“…Opriessnig and Langohr (25) emphasised that interstitial nephritis during PCV2 infection is mainly a sign of chronicity, which appears approximately 35 days after infection and may disappear in the later phase of the infection. Moreover, other viral infections should also be considered like adenovirus type 4, PPV and Torque Teno virus (10,11,24). Though the present study investigated only the occurrence of PCV2 there was no correlation between histopathology of renal lesions and presence of PCV2 DNA by ISH or PCV2 antigen by IHC.…”

“…Renal lesion occur either as primary conditions like cystic kidneys, nephritis, parasitic conditions and neoplasms 6,11,12 or in association with other systemic infections like swine fever, porcine circoviral infections, leptorspirosis etc. [13][14][15][16] . In this backdrop, the present study was conducted to investigate the general occurrence of various spontaneous kidney lesions in slaughtered pigs and to understand their pathomorphology in detail.…”

The present study was conducted to know the occurrence of various spontaneous kidney lesions in slaughtered pigs and to describe their pathomorphological features. A total of 320 slaughtered pigs of either sex and mostly of marketable age were screened for the possible gross renal lesions in diff erent regions of Krishna District in Andhra Pradesh state. Gross and microscopic examination revealed renal lesions of pathological signifi cance in 115 animals (35.94%). Histopathologically, the lesions were categorised as vascular changes (15.65%), nephrosis (7.83%), nephritis (67.83%) and renal cysts (8.69%). Vascular changes were comprised of renal congestion (12.17%) and renal hemorrhage (3.48%). Nephritis was categorized into glomerular (30.44%), interstitial (36.52%) and tubulo-interstitial (0.87%) types. Glomerulonephritis was comprised of acute (3.48%), sub-acute (24.35%) and chronic (2.61%) types; while interstitial nephritis included sub-acute (33.04%) and chronic (3.48%) types. The present study infers a signifi cant occurrence of spontaneous renal lesions in slaughtered pigs; the most common pathological condition being interstitial nephritis and the most consistent lesion being mononuclear cellular infi ltration.

“…In addition to bacteria, many emergent viral diseases have tropism for renal tissue (Drolet et al 2002, Imai et al 2006, Martinez et al 2006, including porcine reproductive and respiratory syndrome virus (PRRSV), porcine circovirus type 2 (PCV-2), porcine parvovirus (PPV), and porcine adenovirus (Nietfeld and Leslie-Steen 1993, Cooper et al 1997, Krakowka et al 2000, Drolet et al 2002, Segales et al 2005, Zimmerman et al 2006, Sarli et al 2008. Renal lesions in pigs inoculated with PRRS virus were characterized by moderate to marked interstitial nephritis, and mild to severe vascular changes (Cooper et al 1997).…”

Actinobacillus suis and Actinobacillus equuli, emergent pathogens of septic embolic nephritis, a new challenge for the swine industryActinobacillus suis y Actinobacillus equuli, patógenos emergentes de nefritis embólica séptica, un nuevo desafío para la industria porcina RESUMENLas lesiones renales son una causa importante de decomiso en los mataderos. Además de las posibles consecuencias en salud pública, el decomiso de órganos tiene un gran impacto económico en la industria de alimento animal. Recientemente, nefritis embólica séptica con lesiones semejantes a infecciones con Actinobacillus equuli en potrillos ha sido detectada en reproductoras y cerdos con peso de mercado. Actinobacillus equuli es fenotípica y genéticamente similar a Actinobacillus suis. Ambas son bacterias Gram-negativas difíciles de diagnosticar en exámenes de rutina. A. suis es un patógeno oportunista capaz de producir septicemia en cerdos, neumonía, poliartritis, nefritis embólica séptica, aborto y fetos momificados. Brotes de la enfermedad clínica parecieran ocurrir con más frecuencia en planteles de cerdos con estrictas medidas de bioseguridad. En cerdos adultos, las lesiones de piel pueden confundirse con erisipela porcina. A. suis y A. equuli son patógenos oportunistas emergentes en la industria porcina y ambos tienen potenciales consecuencias en salud pública, principalmente en aquellas personas que manipulan productos cárneos. El objetivo de esta publicación es presentar una revisión bibliográfica sobre el rol de A. suis y A. equuli en la patogénesis de nefritis en cerdos.
