Fig. 2From: Evaluation of the clinical efficacy of a water soluble formulation of tylvalosin in the control of enzootic pneumonia associated with Mycoplasma hyopneumoniae and Pasteurella multocida in pigsPen mean M. hyopneumoniae genomic copies (log transformed) in bronchoalveolar lavage recovered at necropsy in M. hyopneumoniae only challenge study (Mhyop-only) for tylvalosin pigs (TVN group) and untreated pigs (CTL group). Box plots represents the arithmetic mean of each pen. There were 6 pigs in each pen, 17 pens for each treatment. Pigs were challenged endotracheally with lung homogenate containing 1 × 105 ccu of M. hyopneumoniae in 10 ml on Day 0 and Day 1 and samples collected on Day 28.
