Questions remain around the transmission of highly pathogenic avian influenza into and within poultry houses, but the infectious nature of the virus is its biggest weapon, according to a USDA expert.
Controlling IBV through vaccination requires knowledge of the circulating field strains. For this reason, surveillance is critical. Mark W. Jackwood, PhD, and Jose Linares, DVM, describe Ceva’s Scientific Support and Investigation Unit that uses real-time quantitative RT-PCR panels to rapidly detect multiple IBV types.
Enterococcus cecorum was first reported in the US in 2009. Disease caused by this pathogen poses considerable welfare and economic challenges for broiler producers and currently has no effective antibiotic-free treatment. For the past 15 years, Mitsu Suyemoto, research specialist at North Carolina State University, has conducting pioneering research on this emerging pathogen with Luke Borst, DVM, PhD. Of note, their team developed many of the key assays used to study E. cecorum today.
Research led by Phillip Yeboah, PhD candidate at North Carolina State University examined autofluorescence as a method for determining whether Eimeria oocysts are viable and capable of causing infection.
Adding organic acids to poultry drinking water has been suggested as a potential intervention in managing Salmonella, but research by Auburn University scientists showed otherwise.
The emergence of aMPV subtypes A and B has left US poultry producers seeking new tools to reduce the economic impact of this disease. In an interview, Silke Rautenschlein, PhD, professor at the University of Veterinary Medicine in Hannover, Germany, covers the past, present and future of the virus and its control.

Brian Jordan, PhD, associate professor at the University of Georgia joined T.J. Gaydos, DVM, and Rodrigo Gallardo, DVM, PhD, as panelists in a webinar from the AAAP. They discussed the challenges and promises of IBV serotyping with qPCR and sequencing.
Emily Kimminau, PhD, has firmly become one of the industry’s go-to specialists in coccidiosis — a disease that remains one of the most prevalent and costly challenges in global poultry production. In this Q&A, she talks about disease trends, gut health strategies and what the future holds for data-driven poultry production.
Infectious coryza, a bacterial upper respiratory disease, is on the rise in the US. Avibacterium paragallinarum, which is a primary pathogen of chickens causing coryza, spread from southern states to Pennsylvania in 2018, followed by Ohio, Iowa and other northern states.
An innovative vaccine designed to protect broilers against increasingly virulent forms of Marek’s Disease is helping producers rethink how they approach immune health, and how they use data to diagnose problems before they’re visible in the flock.
