Shahad G. Saeed, Jihad A. Ahmed, Nawres N. Jaber.




Abstract

This study was conducted to verify the presence of macroscopic and microscopic lesions and the accompanying changes
in the blood and bacterial isolation to some factors that causing infection in the kidneys, in sheep with acute and chronic kidney
diseases in Basrah province, during the period from November 2021 to April 2022.The results of the blood test for young and adult
sheep also showed a significant (P≤0.05) decrease for each of the (RBCs), (HB), (PCV), (MCV) and (MCHC), and revealed a
significant(P≤0.05)increase in the (DLCs) and neutrophils and lymphocytes. In addition, the results of sheep serum tests as an
indicator of kidney function also showed a significant (P≤0.05) increase in both the level of urea, creatinine and uric acid
concentration and a significant (P≤0.05)decrease in calcium level in affected animals compared to healthy animals, the
bacteriological study showed the presence of anaerobic bacteria that cause kidney disease in sheep, including: Corynebacterium
sp, Bacteroides sp, Prevotella sp. and Porphyromonas sp, each of them has an effect on histopathological changes in the renal
tissue, The result of the macroscopic examination of the kidney samples taken from the affected sheep, including hemorrhagic
lesions and hypertrophy with focal yellowish-white spots spread in the cortex and medulla. The microscopic appearance of
glomerulonephritis and a large infiltration of inflammatory cells in different places of the renal tissue, especially in the interstitial
region as well as between the renal tubes, in addition, showed the enlargement of the renal glomeruli and congestion of the renal
blood vessels and infiltration of large numbers of inflammatory cells, The histochemical section revealed renal fibrosis as a result
of the deposition of fibers and thickening in the basement membrane of Bowman's capsule.

Key words: Pathological; Hematological; Bacteriological ; Ovine Kidney Diseases ;Basrah .
