Phylogeny of Trypanosomatidae and Bodonidae (Kinetoplastida) based on 18S rRNA: evidence for paraphyly of Trypanosoma and six other genera.
Phylogenetic analysis of 18S rRNA sequences from the families Trypanosomatidae and Bodonidae (Eugelenozoa: Kinetoplastida) was conducted using a variety of methods. Unlike previous analyses using unrooted trees and/or smaller numbers of sequences, the analysis did not support monophyly of the genus Trypanosoma, which includes the major human parasites T. cruzi (cause of Chagas' disease) and T. ...

Purpose: This study designed to examine polarized culture of epithelial cells from human ovidutc and their ultrastracture under polarizing condition. Materials and Methods: The human oviduct was obtained from patients having undergone total hysterectomy and epithelial cells were isolated using collagenase type I.

متن کاملThe genomes of Crithidia bombi and C. expoeki, common parasites of bumblebees
Trypanosomatids (Trypanosomatidae, Kinetoplastida) are flagellated protozoa containing many parasites of medical or agricultural importance. Among those, Crithidia bombi and C. expoeki, are common parasites in bumble bees around the world, and phylogenetically close to Leishmania and Leptomonas. They have a simple and direct life cycle with one host, and partially castrate the founding queens g...
متن کاملEffect of starvation on growth, histology and ultrastructure of digestive system of juvenile red swamp crayfish (Procambarus clarkii Girard)
The present study was conducted to evaluate the effect of 20 d starvation on growth, survival, histomorphology and ultrastructure changes in the digestive system of juvenile red swamp crayfish (Procambarus clarkii). Juveniles were divided into two groups: a food-deprived group and a control group at 9 day after hatch (DAH). Individuals were sampled at 14, 20, 29 DAH. During the 20 d fasting per...
