Parvovirus chirwere chakakomba uye zvinosuruvarisa chakajairika chemudumbu imbwa. Mune mbwanana, inogona kazhinji kuve nemhedzisiro inokatyamadza, iyo inogona kutungamira kurufu rwemhuka mumazuva mashoma. Ichi ndicho chikonzero zvakakosha kuti uve wakangwarira mukati memavhiki ekutanga ehupenyu hwemhuka uye nekwaanobva. Parvovirus ndeimwe yehunoremadza hunhu hwembwa.

Parvovirus chirwere chembwa chinokonzerwa neparvovirus CPV2a kana CPV2b. Kunyangwe ichigona kubata imbwa dzese, chirwere ichi kazhinji hachiuraye muimbwa dzakura asi chinogona kuve nemhedzisiro yakakomba muvana vadiki nekuti chinonyanya kunangana nekuvandudza nhengo. Fomu yakajairika ndeye hemorrhagic gastroenteritis, inowanzo kuve nekubatana nekuderera kwechimiro chemhuka. 

Inotakura parvovirus hutachiona hudiki kwazvo (20 kusvika 25 nm). Hutachiona hwakashama uye hwakanyanya kuomarara, hunoita kuti husabatike zvakanyanya munzvimbo yekunze uko kwaunogona kurarama kwemazuva akati wandei kana kunyangwe mavhiki. Utachiona uhu hunoshingirirawo nekushanduka kwetembiricha, zvinoreva kuti kunatsiridza pa60 ° yezvinhu kunenge kusingashande, uye pa acidic pH, iyo inoitendera kuti irarame paPH yemudumbu kunyanya.

Parvovirus ine yemuromo-fecal kutenderera. Inoburitswa muhuwandu hwakanyanya mumasese emhuka dzine hutachiona, uye dzimwe imbwa dzinotapukirwa nekunanzva kana kunhuwidza nzvimbo yakasviba. Nezvese izvi hunhu, parvovirus chirwere chine hutachiona hwakasimba uye hunogona kunetsa kubvisa.

Zviratidzo zvekutanga zvinoonekwa mushure mekupindirwa kwemazuva matatu kusvika mashanu. Zviratidzo zvakati wandei zvinoratidza parvovirus:

• Kuderera kwemhuka uye kurasikirwa kwechido;
• Kukosha kwekushaya mvura mumuviri;
• Manyoka ane hemorrhagic kana asiri-eropa;
• Kudzora.

Zviratidzo izvi zvinokonzerwa nemabatiro anoita hutachiona. Muimbwa, hutachiona hune hukama hwakasimba nenhengo dzinokura. Nekudaro, muimbwanana isingasviki mwedzi mitanhatu yekuberekwa, ichanyanya kunanga ma "enterocyte", ndokuti maseru ematumbo ayo achakwanisa kupindamo wozotevedzera. Kana yangowanda muhuwandu hwakakwana, zvinokonzeresa necrosis uyezve kuputika kwesero, kuburitsa hutachiona hutsva hwakagadzirwa muura. Iyi lysis yemasero ematumbo ndiyo inotsanangura kuti nei zviratidzo zveparvovirus zviri zvekugaya uye zviratidzo zvekubuda ropa.

Parvovirus zvakare inowanzo kukonzeresa immune system, kusanganisira kuderera kwenhamba yekutenderera masero machena eropa. Mhuka iyi inova nehanya zvakanyanya nehutachiona hwechipiri hwehutachiona.

Kuongororwa kweparvovirus kunogona kuitwa nachiremba wako wemhuka, paanozivisa huwandu hwezviratidzo zviri pamusoro, izvo zvinomutungamira kuchirwere ichi. Dzimwe nguva kuongororwa kunogona kupedzwa uine huwandu hweropa huwandu hunoratidza lymphopenia. Iyo yekupedzisira kuongororwa kunoitwa neye ELISA bvunzo pamasese.

Nehurombo, hapana chaiyo inoshanda kurapa kweutachiona uhu. Chiremba wako wemhuka anozoisa chiratidzo chekurapa kutsigira mhuka nepo immune yayo ichibvisa hutachiona. Mushonga uyu unobatanidza anti-emetic, anti-diarrhea, anti-hemorrhagics nemishonga inorwisa mabhakitiriya kuitira kudzivirira hutachiona hwechipiri. Izvo zvakakosha, mukuwedzera kune uku kurapwa, kupa kwakakosha kudzoreredza kune iyo mhuka diki, nekuti kazhinji ndiko kushomeka kwemvura kunogona kuiuraya. Izvi zvinowanzoitwa nekupomedzerwa kunoda kurapwa kwemhuka.

Kuti ubvise chirwere ichi, zvakakosha kuti ubatanidze hutano hwekuzvidzivirira pamwe neese marapirwo aya. Chokwadi, hutachiona hwechirwere uye kushora kwacho zvinoreva kuti kazhinji kune hutachiona hwakawanda munzvimbo yekunze. Nzvimbo dzekugara dzemhuka dzinofanirwa kucheneswa zvine hungwaru zvobva zvasvinwa nemishonga nebleach. Mhuka dzinorwara dzinofanirwa kuiswa kwavo vega sezvo vachiramba vachidurura hutachiona. Vakuru vanofanirwa kubaiwa jekiseni nekuti anowanzo kuve matura ehutachiona avanogona kudurura zvisingaite. Chekupedzisira, munzvimbo dzinowanikwa mhuka zhinji (kennels, kuberekesa, nezvimwewo), nzvimbo yekukambaira uye kubaiwa nechimbichimbi kazhinji kunodiwa kupwanya hutachiona.

Kurwisa chirwere ichi sevamwe vazhinji, kurapwa kwakanyanya kudzivirira. Parvovirus ndeimwe yekudzivirira kwembwa diki. Kana amai vakabaiwa jekiseni chairo, vanobva vatumira kuchengetedzwa kune mbwanana kuburikidza nema antibodies anotapuriranwa panguva yekubata uye panguva yekuyamwisa. Izvi zvinowanzo kukwana kudzivirira mbwanana kwemavhiki avo masere ekutanga. Panongopera mavhiki masere aya, zvakakosha kuti mwana wako abayiwe jekiseni. Munzvimbo dzine njodzi kana munzvimbo dzinogarwa, kubaiwa kwembwanana kunogona kutarisirwa nekudzokororwa mazuva ese gumi kusvika gumi neshanu kweanosvika mavhiki gumi nemaviri, uko hutachiona hwakareba hunopinda.
