studies are necessary to find possible correlation regarding<br />
the liver pathology and its associated bacteria particularly<br />
in the Philippine carabao. Fasciola sp. must always be<br />
considered. More reliable information may be derived from<br />
doing anaerobic culture of liver fluke affected livers if the<br />
purpose of the study is to find a correlation between<br />
fasciolosis and its associated bacteria.<br />

A PRELIMINARY SEROLOGICAL SURVEY OF<br />
LEPTOSPIRAL INCIDENCE IN <strong>PHILIPPINE</strong><br />
CARABAOS BY PLATE SCREEN AND RAPID PLATE<br />
TEST*<br />
D. O. Tumibay, Student<br />
A serological test of Philippine carabaos for the presence of<br />
antibodies against Leptospira pomona and L.<br />
icterohemorrhagiae, was conducted. Only 4 out of 150<br />
(2.66%) carabaos were positive in plate screen test, and<br />
2 (1.33%) were positive in rapid plate test. The results,<br />
although inconclusive, indicated the presence of<br />
leptospirosis among Philippine carabaos.<br />

CLINICO-PATHOLOGIC OBSERVATIONS IN A<br />
CARACALF (Bubalus bubalis) INOCULATED WITH<br />
B:2*<br />
K. C. Villanueva, Student<br />
One healthy male unvaccinated caracalf was<br />
experimentally inoculated subcutaneously with 2-ml of 9.91<br />
x 10 4 cfu of. Three phases of the septicemic disease were<br />
observed. The increase in temperature (phase 1) occurred<br />
at 4.4 h post-infection, respiratory distress (phase 2) also<br />
at 4.5 h post-infection, and the recumbency or terminal<br />
phase (phase 3) was manifested 8 h post-infection. The<br />
duration of the clinical course was 15 h. At necropsy,<br />
subserous petechial hemorrhages throughout the visceral<br />
organs and presence of blood-tinged fluid were observed<br />
in the thoracic and abdominal cavities. Histopathology<br />
HEALTH<br />
showed vascular changes characterized by marked<br />
hyperemia, congestion, hemorrhages, edema, and fibrin<br />
formation. These were observed in the lungs, spleen, kidney,<br />
heart, lymph nodes, intestine, tongue, and liver.<br />

PREVALENCE OF AGGLUTININS AGAINST<br />
Pasteurella multocida IN CATTLE AND CARABAOS<br />
IN SELECTED REGIONS OF <strong>THE</strong> <strong>PHILIPPINE</strong>S*<br />
Z. C. O. Zabala, Student<br />
Three hundred nineteen Carabao serum samples and 312<br />
cattle serum samples were collected from a number of<br />
slaughterhouses and farms in the different regions in the<br />
country. The sera were tested against different serotypes<br />
of Pasteurella multocida by the rapid plate agglutination<br />
test. The results showed the predominance of type A over<br />
type B both for cattle and carabao. There was a prevalence<br />
rate of 9.2% for serotype A agglutinins and 1.7% for<br />
serotype B agglutinins. None of the serum samples tested<br />
positively against serotypes D and E. Based on the limited<br />
number of serum samples tested in this study, it appeared<br />
that the predominant serotype of P. multocida to which<br />
Philippine cattle and carabao are exposed to is type A.<br />
However, the focus of the present vaccination against<br />
pasteurellosis in our country is against type B only.<br />
Therefore, there is a need to conduct more thorough<br />
epidemiological studies to determine the real extent of P.<br />
multocida type A infection in cattle and carabaos. Results<br />
of such studies will help in formulating better control<br />
measures against pasteurellosis. Perhaps, the inclusion of<br />
serotype A is necessary in the present vaccine.<br />
