“…Furthermore, foals that received HIP had significantly lower weekly and cumulative ultrasonographic scores and abnormal ultrasonographic scores were present for a shorter period of time in HIP foals, indicating a less severe form of pneumonia.

Moreover, an increase in platelets, also a non-specific response to bacterial infection (Tafazzoli and others 2006), was only seen in control foals.…”
