Abstract
Disorders of lymphoid organs are often common in sheep and are not detected
easily until related clinical signs are observed. These are important in understanding
the disease process but are generally neglected during routine post mortem
examination. Thus examination of lymphoid organs at necropsy/slaughter is the only
way to understand pathology behind disorders of lymphoid organs. The present study
was therefore aimed at documenting various pathological conditions affecting the
lymphoid organs of sheep. A total of 110 sheep carcasses were examined, lymph node
lesions were recorded in all cases where splenic lesions in 76 (69.09 %) cases.
Prominent clinical signs observed were related to different systems such as digestive,
respiratory and urogenital. Lymph nodes pertaining to respective systems along with
spleen were examined in all cases. Based on gross and histopathological changes, the
lymph node lesions were classified as congestion in 56 (50.09 %) cases, oedema in 15
(13.63 %) cases, reactive hyperplasia in 27 (24.54 %) cases, lymphoid depletion in
five (4.54 %), liquefaction in seven (6.36 %) cases caseation in five (4.54 %) cases,
chronic lymphadenitis in nine (8.18 %) cases, discrete eosinophilic accumulation in
eight (7.27 %) cases, hemosiderosis in five (4.54 %) cases, necrotic debris
accumulation and anthracosis in four (3.63 %) cases. Likewise splenic lesions were
classified as congestion in 32 (29.09 %) cases, oedema in 20 (18.18 %) cases,
haemorrhages in 11 (10.00 %) cases, hyperplasia in eight (7.27 %) cases,
hemosiderosis in seven (6.36 %) and amyloidosis in four (3.364 %) cases. Thus the
findings of the present study concluded that disorders of lymphoid organs are
important with respect to sheep health and proper attention is needed to mitigate the
losses due to the disorders of lymphoid organs and associated mortality by taking
proper managemental care.
