Nalaz antitela protiv virusnog arteritisa kod kobila u pripustu

Sažetak
Virusni arteritis konja (EAV) predstavlja respiratorno, virusno, kontagiozno oboljenje ekvida, a uzročnik je virus iz roda Arterivirus (EVA). Oboljenje karakterišu lezije u malim krvnim sudovima, posebno arteriolama. Oboljenje najčešće protiče subklinički ili akutno. EAV infekcija može izazvati simptome slične gripu odnosno respiratorne simptome bolesti i to kod odraslih konja, abortus kod gravidnih kobila, intersticijalnu pneumoniju kod mladih ždrebadi, i perzistentnu infekciju kod pastuva. Infekcija je moguća samo kod životinja iz porodice ekvida. Prenosi se horizontalno putem aerosola odnosno respiratorne infekcije prijemčivih konja ili prilikom prirodnog odnosno veštačkog osemenjavanja kobila perzistentno zaraženih pastuva. Od seroloških testova razvijeni su serum neutralizacioni test (SN), indirektna imunofluorescencija, agar gel imunodifuzija i ELISA test, a trenutno su najčešće u upotrebi SN test i ELISA (Timoney, 2002.; OIE 2008.). U radu su korišćeni uzorci krvi od sedam kobila, koje se koriste za pripust. Testom serum neuralizacije utvrđeno je da 5 grla imaju pozitivan nalaz što čini 71,43% pozitivnih životinja u ovom zapatu. Grla koja imaju pozitivan titar antitela su pripuštana više puta, sva grla su imala reproduktivnih problema ali je samo kod jednog grla došlo do abortusa. Grla koja imaju negativan nalaz su bila pripuštena prvi put. Kod njih, iako se drže zajedno sa ostalim grlima, nije došlo do horizontalnog prenosa virusa. Pozitivna grla ispoljavaju određene reproduktivne probleme koji se mogu ali ne moraju pripisati ovom virusu.
