Histopathological Investigations on Renal Lesions in Slaughtered Camel (Camelus dromedarius) in North East of Iran

Abstract

SummaryCamel can tolerates water deprivation conditions more than two months. Kidneys are vital organs in this case. The objective of this study is recognition of kidney lesions. In this study 38 samples of kidney were collected from slaughter house of Tabbas and Mashhad. Specimens were fixed in 10% neutral buffered formalin for at least 24 hours and then routinely processed and then the sections were stained with Haematoxylin and Eosin (H&E), special staining and immunohistochemistry. Histopathological study revealed different lesions and the most common were glomerulonephritis. Other lesions were acute tubular necrosis (ATN), renal cyst and interstitial nephritis. Vascular calcification was significant lesions which were characterized with basophilic material in the intima of vessels. Renal adenoma was diagnosed in one camel and according to review literature it is the first report in camel. Camel is a comparatively hardy animal and is less susceptible to many of the diseases that affect other livestock species in the same area [1] . However, it is apparent that we know too little about the diseases from which it does suffer. In different reports, tubulonephrosis due to DNA virus [2] and Ricketsia-like organisms [3] , glomerulonephritis due to aflatoxicosis [4] , glomerulonephritis and interstitial nephritis [5] were described. Kidney lesions, especially nephritis, are major diseases of domestic animals. Outbreaks occur in camel, cattle, buffaloes and small ruminants in various countries of the world. This study was conducted with the objective of identifying the types of histopathological kidney lesions of slaughtered camels in north east of Iran.Tumours have been rarely documented in captive camelids. In the Arabian dromedary (Camelus dromedarius) there have been reports of an ovarian teratoma [6] ,

“…The choice as an object of histological study of camel kidneys was due to the fact that kidneys are considered an important organ for camels because of their reaction to electrolyte and water balance during dehydration and rapid rehydration of camels due to their residence in desert and semi-desert areas [10][11].…”

Occurrence and pathology of renal lesions in buffaloes

“…In this study the emphasis is on various pathological conditions found in kidney. Certain pathological conditions are common in urinary system of buffaloes such as renal congestion (Saiyari et al, 1996) [25] , infarction (Bamnele et al, 2014) [4] , cystic kidney (Boru et al, 2013) [7] , intertubular haemorrhages (Sankarappa and Rama Rao, 1982) [26] , hyaline degeneration (Mandal et al, 2013) [15] , renal amyloidosis (Mensua et al, 2003) [19] , pyelonephritis (Elias et al, 1993) [9] , glomerulonephritis (Akram, 2001;Rezaie et al, 2014) [1,22] , renal abscess (Kiem and Charan, 1992) [12] , interstitial nephritis (Kiem et al, 1993;Aktar et al, 2015) [13,2] , tuberculosis (Mathur et al, 2000) [18] , etc.…”
