“…This would be explained as follows: (i) the spread of TRE in soil depth was faster than that of TRP, and (ii) the survival time of TRE in plough layer is shorter than TRP, especially in cucumber rhizosphere soil. A study found that multi-antibiotic resistant E. coli died off significantly faster than any of other antibiotic-sensitive strains (Duffy et al 2006); once Pseudomonas spp. acquired antibiotic resistance genes, they became highly adapted to environmental stresses (Silby et al 2011).…”

The effects of pig manure application on the spread of tetracycline resistance in bulk and cucumber rhizosphere soils: a greenhouse experiment

Understanding the dynamics of tetracycline-resistant bacteria (TRB) and tetracycline resistance genes (TRGs) in bulk and rhizosphere soils is important to evaluate the spread of TRGs from pig manure to human. In this work, a greenhouse experiment was conducted to investigate the difference in abundance of TRB, tetracycline-resistant E. coli (TRE), tetracycline-resistant Pseudomonas spp. (TRP), as well as TRGs between bulk and cucumber rhizosphere soils. The application of pig manure resulted in the long-term persistence of TRB, TRE, TRP and TRGs in bulk soil and rhizosphere of cucumber for at least 65 days. Pig manure application dose was the major driving force in altering the abundances of TRB and TRE, whereas TRP was disturbed mainly by compartment (bulk soil or rhizosphere). Both TRE and the percentage of TRE in bulk and rhizosphere soil were increased linearly along with the increase in dose of pig manure. The exponential relationships between pig manure dose and TRP along with TRP percentage were also noted. There were significant differences of relative abundances of TRGs between bulk and cucumber rhizosphere soils, suggesting the use of pig manure exerted a more lasting impact on the spread of TRGs in the rhizosphere than in the bulk soil.

“…Duffy et al (2006) reported that MDR E. coli O157:H7 (resistant to 10 antibiotics) when subjected to food stresses (acid and heat) was found to act very differently to the unstressed antibiotic sensitive and antibiotic resistant VTEC strains. All VTEC strains tested were found to survive for approximately 30 days in orange juice at pH 4.4 and 25 days in yoghurt at pH 4.2.…”

Escherichia coli O157:H7 in Raw Meat in Addis Ababa, Ethiopia: Prevalence at an Abattoir and Retailers and Antimicrobial Susceptibility

Background: Although raw meat and its products are commonly consumed in traditional Ethiopian diets, E. coli O157: H7 is rarely studied compared to other countries. Thus the present study has been designed to determine the prevalence and assess the antimicrobial susceptibility of E. coli O157: H7 isolated from beef, sheep meat and goat meat at one abattoir and in 48 selected raw meat retail shops in Addis Ababa.

“…67 In another study that involved a range of food types, Duffy et al 68 compared the survival of susceptible and resistant strains of E. coli in various food matrices. Orange juice and yogurt were inoculated with antibiotic-sensitive (AS) and laboratory-created antibiotic-resistant mutants (MAR) of E. coli O157:H7 or E. coli O26, and their growth/survival was monitored at 37°C or in storage at 4°C.…”

Foodborne antibiotic-resistant pathogenic bacteria such as Campylobacter jejuni, Bacillus cereus, Clostridium perfringens, Escherichia coli, Salmonella enterica, Staphylococcus aureus, Vibrio cholerae, and Vibrio parahemolyticus can adversely affect animal and human health, but a better understanding of the factors involved in their pathogenesis is needed. To help meet this need, this overview surveys and interprets much of our current knowledge of antibiotic (multidrug)-resistant bacteria in the food chain and the implications for microbial food safety and animal and human health. Topics covered include the origin and prevalence of resistant bacteria in the food chain (dairy, meat, poultry, seafood, and herbal products, produce, and eggs), their inactivation by different classes of compounds and plant extracts and by the use of chlorine and physicochemical methods (heat, UV light, pulsed electric fields, and high pressure), the synergistic antimicrobial effects of combinations of natural antimicrobials with medicinal antibiotics, and mechanisms of antimicrobial activities and resistant effects. Possible areas for future research are suggested. Plant-derived and other safe natural antimicrobial compounds have the potential to control the prevalence of both susceptible and resistant pathogens in various environments. The collated information and suggested research will hopefully contribute to a better understanding of approaches that could be used to minimize the presence of resistant pathogens in animal feed and human food, thus reducing adverse effects, improving microbial food safety, and helping to prevent or treat animal and human infections.
