Abstract.Wolbachia are obligatory intracellular and maternally inherited bacteria, known to infect many species of arthropod. In this study, we discovered a bacteriophage-like genetic element in Wolbachia, which was tentatively named bacteriophage WO. The phylogenetic tree based on phage WO genes of several Wolbachia strains was not congruent with that based on chromosomal genes of the same strains, suggesting that phage WO was active and horizontally transmitted among various Wolbachia strains… Expand
A Survey of the bacteriophage WO in the endosymbiotic bacteria Wolbachia.
TLDR
Phage infection was checked in 31 Wolbachia strains, which induce 5 different effects in their hosts and infect 25 insect species and 3 nematodes, and phylogenetic analyses show a lack of congruency between WolbachIA or insect and phage WO phylogenies, indicating numerous horizontal transfers of phage among the different Wolbachian strains.

Survey of Wolbachia and Its Phage WO in the Uzifly Exorista sorbillans (Diptera: Tachinidae)
TLDR
The survey of Wolbachia and WO phage infections in 20 populations of the Uzifly Exorista sorbillans, a tachinid endoparasite of silkworm Bombyx mori, collected from different geographic regions of India revealed 100% of double infections by the arthropod supergroups A and B. Expand
Detection of phage and in-silico analysis of WO phage associated cif genes from Wolbachia: A study based on Drosophila model
TLDR
Functional validation of the key findings in the study can help in establishing Wolbachia as a robust model for vector borne disease control. Expand
Diversity, distribution and specificity of WO phage infection in Wolbachia of four insect species
TLDR
Five different phages are identified in six Wolbachia strains, some are specific for a given bacterial strain whereas others are not, but globally phage infection appears stable on a large geographical scale and across insect generations. Expand
Distribution and Evolution of the Bacteriophage WO and Its Antagonism With Wolbachia
TLDR
This study is the first to report that in infected fig wasps, the genomes of all the Wolbachia strains had only one cryptic WO prophage, which contained defects in the genomic structural modules, contrary to the widely accepted understanding. Expand
Phage WO of Wolbachia: lambda of the endosymbiont world.
TLDR
How studies on the temperate bacteriophage WO of Wolbachia have revealed unexpected levels of genomic flux and are challenging previously held views about the clonality of obligate intracellular bacteria is discussed. Expand
WO bacteriophage transcription in Wolbachia-infected Culex pipiens.
TLDR
WO phage associated with multiple Wolbachia-infected Culex strains and an uninfected strain are characterized using electron microscopy and RT-PCR, providing evidence for the presence of both actively transcribed virions and inactive prophages. Expand
Molecular detection of Wolbachia and phage WO infection in Spodoptera litura. (Lepidoptera: Noctuidae)
TLDR
This result creates possible implications of cytoplasmic bacteria Wolbachia and phage WO infection for the management Spodoptera litura a serious menace of agricultural crops. Expand
Isolation and characterization of the bacteriophage WO from Wolbachia, an arthropod endosymbiont.
TLDR
Bacteriophage particles isolated from Wolbachia for the first time had an isometric head that was approximately 40 nm in diameter and contained linear double-stranded DNA of approximately 20 kbp, and there were 24 open reading frames including a structural gene module, and genes for replication and lysogenic conversion.

The Wolbachia WO bacteriophage proteome in the Aedes albopictus C/wStr1 cell line: evidence for lytic activity?
TLDR
Understanding of wStr in a host cell line derived from the mosquito, Aedes albopictus, is expanded and provided a basis for investigating conditions that favor the lytic phase of the WO phage life cycle and recovery of infectious phage particles. Expand

Wolbachia endosymbionts responsible for various alterations of sexuality in arthropods
TLDR
Three molecular lineages can be identified on the basis of 16S as well as 23S sequences, and Wolbachia spread by horizontal transfer across host lineages as evidenced by their diversification which occurred long after that of their hosts, and by the non-congruence of the phylogenetic relationships of symbionts and their hosts.

It was shown that Wolbachia in E. cautella cause complete cy toplasmic incompatibility: no egg-hatch was observed in the cross between infected males and uninfected females, and both Tsuchiura and Yokohama strains of E. kuehniella showed partial cytoplasmi incompatibility, but the levels were significantly different between the two strains.
