Hi Kimleang, It is very easy to recognize the bacterial infection or viral infection. You must recognize the rate of mortility and the rate of feed intake, if it increases or decreases then make your P.M lesion to recognize if it is bacterial or viral infection. Then go ahead to further serological investigation. These signs don´t mean that there is a virus but it is an indicator to good investigation to the farm and take care from using of antibiotic or injection or vaccination. If you make P.M lesion and see that there is virus infection go away from using of antibiotic or injection or a routine programme of vaccination untill the virus takes its severity and mortility decreases the using antibiotic to overcome secondary bacterial infection but if they are only signs of bacterial infection only use antibiotic as easy as you can. Good luck Dr. Abdelaziz

In some cases if we wait for viral infection to subside before initiating antibiotic therapy . In the meantime secondary bacterial becomes uncontrollable. And some times this flared secondary bacterial infection doesn’t respond to any treatment.
