YProtozoa vs Helminths
Protozoa thiab helminths yog ob pawg loj ntawm cov kab mob ua haujlwm ua kab mob thiab muaj peev xwm ua rau muaj ntau yam kab mob rau tib neeg. Hauv kev txhais, kab mob parasites yog cov kab mob uas nyob hauv lossis ntawm lwm yam kab mob (hu ua tus tswv), thiab muaj peev xwm ua rau tus tswv tsev puas tsuaj. Qhov kev sib raug zoo lom neeg lossis qhov tshwm sim no hu ua parasitism. Cov kab mob parasitic tseem ceeb no suav nrog cov kab mob multicellular thiab unicellular. Txoj kev kawm ntawm cov kab mob no hu ua parasitology. Feem ntau cov kab mob parasites muaj lub neej voj voog, thiab yog li, lawv xav tau ntau tshaj ib tus tswv tsev kom ua tiav lawv lub neej voj voog. Muaj peb hom hosts muaj, uas yog; reservoir host, intermediate host, thiab tus tswv tsev.
YProtozoa yog dab tsi?
Txhua tus protozoa yog cov kab mob unicellular eukaryotic thiab muaj cov nuclei zoo. Ntxiv nrog rau nuclei, tag nrho cov ntawm lawv muaj lwm cov organelles xws li Golgi complex, mitochondria, ribosomes, thiab lwm yam. Feem ntau ntawm cov protozoa yog dawb-nyob thiab muaj ntau hom vacuoles hauv lawv cov hlwb. Cov kab mob no nyob ua trophozoites lossis cov ntawv cog qoob loo. Txawm li cas los xij, feem ntau ntawm cov protozoa muaj peev xwm ntawm encystation, uas ua rau lawv muaj sia nyob hauv ib puag ncig hnyav. Parasitic protozoans feem ntau muab faib ua peb phyla, (a) Sarcomastiyophora, uas suav nrog cov protozoa uas muaj flagella lossis pesudopodia lossis ob hom locomotor organelles nyob rau txhua theem ntawm lawv lub neej voj voog, (b) Apicomplexa, uas suav nrog cov kab mob uas muaj apical complexes, (c) Ciliophora, uas muaj cov protozoan uas muaj cilia lossis ciliary organelles tsawg kawg ib theem ntawm lawv lub neej voj voog. Qee qhov piv txwv rau protozoa yog Trypanosoma, Giardia, Entamoeba, Babesia, thiab Balantidium. Qee cov kab mob tshwm sim los ntawm protozoa suav nrog malaria, amebiasis, trypanosomiasis, thiab lwm yam.
Herminths yog dab tsi?
Parasitic helminths yog cov kab mob ntau yam, thiab lawv lub cev kwv yees yuav txawv ntawm 1 hli mus rau 10 m. Kev kis kab mob ntawm helminths tuaj yeem yog los ntawm kev noj ncaj qha ntawm lawv cov qe, los yog nkag mus rau ntawm daim tawv nqaij los ntawm lawv cov theem larval, los yog kis ntawm lub neej voj voog mus rau cov tswv ntawm kab vectors. Parasitic helminths tau yoog zoo rau kev ua neej nyob thiab muaj sia nyob hauv lawv tus tswv tsev lub cev. Cov txheej txheem sab nrauv ntawm lub cev ntawm helminths qhia qee qhov kev hloov pauv zoo kawg li txhawm rau tiv thaiv lawv cov kab mob hauv nruab nrog cev los ntawm tus tswv tsev tiv thaiv mechanisms. Clinically tseem ceeb parasitic helminths muab faib ua peb pawg; (a) Nematodes, uas suav nrog cov kab mob sib kis xws li Ascarislumbricoides, Enterobiusvermicularisetc, (b) Cestodes, uas muaj cov kab mob xws li Taeniasaginata, Diphyllobothriumlataetc, thiab (c) Trematodes, uas muaj cov kab mob xws li Clonorchisinensis, Schistosomas, thiab lwm yam.
Qhov txawv ntawm Protozoa thiab Helminths yog dab tsi?
• Protozoa yog unicellular, whereas helminthsare multicellular.
• Protozoa tsuas tuaj yeem pom los ntawm lub tshuab tsom iav xwb, qhov helminths feem ntau pom nrog qhov muag liab qab.
• Protozoa muaj peev xwm sib npaug hauv lawv cov tswv tsev, tab sis feem ntau helminths tsis muaj peev xwm xws li.
• Protozoa muaj lub neej tsis kawg, hos helminths muaj lub neej ntev.
• Lub neej voj voog ntawm helminths muaj theem ntawm cov neeg laus, qe thiab larva, whereas tsis muaj xws li theem ntawm protozoa.
