O-42 - Host-specific wildlife viruses (raccoon-dog amdoparvovirus, bamboo-rat betacoronavirus, civet kobuvirus) were recovered from the market, phylogenetically traceable to southern-China farms
Because these viruses have narrow, known host ranges and were found where their host’s mtDNA was, they indicate that live, productively infected animals of those species (raccoon dog, bamboo rat, civet) were physically present in the market in late 2019, and their phylogenetic links to southern-China (Guangxi/Yunnan) farms trace a wildlife-trade conduit into Wuhan. Recovered from the same D-1 metagenomic reads.

Why this is evidence
Genomes of narrow-host-range wildlife viruses co-located with their hosts show live, productively infected susceptible animals (raccoon dog, civet) were present via the wildlife trade — a precondition H-14 needs and H-15/H-19 do not, and against the ‘no live mammals sold’ premise underlying the amplifier/artifact readings.
