"Although no tubercle bacilli could be detected microscopically in the films
prepared from the centrifugalised deposit in any case, still the films from
specimens B 31, B 35, B 36, and B 39, showed an amount of pus out of all
proportion to the very few cocci which could be detected microscopically."
It will be noticed that four of the cows out of the 10 showed an excessive
amount of pus in the milk and the probability is that some chronic form of
inflammation exists in the udders of these cows set up by excessive stripping
habitually practised in order to stimulate and increase the supply of milk from
the cows. These are the kind of udders that are likely to become infected with
tubercle bacilli, and where the bacilli find lodgment if they have not already
done so.
Copies of these reports were sent to the Local Government Board and the
London County Council.
