| Summary: | The study was conducted to detect and compare the percentage frequency
occurrence of microcyst count of Sarcocystis species in muscles of farm animals.
The tongue, diaphragm, esophagus and heart were collected from freshly
slaughtered backyard-reared cattle, goat and pig. The muscle samples were
subjected to acid digestion technique using trypsine for microcyst counting. The
highest percent frequency occurrence of microcyst count among animals were
observed in goats and cattle with 16.93% each, followed by pigs (16.88%).
Statistically, there was no significant difference (p>0.05) among the microcyst
count in animals. In terms of organ samples, the highest percent frequency of
occurrence of mirocyst count was found in the diaphragm (17.03%), followed by
tongue (16.92%), esophagus (16.90%) and heart (16.79%). Statistically, there was
no significant difference (p>0.05) among the microcyst count among organs.
Potential variation of Sarcocystis species is suggestive based on the cyst size and
its cyst wall. For goat, the potential Sarcocystis species is S. hircicanis in which
the observed cyst size ranges from 80–450 x 40–250 μm and the cyst wall size
ranges from 5–35 μm. For pig, the potential Sarcocystis species can either be S.
meischeriana or S. suihominis in which the observed cyst size ranges from 65–
650 μm and the cyst wall size ranges from 3.75–12.5 μm. For cattle, the potential
Sarcocystis species can either be S. hominis or S. levinei in which the observed
cyst size ranges from 150-400 x 145-150 μm and the cyst wall size ranges from
10-11.25 μm. In conclusion, Sarcocystis spp. was detected in all animals studied.
However, the distribution pattern of microcysts in different animals and different
organs varies. All cysts detected were in proliferative phase. The proliferating
Sarcocystis cysts found in the muscle samples were identified as potentially
Sarcocystis species: S. hircicanis for goat, S. meischeriana and S. suihominis for
pig, and S. hominis and S. levinei for cattle. |
