Septicaemia Haemorrhagica :- Six cases among cattle occurred throughout the year. This disease is due to a specific Bacillus and it affects various organs of the body, as its name implies it is of a septicaemic nature.
Tuberculosis :- Only one case occurred. Native Chinese cattle seem to possess a certain amount of immunity to this disease and it is very rarely seen among them although it is, I believe, fairly prevalent among the native human species.
Miscellaneous :- Jaundice fever, Oedema, etc. Cases of these diseases occasionally occur and of course the carcases are invariably condemned.
Glanders :- There were no cases of Glanders, due to the Mallein test introduced by Captain Oxspring and Mr. Mackenzie C.V.S., whose efforts horseowners in Hongkong I am sure appreciate. At a Northern Port, two months since, out of 40 valuable racing ponies imported from Mongolia, 8 had to be destroyed through an outbreak of Glanders. Since then it has been made compulsory to apply the Mallein Test.
Rabies :- In all there were five cases of Rabies in dogs in 1925; they were distributed as follows :- 1 in each of No. 2, 3, 4, and 16 Health districts and 1 in the New Territory. No dog poisoners are officially employed here, neither is there a muzzling order in force, but animals are to some extent segregated in areas as they are not allowed to be landed on or removed from Hongkong without a written permit from the Colonial Veterinary Surgeon. This measure of control is of decided value. Owing to the situation of the New Territory there is always the danger of infected animals coming through from the interior.
Owing to a very bad outbreak of Rabies in Japan, Umeno and Doi carried out a system of vaccination as a method to control the disease in dogs. After experimental work they concluded that it was possible to immunize dogs against rabies by means of one subcutaneous injection of glycerinated fixed virus which had been attenuated by the addition of Phenol. This method was put to a practical test and large numbers of pet dogs in certain districts were given one dose of vaccine.
Umeno and Doi state :- There were 31,307 dogs vaccinated in Japan, of which number there was only one case of vaccination loss, and one in which the vaccination could not be regarded as effective enough; there were many cases of rabies among the unvaccinated dogs. It will be seen from the above that this prophylactic measure has been proved of the greatest value in combating the spread of this disease among animals.
Osteoporosis, Bighead or Miller's Disease :- This is by far the most serious disease that stock owners of Hongkong have to deal with. It is a general disease of the bones which develops slowly and progressively and is characterized by the absorption
