TLDR
The importance and origin of antimicrobial-resistant Salmonella infections were examined in 52 outbreaks investigated by the Centers for Disease Control between 1971 and 1983, and food animals were the source of 11 of 16 resistant and 6 of 13 sensitive outbreak strains.Abstract:
The importance and origin of antimicrobial-resistant Salmonella infections were examined in 52 outbreaks investigated by the Centers for Disease Control between 1971 and 1983. The case fatality rate was higher for patients infected with antimicrobial-resistant Salmonella (4.2 percent) than for those with antimicrobial-sensitive infections (0.2 percent). In the 38 outbreaks with identified sources, food animals were the source of 11 (69 percent) of 16 resistant and 6 (46 percent) of 13 sensitive outbreak strains.read more

Tetracycline Antibiotics: Mode of Action, Applications, Molecular Biology, and Epidemiology of Bacterial Resistance
Ian Chopra,Marilyn C. Roberts +1 more
TL;DR: Changing the use of tetracyclines in human and animal health as well as in food production is needed if this class of broad-spectrum antimicrobials through the present century is to continue to be used.

Food Animals and Antimicrobials: Impacts on Human Health
Bonnie Marshall,Stuart B. Levy +1 more
TL;DR: The substantial and expanding volume of evidence reporting animal-to-human spread of resistant bacteria, including that arising from use of NTAs, supports eliminating NTA use in order to reduce the growing environmental load of resistance genes.
Journal ArticleDOI
Epidemiology of Drug Resistance: Implications for a Post—Antimicrobial Era
TL;DR: Prevention and control of certain infections that are essentially untreatable have begun to occur as epidemics both in the developing world and in institutional settings in the United States.

TL;DR: The application of the 'precautionary principle' is a non-scientific approach that assumes that risk assessments will be carried out, and anti-Gram-positive growth promoters would be expected to have little effect on most Gram-negative organisms.

Agriculture and food animals as a source of antimicrobial-resistant bacteria.
TL;DR: An effort is made to highlight the various factors that contribute to the emergence of antibiotic resistance in farm animals and to provide some insights into possible solutions to this major health issue.

TL;DR: The results illustrate the spread of antibiotic-resistant organisms fromChicken to chicken and from chicken to man as well as the impact of antibiotics on flora of farm animals and human personnel.

TL;DR: It is suggested that resistance plasmids may be extensively shared between animal and human bacteria, and that spread of multiresistant strains of salmonella among animals and human beings, as observed in Britain, may have been undetected in the United States for lack of comparable surveillance.

Comparison of plasmid profile analysis, phage typing, and antimicrobial susceptibility testing in characterizing Salmonella typhimurium isolates from outbreaks.
TL;DR: Plasmid analysis appeared to be at least as specific as phage typing in identifying epidemiologically related isolates of S. typhimurium as being the same or in differentiating them from control specimens; both techniques appeared to been superior to antimicrobial susceptibility testing.

TL;DR: Strains from both sources, identified on the basis of serotype and characterization of plasmids carried, were found to be identical.

Evaluation of Isolated Cases of Salmonellosis by Plasmid Profile Analysis: Introduction and Transmission of a Bacterial Clone by Precooked Roast Beef
TL;DR: Examination of S newport strains from other regions and intervals indicated that this strain was introduced into these two states sometime after March 1981, and plasmid profile analysis was useful in studying the epidemiology of isolated cases of salmonellosis due to a sensitive common serotype.
