In vitro susceptibility of resistant Escherichia coli field isolates to antimicrobial combinations

Avian colibacillosis is an infectious disease of chickens caused by avian pathogenic Escherichia coli (APEC). Respiratory viruses and Mycoplasma infections cause damage to the respiratory system of chickens and predispose them to APEC. The APEC field isolates have begun showing increased antimicrobial resistance, leading to failure of treatment and increasing treatment costs and production losses. The objective of this study was to investigate...
