Comparative pathological Studies on Kidneys affections in slaughtered farm animals

Abstract

The aim of this study was to detect the comparative pathological affections in kidneys of cattle and sheep. A total number of 192 kidney samples showing different pathological lesions were collected from El-basatin abattoir in Cairo-Egypt; 69 samples were collected from cattle and 123 samples were collected from sheep, respectively. Microscopically, the highest incidence of occurrence of renal interstitial nephritis was found to be 17.39% in cattle and 28.45% in sheep, followed by glomerulonephritis 21.73% in cattle and 25.20% in sheep; circulatory disturbances were 15.94% in cattle and 16.3% in sheep; suppurative nephritis were 11.59% in cattle and 13.00% in sheep; amyloidosis was 7.24% in cattle while in sheep was 13.20%;. Meanwhile, neoplasms were detected in 3.25% cases collected from sheep. Moreover, parasite, stones, polycystic kidney, hydronephrosis and acute necrotic nephritis were observed in few cases of cattle as 2.89%, 7.24%, 2.89%, 8.69% and 4.34% respectively. Detailed gross and microscopical findings in each lesion were described. Inflammatory conditions in the kidneys were a common finding in both cattle and sheep. However, parasitic infestation is not a common finding in renal lesion.

Hydatidosis in Menoufia's three Abattoirs, Egypt: Epidemiological, Histopathological, Economic, and Molecular Insights in Cattle and Buffaloes

“…The overall prevalence of hydatid cysts among the examined animals was 0.96%, with cattle exhibiting a significantly higher infection rate of 1.05% compared to buffaloes at 0.55%. This disparity highlights the increased vulnerability of cattle to hydatid infections in the study's context, and our results align with previous studies comparing the prevalence of hydatid cysts in Egyptian cattle and buffaloes have reported rates of 1.83% and 2.34% by Hassanin et al (2013), 0.61% and 0.2% by Borai et al (2013), and 0.4% for both species by Barghash et al (2017). The observed prevalence aligns closely with these previous Egyptian reports.…”

Pathological and molecular study of kidneys in apparently healthy cattle and sheep with special reference to Leptospira species in central and northern Jordan

“…El-Mashad et al . [ 10 ] found that 17.4% of cattle kidney samples collected from a Cairo slaughterhouse had IN, compared to 28.5% in sheep. For glomerulonephritis, the prevalence is higher in our study than that in the El-Mashad et al .…”

“…The prevalence rates in the literature vary widely. El-Mashad et al [10] found that 17.4% of cattle kidney samples collected from a Cairo slaughterhouse had IN, compared to 28.5% in sheep. For glomerulonephritis, the prevalence is higher in our study than that in the El-Mashad et al [10] study, at 22% and 26% of the cattle and sheep samples, respectively.…”

“…Renal diseases cause significant economic losses every year due to the high death rate, the condemnation of affected organs and carcasses, loss of body weight, and cost of medication and veterinary services. While some renal diseases are cured, others progress to chronic and end-stage renal disease [ 9 , 10 ]. Renal diseases are not rare in animals but are often undetected until they are at an advanced stage.…”

Establishing Background Pathologic Changes of Valve Replacement Surgery in Sheep

“… 20 Several reports in the literature refer to the common occurrence of renal infarcts in sheep, particularly identified at slaughter, however these studies did not perform further analysis or speculation regarding causes of the renal infarcts beyond the potential of septic emboli from previous bacterial infections. 2 , 7 The lack of a definitive cause of infarcts in sheep is likely a combination of the abundance of underlying causes and difficulty in determining when the infarction occurred. Causes of thrombosis in all species include any factor altering the components of Virchow’s triad (vascular injury, hypercoagulability, and abnormal blood flow), with endothelial damage being cited as the most important factor.…”
