چکیده
When viewed from the top, Trichodina is circular; side views of the organism reveal a saucer or dome shape (Fig. 1). It has three rings of cilia (small, hair-like projections) encircling its body and oral cavity, which are used for locomotion and feeding. Its body is supported by a rigid ring of interconnected discs called a chitinoid or denticular ring (Fig. 2). Each disc has a thorn-like inner ray projecting into the center of the ring. Trichodina glides rapidly over the gill and skin surfaces. It is usually found on the gills but also can VI PR October 2003 SRAC Publication No. 4701

متن کاملDirect Molecular Detection and Phylogenetic Tree Analysis of Gastrointestinal Protozoan Parasites (Giardia lamblia, Entamoeba histolytica, Cryptosporidium parvum) from Diarrhea Infection in Kut City of Iraq: A Short Communication
Background: The intestinal tract of human can be infected by protozoan parasites. In this short communication, the stool samples were collected from patients with diarrhea referred to Kut hospital, Iraq, and then the parasites (Giardia lamblia, Entamoeba histolytica, Cryptosporidium parvum) were considered for molecular identification. Methods: Stool samples were collected from 69 patients wit...

متن کاملA Comparative Study of the Common Protozoan Parasites of Clarias gariepinus from the Wild and Cultured Environments in Benue State, Nigeria
A total of one hundred and twenty Clarias gariepinus comprising 30 dead and 30 live fishes were examined for protozoan parasites infestation, sixty each from the wild and a pond (cultured environment) over a period of six months. Ichthyophthirius multifiliis was the most common protozoan parasites found in C. gariepinus from the wild (River Benue) and cultured (pond) environments. These protozo...
متن کاملCanonical and variant histones of protozoan parasites.
Protozoan parasites have tremendously diverse lifestyles that require adaptation to a remarkable assortment of different environmental conditions. In order to complete their life cycles, protozoan parasites rely on fine-tuning gene expression. In general, protozoa use novel regulatory elements, transcription factors, and epigenetic mechanisms to regulate their transcriptomes. One of the most su...
