Indlela yokumisela iPRRS kwiiFama zeehagu

IPorcine Reproductive and Respiratory Syndrome (PRRS) sisifo esisuleleka kakhulu yintsholongwane esichaphazela iihagu, sibangela ilahleko enkulu yezoqoqosho ekufuyweni kweehagu kwihlabathi jikelele. Uzinzo lwePRRS kwifama yeehagu yeyona nto ibalulekileyo ekulawuleni nasekulawuleni isifo. Ukubona ukuba ingaba i-PRRS izinzile na phakathi kwefama kubandakanya indibaniselwano yokubeka iliso kwiimpawu zeklinikhi, uvavanyo lwaselabhoratri, kunye nokuphumeza amanyathelo asebenzayo okhuseleko lwendalo. Eli nqaku lichaza amanyathelo angundoqo okuvavanya i-PRRS kwifama yeehagu.

1.Uqwalaselo lwezonyango

Ukuhlolwa rhoqo kweehagu kwiimpawu zekliniki zePRRS linyathelo lokuqala lokuhlola ukuzinza kwesi sifo. I-PRRS ibonakala ngeendlela ezimbini: ukungaphumeleli kokuzala kwiihagu kunye nesifo sokuphefumula kwiihagu ezikhulayo. Iimpawu ekufuneka zijongwe ziquka:

Imiba yokuzala:Ukwanda kokuqhomfa, ukuzala okufileyo, iintsana ezincancisiweyo, namantshontsho eehagu abuthathaka kwiimazi.

Iingxaki zokuphefumla:Ukukhohlela, ukuphefumla nzima, kunye nokwanda kokubhubha kweehagu ezikhulayo.

Ukunciphisa okanye ukungabikho kwezi zibonakaliso zeklinikhi ekuhambeni kwexesha kunokubonisa imeko ezinzile, kodwa kufuneka ixhaswe yidatha yebhubhoratri.

2.Uvavanyo lweSerological

Uvavanyo lwe-serological lubalulekile ekumiseleni ubukho kunye nokuxhaphaka kwezilwa-buhlungu ze-PRRS phakathi komhlambi. Iimvavanyo eziqhelekileyo ziquka:

I-Enzyme-Linked Immunosorbent Assay (ELISA): Ifumanisa i-antibodies ngokumelene ne-PRRS, ebonisa ukubonakaliswa kwentsholongwane.

Uvavanyo lwe-Immunofluorescence (IFA): Enye indlela yokufumanisa i-PRRS-specific antibodies.

Uvavanyo lwe-serological rhoqo lwamaqela ahlukeneyo eminyaka yobudala lunokunceda ukuchonga iipateni zosulelo kunye nokuzinza okunokwenzeka. Uzinzo luyacetyiswa ukuba amanqanaba e-antibody ahlala engaguquguquki ngaphandle kwe-spikes, ebonisa ukuba akukho usulelo olutsha.

Uvavanyo lwe-3.PCR

Uvavanyo lwe-Polymerase Chain Reaction (PCR) lusetyenziselwa ukubona ubukho be-PRRS yentsholongwane ye-RNA kwiisampulu. Uvavanyo lwe-PCR lunovakalelo oluphezulu kwaye lunokubona usulelo olusebenzayo nokuba lungekho iimpawu zeklinikhi.

Iisampulu zezicubu:Imiphunga, i-lymph nodes, kunye neetoni zivame ukuvavanywa.

Iisampulu zegazi:Ingasetyenziswa ukubona iviremia, ngakumbi kwiihagu ezincinci.

Iziphumo ezingaguquguqukiyo zePCR ekuhambeni kwexesha luphawu olunamandla lozinzo lwePRRS efama.

4.Ukubeka iliso kwiMpilo yamantshontsho eehagu

Impilo yamantshontsho eehagu asandul’ ukuzalwa luphawu olubalulekileyo lozinzo lwePRRS. Iifama ezizinzile zikholisa ukuba namantshontsho eehagu awomeleleyo anamazinga aphantsi okufa. Ukubeka iliso kwiziphene zokuzalwa, imiba yokuphefumla, kunye namandla ngokubanzi kunokubonelela ngolwazi malunga nobukho okanye ukungabikho kwentsholongwane.

5.Imilinganiselo yeBiosecurity

Ukhuseleko lwefama olusebenzayo lubalulekile ekugcineni uzinzo lwePRRS. Oku kuquka:

Iintshukumo zeehagu ezilawulwayo:Ukunciphisa ukungeniswa kweehagu ezintsha ukuthintela ukungeniswa kwentsholongwane.

IiNdlela zoGutyulo: Ukubulala iintsholongwane rhoqo kwiindawo kunye nezixhobo zokunciphisa umngcipheko wokusasazeka kwentsholongwane.

Iinkqubo zokugonya:Ugonyo olungaguquguqukiyo nolucwangcisiweyo lweehagu kunye neehagu lunokunceda ukugcina ukhuselo lomzimba kwaye luthintele uqhambuko.

Ukuphonononga izenzo zokhuseleko lwebhayoloji kwifama kunganceda ukufumanisa ukuba imeko yangoku yePRRS inokuhlala izinzile.

6.Uhlalutyo lweeRekhodi zeMveliso

Ukuphonononga iirekhodi zemveliso yeendlela zokusebenza zokuzala, izinga lokukhula, kunye nokufa kunokubonelela ngobungqina obungathanga ngqo bokuzinza kwe-PRRS. Iimeko ezizinzileyo ze-PRRS zihlala zikhokelela kwiimetrics zemveliso ezingaguqukiyo ngaphandle kokuhla ngequbuliso okanye izikhonkwane.

7.Uthethwano rhoqo ngoNyango lweZilwanyana

Ukubonisana nogqirha wezilwanyana onamava kwi-PRRS kubalulekile ekutolikeni iziphumo zovavanyo kunye noqwalaselo lwezonyango. Banokubonelela ngesikhokelo kuvavanyo olongezelelweyo, izicwangciso zokugonya, kunye nohlengahlengiso kwiiprothokholi ze-biosecurity.

Ukuqukumbela

Ukumisela uzinzo lwe-PRRS kwifama yeehagu kufuna indlela ebanzi ebandakanya uqwalaselo lwezonyango, uvavanyo lwaselabhoratri, uvavanyo lwe-biosecurity, kunye nokubonisana neengcali. Ukuzinza kuboniswa ngokungabikho kosulelo olutsha, iziphumo zovavanyo lwe-serological kunye ne-PCR ezingaguqukiyo, amantshontsho eehagu asempilweni, kunye neemetrics zokuvelisa ezizinzileyo. Ngokuhlala ebeka esweni le miba, amafama angakwazi ukulawula ngcono i-PRRS kwaye anciphise impembelelo yayo kwimisebenzi yabo.
