Region I with 13/40 or 32.50% followed by Region XII<br />
with 13/42 or 30.95% and Region IX with 3/13 or 23.08%.<br />
Occurrence of positive reactors per region was highly<br />
significant (P < 0.01). There was no significant difference<br />
between species occurrence of positive reactors (P =<br />
0.31). For both species, the occurrence of more positive<br />
reactors in males (16.3%) than in females (10.9%) was<br />
statistically significant (P < 0.05). In carabaos, there was<br />
a higher occurrence of positive reactors in the 9 to 10 age<br />
group with 7/25 or 28% followed by animals older than 10<br />
years with 36/166 or 21.69% and the 8 to 9 age group with<br />
9/44 or 20.45%. In cattle, more positive reactors were<br />
found in the 5 to 6 group with 12/33 or 36.36, followed by<br />
4 to 5 age group with 7/37 or 18.92% and the 9 to 10 age<br />
group with 6/32 or 18.75%. There was a direct correlation<br />
between the occurrences of positive reactors to the age<br />
group to which they belong (P < 0.01). This study was<br />
able to establish the presence of Brucella agglutinins in<br />
carabaos and cattle from the different regions in the<br />
Philippines and hence, is the first study to document the<br />
occurrence alone and thus, a complementary test should<br />
be used to confirm the present findings. A concerted effort<br />
must be made to really determine and establish the actual<br />
presence of brucellosis in livestock. Such a programme<br />
would greatly aid in the control and eventual eradication of<br />
the disease.<br />

BACTERIOLOGIC PROFILE OF <strong>THE</strong> VAGINA AND<br />
UTERUS OF NON-PREGNANT <strong>BUFFALO</strong>-COWS IN<br />
SELECTED REGIONS OF <strong>THE</strong> <strong>PHILIPPINE</strong>S*<br />
M. T. T. Balassu, Student<br />
A bacteriologic survey was made on the uterus and vagina<br />
of 13 fertile and 27 infertile buffalo-cows. A sterile cotton<br />
swab and a locally-made endometrial swab instrument<br />
were used to collect vaginal and uterine samples,<br />
respectively. Majority of the vaginal samples were positive<br />
for microorganisms. A greater proportion of these samples<br />
yielded mixed rather than pure cultures of bacteria. The<br />
most frequently isolates were streptococci, corynebacteria<br />
and staphylococci. Non-specific uterine infections were<br />
found to be present even among fertile buffalo-cows.<br />
Staphylococci, streptococci and corynebacteria were the<br />
predominant bacterial species isolated from these animals.<br />
Among infertile buffalo-cows, the incidence of non-specific<br />

uterine infections was higher in repeat breeders than in<br />
anestrus animals. Mixed uterine infections were found to<br />
be more frequent among repeat breeders than anestrous<br />
buffalo-cows. The most commonly isolated organisms,<br />
however, were the same for both groups and these include<br />
the streptococci and corynebacteria.<br />

FIELD TRIAL OF HEMOSEP (Pasteurella multocida<br />
TYPE B) VACCINE IN <strong>PHILIPPINE</strong> <strong>BUFFALO</strong>ES*<br />
E. M. Battad, Student<br />
A vaccine against hemorrhagic septicemia from a crude<br />
capsular extract of P. multocida was tested on 7 buffaloes.<br />
Antibody titers were monitored on day 0, 28, 61, 89, 120<br />
and 150 using IHA test on collected serum samples. There<br />
was significant increase in the serum antibody titer until the<br />
end of the study period (day 150). There was however, no<br />
significant difference in serum antibody titer between those<br />
given a shot at day 0 and those given at day 0 and 28.<br />
Further study can be done on when is the best time to give<br />
the second (booster) shot of the vaccine. The immune<br />
serums of the vaccinated buffaloes were used in the passive<br />
mouse protection test. Results show that the sera of the<br />
three vaccinated buffaloes used were able to protect mice<br />
from P. multocida type B infection. Based on these results,<br />
the vaccine seemed to have good potential in protecting<br />
buffaloes from hemorrhagic septicemia.<br />
