Dear (to) Yuliaxis
For the diagnosis of the transferable gastroenteritis of the pig, you should consider the following thing:
two presentations of the illness, the epizootica and the enzootica exist, the first one is presented for the first time in a swinish farm and it affects to all the productive areas, the clinical signs that you observe are. - sudden diarrhea: profuse, watery, of yellowish green color and fragments of not digested milk, I vomit, death in 24-48 hours in pigs of less than a week of age, agalactea and fever.
in the second presentation it is when it has been controlled later the problem and years it is presented only affecting to sows primerizas or of substitution, it is but difficult to diagnose since you easily with and. coli or rotavirus.
for the I diagnose you should contemplate signs and lesions, for what three pigs affected with diverse stadiums of the illness are included at least (pig without clinical manifestation, pig with I vomit, pig with some days with diarrhea). since you will find different lesions and elijes that it shows and so that it proves.
15 yeyuno-ileon cm is sent in a bag of plastic in refrigeration that has some intact areas of the mucous one and others affected and you request the inmunofluorescencia and viral isolation in cellular cultivation.
10 yeyuno-ileon cm is sent where the presence of gas is observed, transparent (he/she atrophies serious of intestinal hairiness), to tie the ends and to infiltrate formol at the 10 and later you deposit it in a flask with formol at the 10 and he/she is carried out the histopatologia.
serología (elisa) the serum of sows is remitted where its litter was affected, as a rule they allow to spend from 12 to 15 days to detect antibodies in these animals. this test makes the diferenciacion among the swinish breathing coronavirus of that of get, the result is positive or negative.
the other test serologica is the seroneutralizacion, the disadvantage of this test they are. - but face that the elisa, doesn't differ among the crown resp. swinish of that of get, he/she gives I title of antibodies that you don't know if it is for an or another illness.
I wait it even serves you this information.
Greetings.
