Depending on the type of botulism considered, different tests for diagnosis may be indicated. Foodborne botulism: serum analysis for toxins by bioassay in mice should be done, as the demonstration of the toxins is diagnostic. [62] Wound botulism: isolation of C. botulinum from the wound site should be attempted, as growth of the bacteria is ...

A 2020 study reports that by 2050 global warming could be spreading in the deep ocean seven times faster than it is now, even if emissions of greenhouse gases are cut. Warming in mesopelagic and deeper layers could have major consequences for the deep ocean food web, since ocean species will need to move to stay at survival temperatures. [69] [70]
