 53,646 bp 108,865 bp. mainly comprised same set 15 core protein-coding genes (PCGs), two rRNAs, a certain number tRNAs unidentified open reading frames (ORFs). PCG length, AT skew GC showed large variability among PCGs in mitogenomes. nad1 gene had least K2P genetic distance 13 Diaporthales species, indicating that was highly conserved. Ka/Ks values for all < 1, suggesting these subject purifying selection. Comparative mitogenome analysis introns contributed most size variation Frequent intron loss/gain events detected have occurred cox1 during evolution Although undergone large-scale rearrangements, identical arrangements. Phylogenetic based on combined mitochondrial datasets formed well-supported topologies. To our knowledge, study is first report ZM41-5, as well comparison species.

Phytopathogenic fungi induce severe diseases in plant hosts, potentially leading to significant crop quantity and quality reductions. In this study, we isolated identified pathogenic that threaten the successful cultivation of annual perennial crops northern Thailand. Samples with leaf spots, fruit rot, wilting, dieback symptoms were collected from 19 different Chiang Rai, Mai, Sakon Nakhon provinces Out 183 isolates, 27 selected for molecular analysis multi-gene phylogenetic study based on their diverse host range, geographical distribution, an initial morphological assessment. Four most species-diverse fungal genera - Colletotrichum, Diaporthe, Fusarium, Neopestalotiopsis identified, along 23 taxa, including four novel species.
