More broadly, it shows the extent of humans contaminating the urban environment with antibiotic resistant bacteria capable of causing disease in a range of hosts, but that thankfully, there are limits to spillover in rural populations.

Given predictions that fish consumption will increase, more whole genome sequencing of S. aureus in aquaculture is needed to understand how S. aureus enters these environments and to mitigate future risk to fish and human health.

Our results support the presence of S. aureus in fish being due to spillover from other hosts, rather than adaptation of S. aureus to aquaculture or fish populations.

These isolates were clustered (CC45), but genomic diversity was large, suggesting the fish repeatedly acquired it from a source. The presence of a φSa3 prophage with a human immune evasion cluster, plus close relatives from humans strongly suggests a recent history within humans.

While our sampling methods readily detected S. aureus from the external and internal organs of a London farmed fish, we did not detect S. aureus in any wild Highland fish. We sequenced 12 S. aureus isolates from the farmed fish to find out where they may have come from.
