Abattoir study of the prevalence of renal lesions in slaughtered cattle
International Journal of Veterinary …, 2010
This study was carried out to determine the prevalence and type of renal lesions in cattle that were slaughtered at the Ghaem (Shahriar) and Ziaran (Ghazvin) abattoirs. A total number of 405 clinically normal cattle were randomly selected and renal samples were taken for histopathological study. The cattle were divided into two groups according to sex, and female groups were divided into two age groups (heifer and cow). Thirty-five (8.6%) out of the studied animals had renal lesions including interstitial nephritis, cysts, glomerolonephritis, acute tubular necrosis (ATN), pyelonephritis, amyloidosis, leukosis hydronephrosis and unilateral renal aplasia. Interstitial nephritis was the most common observed lesion (85.7%). The prevalence of renal lesions in female and male cattle were 8.5% and 9.4%, respectively, which was not a statistically significant difference. The prevalence of renal lesions in cows and heifers were 10% and 2.8%, respectively (p<0.05). It is concluded that age is more important influence factor on renal lesion than sex.
Pathological findings of slaughtered camels' (Camelus dromedaris) kidneys in Najaf-Abad, Iran
Veterinary research forum : an international quarterly journal, 2014
The kidney of camel is known to play a vital role in water conservation through the production of highly concentrated urine that may predispose animal to varieties of renal dysfunction. In camels renal disorders have received lesser attention in comparison with other animals, thus there is shortage of information in this area. The present study was conducted on 100 slaughtered camels (Camelus dromedaris) (200 kidneys) in Najaf-Abad district (Iran) to evaluate the frequency and types of renal disorders. Results demonstrated varieties of gross abnormalities in 14.00% of kidneys that out of them, 9.00% were confirmed by microscopic examination. Renal capsular pigmentation, medullary hyperemia, subcapsular calcification, cortical and medullar discoloration, hemorrhage in renal pelvis, nephrolithiasis and hydatidosis were recorded in 3, 6, 5, 6, 3, 2 and 3 cases, respectively. In addition, capsular melanosis, acute tubular necrosis, chronic interstitial nephritis, caseous necrosis, calci...
Renal Amyloidosis in Cattle: a Case Report in Iran
Journal of Veterinary Medicine, Series B, 2000
Renal amyloidosis is a rare condition in cattle and this report is the first in Iran. A 5-year old Holstein cow was referred because o f profuse diarrhoea, ventral oedema and decreased appetite. Physical cxamination revealed a well audible ping area on the upper half of the right paralumbar fossa. At rectal examination, a large firm and circular shaped kidney was palpated. 1,aboratory examination revealed hypoproteinaemia and severe proteinuria. At necropsy, the kidneys were enlarged, yellow and waxy. Amyloid deposits were found in glomeruli by microscopic examination of the kidneys, and with Congo red staining renal amyloidosis was confirmed.
Histological studies on the kidney of Marwari Sheep (Ovis aries)
Journal of Pharmacognosy and Phytochemistry, 2018
The microscopic studies of kidneys of 6 Marwari sheep showed that the thick fibrous capsule consisted of two layers. The outer layer of dense collagenous fibres with a few elastic fibres. Fibroblast and some smooth muscle cell were also present in outer layer. The inner layer consisted predominantly of reticular fibres with collagenous fibres and had a distinct thick smooth muscle layer. Interstitial tissue contained network reticular fibres which extended from the capsule to the apex of papilla. The juxtaglomerular structure and basement membranes were P.A.S. positive. The papillary duct lined with simple columnar epithelium which become transitional before opening into the papilla.
Bacteriological and Pathological Investigations on Ovine Renal Diseases
2015
The present study was carried out on 450 (male and female) sheep at Tiaret abattoir, (Algeria). Seventy (70) urinary samples were taken directly from bladder by sterile syringe after slaughter for the bacteriological study. Urine samples were incubated for isolation of bacteria on blood agar and MacConkey. Kidney samples were taken for histopathological study in order to determine the prevalence and type of renal lesions. Bacteriological examination of urine revealed that 23 (32.8%) of urine samples show positive resultsin bacterial isolation including13 (56.5%) Escherichia coli, 7(30.4%) Staphylococcus aureus and 3(13.1%) Pseudomonas aeruginosa. Pathological study revealed different lesions and the most common were interstitial nephritis 39(8.6%) and glomerulonephritis 28(6.2%). In conclusion, kidney lesions found in the present study, are down hematogenous origin nephritis while isolated germs are commensal organisms that can be found usually in the lower tract urinary tract.

Multifocal interstitial nephritis in pigs has been associated with several infectious agents. The objective of the present study was to investigate several different potential infectious agents associated with ''white-spotted'' kidneys in pigs suffering from wasting at slaughter (aged 6-8 months). Twenty-nine case kidneys (with a ''white-spotted'' gross appearance) classified into 3 macroscopic lesional grades, and 15 control kidneys (lacking gross lesions), were obtained from a pig abattoir. Laboratory analyses to detect potential associations with the aforementioned pathological condition with Leptospira spp., porcine circovirus type 2 (PCV2), porcine parvovirus (PPV), porcine reproductive and respiratory syndrome virus (PRRSV), and bacteria, were carried out. Microscopically, interstitial nephritis with a lymphofollicular inflammatory pattern (follicular nephritis) was observed in both case and control kidneys, with a higher frequency seen in the former ones. No leptospires were identified, although antibodies to the Pomona and Bratislava serovars were detected. Some pyogenic bacteria were also isolated from both case and control kidneys. PCV2 nucleic acid was only detected in 1 case kidney. PRRSV antigen was not found in any tested sample. Some pigs were tested positive for PPV by serology. Apparently, none of the studied agents were specifically associated as being the potential cause of the renal lesions in the studied wasted pigs. The fact that these chronic lesions may have been the consequence of a previous infection with one of these studied microorganisms, or more, and eventually with other non-tested infectious agents during the growing-finishing period, cannot be ruled out.

Renal diseases in cattle are frequently not recognized due to the subclinical conditions. Some species of Leptospira are the main cause of infectious agents that damage the kidneys and lead to abortion and economic losses in cattle and are also of major concern in the public health. This study was aimed to assess the prevalence of renal lesions of slaughtered cattle in the Shiraz abattoir and to determine the correlation between rejected kidneys and infection with Leptospira using nested PCR-restriction fragment length polymorphism (RFLP) techniques. Out of 1000 inspected animals, 205 (20.5 %) revealed the renal lesions. Chronic nephritis (7.5 %), white-spotted kidney (7.3 %), and petechial hemorrhage (3.5 %) were the most prevalent forms of the lesions. A direct correlation between increasing the age and significant increase in the rate of lesions was also observed (P = 0.03). Using nested PCR-RFLP assay, 40.8 % of the tested kidneys were turned to be infected to the pathogenic species of Leptospira. The risk of infection of the kidneys with white spot to pathogenic species of Leptospira (53.8 %) was more than that of the kidneys with other lesions (25.0 %) (P = 0.014). The odd ratio indicates that the kidneys with white spot lesions are likely to be infected with pathogenic species of Leptospira, five times greater than other lesions. This study showed that renal lesions especially white-spotted kidney, which were considerably associated with Leptospira in slaughtered cattle in Shiraz, were very high. This is important in terms of public health and in particular, increases the risk of transmission of disease to human specially in the high-risk careers including farmers, veterinarians, and abattoir workers.
Interstitial nephritis of slaughtered pigs in the State of Mato Grosso, Brazil
Pesquisa Veterinária Brasileira, 2012
This study evaluated histological lesions in kidney samples from pigs with nephritis in two slaughterhouses in the State of Mato Grosso, Brazil. Four hundred samples were subjected to histology, anti-porcine circovirus type 2 (PCV2) immunohistochemistry (IHC), anti-Leptospira sp. immunofluorescence (IF), and polymerase chain reaction (PCR) for PCV2, porcine parvovirus (PPV), and Torque teno virus type 1 and 2 (TTV1, TTV2) detection. Histological lesions were found in 81% of the samples, and mononuclear interstitial nephritis was the most frequent lesion (77.50%). A follicular pattern was observed in 40.97% of the interstitial nephritis lesions. PCV2, PPV, TTV1, and TTV2 were identified in the kidneys by PCR in 27.25%, 28.50%, 94%, and 87.5% of the samples, respectively. Leptospira sp. was not detected through IF. Infection by PCV2 (PCR) and the presence of histological lesions (P=0.008) and giant cells (P=0.0016) were significantly associated. An association was observed between the...
