Streptomyces phages WheeHeim and Forthebois are two novel members of the Tectiviridae family. These phages were isolated on cultures of the plant pathogen Streptomyces scabiei, known for its worldwide economic impact on potato crops. Transmission electron microscopy showed viral particles with double-layered icosahedral capsids, and frequent instances of protruding nanotubes harboring a collar-like structure. Mass-spectrometry confirmed the presence of lipids in the virion, and serial purification of colonies from turbid plaques and immunity testing revealed that both phages are temperate. Streptomyces phages WheeHeim and Forthebois have linear dsDNA chromosomes (18,266 bp and 18,251 bp long, respectively) with the characteristic two-segment architecture of the Tectiviridae. Both genomes encode homologs of the canonical tectiviral proteins (major capsid protein, packaging ATPase and DNA polymerase), as well as PRD1-type virion-associated transglycosylase and membrane DNA delivery proteins. Comparative genomics and phylogenetic analyses firmly establish that these two phages, together with Rhodococcus phage Toil, form a new genus within the Tectiviridae, which we have tentatively named Deltatectivirus. The identification of a cohesive clade of Actinobacteria-infecting tectiviruses with conserved genome structure but with scant sequence similarity to members of other tectiviral genera confirms that the Tectiviridae are an ancient lineage infecting a broad range of bacterial hosts.

Although health researchers have begun to examine the forms of violence and power dynamics that play out in the intimate relationships of female sex workers (FSWs) in India, this knowledge has tended to focus on the perspectives of women, leaving men's motivations and attitudes relatively unexamined. This paper examines the contours of masculinity and gender norms from the perspective of the intimate partners of FSWs. Based on six months of ethnographic research in Northern Karnataka, the study employed two focus group discussions (FGDs) with Devadasi FSWs (N = 17), as well as four FGDs (N = 34) and 30 in-depth interviews with their intimate partners. Given the precarious labour conditions in this region, tensions developed in the participants' relationships with FSWs, as these men were unable to meet local ideals of manhood. Violence became a way that men attempted to re-secure a sense of control in their relationships with women, and to fulfil fantasies of male power. We recommend that programs engaging men not only address intimate partner violence but also attend to the social and structural realities surrounding these men's daily lived experiences.

This paper examines the findings from an extensive geographic mapping study of female sex work venues located in the south western Chinese city of Zigong, in Sichuan province. Drawing upon the findings from quantitative research, secondary historical sources and field notes, composed during participant observation, we provide a nuanced portrait of how the operation of sex work can be conceptualised in spatial terms, where 'space' is regarded as something socially constructed and historically contingent. The sex work geographies we analyse hold important implications for prevention work conducted in the region. When the sexual practices between sex workers and their clients are viewed against a wider geographic and historical backdrop, focus shifts from the properties and intentionalities of individuals towards the kinds of spaces where sex work operates, the organisation of which are underpinned by economic forces that have given rise to the rapid proliferation of small urban spaces in contemporary China.
