Demodicosis mumbwa

Demodex mite - iyo inogara yakajairika yeganda mumbwa uye inogona kuwanikwa muganda uye nzeve dzenzeve kunyangwe mumhuka dzine hutano. Inowanikwa paganda revana vachangoberekwa kubva kuna amai mumazuva ekutanga 2-3 ehupenyu. Hazvibviri kutapukirwa nedemodicosis kubva kune imbwa inorwara; intrauterine transmission hainawo kubatanidzwa. Muchidzidzo chematishu embwa dzakafa nekuda kwezvirwere zvakasiyana, zvipembenene izvi zvakawanikwawo munhengo dzemukati, muweti, tsvina nemuropa. Asi zvakawanikwa zvakadaro zvinoonekwa setsaona, sezvo chikwekwe chinofema okisijeni uye, maererano naizvozvo, haigone kurarama mukati memuviri. Kudonha kwezvikwekwe munhengo dzemukati kunoitika neropa uye lymph kubva pakatarisana nekuzvimba. Kunze kwemuviri, zvipembenene izvi hazvigoniwo kurarama.

Inenge 80% yezviitiko zve demodicosis inoonekwa muimbwa dzakachena, 20% chete inoitika mumhuka dzakasununguka. Kune zvakare mhando yekufungidzira: semuenzaniso, Scottish Terrier, Shar Pei, Afghan Hound, Great Dane, English Bulldog, West Highland White Terrier, Doberman vanorwara kakawanda kupfuura vamwe.

Mufananidzo we demodicosis mumbwa

Zvinokonzera

Chikonzero chikuru chekukura kwedemodicosis mumbwa - Inoderedza kusadzivirirwa. Kudzivirirwa kunogona kuderedzwa kunopesana nemashure ezvirwere zvakasiyana-siyana zviripo mumhuka: kutapukira, kuputika, chirwere cheshuga mellitus, zvirwere zvinouraya, zvirwere zve endocrine, uyewo panguva yeestrus uye pamuviri mumakumbo. Kushandiswa kwemishonga yakasiyana-siyana ine immunosuppressive effect (somuenzaniso, mishonga kubva muboka reglucocorticosteroids) inotungamirirawo kuderera kwekudzivirira. Mamiriro asina kunaka ekuchengeta imbwa, kudya kwakashata, kushaikwa kwekurovedza muviri, kuzara, kushaikwa kwemakamuri anodziya ekuchengetedza mumwaka unotonhora. - izvi zvese zvinokonzeresa kuderera kwemasimba ekudzivirira emuviri uye zvinogona kuita chinhu mukukura kwedemodicosis. Chimwe chikonzero che demodicosis - chikanganiso chemavara okugara nhaka, ndiko kuti, kugarwa nhaka. Ichi chikanganiso chinokanganisa lymphocytes (masero ekudzivirira muviri), izvo zvinotungamirira kukuberekwa kusingadzorwi kwezvipembenene.

Zviratidzo zve demodicosis mumbwa

Chiratidzo chekutanga chekufungidzira kukura kwechirwere mumbwa yako - ichi ndicho chitarisiko che alopecia, ndiko kuti, nzvimbo dzemuviri dzine kurasikirwa kwebvudzi uye kukanganisa kwekukura kwezvitsva. Zvimwe zviratidzo zvedemodicosis mumbwa zvinogona kuva tsvuku uye kuputika kweganda, kuumbwa kwepustules. Kunyanya kukoshesa kunofanira kubhadharwa kune ganda rakapoteredza maziso, miromo. Muchikamu chekutanga chedemodicosis, imbwa haigoni kuchenesa, uye zvipembenene izvi hazvizokonzeri kunetseka kumhuka. Kukwenya kunoonekwa chete kana chirwere chechipiri chebhakitiriya kana fungal chakabatanidzwa kune maronda aripo. Mabhakitiriya eStaphylococcus (kunyanya Staphylococcus pseudintermedius) anogona kuwanikwa kazhinji, streptococci, mabhakitiriya akaita setsvimbo uye mbiriso fungi (genus Malassezia) yakati wandei. Muzviitiko zvakanyanya kuregeredzwa, pangave nekuora mwoyo kwekugara zvakanaka, kuramba kudya, mhuka inogona kutofa ne sepsis.

Mhando dze demodicosis

Maererano nekuwanda kwemaronda, munhu anogona kusiyanisa pakati penzvimbo (nhamba shoma yezvipembenene pamuviri) uye generalized demodicosis (kutora nzvimbo huru dzeganda). Nezera, yakakamurwa kuva pwere (demodicosis muvana) uye imbwa dzakura. Nerudzi rwekuratidzwa kwekiriniki - pustular (pyodemodecosis), papular (nodular), squamous (scaly) uye yakasanganiswa.

Inowanikwa munzvimbo

Kazhinji kazhinji inogona kuwanikwa muimbwa diki (kusvika anenge 1 gore). Zvinoenderana nedata yemazuva ano, demodicosis inoonekwa seyakagadzika kana paine maronda mashanu kana mashoma pamuviri ane dhayamita inosvika 2,5 centimita. Aya maronda inzvimbo dzakaganhurwa zvakanaka, dzisina vhudzi, dzine kana dzisina tsvuku, uye kusvuura kunogoneka zvakare. Ganda rinogona kunge riine bluish-grey tint, comedones (madotsi madema) uye kunhuhwirira kusingafadzi dzimwe nguva kunocherechedzwa. Kazhinji kazhinji, maronda akadaro anowanikwa pamuromo, musoro, mutsipa, makumbo epamberi. Iwe unogona kuwana chimiro che "demodectic" magirazi muchimiro chekutsvuka kwakatenderedza maziso. Ingangoita gumi kubva muzana yemakesi ekosi yenzvimbo inoshanduka kuita fomu yakajairika.

Generalized

Mufananidzo wekiriniki wakafanana nedemodicosis yenzvimbo, asi inotora nzvimbo dzakawanda dzeganda rembwa. Itsika kudaidza generalized demodicosis kana paine maronda anopfuura mashanu, kana maronda aya anopfuura 5 centimita, kana kana chikamu chimwe chemuviri chikabatwa sese (muzzle wese, gumbo rese, nezvimwewo). . Clinical zviratidzo zvinosanganisira mhanza, peeling, comedones, kusviba kweganda. Zvingangodaro, kuwedzerwa kwechipiri chebhakitiriya kana fungal flora, iyo inokonzera kuonekwa kwepundu uye pustules, mamota (kuzvimba munzvimbo yemudzi webvudzi, kureva, nechekare muzvikamu zvakadzika zveganda) uye fistulas. Nekusiyana uku kwekosi, itching ichave chikamu chakakosha chechirwere, uye nekufamba kwenguva ichave ikava kunzwa kunorwadza zvechokwadi. Muzviitiko zvakanyanyisa, munhu anofanira kutarisira kuwedzera kwema lymph nodes, kuderera kwechido, uye kuora mwoyo kwemamiriro ezvinhu. Pasina kurapwa, mhuka inofa nokukurumidza.

Generalized demodicosis inosanganisirawo kukanganisa mite kumakumbo embwa. - pododemodecosis. Iwe unogona kuona kuzvimba kwemakumbo, kusviba kweganda, interdigital cysts, fistulous ndima nekubuda kwemhando yakasiyana kubva kwavari, kuremara nekuda kwemarwadzo. Imbwa inogara ichinanzva makumbo nemaoko, kunyanya mapedhi nepakati pezvigunwe. Vanogona kuita hasha pavanenge vachiedza kugeza makumbo avo mushure mekufamba. Podomodedecosis yakaoma kurapa.

Muzviitiko zvisingawanzoitiki, kunyange nzeve dzenzeve dzinobatwa, zvichiita kuti otitis externa (otodemodicosis). Rudzi urwu rwekukuvadzwa kunoreva zvakare kune fomu yakajairika. Iwe unogona kuona kutsvuka kwemukati wemunzeve, kubuda kwebrown, kunhuhwirira kusingafadzi kubva munzeve. Panguva imwecheteyo, imbwa inogona kuzunungusa musoro wayo, kusveta nzeve dzayo kune zvinhu zvakasiyana-siyana, uyewo kukwenya nzeve uye nzvimbo iri pedyo nenzeve (matama, mutsipa).

Wechidiki

Juvenile demodicosis chirwere chevana vaduku vane makore akawanda kubva pamwedzi mitanhatu kusvika ku6. Mhando iyi yedemodicosis inenge nguva dzose inokonzerwa nekuremara kwenhaka mukudzivirira muviri, kureva kuti, mumwe wevabereki airwarawo. Upenyu hwemaputi aya haakwanisi kuzvimiririra kudzora nhamba yezvikwekwe, semugumisiro wekuti huwandu hwavo hunowedzera uye hunokonzera kuratidzwa kwechirwere chechirwere. Mhuka dzakadai dzinofanirwa kubviswa pakuberekana kudzivirira kupararira kwechirwere ichi. Zvimwe zviratidzo zvekiriniki zvichaenderana nechimiro chechirwere chechirwere (chinzvimbo kana chakazara).

mhuka dzakura

Mumhuka dzakura, kukura kwechirwere kunowanzobatanidzwa nekuderera kwekudzivirira kurwisana nemashure echirwere chinokonzera. Naizvozvo, kana demodicosis ichionekwa muimbwa dzakura, kuongororwa kwehutano hwese kunodiwa zvakare: kuongororwa kwemuviri kwakakwana uye zvimwe zvidzidzo. Kunyanya kukoshesa kunofanira kubhadharwa pakutsvaga kwezvirwere zvakadai sechirwere cheshuga mellitus, hypothyroidism, hyperadrenocorticism, uye maronda akaipa. Maererano nedheta, kubudirira kurapwa kwechirwere chepasi kunopa kuregererwa kwakanaka kune demodicosis. Zvisinei, inopfuura hafu yembwa dzakaongororwa zvakakwana dzakaratidza kuti hapana zvimwe zvirwere. Chimwe chinokonzera demodicosis mumhuka dzevanhu vakuru ndiko kushandiswa kwenguva refu kwemishonga inosuppressive iyo yakarongerwa kurapa chirwere chekutanga.

pustular

Iyi fomu inoratidzirwa nekuonekwa kwepustules paganda. Aya mapustules anoputika mushure mechinguva, zviri mukati mawo zvinobuda uye zvooma. Ganda rinogona kutsvuka kana kusviba, rinoita kuunyana uye rakasimba, uye kunhuhwirira kusingafadzi kunoonekwa. Utachiona hweganda hunoitika nekukurumidza zvakakwana uye hunopararira kune dzimwe nhengo dzemuviri dzisina kukanganiswa neparasite.

Papular

Iine fomu iyi, yakatenderedzwa, kazhinji matsvuku uye akaganhurirwa mavhuvhuvhu anogona kucherechedzwa munzvimbo dzakasiyana dzemuviri, dhayamita yavo inogona kusvika 1-6 millimita. Aya mapundu anogona kunge achikwenya mumbwa, asi anogonawo kusakonzera kunetseka zvachose.

Squamous

Nemhando ye squamous, zviduku, zvipembenene zvemasaic zvinoonekwa paganda rembwa, rakafukidzwa nemashizha akafanana nebran. Nokufamba kwenguva, vanotanga kubatanidzwa, munzvimbo idzi kune kuwedzera kwebvudzi.

Mixed

Rudzi urwu rwemaronda runosanganisira ese ari pamusoro pemakiriniki zviratidzo (papules, pustules uye zviyero) uye anogona kunge akanyanya kuomarara, anoodza moyo wemhuka.

Diagnostics

Kuongororwa kunoitwa zvizere, tichifunga nezvenhoroondo (zvichemo zvinoenderana nemuridzi, nhoroondo yekurapa), kuongororwa kwemuviri, uye bvunzo dzemu laboratori. Nzira huru yekusimbisa kuongororwa ndeye microscopy yeganda scrapings. Kukwesha kunodiwa kubva munzvimbo dzese dzakakanganisika dzemuviri. Kuchera kunofanira kunge kwakadzika zvakakwana, kunoitwa nescalpel kusvikira madonhwe ekutanga eropa aonekwa, sezvo chikwekwe chinogara muzvikamu zvakadzika zveganda (bvudzi follicle). Trichoscopy (kuongororwa kwebvudzi rakadzurwa) kana bvunzo yekunamira (kutora zvinhu zvekuongororwa uchishandisa tepi nhete yetepi yekunamira) inogona zvakare kubatsira. Kana pane pustules yakazara pamuviri, zvakakosha kuitisa microscopy yezviri mukati mavo. Kuti uite chirwere chekuongorora, unoda kuwana nhamba yakawanda yezvikwekwe pamatanho akasiyana ekukura kwavo. Kuwanikwa kwechikwekwe chimwe chete kunogona kuve kuwanikwa netsaona, asi zvakadaro hazvifanirwe kuregererwa zvachose. Mumamiriro ezvinhu akadaro, scrapings inokurudzirwa kudzokororwa mushure mechinguva (2-3 mavhiki) kujekesa kuongororwa. Kana otodemodecosis ichifungidzirwa, ipapo microscopy yezviri mukati mekunze kwekunzwa migero inoitwa. Muzviitiko zvakanyanya kupokana, biopsy yeganda ine histological ongororo inogona kukurudzirwa. Uyewo, mumamiriro ezvinhu asina chokwadi, kurapwa kwekuedza kunogona kupiwa nachiremba, kunyange kana kuongororwa kwaisagona kusimbiswa pakugadzwa kwekutanga.

Kurapa demodicosis mumbwa

Mune zvirongwa zvemazuva ano zvekurapa demodicosis mumbwa, iyo yakachengeteka mishonga yemuromo kubva kuboka re isoxazoline (fluralaner, afoxolaner, sarolaner) inoshandiswa. Mishonga yakadaro inoshandiswawo kudzivirira kurumwa nenhata uye zvikwekwe nguva dzose, pasina njodzi yekukuvadza muviri kana ichishandiswa zvinoenderana nemirairo. Chirongwa chekurapa navo chinogona kunge chakasiyana uye zvinoenderana nehuwandu hwekukuvadza imbwa ine demodicosis uye chaiyo mushonga wakasarudzwa.

Mukushaikwa kwemari kana mimwe mikana yekushandisa mishonga yakadai, chirongwa chekurapa chekare uchishandisa mishonga yeboka reavermectin inogona kuiswa. Majekiseni aya anoshanda zvakanaka kana akatorwa nemuromo, asi ane zvimwe zvinokonzeresa (kudonhedza mate, kupera simba, kugwinha-gwinha, kugwinha, nekoma). Kushandiswa kwavo kunopesana muvana vari pasi pemwedzi mitatu yezera. Kune zvakare kusashivirira kwerudzi kune zvinodhaka kubva muboka iri mune dzimwe imbwa (collie, English shepherd dog, Australian shepherd, Scottish shepherd dog nemichinjikwa yavo). Izvi zvinokonzerwa nekuvapo kwejini rakaremara mumuviri wavo, nekuda kwekuti iyo molecule yemishonga "inoramba" muuropi uye haigoni kuisiya, zvichiita kuti matambudziko akawanda etsinga.

Kurapa kwedemodicosis, zvinodhaka kubva kuboka reamitraz muchimiro chemushonga wemvura unogona kushandiswa semabhati pamusoro pechiso chese chemuviri, asi kushandiswa kwayo kunobatanidzawo nemigumisiro inogona kuitika (kuneta, itching, urticaria, kurutsa, kuramba kudya, kufamba kusina kugadzikana kunowanzoitika mushure memaawa 12 -24).

Panewo uchapupu hwekushanda kwepamusoro kwe macrocyclic lactones mukurapa demodicosis, asi nyaya iyi ichiri kukakavara. Muhupo hwehutachiona hwechipiri, gadziriro dzemunharaunda (yakasiyana-siyana antibacterial mafuta uye shampoos) inogona kurongerwa, mumatambudziko makuru, maitiro emishonga inorwisa mabhakitiriya inorayirwa mune dermatological doses.

Izvo zvinodikanwa kuenderera mberi nekurapa demodicosis mumbwa kusvika maviri akateedzana asina kunaka scrapings anowanikwa nepakati pemwedzi mumwe pakati pavo. Kurapa kunogona kuwedzerwa kwemumwe mwedzi mushure mazvo senzira yekudzivirira kudzoka zvakare. Kudzokerazve muchimiro chakajairwa chekosi hakusi kushoma. Kurapa kwavo kunogona kureba, kusvika kumwedzi mitanhatu kana kupfuura. Mhuka dzakadaro dzinogona kutodzingwa.

Ngozi kuvanhu

Demodex chipembenene chakanyatsojeka, kureva kuti, mhuka inoparadza imbwa, asi haigoni kupararisa pavanhu. Uye, sezvakataurwa pamusoro apa, demodex inogara mugari weganda remhuka. Iyo inowedzera, ichikonzera chirwere, chete mumamiriro ezvinhu echimwe chipenyu (nekuda kwekuderera kwekudzivirira kana genetic defect) uye, maererano naizvozvo, haiparadzi.

dziviriro

Kudzivirira kwakanakisisa kwekuitika kwedemodicosis ndiko kuchengetedza kudzivirirwa kwembwa kune yakakwirira. Izvi zvinogona kuwanikwa nekugadzira mamiriro ekugara akasununguka kwaari: chikafu chemhando yepamusoro, kurovedza muviri nguva dzose, kutarisirwa uye rudo. Izvo zvinodiwawo kuita bvunzo dzekudzivirira nguva dzose kune veterinarian kuti uone zvinogona kuitika pathologies, kunyanya kune mhuka dzakura kupfuura makore manomwe. Mhuka dzose dzine chimiro chechimiro chedemodicosis haifaniri kuberekerwa, sezvo nehupamhi hwepamusoro, iyo isina kukwana "demodectic" gene ichapfuudzwa kuvana. Imbwa dzakadaro dzinogona kuchekwa, izvo zvinodzivirirawo kuitika kwechirwere mumakumbo panguva yeestrus.

Zvinogona kuitika

Zvinetso nemaitiro emunharaunda yekosi yedemodicosis uye kurapwa panguva yakakodzera, sekutonga, hazvionekwi. Matambudziko makuru anogoneka anosanganisira hutachiona hwechipiri nemabhakitiriya uye fungal agents. Nekurapwa kusingatarisirwi, pachavawo nekuwedzera kwemalymph nodes anonzwika, kuwedzera kwekushisa kwemuviri, kushushikana kukuru, kuramba kudya, kubatwa kusingatsungiriki. Izvi zvinotevera sepsis uye kufa kwemhuka.

Chinyorwa hachisi kudana kuita!

Kuti uwane ruzivo rwakadzama rwedambudziko, tinokurudzira kubata nyanzvi.
