The structural and signaling components of the actin cytoskeleton from available genomes of three Entamoeba species, E. histolytica, E.dispar and E. invadens, have been annotated manually and compared systematically. These protein families include the actin superfamily, actin nucleators, calponin-related actin-binding proteins (ABPs), gelsolin-related ABPs, myosins, small GTPases and their regulators, as well as phospholipid signaling regulators.from Anaerobic Parasitic Protozoa: Genomics and Molecular BiologyFurther reading:Anaerobic Parasitic ProtozoaAcanthamoeba: Biology and PathogenesisLeishmania: After The GenomeFull range of bo...

Loftus et al. published an annotation of the draft genome assembly in 2005. However, subsequent identification of assembly artifacts and the availability of additional sequence and functional data made necessary a thorough revision of its entire sequence and annotation. The genome of E. histolytica has now been re-assembled and re-annotated, incorporating significant structural and functional modifications to existing gene models. The new 20 million basepair genome assembly contains 8,160 predicted genes; known and novel transposable elements have been mapped and characterized, functional assignments have been revised and updated, and addit...

Chapters are written from a molecular and genomic perspective and contain speculative models upon which future research efforts can be based. Topics include: the genomes of Entamoeba histolytica, Trichomonas vaginalis, Giardia and other diplomonads; the cytoskeletons of Entamoeba histolytica, Giardia lamblia and Trichomonas vaginalis; genomic analyses and manipulation of gene expression in Entamoeba histolytica; nuclear and chromosomal structure and replication in Giardia; and the mitochondrion-like organel...

It is not possible to distinguish these organisms by morphologic grounds unless you see ingested RBCs in the trophozoites which are strongly suggestive of E. histolytica. Since there are none present in these images, this specimen should be reported out as E. histolytic/E. dispar, with a recommmendation for correlation with clinical presentation and additional lab testing such as serology, stool antigen testing, and/or stool PCR. Clinically, E. histolytica is a known pathogen, and can cause bloody diarrhea and disseminated disease. E. dispar, on the other hand, is NOT thought to cause disease. Since E. dispar is much more prevalent than E. histolyt... Creepy Dreadful Wonderful Parasites blogs http://www.medworm.com/rss/comments.php?id=2622071 Mon, 13 Jul 2009 10:08:00 +0100 2622071
