Glanders:
In August an outbreak occurred in a private stable. The disease was of a particularly virulent type. Two cases were detected at the outset. On "Malleining"
On "Malleining" a further 12 ponies exhibited positive reactions. In investigating possible channels of spread it was found that two ponies had been transferred to one other private stable and one to another. These ponies and all ponies stabled beside them were also "malleined". The result was that the two first mentioned ponies exhibited positive reactions while the latter was negative. Reactors were slaughtered, the premises disinfected and the remaining ponies placed in "working isolation." On re-testing all ponies exhibited negative reactions.
Anthrax:-
Nil.
Rinderpest:-
Early in the year a serious outbreak of a virulent type occurred in a group of cattle sheds in Hong Kong. The total number of animals which became infected was 168 of which 86 cases proved fatal. The unfortunate part of this outbreak was that it commenced a few days before the arrival of large stocks of "Anti-rinderpest Serum" for the owners, with the result that the animals were already in the incubation stage of the disease before serum was administered.
