Unformatted text preview: MT 450 Entamoeba Histolytica (intestinal protoza and amoebae) 1) Major Disease Pathology:- Causes dysentery, gastrointestinal ulcers, with or without lesions in liver, lung or brain- extra intestinal infection - able to invade tissue causing systemic disease 2) Specimen in which the Organism would be Found [stool, bloodm cerebrospinal fluid, sputum, tissue(liver, lung, muscle, brain ,eye..)]- serological - ONLY E Histo. = trop invades the wall of colon, gains access to blood circulatory system, spreads to liver, brain or lung causing absecesses in these tissues 3) Diagnostic Form of the Organism [ova, egg, ameba, trophozoite, cust, flagellate, ciliate, microfilariae, worm, gamete, scolex, proglottid,] and its Distinguishing Characteristics- ingest red blood cells - diarrhea with blood and mucus in stools 4) Infective Form of the Organism 5) Infective stages ( tropozoite, cyst, sporozoite, ova, etc)- ONLY E Histo. = trop invades the wall of colon, gains access to blood circulatory system, spreads to liver, brain or lung causing absecesses in these tissues - Tropozoite: o Finely granular cytoplasm o Evenly distributed peripheral chromatin o Small central karysome o Progressive motility o ingested RBC = E. histoytica - Cyst: o Up to 4 nuclei o Small central karysome o Elongate chromatoid bodies with rounded blunt ends 6) Vector [animal, insect, as appropriate] 7) Whether the organism is Pathogenic, Non-pathogenic, or commensal- pathogenic form 8) Common Disease Names associated with the organism Entamoeba Hartmanni (intestinal amoebae) 1) Major Disease Pathology: 2) Specimen in which the Organism would be Found [stool, bloodm cerebrospinal fluid, sputum, tissue(liver, lung, muscle, brain ,eye..)] 3) Diagnostic Form of the Organism [ova, egg, ameba, trophozoite, cust, flagellate, ciliate, microfilariae, worm, gamete, scolex, proglottid,] and its Distinguishing Characteristics 4) Infective Form of the Organism 5) Infective stages ( tropozoite, cyst, sporozoite, ova, etc) 6) Trop a. Finely granular cytoplasm b. Evenly distributed peripheral chromatin c. Small central karysome d. Non progressive motility 7) Cysts a. Up to 4 nuclei b. Elongated chromatoid body with blunt smooth ends c. Central compact karyosome 8) Vector [animal, insext, as appropriate] 9) Whether the organism is Pathogenic, Non-pathogenic, or commensal 10) Common Disease Names associated with the organism - old name small race histolyica (non-pathogen) Entamoeba Coli (intestinal amoebae) 1) Major Disease Pathology: 2) Specimen in which the Organism would be Found [stool, bloodm cerebrospinal fluid, sputum, tissue(liver, lung, muscle, brain ,eye..)] 3) Diagnostic Form of the Organism [ova, egg, ameba, trophozoite, cust, flagellate, ciliate, microfilariae, worm, gamete, scolex, proglottid,] and its Distinguishing Characteristics 4) Infective Form of the Organism 5) Infective stages ( tropozoite, cyst, sporozoite, ova, etc)- Trop: o Coarsely granular cytoplasm o Unevenly distributed peripheral chromatin...
