| longistrongylus curvispiculum (nematoda: trichostrongyloidea) in free-ranging exotic antelope in texas. | longistrongylus curvispiculum was recovered from free ranging sable (hippotragus niger), addax (addax nasomaculatus) and biesa oryx (oryx beisa) on two ranches in central texas (usa). these nematodes represented a small portion of the total abomasal worm burden dominated by haemonchus contortus. female l. curvispiculum easily could be confused with other ostertaginae, but the spicules of the males were diagnostic. | 1993 | 8355363 |
