A PRELIMINARY STUDY ON THE INCIDENCE OF
SALMONELLA SPECIES IN THE FECES OF
PHILIPPINE CARABAOS*
E. H. Abellanosa, Student
A total of 300 individual fecal samples from Philippine
carabaos, coming from seven provinces and brought for
slaughter at the National Abbatoir, Marulas, Valinzuela,
Bulacan, were bacteriologically examined for the presence
of Salmonella sp. All of them proved negative for Salmonella
organisms. From this limited study, it can be concluded
that Salmonella organisms are not present in Philippine
carabaos. These animals, therefore, do not appear to be a
potential source of Salmonella infection in man. A further
study of this problem is thus needed in order to confirm the
above findings.

A PRELIMINARY STUDY ON THE CLINICAL
EFFECTS OF AZAPERONE AND CHLORPERIDOL
ON CARABAOS (Bubalus bubalis) RAISED IN THE
PHILIPPINE CARABAO CENTER*
G. P. Ables, Student
The effects of azaperone and chlorperidol were studied in
carabaos raised at the Philippine Carabao Center. The
drugs, which belong to the butyrophenone group of
tranquilizers, were given at 2 dose levels (1 mg/kg BW or
2 mg/kg BW). The effect of azaperone at 1 mg/kg BW in
carabaos was slight sedation after 30 - 45 minutes of
administration. There was a marked increase in the pulse
rate and a decrease in temperature, while not having major
changes on respiration. The higher dose (2 mg/kg) of
azaperone in carabaos caused initial excitation and
restlessness followed by slight sedation. There were similar
effects on the pulse, rate and temperature (PRT) as that
with the low dose of azaperone. Chlorperidol at 1 mg/kg
BW in carabaos caused sedation after an average of 80
minutes from drug administration. The drug had similar
effects on the PRT as that of azaperone. Chlorperidol at a
high dose in carabaos also caused excitation and
restlessness. There were similar effects on the pulse rate
and temperature as with azaperone and the low dose of

chlorperidol. However, the respiratory rate increased due
to the animal’s restlessness. From the results of the study,
the low dose of azaperone (1 mg/kg BW) maybe effective
in causing tranquilization in carabaos. However, its long
induction period (30 – 45 mins.) presents a disadvantage
in emergency cases requiring surgery. Although this is just
a preliminary study on the effects of the readily available
butyrophenones, the information generated could help the
field veterinarian in his decision-making. It is recommended
that azaperone and chlorperidol be assessed during surgical
procedures on carabaos to determine the drug’s usefulness.

A SEROLOGICAL SURVEY FOR Brucella abortus
ANTIBODIES IN THE BLOOD OF NATIVE
CARABAOS USING THE RAPID PLATE
AGGLUTINATION TEST*
F. L. Abrena, Student
A serological test using the rapid plate method was
conducted on native carabaos for the presence of Brucella
agglutinins. Out of 130 animals, 19 or 14.61 per cent gave
a diagnostic liter while 111 animals or 85.03 per cent were
negative to the test. Only 3 or 2.30 per cent of the blood
tested gave a positive result and sixteen animals or 12.30
per cent were found to be suspicious. Although the test
was done on a limited number of animals which might not
justifiably represent the whole carabao population in this
country, the results strongly indicate the presence of
brucellosis among Philippine carabaos.

A SURVEY OF LEPTOSPIRAL ANTIBODIES IN
CARABAOS FROM TEN SELECTED CARABAO
CENTERS IN THE PHILIPPINES*
D. M. Abrigo, Student
A total of 129 serum sample from different carabao centers
in the Philippines were tested against leptospirosis using
the Microscopic Agglutination Test (MAT). Twelve leptospiral
