SYNOPSIS.The nameNebela tuberculatacomb. nov. is proposed for the testate ameba formerly known asDifflugia tuberculata(Wallich, 1864) Archer, 1867. The generic reassignment is based upon the test construction material which is shown, by electronmicrographs and X‐ray diffraction, to be autogenous regular and irregular silicious rods. A brief history of the animal is recounted utilizing works of several authors who have encountered the ameba over the last centur

摘要:

SYNOPSIS.Eimeria tenggilingiis described from the pangolin or scaly anteater,Manis javanica, in Malaysia. The spheroid to subspheroid oocysts average 18.9 × 17.8 μm. The oocyst wall is composed of 3 layers, each ∼ 0.6 μm thick. The 2 outer layers are striated and yellowish green. The inner layer is dark brown. One or 2 polar granules are present, but an oocyst residuum is absent. Ellipsoid sporocysts average 12.4 × 6.2 μm. A sporocyst residuum is present. This is the firstEimeriaspecies reported from a host in the order Pho

SYNOPSIS.Toxoplasma ranaesp. n. is described from the brain of a leopard frog,Rana pipiens, probably from Mexico. Its pseudocysts were 72(55‐106) × 48(29‐70) μm in fixed sections. They contained an average of ∼ 4,000 slightly curved elongate zoites measuring 4–5 × 0.5 μm, with a central, spherical, vesicu

摘要:

SYNOPSIS.Five species ofLeptotheca, one new, were found in the macrourid fishes and the sablefish,Anoplopoma fimbria. Those species which were geographically widespread in numerous host species showed little variation. TwoLeptothecaspecies were found both in the gall bladder and urinary bladder/kidney.

摘要:

SYNOPSIS.The ultrastructure of the mitochondrion during transformation ofLeishmania donovanifrom amastigote to promastigote stages was studied by morphometric analysis. There was a slight but significant decrease in relative mitochondrial volume (Vvli) during transformation. This decrease was linear with time for at least 27 hr. No change in relative lipid inclusion volume (Vvli) was observed during transformation. The ratio of inner to outer mitochondrial surface membrane densities (Svmii:Svmio) also remained unchanged. Although the relative number of cristae remains unchanged after transformation, there is an increase in cristae number in the portion of the kinetoplast opposite the flagellum.

摘要:

SYNOPSIS.A haplosporidan parasite belonging to the genusMinchiniawas found in 4 of 1,438 oysters,Crassostrea gigas, collected from the Republic of Korea. Multinucleated vegetative stages were present in the infected oysters. Spores found in one of these oysters were acid‐fast and had operculate characteristics of the genusMinchini

SYNOPSIS.Egestion of carmine particle‐containing food vacuoles from the cytoproct ofTetrahymena pyriformishas been analyzed by high‐speed cinemicrography. The vacuole may enter into position in the cytoproct ∼ 7 sec before ejection, and forms a distinct bulge beyond the outline of the cell surface for over 2 sec prior to ejection. The ejection process itself requires 20–
