THE PHILIPPINE WATER BUFFALO

All animals are apparently healthy except for their lice
infestations. Their previous management practice was
maintained. The percentage reduction was monitored using
the 10-minute count before and after treatment every week
for three (3) consecutive weeks. In vivo experimentation
showed that the tobacco pour on method using oil emulsion
was more effective than the spray method although, both
methods are similar (p>0.05). Percentage reduction
decreased after first week of treatments with an increasing
trend after three (3) weeks post treatment (in vivo). Tobacco
and makabuhay in oil-emulsion were most effective in with
a percentage reduction of 45.91 and 79.67 respectively.
Neem and tubli in vivo oil-emulsion showed a negative
percentage reduction after three (3) weeks post-treatment.
Tobacco mixture in distilled water using the spray method
obtained a percentage reduction of 15.83 after three (3)
weeks post-treatment. Results show that tobacco,
makabuhay, neem and tubli are potential source of
ectoparasiticide against Carabao louse. Like all chemically
based medicines, herbal plants should also undergo a
battery of experimental procedures to determine their total
pharmacological profile. The plant’s many uses still remain
to be explored.

HISTOLOGICAL DISORDERS OF THE INTERNAL
REPRODUCTIVE ORGANS OF SLAUGHTERED
PHILIPPINE CARA-COW (Bubalus bubalis)*
D. T. Rodulfo, Student
Fourteen pathological cases of the internal reproductive
organs of slaughtered Philippine cara-cows (Bubalus
bubalis) were studied histologically. No literatures on
histopathological disorders of the internal reproductive
organs of cara-cows were yet available so that similar
histopathological cases occurring in the bovine species as
found by veterinary pathologists were used as bases for
comparison. Normal slides of the different organs were
used as basis for determining cellular changes as references
in veterinary histology. Of the pathological disorders studied,
follicular cysts is the most common as surveyed followed
by the paraovarian cyst, cervicitis, hydrosalphinx, cystic
glandular hyperplasia cystic corpora lutea, hypoplasia and
adhesions. The least common disorders were mucometra,
tumor, cervical cyst, pyometra and ovarian hematoma.
No correlation between these histopathological disorders

ABSTRACT OF RESEARCHES ON
THE PHILIPPINE WATER BUFFALO
and that of infertility was done since no breeding history
could be obtained. It is presumed in this study however
that the animals used in this study had been slaughtered on
account of their unproductiveness. Nevertheless, it was
found in this study and in previous studies that paraovarian
cyst did not affect the fertility of the animal and that cystic
corpora lutea are known to occur in normally fertile animals.
Others might have caused infertility while cervicitis, cystic
glandular hyperplasia, uterine tumors and generalized
adhesion might have caused infertility if such conditions
were extensive.

PATHOLOGIC CHARACTERIZATION AND
BACTERIAL PROFILE OF THE LIVER AND
ASSOCIATED STRUCTURES OF SLAUGHTERED
PHILIPPINE CARABAO (Bubalus bubalis)*
M.C. N. Rundina, Student
This study was done to device a sequential way of
inspecting the liver of the Philippine carabao and to correlate
the gross lesions found in the organ and from its associated
structures with the histopathologic findings, as well as the
bacteria isolated. Cirrhosis was the predominant lesion
observed in the liver. Fibrous tags, red black mottling and
abscesses were also encountered. Corynebacterium sp.,
Staphylococcus aureus, Corynebacterium
pseudotuberculosis, Rhodococcus equi, Psedomonas
aeruginosa, Pseudomonas aeruginosa, Pasteurella
haemolytica, Streptococcus sp., Actinomyces pyogenes,
Enterobacter aerogenes, Escherichia coli, Edwardsiella
ictaluri, Salmonella sp. and Citrobacter freundi were the
bacteria isolated from the liver. Bacteria isolated from the
hepatic lymph node included Corynebacterium sp.,
Staphylococcus aureus, Actinomyces pyogenes,
Corynebacterium pseudotuberculosis, Pasteurella
haemolytica, Rhodococcus equi, Psedomonas aeruginosa
and Enterobacter aerogenes. Corynebacterium sp.,
Escherichia coli, Rhodococcus equi, Salmonella sp and
Edwardsiella ictaluri were isolated from the bile. It is the
purpose of this study to device a sequential way of
examining the liver of the Philippine carabao so as not to
miss out any lesion. When conducting bacterial isolation
from the liver, particularly of liver fluke affected animals,
contamination of the organ with bacteria brought by the
migrating larvae should be always be considered. Further
