Nephropathic strain of IBV

In recent days, we have been getting so many cases pertaining to gout, which is mostly considered as a metabolic disorder. As a routine, we have given treatment for the same and failed as we thought it was just a gout. Later we have been investigated grossly and came to conclusion that it was probably due to IBV. Postmortem findings were 1. Pale and hypertrophied kidneys 2. Tophi of urate Crystals all over organs namely heart, liver, lungs, airsacs, over intestines and even at joints. 3. Swollen bursa at 21st day of age in broiler 4. Watery diarrhoea as a general sign 5. Sitting postures even after death (a classical sign in gout) 6. Tracheal congestion 7. Dehydrated body 8. Uric acid tophi in gallbladder All these cases were diagnosed in and around Guntur, Andhra Pradesh territories where 30 lakhs population of broilers and 30 lakhs of layers were habitated Flocks of 14 to 21 days of age were suffered a lot in our findings and mortalities were about 50 to 60 birds in a flock of 2500. We have been succeeded in treating cases by doing these 1. Isolation 2. Immune boosting 3. Antibiotics with BH combinations 4. Spraying of viricides 5. Last and important is IB plus Lasota in DW Hence it may be an emerging situation to protect the industry here by means of vaccination and maintaining the strict biosecurity. Dear doctors, I may kindly have your highness of attention for deep analysis of this issue and treatment regimen to be followed.
