I truly believe some strains of this bacterium are pathogenic for piglets and can cause diarrhea and reduced growth rate; however, we do not know yet how to identify them!
The main aspect that cannot be forgotten is the complete approach necessary to evaluate all possibilities. In that sense, samples have to be collected and tested to all possible agents that might cause diarrhea.
The ideal sample for diagnostic of neonatal enteric pathogens is the submission of live piglets.
