Pestă porcină africană

Pesta porcină africană, numită și febra porcină africană sau boala lui Montgomery, este o boală virală hemoragică febrilă extrem de contagioasă și foarte severă a porcilor domestici și mistreților, cauzată de un virus ADN dublu catenar din familia asfarviride care se propagă foarte rapid în populația porcină prin contact direct sau indirect. Boala se caracterizează anatomopatologic prin diateză hemoragică generalizată, leziuni degenerative și necrotice în diferite organe, iar clinic în formele acute a bolii prin hipertermie (40,5-42,2°C), leziuni cutanate (eritem, cianoza pielii, în special la urechi, coadă, membrele posterioare și pe abdomen, peteșii, echimoze), tulburări digestive (inapetență, vome, constipație, diaree mucoasă sau sanguinolentă), tulburările respiratorii (dispnee, tahipnee, respirație întreruptă, tuse, eliminare de spumă sanguinolentă din gură), tulburări nervoase (somnolență, apatie, adinamie, mers instabil, crampe, hiperexcitație, crize convulsive, pareze și paralizii, decubit lateral), conjunctivită, secreții nazale seroase, seromucoase sau mucopurulente sau epistaxis, la scroafele gestante unul dintre primele simptome observate este avortul. Mortalitatea este de 90-100% în cazul formelor supraacute și acute a bolii. Pesta porcină africană provoacă pierderi economice mari din cauza depopulării catastrofale a fermelor de porci în zonele afectate prin decesul și sacrificare lor, punerea în aplicare a măsurilor sanitare și impunerea restricțiilor comerciale. Pesta porcină africană este o boală transfrontalieră care se poate răspândi rapid de la o țară la alta și este una dintre cele mai periculoase boli ale porcinelor, fiind inclusă în lista A a Organizației mondiale pentru sănătate animală
