Microbiology 1 - Mastigophora
| Question | Answer |
|---|---|
| mastigophora motility | undulating membrane & flagella |
| mastigophora nutrition | permeation |
| mastigophora reproduction | mostly binary fission |
| Pathogenic mastigophores | trypanosoma gambiens, trypanosoma cruzi, giardi intestinalis, leishmania donovani, trichomonas vaginalis |
| trypanosoma gambiens transmitted via | tsetse fly |
| 2 species of Trypanosoma Gambiens | T. Brucei Gambiense & T. Brucei Rhodesiense |
| T. Brucei Gambiense | produces chronic disease, lasts several years b/f CNS involvement, deadly |
| T. Brucei Rhodesiense is | rapidly progressive disease, fatal w/n few months b/f CNS involved |
| Trypanosoma Gambiens Rx: | pentamidine, suramin, melarsoprol |
| Trypanosoma Cruzi causes | Chagas' Disease |
| T. Cruzi transmittted by | reduviid bugs (kissing, assassin bugs) |
| T. Cruzi form | pseudocysts |
| T. Cruzi symptoms | severe anemia, mm. pain, nervous disorders, heart disease=death, can destroy motor cortex, can cross placenta |
| Giardia Intestinalis | most primative DNA of any eukaryote |
| Giardia Intestinalis transmitted by | water supply & cyst present in stool |
| Giardia Intestinalis Sx: | inflammatin of bowel, diarrhea, DEHYDRATION, weight loss, nuturitional deficiencies are common |
| Leishmania Donovani causes | Kala Azar (Black poison) & is blood borne |
| Leishmania Donovani transmitted by | sand fly (phlebotomus) |
| Leishmania Donovani Sx: | high fever, weakness, wasting, liver & spleen enlargement |
| Leishmania Donovani Dx: | blood smears |
| Leishmania Donovani Rx: | antimony compounds |
| Forms of Leishmania Donovani | Leishmania Braziliensis, Leishmania Tropica |
| Leishmania Braziliensis causes | many skin lesions |
| Leishmania Tropica causes | single skin lesion (oriental sore, delhi boil) |
| Trichomonas Vaginalis causes | vaginitis - primarily an STD |
| Trichomonas Vaginalis can be transmitted by | fomites (contaminated non living objects) |
| Trichomonas Vaginalis Sx: | intense intching, copious white discharge |
| Trichomonas Vaginalis Rx: | metroniodazole |
