Identifying Immuno-Dominant And Neutralizing Epitopes From K88 Fimbriae Of Enterotoxigenic Escherichia Coli (Etec), T. Lu, W. Zhang Jan 2017

Identifying Immuno-Dominant And Neutralizing Epitopes From K88 Fimbriae Of Enterotoxigenic Escherichia Coli (Etec), T. Lu, W. Zhang

Kansas Agricultural Experiment Station Research Reports

Enterotoxigenic Escherichia coli (ETEC) bacteria are the primary cause of diarrheal disease, especially porcine post-weaning diarrhea (PWD). Post-weaning diarrhea is one of the most common diseases in piglets 3 to 10 days after weaning and causes the loss of millions of dollars annually to United States swine industry and other countries. These ETEC bacteria produce two types of virulence factors: 1) fimbriae adhesins, which promote bacterial attachment and colonization in pig small intestine; and 2) enterotoxins that disrupt fluid homeostasis and cause fluid hype-secretion and watery diarrhea. The F4 (K88) is the most important fimbria in ETEC bacteria causing PWD ...


Differences In Efficacy Between Gamithromycin, Tilmicosin, And Tulathromycin As Metaphylactic Treatments In High Risk Calves For Bovine Respiratory Disease, T. Miller, M. E. Hubbert, E. F. Schwandt, D. U. Thomson, C. D. Reinhardt Jan 2017

The cost of Bovine Respiratory Disease to the beef industry due to death, poorer conversions, and therapy is estimated to cost more than $3 billion per year. Identifying and mitigating Bovine Respiratory Disease in cattle can be difficult due to the increased susceptibility for Bovine Respiratory Disease in high risk cattle. One management option to minimize an outbreak of respiratory disease is the use of metaphylaxis, the mass treatment of a group of calves to reduce the incidence and adverse effects of respiratory disease on high risk animals. Criteria used to determine the necessity of metaphylactic treatment against Bovine Respiratory ...


Zelnate On Arrival Could Decrease The Likelihood Of Subsequent Pulls In Suspect Bovine Respiratory Disease Complex Cases, T. Spore, S. P. Montgomery, G. A. Hanzlicek, W. R. Hollenbeck, R. N. Wahl, J. E. Sears, Dale Blasi Jan 2017

Antimicrobial metaphylaxis is an important tool used for the prevention of Bovine Respiratory Disease Complex; a disease with a large economic impact that typically affects newly-weaned beef calves that are marketed and transported a distance from their origin.

There are questions involving the potential benefit of Zelnate, a novel non-antibiotic technology designed to activate an animal’s natural immunity to fight Bovine Respiratory Disease Complex, being used either solely or in combination with metaphylaxis at the time of initial processing of high risk calves. More knowledge is also needed regarding the possible effects of repeated use of Zelnate when subsequent ...


Genome Diversity And Molecular Detection Of Prrs Field Strains And Vaccine Strains, And Pcv3 And Pcv2 Strains, Y. Wang, F. Yuan, X. Liu, W. Zheng, H. Zhang, J. Zhang, K. Yoon, L. Peddireddi, Y. Fang, G. Anderson, J. Bai Jan 2017

Molecular diagnosis of porcine reproductive and respiratory syndrome virus (PRRS) and porcine circo virus (PCV) are challenging due to high genetic diversity in the viral genomes. Differentiating PRRS vaccine strains is even more challenging and is currently done by DNA sequencing, which is expensive and time-consuming. A multiplexed system (Luminex) allowing multiple detection targets in the same reaction is available. However, this system is not fully developed for common swine pathogens. Therefore, an assay was built to detect the majority of field PRRS strains by using different pairs of primers, and at the same time, to provide differentiation of the ...
