Comparison of Antibiotic Resistance and Virulence Factors among Escherichia coli Isolated from Conventional and Free-Range Poultry
Microbiological contamination in commercial poultry production has caused concerns for human health because of both the presence of pathogenic microorganisms and the increase in antimicrobial resistance in bacterial strains that can cause treatment failure of human infections. The aim of our study was to analyze the profile of antimicrobial resistance and virulence factors of E. coli isolates f...
متن کاملChemical residues in poultry and eggs produced in free- range or organic systems
Residues in poultry arise from accidental or intended exposure to chemicals. The exposure routes are by oral ingestion (feed, water, soil and preening), by inhalation, by dermal absorption or by injection. Chemical contaminants are not a major issue in the principles of organic or free-range systems. Risk management of chemicals has not been addressed widely and if so the attention was focused ...
متن کاملAnalysis of two production inventory systems with buffer, retrials and different production rates
This paper considers the comparison of two ðs; SÞ production inventory systems with retrials of unsatisfied customers. The time for producing and adding each item to the inventory is exponentially distributed with rate b. However, a production rate ab higher than b is used at the beginning of the production. The higher production rate will reduce customers’ loss when inventory level appro...
متن کاملRisks associated with poultry production systems
Every poultry farm has its own risk profile for the introduction of pathogens, subsequent development of disease, and spread of pathogens to other farms. This risk profile is determined by a complex interaction between the levels of infection in an area, the measures implemented on the farm to prevent disease, and other factors including the density of farms in the area and linkages with other ...
