The book "Biofilm Producing Avian Pathogenic E. coli" explores the characteristics and behaviors of a type of E. coli bacteria that is known to cause infections in birds. Specifically, the book focuses on the ability of these bacteria to form biofilms - complex communities of microorganisms that can adhere to surfaces and resist treatment with antibiotics. The book covers the latest research on the topic, including the mechanisms by which biofilm-producing avian pathogenic E. coli evade the immune system, and potential strategies for controlling their spread. The book covers the molecular methods to characterize these isolates, along with antimicrobial susceptibility and associated risk factors. It is an essential resource for researchers, veterinarians, and anyone interested in understanding the biology of these harmful bacteria.
