Satellite imagery of the Urmia region illustrates that the trend of faults are in two main NE-SW and NW-SE directions. Th...

The aim of this study was to isolate, identify and determine the antimicrobial susceptibility of (CP) isolates from acute necrotic enteritis of broiler chickens. All carcasses diagnosed as necrotic enteritis (NE) were sampled, subjected to microbial tests and 40 isolates were identified according to standard procedures. The antimicrobial susceptibility of CP isolates to 20 antibacterial agents ...
