Kansas State and Iowa State researchers have developed an implant for anaplasmosis vaccine delivery.
R
esearchers at the Kansas State University College of Veterinary
Medicine, in collaboration with Iowa State University, have
developed a new vaccine delivery platform to produce long-lasting
protection against anaplasmosis infections.
Bovine anaplasmosis, caused by the blood-borne parasite
Anaplasma marginale, is the most prevalent tick-transmitted disease
of cattle worldwide and causes significant disease loss to beef
producers in the U.S.
“Currently, a common strategy to control anaplasmosis is to provide
mineral or feed containing the antibiotic chlortetracycline to cattle
on pasture,” says Andrew Curtis, doctoral research assistant in the
laboratory of Hans Coetzee, professor and head of the anatomy and
physiology department.
“This practice has raised concerns about the potential emergence of
antimicrobial resistance in bacteria that may pose a risk to human and
animal health,” Curtis says. “Although there is an experimental vaccine
available to control anaplasmosis, it requires multiple injections and it
has not been evaluated in published research studies.”
The objective of the College of Veterinary Medicine study was to
develop a single-dose implant vaccine platform that provides long-

CELL Guard House 9300G is the result of a very successful flush designed to create high
quality, unique pedigreed cattle with huge numbers. His top side features PBRS Bunk
House, the widely popular, deceased AI sire known for injecting performance and
look into the next generation. On the bottom side is MAGS Dominate Deva, the 2017
high-selling female from the Magness Mile High Elite Sale. His phenotypic
superiority is bolstered by his useful number set including top 25% or better
percentile rankings for weaning weight, yearling weight, calving-ease
maternal, scrotal circumference, marbling and mainstream terminal index.
Study the many positive attributes Guard House brings to the table and
decide where he best fits into your program.
