Bacteriophages were observed in forestomach contents from three species of Australian macropodoid marsupials possessing a foregut fermentative digestion: the eastern grey kangaroo (Macropus giganteus), the eastern wallaroo (Macropus robustus robustus), and the rufous bettong (Aepyprymnus rufescens). Forty-six morphologically distinct phage types, representing the families Myoviridae, Siphovirid...

Vibrio parahaemolyticus is a major pathogen that is mainly associated with seafood and is a global food safety issue. Our objective was to isolate and completely sequence a specific phage against this bacterium. Phage vB_VpaM_MAR is able to lyse 76% of the V. parahaemolyticus strains tested. MAR belongs to the Myoviridae family and has a genome comprised of double-stranded DNA with a size of 41...

PCR-based detection of Myoviridae lysogenic phages in Burkholderia pseudomallei was developed using primers targeting K96243 prophage GI2, phiE12-2 and phi52237/phiX216. Investigation of 50 clinical and 50 environmental (soil) isolates revealed that K96243 prophage GI2 was the most common (48%) among the isolates, followed by phiE12-2 (38%) and phi52237/phiX216 (35%), with K96243 prophage GI2 b...

Bacteriophages, as the most abundant biological entities on Earth, place significant predation pressure on their hosts. This pressure plays a critical role in the evolution, diversity, and abundance of bacteria. In addition, phages modulate the genetic diversity of prokaryotic communities through the transfer of auxiliary metabolic genes. Various studies have been conducted in diverse ecosystem...

The aquatic microbiome is composed of a multi-phylotype community of microbes, ranging from the numerically dominant viruses to the phylogenetically diverse unicellular phytoplankton. They influence key biogeochemical processes and form the base of marine food webs, becoming food for secondary consumers. Due to recent advances in next-generation sequencing, this previously overlooked component ...

Cyanobacteria and their phages are significant microbial components of the freshwater and marine environments. We identified a lytic phage, Ma-LMM01, infecting Microcystis aeruginosa, a cyanobacterium that forms toxic blooms on the surfaces of freshwater lakes. Here, we describe the first sequenced freshwater cyanomyovirus genome of Ma-LMM01. The linear, circularly permuted, and terminally redu...
