Fig. 3From: 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 pigsLog transformed pen mean M. hyopneumoniae colony forming units (cfu) in bronchoalveolar lavage and log transformed pen mean P. multocida cfu in lung tissue recovered at necropsy in Mhyop + Pm dual-challenge study for tylvalosin pigs (TVN group) and untreated pigs (CTL group). Box plots represents the arithmetic mean of each pen. There were 4 pigs in each pen, 11 pens for each treatment. Pigs were challenged on Day 0, Day 1 and Day 3 with broth media containing 1 × 109 cfu of M. hyopneumoniae in 5 ml of Mhyop and on Day 14 with broth media containing 1 × 1010 cfu in 10 ml of P. multocida. Both challenges through intranasal route and scored on Day 28. P values from least square means derived from statistical modelsBack to article page
