Abstract

Several morphological similarities, nature of hematophagus and habitat (that is abomasum) similarities between Haemonchus sp. and M. digitatus as worm spacies living in a cow, in the same manner as lacking information of them may cause a misidentification_ Forty cow abomasums from PO race and thirty six cow abomasums from madura race was dissected and observed to find out worms which were suspected to be Haemonchus sp. and M. digitatus. The amount of the infecting worms was counted to reveal its influencelassociation toward cow race. On the result, there was no revealed influence between the amounts of infecting worms to the cow race. M. digitatus was much more found (8657 worms) than Haemonchus sp. (29 worms). The identification was enabled by carmine coloring and electron microscope scanning. The ultrastructure of M. digitatus 's synlophe appeared to be circularly multiple, the H. similis of its cuticle constructed "synlophe" in blunt ridge (it looked like momordica/bitter melon), while its H. contortus constructed synlophe in incisive ridge. By measuring worm's length, a distance of vulva from top posterior and spicula's length in assistance of SEM result, it was concluded that kind of worms infecting cow's abomasums was dominated by M. digitatus and the species of infecting Haemonchus was H. similis. The worm's length of M. digitatus are 28,2 – 31,2 mm for female, 20,3 – 22,1 mm for male. The distance of vulva from top posterior of M. digitatus are 0,34 – 0, 81 mm , and spicula's length are 3,71 – 5,97 mm. While its H. similis 13,1 mm – 16,3 mm are female worm's, 9,7 – 11,7 mm for male, distance of vulva from top posterior are 2,36 – 2,82 mm, length of spicula's are 0,26 – 0,44 mm and the distance tip of spicula's are 0,058 - 0,072 mm.
