A clinincal evaluation of abdominal paracentesis in the horse. This paper evaluates the usefulness of abdominal paracentesis as a diagnostic aid in abdominal disease in the horse and in particular considers whether or not it can be effectively utilised as an indication for surgical intervention in cases of colic. The results are based upon peritoneal fluid samples collected from 20 normal horses and from 20 cases of colic and peritonitis. Peritoneal fluid was collected from standing horses by inserting a bovine teat cannula into the horses abdomen through the linea alba after desensitisation of the skin on the ventral midline with local anaesthetic. Usual...
Cardiac monitoring during exercise tests in the horse. 3. Changes in the electrocardiogram during and after exercise. Changes that occur in the equine ECG during and after exercise have been described and compared with resting ECG's obtained from the same horses. When the speed of work equals or is greater than "three-quarter pace" (i.e. "even time" or 200 metres in 15 seconds) the high heart rates developed cause the loss of ECG waveforms that are readily discernible at rest. Although differences in the waveforms between horses with normal and abnormal resting ECG's have been observed, the more definitive useful information is the fact that abnormal horses showed significantly higher heart rates than normal ...
Osteodystrophia fibrosa in horses at pasture in Queensland: field and laboratory observations. Horses grazing manily Cenchrus ciliaris and/or Panicum maximum var. trichoglume pastures on over 30 properties in southern central Queensland developed lesions of osteodystrophia fibrosa. Horses on individual properties in coastal Queensland grazing Setaria anceps, Brachiaria mutica or Pennisetum clandestinum also developed the disease. Ill-thrift, lameness, and fibrous swellings of nasal bones, maxillae and mandibles were observed. Calcium and phosphorus levels of pasture were normal but all the above pasture species contained oxalates which were suspected of causing the disease.
Cardiac monitoring during exercise tests in the horse. 2. Heart rate responses to exercise. Data on resting heart rates, pre-exercise heart rates, the anticipatory rises before exercise, the influence of speed of work and recovery heart rates have been presented. Some observations on differences in the heart rate response on slow and fast working days are also recorded. In conformity with other workers, a linear relationship between heart rate and working speed within the range of 400-800 metre/min was observed. When the speed of work was between 400-800 metre/min, horses with resting ECG's classed as abnormal had significantly higher heart rates than those regarded as normal. It was...
Immunity to Streptococcus equi. Using the long chain test, and in some cases the bactericidal test, to measure antibody, the development of the immune response in horses to Str. equi has been followed. Long chain indices in excess of 5.0, accompanied by strong bactericidal capacity, were recorded in serums after the full 3-dose immunisation course with a commercial vaccine. The full course elicited the most satisfactory antibody titres declined within the 12 month post-vaccination period, thus providing support for the recommendation that yearly booster doses should be administered. The immune response in horses during 2 str...
Cardiac monitoring during exercise tests in the horse. 1. Magnetic tape recording in preference to radio-telemetry. Different techniques for monitoring cardiac responses to exercise in the horse have been described and evaluated. For experimental work of this type in a normal training and racing environment, the electrode system described when used with a portable magnetic tape recording system provided the best means of obtaining useful and reproducible data.
Investigation of equine infectious anaemia in Queensland using gel diffusion. An antigen for the gel diffusion test for equine infectious anaemia (EIA) was prepared from the spleen of a horse experimentally infected with the CQ strain of the virus. The antigen produced a single, distinct line of precipitation when tested against a range of known positive serums, and did not react with pre-inoculation and known negative serums. Extracts prepared from uninfected spleens displayed no reaction when similarly tested. Serum from 34 of 451 Queensland horses contained detectable levels of antibody to EIA virus. The positive serums were from horses in widely separated areas of t...
Inheritance of a lethal immunodeficiency disease of Arabian foals. A fatal syndrome of certain Arabian foals which begins at about 25 days of age (range 14 to 46 days) and which runs a course of about 23 days (range 13 to 42 days) is described. The syndrome, which affected 17 foals on a single farm is further characterised by pneumonia, in some instances by dermatitis (dermatophilosis) and other infections, together with a progressive decline in health till death at about 49 days of age (range 34 to 77 days), despite intensive therapy. Four of the foals, on histopathological evidence, had adenviral pneumonia, in 2 foals there was histopathological evidence of...
Snakebite in the horse. Four cases of snakebite in horses are presented. Diagnosis was made on clinical signs in all, plus fang punctures in 2 cases. Tiger snake antivenene was used in the treatment of 2 patients and these recovered rapidly. Of the 2 in which antivenene was not used, 1 severely affected horse died. The clinical signs which were observed were those of progressive general paralysis and were entirely referable to the neurotoxic component of the venom.
The relation of clinical and bacteriological findings to fertility in thoroughbred mares. Day (1939) recorded 95% fertility in wild
ponies, but in heavy horses it was only 52%
and in thoroughbreds 68%. Variation of fertility was stated by Anderson (1922) was not due
to disease or physiological malfunction, but to
highly artificial methods of mating. In New
Zealand, Bain (1948) recorded the fertility of
mares in 1944 as 61%. MahaiIey (1950) made
a survey in Western Australia and found fertility
rates which varied from 17% to 50% before
veterinary assistance was obtained.

1949) revealed no evidence of any progress in

Phycomycotic granuloma in horses in the Northern Territory. Under the title “Equine Granuloma in the
Northern Territory of Australia” Lewis (1914)
gave an account of a disease of horses otherwise
known as “swamp cancer”. A variety of superficial sites are affected but these are rarely above
the level of the shoulder joint and principally
involve the lower legs and the ventral aspect of the
thoracoabdominal wall. The lesions on the legs are
granulating ulcers, those on the body are subcutaneous swellings and both are characterised by
the presence of conspicuous necrotic cores or
“kunkers” in the inflammatory tissue.
