microvilli
Mother of all respiratory problems
PRDC
is a condition wherein multiple pathogens come together at the same time and cause respiratory disease in swine
PRDC
organisms that are able to cause disease on their own;
peimary patjogens
induce subclinical disease, clinical ensues when animal is immunocompromised or in the presence of other primary pathogens;
opportunistic pathogen
in most cases, the pathogens will amplify each others clinical signs, this leads to more severe damage
synergism
in some instances 1 pathogen will prevent reproduction of the other
inhibition
1 pathogen would actually lead to the decline in growth of the other
antagonism
Pathogenic interaction of viral infections
inhibitions
Necropsy: pericardium opaque, cheesy exudate
