A distinct lineage of giant viruses brings a rhodopsin photosystem to unicellular marine predators. [PDF]
, 2019 Giant viruses are remarkable for their large genomes, often rivaling those of small bacteria, and for having genes thought exclusive to cellular life.

Unexpected invasion of miniature inverted-repeat transposable elements in viral genomes
Mobile DNA, 2018 Background Transposable elements (TEs) are common and often present with high copy numbers in cellular genomes. Unlike in cellular organisms, TEs were previously thought to be either rare or absent in viruses.

The Role of Infection in Acute Exacerbation of Idiopathic Pulmonary Fibrosis
Mediators of Inflammation, Volume 2019, Issue 1, 2019., 2019 Background. Acute exacerbation of IPF (AE‐IPF) is associated with high mortality. We studied changes in pathogen involvement during AE‐IPF and explored a possible role of infection in AE‐IPF. Objectives. Our purpose is to investigate the role of infection in AE‐IPF. Methods. Overall, we recruited 170 IPF patients (48 AE‐IPF, 122 stable) and 70 controls

International Journal of Genomics, Volume 2018, Issue 1, 2018., 2018 The existence of complete genome sequences makes it important to develop different approaches for classification of large‐scale data sets and to make extraction of biological insights easier. Here, we propose an approach for classification of complete proteomes/protein sets based on protein distributions on some basic attributes.

Persistence of low pathogenic influenza A virus in water: a systematic review and quantitative meta-analysis [PDF]
, 2016 Avian influenza viruses are able to persist in the environment, in-between the transmission of the virus among its natural hosts. Quantifying the environmental factors that affect the persistence of avian influenza virus is important for influencing our ...

Microbial Ecology of Permafrost Soils: Populations, Processes, and Perspectives
Permafrost and Periglacial Processes, Volume 36, Issue 2, Page 245-258, April/June 2025.ABSTRACT Permafrost microbial research has flourished in the past decades, due in part to improvements in sampling and molecular techniques, but also the increased focus on the permafrost greenhouse gas feedback to climate change and other ecological processes in high latitude and alpine permafrost soils.

Importance of amoebae as a tool to isolate amoeba-resisting microorganisms and for their ecology and evolution: the Chlamydia paradigm. [PDF]
, 2014 Free-living amoebae are distributed worldwide and are frequently in contact with humans and animals. As cysts, they can survive in very harsh conditions and resist biocides and most disinfection procedures. Several microorganisms, called amoeba-resisting
