What are the causes and stress factors of swine high fever syndrome?
Causes: Swine high fever syndrome is essentially a swine disease caused by mixed infection with multiple viruses, bacteria and protozoa triggered by immunosuppressive swine diseases. Biological factors: mixed infection with pathogens such as classical swine fever virus, circovirus, porcine reproductive and respiratory syndrome virus, pseudorabies virus, Eperythrozoon, Toxoplasma, Streptococcus, Salmonella paratyphi, Mycoplasma, Actinobacillus pleuropneumoniae, Haemophilus parasuis and Pasteurella. There can be more than 15 kinds of pathogens, among which classical swine fever virus has the highest infection rate and is the most typical; mixed infection with Toxoplasma, Eperythrozoon, porcine reproductive and respiratory syndrome virus, circovirus and classical swine fever virus is common, and there is also mixed infection of classical swine fever virus with piglet paratyphoid bacillus, often dominated by classical swine fever virus, together with one or more than two kinds of viruses, bacteria and protozoa, so the mortality rate is high, the cure rate is low, and it may even wipe out the whole herd.
