Argument of the work
Contagion runs sideways. Bacteria traffic plasmids across species lines; retroviruses stitch themselves into germlines; patent law tries to fence the traffic and fails. Luciana Parisi's "Biotech: Life by Contagion" ([Theory, Culture & Society 24, 2007](https://monoskop.org/Luciana_Parisi)) [w0] takes this lateral transfer as its object and refuses the partition between organic life and informatic capital that most critiques of biotech still assume.
The move is to treat contagion as the operator of both biology and markets, then ask what follows. If horizontal gene transfer is how bacterial phyla actually evolve, then vertical descent is a local case of a more general traffic. If biotech capital replicates by licensing, splicing, and recombining code across jurisdictions, it is not metaphorically viral. It uses the same topology. Parisi collapses the two registers into a single diagram of infectious transmission across strata.
This closes a familiar escape route. The standard bioethics position wants life on one side, information and capital on the other, with contamination to be policed at the boundary. Parisi's essay removes the boundary. Contagion is already the medium in which phyla, markets, and molecular engineering co-compose. The political question shifts from how to protect life from commodification to how to read a field where commodification and symbiogenesis share a mechanism.
The argument extends a line running through Sadie Plant's writing on bacterial sex and distributed replication, and through CCRU's wider interest in lateral, sub-personal transmission. Where Plant's *Zeros + Ones* mapped the connection between women, machines, and viral spread, Parisi pushes into the molecular and economic layers underneath. The hyperstition frame is audible: contagion is a real abstraction, a vector that rewrites the body it passes through. Amy Ireland's later work on feminine exit and xeno-transmission picks up the same thread from a different angle. Urbanomic's ongoing publication of Parisi-adjacent material on [lesbovampiric contagion-libido](https://www.urbanomic.com/tag/lesbovampiric-contagion-libido/) [w2] marks the lineage.
What the essay authorises is a way of reading biotechnology that does not bottom out in horror at the market or nostalgia for untouched nature. Both responses assume the partition Parisi has dissolved. If life has always been contagious (bacterial, symbiogenetic, lateral) then biotech is an intensification of an existing condition, not a fall from one. The stakes are methodological. Critique has to work at the level of vectors and rates rather than boundaries and essences. That reframing is what the piece delivers, and it is why Parisi's later work on abstract sex and on computation reads as continuous rather than as a change of subject.
How to read this
For Parisi - Biotech- Life by Contagion, start with the opening discussion of bacterial sex and the biotech market. Those pages establish the text's core operation quickly.
For Parisi - Biotech- Life by Contagion, read for the link between transmission and abstraction. The essay is strongest when life-process and commercial process start to look continuous.
Argument map
Primary claim
The central claim is that biotech no longer works by perfecting bounded organisms. Life becomes contagious, transversal, and informational, with bacterial sex serving as the exemplary process of transmission across species boundaries.
The work's mechanism
Parisi joins genetic engineering, bacterial exchange, and market capture to show how life is reorganized by non-copulatory transmission and data-rich intervention. Contagion is treated as the operative mechanism, not a metaphor.
What this work claims
That matters because this page gives the control section one of its clearest and most rigorous formulations. Virotechnics becomes thinkable here as a mode of life, commerce, and distributed mutation.
Publication context
This work is surfaced here through the Control, Virotechnics, and Swarm Systems section of the archive. The edition treats it as a text that circulated within a larger scene of lectures, web fragments, and later commentary rather than as a freestanding classic.
The public page keeps the interpretive layer, the supporting text page, and the original file paths distinct, so readers can orient themselves without mistaking the edition for a substitute full-text republication.
How this work reaches the archive
The page uses the canonical extracted text as its reading layer while preserving the original file paths as the archival source of record.
The supporting text page draws on texts-extracted/Parisi - Biotech- Life by Contagion.txt while preserving 1 source file path(s) as the archival source of record.

Bacterial sex is the transmission of information across phyla and lineages. Bacteria (non- nucleated bounded cells) continuously modify their genetic make-up whilst infecting new cells. This sex by contagion has become fundamental to biotech’s task of redesigning life.

History · paragraph 1
Biotech Life by Contagion Luciana Parisi Introduction I N 1994, the merging of biotech corporations Merck & Co. and Washington University gave birth to Genbank, which launched, for the first time, clones on the market. Since then, clones have become part of the commercial world of genetic engineering, DNA maps and, recently, pharmacogenomics.1 In particular, the reproduction of life – from cells to embryos – without sexual mating has entered the biotech market.
