Abstract
A 9 year old sahiwal cow as subitted for postmortem following death in a farm housing
100 animals of various breeds of India. Grossly, the animal showed subcutaneous adipose tissue
gelatinisation and oedema with streaks of haemorrhage in the submaxillary space, pharyngeal
region, neck, dewlap and brisket region. Fibrinous adhesions between the pericardium of heart
and ventral aspect of lungs. Thoracic cavity revealed yellow fluid with fibrin shreds. Pericardial
sac showed thickening with thick dirty white fluid. Samples collected from different organs were
cultured followed by multiplex and species specific Polymerase chain reaction which consistently
showed Mannheimia haemolytica in all the organs. Histopathology showed that the alveolar
spaces were diffusely filled with sero-fibrinous exudates admixed with neutrophils and red blood
cells. interlobular septa were thickened and markedly distended with fibrinous exudation. None
of the other animals housed showed and symptom or mortality. This isolated case of
mannheimiosis could be due to unknown stress which has led to the multiplication of the
organism leading to death of the animal.
