Izifundo Ngezidakamizwa Zokulwa Nezinambuzane Zezilwane
I-Pendahuluan
Izimuncagazi ziyimbangela enkulu yezinkinga zempilo ezilwaneni, kokubili izilwane ezifuywayo kanye nemfuyo. Ukutheleleka kwezimuncagazi akugcini nje ngokunciphisa ikhwalithi yokuphila kwezilwane kodwa kungathinta nokukhiqiza kwemfuyo, kwandise izindleko zokunakekelwa kwempilo, futhi kwezinye izimo kubeka engcupheni yokudluliselwa kubantu (i-zoonosis). Ngakho-ke, imithi yokulwa nezimuncagazi isibe yingxenye ebalulekile yemikhuba yesimanje yezilwane. Izifundo ngemithi yokulwa nezimuncagazi yezilwane zifaka phakathi ukuqonda izinhlobo zezimuncagazi, izindlela zazo zokusebenza, amaphethini okusetshenziswa afanele, kanye nosongo olukhulayo lokumelana.
Izinhlobo Zezinambuzane Ezilwaneni
Ngokuvamile, izilokazane zezilwane zihlukaniswe ngamaqembu amabili amakhulu: ama-ectoparasites nama-endoparasites. Ama-ectoparasites ahlala ebusweni bomzimba wesilwane, njengezinambuzane, amakhizane, izibungu, nezimpukane. Ama-ectoparasites abangela ukulunywa, izilonda zesikhumba, i-anemia ngenxa yokulahlekelwa igazi, futhi angasebenza njengezimbangela zezifo ezifana ne-babesiosis noma i-ehrlichiosis ezinjeni. Okwamanje, ama-endoparasites ahlala ngaphakathi emzimbeni, njengezilokazane zesisu (ama-nematode, ama-cestode, ama-trematode), ama-protozoa (i-Giardia, i-Coccidia), kanye nezilokazane zenhliziyo (i-Dirofilaria ezinjeni).
Emfuyweni efana nezinkomo, izimbuzi, izimvu, nezinkukhu, ama-endoparasite avame ukuba yimbangela eyinhloko yokwehla kwesisindo kanye nokukhiqizwa, kuyilapho ama-ectoparasites engabangela ukucindezeleka, ukulimala kwesikhumba, futhi anciphise ikhwalithi yemikhiqizo yemfuyo efana nobisi nesikhumba.
Umqondo Wezidakamizwa Ezilwa Nezibungu (Izidakamizwa Ezilwa Nezibungu)
Imithi yokulwa nezimuncagazi yizinto ezisetshenziswa ukubulala, ukuvimbela, noma ukuvimbela ukukhula kwezimuncagazi. Empeleni, imithi yokulwa nezimuncagazi ivame ukuhlukaniswa ngokusekelwe kulokho ekuhlosiwe:
1. Imithi yokubulala amagciwane: yezinambuzane (isib. i-albendazole, ivermectin, i-praziquantel).
2. I-Antiprotozoa: ye-protozoa (isib. i-metronidazole, i-toltrazuril).
3. Ama-Ectoparasiticide: ama-parasite angaphandle (isib. i-fipronil, i-permethrin, i-amitraz, i-selamectin).
Ukukhetha umuthi kuthonywa uhlobo lwezinambuzane, uhlobo lwezilwane, ubudala, isimo somzimba (isb., ukukhulelwa noma ukuncelisa), izinga lokutheleleka, kanye nomlando wokusetshenziswa komuthi ngaphambilini.
Indlela Yokusebenza Kwezidakamizwa Ezilwa Nezibungu
Izifundo ze-pharmacology yokulwa ne-parasitic ziqokomisa indlela izidakamizwa ezisebenza ngayo ezinhlelweni zezinto eziphilayo ze-parasitic. Ezinye izindlela ezivamile zokusebenza zifaka:
1. Kuphazamisa uhlelo lwezinzwa lwe-parasite
Isibonelo, i-ivermectin kanye namanye ama-lactone e-macrocyclic asebenza eziteshini ze-chloride eziqhutshwa yi-glutamate, okubangela ukukhubazeka nokufa kwe-parasite. Le ndlela isebenza kahle ngokumelene nezinhlobo ezahlukene ze-nematode kanye nezinye i-ectoparasites.
2. Kuvimbela ukugaywa kwamandla
I-Albendazole kanye ne-benzimidazoles zivimbela ukwakheka kwama-microtubules ezinambuzane, ngaleyo ndlela ziphazamise ukumuncwa kwe-glucose. I-parasite ekugcineni iyafa ngenxa yokushoda kwamandla.
3. Ukonakalisa i-integument noma ulwelwesi lwe-parasite
I-Praziquantel, evame ukuba nezikelemu eziphathwayo, yandisa ukungena kwe-membrane kuma-ion e-calcium, okubangela ukufinyela kwemisipha kanye nomonakalo ezakhiweni zomzimba zalesi silwanyana.
4. Kuvimbela ukwakheka kwe-DNA noma ukuhlukaniswa kwamaseli e-protozoan
Amanye ama-antiprotozoa asebenza ngokuvimbela izinqubo ze-metabolic ezibalulekile kuma-protozoa, ngaleyo ndlela amise ukuzala.
Ukwazi le ndlela yokusebenza kubalulekile ukukhetha umuthi ofanele nokunciphisa amathuba okumelana nawo.
Ifomu Lomthamo kanye Nendlela Yokuphatha
Imithi yokulwa nezilokazane iyatholakala ngezindlela ezahlukene, eklanyelwe izidingo zohlobo kanye nezimo ezigcinwa ngaphansi kwazo. Ezilwaneni ezifuywayo, imithi ivame ukuza ngesimo samaphilisi ahlafunwayo, ukwelashwa okuqondile (amaconsi asetshenziswa esikhumbeni), ama-shampoo, amakhola alwa nezilokazane, noma imijovo. Ezilwaneni ezifuywayo, amalungiselelo omlomo (ama-drenches), imijovo engaphansi kwesikhumba, ukuthululwa, noma izithasiselo zokudla zivame ukusetshenziswa.
Indlela yokuphatha inquma kakhulu ukusebenza kahle komuthi. Isibonelo, ukuthululwa kwemithi ezinkomeni kusebenza kahle ngokumelene nama-ectoparasites kanye nama-endoparasites athile, kodwa kudinga umthamo oqondile ngokusekelwe esisindweni somzimba. Ezinjeni nasemakatini, ukuthululwa kwemithi kungadinga ukufakwa njalo ngenyanga ukuze kuvinjelwe ukutheleleka kwezimpukane nama-tick.
Ukuphepha, Imiphumela Engemihle, kanye Nokucatshangelwa Kwezinhlobo
Akuyona yonke imithi ephephile kuzo zonke izilwane. Izifundo zobuthi zibonise ukuthi ezinye izithako ezisebenzayo zingaba yingozi ezinhlotsheni ezithile. Isibonelo, i-permethrin iphephile ezinjeni kodwa inobuthi kakhulu emakatini. Ngaphezu kwalokho, ezinye izinhlobo zezinja (njenge-Collies nezihlobo zazo) zine-mutation esakhini se-MDR1 esenza zizwele kakhulu emithanjeni ephezulu ye-ivermectin.
Imiphumela emibi engaba khona ihlanganisa ukuhlanza, isifo sohudo, ukudinwa, ukusabela kwesikhumba endaweni yokusetshenziswa, ngisho nezinkinga zezinzwa uma kunobuthi. Ngakho-ke, imithi yokulwa nezilokazane kufanele isetshenziswe ngokwezincomo zikadokotela wezilwane, ikakhulukazi ezilwaneni ezincane, ezilwaneni ezikhulelwe, noma ezilwaneni ezinezimo ezithile zempilo.
Ukumelana Nezinambuzane: Inselele Enkulu
Esinye sezinto ezibaluleke kakhulu ocwaningweni lwanamuhla lokulwa nezimbungulu ukumelana namagciwane ukumelana namagciwane, isimo lapho izimbungulu zilahlekelwa khona ukuzwela kwazo emithini eyayisebenza kahle ngaphambili. Ukumelana kuvame ukwenzeka ezimpethu zamathumbu emapulazini ngenxa yokusetshenziswa kwezidakamizwa okuphindaphindiwe, imithamo engafanele, noma amasu okuvimbela angaphelele.
Imiphumela yokumelana nemithi inzima kakhulu: ukutheleleka kuba nzima ukulawula, izindleko ziyanda, futhi ingozi yokulahlekelwa umkhiqizo iyanda. Ngakho-ke, abacwaningi bakhuthaza indlela "yokulawula ehlanganisiwe" ehlanganisa ukushintshaniswa kwemithi, umthamo onembile, ukuphathwa kahle kwesibaya, kanye nokuhlolwa njalo kwendle ukuze kuqashwe amazinga okutheleleka.
Uhlelo Lwesu Lokuvimbela Nokulawula
Izifundo ngemithi yokulwa nezimbungulu zigcizelela nokubaluleka kokuvimbela, hhayi nje ukwelashwa. Uhlelo olusebenzayo lokulawula izimbungulu luqukethe izinyathelo eziningana:
1. Ukuxilongwa okunembile ngokuhlolwa kwendle, ukuhlolwa kwegazi, noma ukuhlolwa kwesikhumba.
2. Ukwelashwa okuhleliwe ngokwemijikelezo yokuphila kwezinambuzane kanye nezinga lengozi yemvelo.
3. Ukuphathwa kokuhlanzeka kwamakheji, ukuphathwa komquba, kanye nokulawulwa kwenani labantu abathwala izinambuzane.
4. Ukuqapha njalo ukuqinisekisa ukuthi umuthi usasebenza kahle nokuthi awubi namandla okuwumelana nawo.
Ezilwaneni ezifuywayo, ukuvimbela izinambuzane, imikhaza kanye nezimpethu kuvame ukunconywa, ikakhulukazi ezindaweni ezivame ukuba khona. Emfuyweni, amasu okudlisa ngokuzungeza kanye nokunciphisa ukuminyana kwemfuyo kungasiza ekuqedeni umjikelezo wokuphila kwezimpethu.
Isiqondiso Socwaningo Nokusungula Izinto Ezintsha
Ucwaningo lokulwa nezimbungulu luyaqhubeka nokuthuthuka. Kunezindlela eziningana ezibalulekile, njengokuthuthukiswa kwama-molecule amasha akhetha kakhulu izimbungulu, ubuchwepheshe bokukhishwa kwemithi yesikhathi eside, kanye nemithi yokugomela izimbungulu esathuthukiswa izinhlobo eziningana zezimbungulu zezilwane. Ngaphezu kwalokho, izindlela ezisekelwe ezintweni eziphilayo ezifana nokusetshenziswa kwesikhunta esinama-nematophagous (izilwane ezidla izibungu zezibungu) kanye nama-probiotic athile nazo ziyaqala ukucwaningwa njengokwengeza ekulawulweni kwamakhemikhali.
Okunye okusha ukusetshenziswa kwedatha ye-epidemiological kanye nezinhlelo zokusebenza zedijithali ukunquma isikhathi sokuphathwa kwemithi ngokunembe kakhudlwana, ngaleyo ndlela kwenze ukusetshenziswa kwemithi kube ngcono kakhulu futhi kuncishiswe ingozi yokumelana nayo.
Isiphetho
Ucwaningo lwemithi yokulwa nezilokazane ezilwaneni luyinsimu ebalulekile exhumanisa i-parasitology, i-pharmacology, ukuphathwa kwempilo yezilwane, kanye nempilo yomphakathi. Imithi yokulwa nezilokazane idlala indima ebalulekile ekuthuthukiseni ikhwalithi yokuphila kwezilwane ezifuywayo kanye nokukhiqiza kwemfuyo, kodwa ukusetshenziswa kwayo kumele kufaneleke ukuze kuphephe futhi kusebenze kahle. Usongo lokumelana nezifo lwenza amasu okulawula ahlanganisiwe abe abalulekile, asekelwa ukuxilongwa okunembile kanye nemikhuba emihle yokunakekela. Kusukela manje, ucwaningo ngemithi emisha, ezinye izindlela zemvelo, kanye nobuchwepheshe bokuvimbela obuthuthukisiwe kulindeleke ukuthi buqinise imizamo yokulawula izilokazane eqhubekayo.
