My guess is that the bacteria in the pigs is completely unrelated to H5N1, because bacteria and viruses are two totally diffferent things. Maybe there is a causal relationship, but I'm merely a layman in these matters.
Same here.
Apparently Strep Suis is very common in pigs, and generally no big deal. Since the outbreak does not seem consistent with what we know about Strep Suis, the suspicion is that the real cause is something else. The presence of Strep Suis could be merely coincidental (assuming it is really there and not just a made up cover story).
The Chinese refusal to share information, including samples, is criminal.
