  4. One of two founders of NutraTech Inc. (July 1999). Its mission was to produce therapeutical antibodies in the egg of laying hans to control intestinal diseases 


1.     Zyme Fast - Antibodies as an Alternative to Antibiotics: 

Zyme Fast, Inc. was incorporated by T. Sellen, L. Fang and R.R. Marquardt. Its mission is to produce therapeutic antibodies for the control and mitigation of intestinal pathogens in animals and humans using antibodies from laying hens hyperimmunized against recombinant expressed virulence factors (specific antigens). The procedure has been shown to be hightly effective at controlling several intestinal pathogens including Clostridium difficile (the hospital pathogen); enterotoxigenic E.coli, and rotovirus in pigs, and pig epidemic diarrhea virus (PEDV) which has recently caused large economic losses in North America. Zyme Fast has also developed proprietory methods for the recombinant production of high concentrations of peptides such as epidermal growth factor (EGF). EGF has been shown to be high effective as a growth promotant in pigs.

2.      All Natural Nutritional Products (ANNP) Inc.:

ANNP's principals are Dr. S. Li and R.R. Marquardt. ANNP's mission is to develop and market nutraceutical supplements that will enhance health and well-being in humans. Currently it has been issued Natural Products Numbers (NPNs) from Health Canada for eight of its products. Several research projects have been funded by NSERC and IRAP (National Research Council).

3.      Research Conducted by R.R. Marquardt since Retirement In 2000:

R.R. Marquardt has published 27 peer-reviewed papers, continued to supervise two Ph.D. students, and served as an Advisor for several Ph.D. candidates. In addition, he has been instrumental in obtaining more than five National grants for research on:

3.1 Production of therapeutic antibodies against intestinal diseases in animals;

3.2 Evaluation of efficacy of EGF in the control of mastitis in lactating cows;

3.3 The development of lateral flow immunologist assays for the detection of Salmonella enteritidis and F4 E.coli;

3.4 The development of a High Performance Liquid Chromatographical (HPLC) method for the simultaneous analyses of resveratrol, quercetin, and emodin in nutraceutical supplements and;

3.5 The identification and isolation of bioactive compounds in Red-Osier dogwood, a unique and highly beneficial native plant.
