EMIKPE, B. O  y  AKPAVIE, S. O. The Pattern of Distribution of Pneumonic Consolidation in Experimental Peste des petits ruminants Virus (PPRV) and/or Mannheimia Hemolytica Infection in West African Dwarf Goats. Int. J. Morphol. [online]. 2010, vol.28, n.2, pp.563-568. ISSN 0717-9502.

The study into the pattern of distribution of the lung consolidation associated with common viral and bacterial pneumonia and their co-infection in subsaharan goats is scanty in literatures. Fifty apparently healthy West Africa Dwarf goats (WAD) six months of age were used for the experiment. The animals were divided into groups A, B, and C with 15 goats each while 5 goats served as control. Group A goats infected with 1ml of pure culture (1 X 109 CFU) of Mannheimia haemolytica MH A2, while group B with 1ml of pure cultured 106.5 TCID50 PPR virus grown in Baby hamster kidney cell lines and group C with 1 ml of PPRV and a week later 1ml of MH A2. The degree of consolidation or pneumonia as a percentage of the total lung volume was determined by visual observation, palpation and measurement of the lesion which is estimated as a percentage of each lobe. Student t-test were used to test for significant differences. The right lungs have a higher lung consolidation percentage than the left in all the treatment groups. The accessory lobe was affected in the PPRV group. The MH group has the highest lung consolidation percentage (10.1%). The PPRV 1-28dpi has the lowest consolidation percentage (1.06%). There is significant difference in the consolidation percentage and mortality between MH, PPR+MH, PPRV 28-45 dpi and PPRV 1-28dpi (P<0.05). This observation further show that the right lung and the anterior lobes were more affected in experimental viral and bacterial respiratory pathogen and their co-infection as the trachea birfucation is first to the right and the distance between the right and the left birfucation was 1.5±0.35cm. It is the first study that describes and compare the pattern of distribution and morphometry of pneumonia in experimental PPRV, MH and PPRV+MH infections in goats.
