was ovoid-spherical, 12.86 [+ or -] 2.47 pm long, and 10.45 [+ or -] 2.25 pm wide (n = 55), with a germinal vesicle-like nucleus and a prominent nucleolus.
A single bird was infected with the macrogametocyte of H.
A single bird was found to be infected with the macrogametocyte of H.
falciparum thick smears containing 5620 gametocytes were screened for measuring the gametocyte density for microgametocyte (male) and macrogametocyte (female).
A total of 339 P.falciparum thick smears containing 5620 gametocytes were screened for measuring the gametocyte density for microgametocyte (male) and macrogametocyte (female) and the mean sex-ratio was 0.31 i.e., 3.22 female per male.
Immature developmental stages including small microgametocytes of varied shapes within epithelial cells of the ducts (Figure 4(c)) and round macrogametocytes filled with uniform bluish-pink cytoplasmic granules (Figure 4(b)) were present in impression smears from 2B, 3C, and 6F treatment groups.
(a) Clear, oval to elliptical-shaped fully formed oocysts (black arrow head) and hepatobiliary parenchymal cells (white arrow) from amprolium group at x400, (b) macrogametocytes (white arrow head) and few fully formed oocysts (black arrow head) from sulphachloropyrazine group at x400, and (c) cluster of biliary epithelial cells containing numerous microgametocytes from trimethoprim-sulphamethoxazole group (black arrow).
Renal collecting duct epithelial cells contained intracytoplasmic microgametocytes, macrogametocytes
, and sporulating and sporulated oocysts.
The red chromatin and pigment is more coarse and concentrated in the macrogametocytes
than the microgametocytes.
The size of the parasites was from 1 to 4[micro]m, and based on size and basophilia we identified at least 2 different life-cycle stages on the microvillus border: trophozoites (small basophilic bodies) and macrogametocytes
(larger and less basophilic) (Figure 1).
and microgametocytes were not detected.
The presence of macrogametocytes
in organoid crypt-like structure indicates that these cells have similar characteristics to the native host cells in the rat.
