Achilles, a new family of transcriptionally active retrotransposons from the olive fruit fly, with y chromosome preferential distribution
(2015)Sex chromosomes have many unusual features relative to autosomes. The in depth exploration of their structure will improve our understanding of their origin and divergence (degeneration) as well as the evolution of genetic ... -
Acute non-A, non-B, non-C hepatitis differences and similarities between hepatitis E virus infection and autoimmune hepatitis, with phylogenetic analysis of hepatitis E virus in humans and wild boars
(2022)Background Hepatitis E virus (HEV) infection incidence is increasing in Europe, accounting for the majority of acute hepatitis cases. We investigated the prevalence and clinical characteristics of acute hepatitis E (AHE) ... -
Ancestral Absence of Electron Transport Chains in Patescibacteria and DPANN
(2020)Recent discoveries suggest that the candidate superphyla Patescibacteria and DPANN constitute a large fraction of the phylogenetic diversity of Bacteria and Archaea. Their small genomes and limited coding potential have ... -
Antimicrobial resistance, flaa sequencing, and phylogenetic analysis of campylobacter isolates from broiler chicken flocks in greece
(2021)Human campylobacteriosis caused by thermophilic Campylobacter species is the most commonly reported foodborne zoonosis. Consumption of contaminated poultry meat is regarded as the main source of human infection. This study ... -
Bacterial and archaeal phylotypes associated with distinct mineralogical layers of a white smoker spire from a deep-sea hydrothermal vent site (9°N, East Pacific Rise)
(2006)A diffusely venting chimney spire from the East Pacific Rise (9°N) was analysed by petrographic thin sectioning and 16S rRNA gene cloning and sequencing in parallel, to correlate microbial community composition with ... -
Biochemical and genetic evidence for the presence of multiple phosphatidylinositol- and phosphatidylinositol 4,5-bisphosphate-specific phospholipases C in Tetrahymena
(2011)Eukaryotic phosphoinositide-specific phospholipases C (PI-PLC) specifically hydrolyze phosphatidylinositol 4,5-bisphosphate [PtdIns(4,5)P2], produce the Ca2+-mobilizing agent inositol 1,4,5-trisphosphate, and regulate ... -
Cerebral and non-cerebral coenurosis: on the genotypic and phenotypic diversity of Taenia multiceps
(2016)We characterised the causative agents of cerebral and non-cerebral coenurosis in livestock by determining the mitochondrial genotypes and morphological phenotypes of 52 Taenia multiceps isolates from a wide geographical ... -
Characterization and Quantitative Determination of a Diverse Group of Bacillus subtilis subsp. subtilis NCIB 3610 Antibacterial Peptides
(2021)Five antibacterial peptides produced by Bacillus subtilis NCIB 3610 were purified, quantified, characterized, and identified in the present study. Cell-free extracts were subjected to three purification protocols employing ... -
Collagen from the marine sponges Axinella cannabina and Suberites carnosus: Isolation and morphological, biochemical, and biophysical characterization
(2017)In search of alternative and safer sources of collagen for biomedical applications, the marine demosponges Axinella cannabina and Suberites carnosus, collected from the Aegean and the Ionian Seas, respectively, were ... -
Comparative Analysis of SARS-CoV-2 Variants of Concern, Including Omicron, Highlights Their Common and Distinctive Amino Acid Substitution Patterns, Especially at the Spike ORF
(2022)In order to gain a deeper understanding of the recently emerged and highly divergent Omicron variant of concern (VoC), a study of amino acid substitution (AAS) patterns was performed and compared with those of the other ... -
The complex evolutionary history of aminoacyl-tRNA synthetases
(2017)Aminoacyl-tRNA synthetases (AARSs) are a superfamily of enzymes responsible for the faithful translation of the genetic code and have lately become a prominent target for synthetic biologists. Our largescale analysis of > ... -
Cryptosporidium in fish: Implications for aquaculture and beyond
(2021)Aquaculture industries are expanding worldwide and control of Cryptosporidium is of great importance. Cryptosporidiosis is a serious waterborne/foodborne disease, responsible for infectious outbreaks globally. Current ... -
Detection and molecular characterization of a new genotype of infectious bursal disease virus in Portugal
(2022)Infectious bursal disease virus (IBDV) is an immunosuppressive pathogen with a bi-segmented, double-stranded RNA genome. Two serotypes, named 1 and 2, are recognized, and serotype 1 is traditionally divided into classical, ... -
The effect of biochar feedstock, pyrolysis temperature, and application rate on the reduction of ammonia volatilisation from biochar-amended soil
(2018)Ammonia (NH3) volatilisation is one of the most important causes of nitrogen (N) loss in soil-plant systems worldwide. Carbon-based amendments such as biochar have been shown to mitigate NH3 volatilisation in agricultural ... -
ESBL-Producing Moellerella wisconsensis—The Contribution of Wild Birds in the Dissemination of a Zoonotic Pathogen
(2022)Moellerella wisconsensis is an Enterobacteriaceae with unclarified dispersion and pathogenic-ity. During an ongoing investigation about antimicrobial resistance in Greece, the occurrence of M. wisconsensis was evaluated ... -
First description in Greece of mphC-positive staphylococci causing subclinical mastitis in Ewes
(2018)The aim of the present study was to describe the first mphC-positive staphylococci, including two Staphylococcus lentus (Sle-087lar and Sle-091lar) and one Staphylococcus xylosus (Sxy-228lar), isolated from samples of ... -
First evidence of Leishmania infection in European brown hare (Lepus europaeus) in Greece: GIS analysis and phylogenetic position within the Leishmania spp
(2016)Although the existence of a sylvatic transmission cycle of Leishmania spp., independent from the domestic cycle, has been proposed, data are scarce on Leishmania infection in wild mammals in Greece. In this study, we aimed ... -
First Identification and Molecular Characterization of Avian metapneumovirus Subtype B from Chickens in Greece
