ABSTRACT
This work aims to review about coronaviruses in swine, emblazoning there's differences. Transmissible gastroenteritis and epidemic diarrhea are imported diseases, as they generate a high mortality rate in lactating piglets and economic losses. These viruses reach enterocytes, causing villous atrophy;affected animals present watery diarrhea, vomiting, hypoxia and dehydration. Two other viruses have recently emerged, the swine deltacoronavirus and the swine acute diarrhea syndrome virus, which have pathogenicity and clinical signs similar to those described in previous diseases. In the other hand, the porcine respiratory coronavirus and the hemagglutinating encephalomyelitis virus have distinct clinical signs. The first causes mild or subclinical respiratory manifestations and the second neurological signs, vomiting and emaciation, mostly affecting piglets younger than 4 weeks. As there is no specific treatment for these diseases, and vaccines do not provide full protection, a good biosecurity program is the main way to control and prevent them.
