- We describe a rare case of a 35-year-old female patient suffering from polymicrobial hematogenous vertebral osteomyelitis caused by vaginal microbiota following sexual intercourse. Anaerobic blood cultures yielded Fannyhessea vaginae and Gemelliphila asaccharolytica, and intraoperative tissue cultures from decompression surgery identified Gardnerella vaginalis. Beyond Fannyhessea vaginae and Gemelliphila asaccharolytica, 16S rRNA gene Nanopore sequencing of surgical tissue also detected high amounts of Parvimonas parva, Peptostreptococcus anaerobius, Marseillibacter massiliensis, and Gemelliphila palaticanis. Antibiotic treatment with broad anaerobic coverage resulted in complete clinical resolution. Retrospective metagenomic analysis of a cervical swab obtained 9 months earlier revealed Fannyhessea vaginae and G. vaginalis to be already present in the vaginal microbiota. This case highlights the potential for hematogenous dissemination of vaginal anaerobes after sexual intercourse and underscores the diagnostic challenges posed by fastidious anaerobic bacteria. Molecular techniques are helpful tools in uncovering pathogens that may escape conventional culture methods. - Source: PubMed

Vock IsabelleBargetzi AnnikaWeisser MajaMueller Olivia KatharinaJunker MilenaMehrkens ArneNeidhoefer ClaudioHamelin BaptisteHosch SalomeMertz Kirsten DKeller Peter MKuehl Richard - The mitochondrial ATP synthase catalyzes the formation of ATP from ADP and Pi. In the colorless alga Polytomella parva, this enzyme displays an atypical composition in the subunits that build the peripheral arm and in the ones involved in its dimerization. In addition to ten extra subunits (Asa1-10) apparently absent from other ATP synthases, the catalytic α and β subunits possess amino-acid extensions in their N- and C-terminal regions, respectively. The δ subunit-homologous to the bacterial ε subunit and responsible for linking the hydrophilic and hydrophobic sectors of the enzyme-also contains an atypical N-terminal extension. The ATP synthase of P. parva appears to lack an IF peptide, the natural inhibitor of ATP hydrolysis. Due to the potential closeness of the δ subunit N-terminal extension to the DELSEED region of the catalytical core of the enzyme, we hypothesized that the δ subunit could regulate the hydrolytic activity of the algal ATP synthase and evaluated this possibility experimentally. We also investigated whether the S. cerevisiae IF polypeptide could exert a cross-species inhibitory effect on the algal enzyme. Biochemical results, complexome profiling analysis, and 3D-structural data indicate the absence of a peptide with inhibitory capabilities in the algal ATP synthase and suggest that the enzyme hydrolytic activity may be regulated by ADP levels. - Source: PubMed

Ostolga-Chavarría MarcosVázquez-Acevedo MiriamGiraud Marie-FranceCabrera-Orefice AlfredoHalphen Diego González - Species of are soil-borne fungi that are distributed in temperate, sub-tropical and tropical regions of the world. Very little is known regarding the biology of these fungi that are mostly considered as saprobes, but there have also been reports of pathogenicity in some cases. Prior to this study, 46 species of were known based on DNA sequence comparisons and phylogenetic analyses. Only seven of those species have been reported from China, some of which were associated with diseases of woody plants. In this study, soil samples were collected from natural forests and plantations in eight provinces (autonomous regions) of northeastern, central, southeastern, southwestern, and southern regions of China. A total of 914 soil samples were analysed, resulting in 407 isolates. They were identified based on morphological characteristics and phylogenetic analyses of DNA sequence data for the , , , and ITS regions. This resulted in the identification of eight known, and 22 novel species. spp. tended to be widely distributed in forest soils across a wide range of climatic zones. The species diversity in warm areas was higher than in cooler areas. Of the 68 species now recognised and verified based on DNA data, these fungi are known from more than 25 countries, of which 57 species were isolated from soils, 18 from plant tissues, and nine from both soils and plant tissues. Species with wide geographic distributions including putative pathogens such as, and that have been found on multiple plant species, while others are confined to more limited niches. The exceptionally large number of new species found in this study suggests that species have been poorly sampled and that many more are likely to be found in warm and humid environments. Overall, this study provides a foundation for future investigations aimed at clarifying the evolutionary relationships, ecology, and pathology of this interesting and little understood genus.

Zhou W WDong H BZhou H XCrous P WWingfield M JChen S F - Pheidole parva Mayr (1865) is a small ubiquitous ant native to the Indomalayan region where it is considered a pest in healthcare facilities. This tramp ant was first reported outside its native range more than 100 years ago in the Seychelles Islands. Since then, it has been found in other areas of the Old World, where it was likely accidentally introduced via trading ships. In the 2000s, this ant was detected in Japan (2001), the Arabian Peninsula (2009), and recently in the Mediterranean island of Cyprus (2023) and Lebanon (2025). Here, we describe its first occurrence in North America, in the state of Florida where both Nearctic and Neotropical realms meet. Our findings are based on recent Pheidole parva specimens collected throughout the state, curated iNaturalist observations, Antweb data, and DNA barcoding based on the mitochondrial cytochrome oxidase subunit I (COI) gene. Among the 26 P. parva specimens analyzed from Florida, we found three different COI haplotypes. Two of them were also found in other introduced areas; however, one of the haplotypes has only been detected in a native population. The three haplotypes were distributed throughout the state with no clear geographical structure, consistent with multiple introductions and broad establishment of this non-native ant in Florida. - Source: PubMed

The marsh pitcher plant (Heliamphora sp.) is a genus of carnivorous plant in which the production of endogenous enzymes for prey digestion is still dubious. In this study, we tried to elucidate the ability of prey digestion by the plant's own hydrolytic enzymes in H. parva, H. neblinae, and the hybrid H. heterodoxa × minor. Three Heliamphora taxa were fed on fruit flies, and pitcher fluids were analyzed using liquid chromatography-electrospray ionization-tandem mass spectrometry (LC-ESI-MS/MS), Western blots, and enzyme activity measurements for the presence of endogenous hydrolytic enzymes. Production of the enzymes in pitchers through ontogeny was also investigated. Asian pitcher plant Nepenthes truncata was used as a reference carnivorous plant. All investigated taxa produced plant-derived hydrolytic enzymes similar to those found in other carnivorous plant genera. The most important are aspartic protease, subtilisin-like protease, type III chitinase, β-1,3-glucanase, purple acid phosphatase, and GDSL esterase/lipase. Although some variability exists among studied taxa, in general, the activity of phosphatase and proteolytic enzymes was low and increased over time, irrespective of feeding status. Immunoblotting of aspartic protease showed that the abundance of the enzyme in pitcher fluid can accumulate developmentally without any prey stimuli. The microbial and prey-derived proteins were almost exclusively detected in fed samples. In conclusion, our study suggests that the species of the genus Heliamphora can be considered as holocarnivorous plants with the ability to produce their own endogenous hydrolytic enzymes, which, however, does not rule out the contribution of microbial digestion in their natural habitat. Moreover, their own digestive potential can be strongly diminished in nature due to the absence of a protective lid and high rainfall in some parts of the year, diluting the pitcher fluids. - Source: PubMed
