The African trypanosomes ADP-ribosylation factor 1 has species-specific motif signatures and is developmentally regulated

Small GTP-binding proteins of the ADP-ribosylation factor (Arf) family are essential for vesicle formation, intracellular and membrane trafficking and signal transduction. We have cloned and characterized the homologue of Arf1 fromTrypanosoma b. brucei, Trypanosoma evansi, Trypanosoma congolense andTrypanosoma vivax. The African trypanosome Arf1 cDNA contains an open reading frame of 546 base pairs,...

Study on ultrastructure of Leishmania major and Lizard leishmania

We compared ultrastructure of Lizard Leishmania and Leishmania majorpromastigotes by electron microscope. Leishmania major (MRHO/R64/Nadim1) and Lizard leishmania promastigotes were mass cultured, collected by centrifugation and washed by PBS buffer three times, the ultrastructural features of both Leishmania promastigotes were observed by transmission electron...

Comparative histological features of the pancreas in fruit-eating bat (Eidolon-helvum) and pangolin (Manis tricuspis)

Mammals have varying histological features in their gastrointestinal tract to enable them cope with their dietary preferences.  Fruit-eating bat (Eidolon helvum) is a frugivore while Pangolin (Manis tricuspis) is an insectivore, pancreases of the two animals were investigated histologically to know if the histological features of pancreas could have any implication on their dietary preferences. The animals...
