Conclusions:The antimicrobial activities of all the four plant extracts are comparable and their potential as alternatives in the treatment of infections by these microorganisms were present in the poultry litter.Susceptibility testing is conduced on isolates using drugs selected on the basis of their importance to human medicine and use in poultry production.展开更多
