was conducted in the abattoirs of Metro Manila and<br />
Pangasinan. Out of the total 898 carabao hearts examined,<br />
507 or 56.46% apparently exhibited gross lesions. The<br />
different types of gross lesions were classified and analyzed<br />
based on the cardiac structure involved, sex distribution,<br />
age group and point of origin of the slaughtered animals as<br />
far as the most common lesions (E. poeli) was concerned.<br />
Nodules of E. poeli affecting the aortic opening were the<br />
most commonly encountered lesions representing a<br />
prevalence rate of 35.86%. This was followed by<br />
sarcocystis infection of the myocardium (13.25%), the<br />
reason of which was not known. Male carabaos showed<br />
higher prevalence of cardiac lesion (65.28%) than females<br />
(38.22%), the reason of which was not known. Generally<br />
older animals (16-20 years) were more frequently than<br />
younger ones (11-15 years and 4-10 years). This showed<br />
that age was a factor in the development of cardiac lesions.<br />
Based on the rate of occurrence, carabaos originating from<br />
Mindanao and Nueva Viscaya were most affected by E.<br />
poeli infection while those coming from La Union seemed<br />
to be least affected. No attempt was made to determine<br />
why this was so because the number of animals from the<br />
different regions were not the same in the group s.<br />
Biventricular dilatation with histopathologic features of<br />
cardiomyopathy similar to the reports on man, dogs, cats,<br />
and cattle was also noted. It is suggested that further studies<br />
should be done to determine whether they represent true or<br />
primary cardiomyopathies in carabaos.<br />

DERMATOPHYTOSIS IN A <strong>PHILIPPINE</strong> CARABAO*<br />
J. M. G. Cheng, Student<br />
The case concerns a three year old heifer Philippine carabao<br />
with identification number 1298 housed at the Philippine<br />
Carabao Center, University of the Philippines at Los Baños,<br />
Laguna. The clinical signs apparent during the examination<br />
were generalized skin lesions characterized by scabs,<br />
pityriasis, circular area of alopecia and scaling with central<br />
healing, lesions observed were irregular in appearance<br />
and abrasions in the body and legs were present. Skin test<br />
was made to identify the etiologic agent responsible for the<br />
disease, the laboratory diagnosis used were the direct<br />
microscopic examination of the hair, fungal culture and<br />
identification of dermatophyte species from fungal colony.<br />
Skin test confirmed that the etiologic agent responsible for<br />
HEALTH<br />
the disease was Trichophyton verrucosum, which is the<br />
most common dermatophyte affecting cattle and carabao.<br />
Treatment using Captan® (N-trichloromethyl-4-cyclohexane-1,2-dicarxamide)<br />
fungicide was sprayed all over<br />
the body of the animal for five days.<br />
Keywords: ringworm, dermatophyte, captan, carabao<br />

CARDIAC DYSRHYTHMIAS IN <strong>PHILIPPINE</strong><br />
CARABAO (Bubalus bubalis)*<br />
M. C. Concepcion, Student<br />
Electroradiograms were taken from two hundred (200) Philippine<br />
carabaos using the Apex-Based lead system and 169 (84.5%)<br />
were found to be dysrhythmic. Only 31 (15.5%) had regular<br />
sinus rhythm. A total of 157 supraventricular dysrhythmias<br />
were recorded of which 117 (58.5%) were sinus dysrhythmias,<br />
21 (10.5%) were sinus tachycardias, 17 (8.5%) were sinus<br />
bradycardias and 2 were atrial premature beats. Only one<br />
ventricular dysrhythmia, a ventricular premature contraction,<br />
was recorded. Of the six cases of the conduction disturbances<br />
recorded, 3 were first-degree AV block while the outer three<br />
were second-degree AV block. Accelerated conduction was<br />
seen in 3 of the animals examined. All three had ventricular<br />
pre-excitation. Because of the high incidence of sinus<br />
dysrhythmia in both male and female and in both age groups,<br />
it may be inferred that this type of dysrhythmia is a normal<br />
variant as in dogs and horses although further studies may<br />
have to be done to establish this inference. Similarly, further<br />
studies would be needed to find out the significance of wandering<br />
pacemaker, which was recorded in 26% of the animals. The<br />
significance of the dysrhythmias considered as pathologic in<br />
other animals can be ascertained only by doing extensive<br />
clinical examinations and examining the animals’ heart grossly<br />
and histopathologically following slaughter and correlating the<br />
findings with the electrocadiograms.<br />
