TL;DR: It was concluded that the atypical E. coli colony Types 1 and 2 play a significant role in the PEMS disease. (via Semantic Scholar)

MeSH headings : Animals; Anti-Bacterial Agents / pharmacology; Anti-Infective Agents / pharmacology; Colony Count, Microbial; Drug Resistance, Microbial; Enteritis / microbiology; Enteritis / mortality; Enteritis / veterinary; Escherichia coli / classification; Escherichia coli / drug effects; Escherichia coli / growth & development; Escherichia coli Infections / mortality; Escherichia coli Infections / pathology; Escherichia coli Infections / veterinary; Fluoroquinolones; Kidney / microbiology; Liver / microbiology; Microscopy, Electron / veterinary; Poultry Diseases / microbiology; Poultry Diseases / mortality; Poultry Diseases / pathology; Syndrome; Time Factors; Turkeys

TL;DR: Two colonial types of E. coli are proposed as possible etiological links in the complex series of events that take place in poults susceptible to PEMS and each strain responds to third generation fluoroquinolone antibiotics by changing their biotypes and become resistant after culturing once in their presence.

MeSH headings : Animals; Anti-Bacterial Agents / therapeutic use; Chick Embryo / microbiology; Chickens / microbiology; Combined Modality Therapy / veterinary; Eggs / microbiology; Escherichia coli / isolation & purification; Escherichia coli Infections / epidemiology; Escherichia coli Infections / prevention & control; Escherichia coli Infections / therapy; Gentamicins / therapeutic use; Incidence; Injections / methods; Injections / veterinary; Intestines / microbiology; Intestines / ultrastructure; Lactobacillus / isolation & purification; Lactobacillus / physiology; Microscopy, Electron, Scanning / veterinary; Microvilli / microbiology; Microvilli / ultrastructure; Poultry Diseases / epidemiology; Poultry Diseases / prevention & control; Poultry Diseases / therapy; Salmonella / isolation & purification; Salmonella Infections, Animal / epidemiology; Salmonella Infections, Animal / prevention & control; Salmonella Infections, Animal / therapy; Turkeys / embryology; Turkeys / microbiology

TL;DR: The data that have been presented indicate that the in ovo use of competitive exclusion (CE) agents is feasible for both chickens and turkeys, and only Lactobacillus reuteri has been shown to be safe and effective in terms of not affecting hatchability and in having a prolonged effect in the hatched chick or poult.
