“unexpected and alarming” – the longer an animal lives with TB, the more likely it is to infect others!
A buffalo with bovine tuberculosis but no worm treatments has, on average, the potential to infect about one other buffalo. This study found that after worm treatment, a buffalo with this disease had the theoretical potential to infect nine other buffalos. This difference was based on the finding that dewormed buffalo with TB can survive for years, whereas the life expectancy of untreated TB-infected buffalo was much shorter.
What they’re finally get around to saying is “dead third-worlders are likely less infectious than live ones, too. How to achieve that is tricky.”
(It’s easier when I provide the link, eh?)
