During IPPE 2022 in Atlanta, Georgia, Sarah Muirhead from Feedstuffs 365 spoke with Amlan leadership about global poultry production trends and the background of Amlan’s natural mineral-based products. During the discussion, Dan Jaffee, President and CEO, Oil-Dri Corporation of America and President and General Manager of Amlan International, described the history of Amlan and the origin of the mineral that is the core of Amlan products.

Other discussion topics included global trends Fred Kao, VP of Global Sales, is observing in the poultry industry. Fred spoke about the increase in antibiotic-free poultry production in Brazil as producers adjust to new EU export requirements and the impact that African Swine Fever has had on poultry product demand in Asia.

Dr. Wade Robey, VP Global Marketing and Product Development, also detailed the benefits of two new Amlan products that were launched at IPPE (International products, not for sale in the US). One product is intended for application in antibiotic-free broiler production when pathogens are decreasing bird performance or when producers are trying to reduce pathogen levels entering the processing plant (NeutraPath®), and the other is a natural alternative to anticoccidial drugs and vaccines (Phylox®) for full time use or in a shuttle program when resistance to traditional coccidiostats is a concern.  Both products also have excellent application potential in broiler breeders which are often challenged with coccidiosis and which can be very sensitive to mycotoxins and bacterial pathogens during grow-out and egg production.

Scientific Expertise and a State-of-the-Art Facility: The Foundation for Developing Amlan’s Natural and Efficacious Products

Still image from INNOVATION NATION interview with Dr. Hongyu Xue MD, PhD, at Research Laboratory.

With cutting-edge equipment and state-of-the-art facilities, Amlan’s talented Life Sciences team creates value-adding mineral-based products for poultry and livestock producers. The Richard M. Jaffee Center for Applied Microbiology houses the specialized equipment used by the Life Sciences team who draw upon their extensive research experience and knowledge base to create novel, natural solutions that improve poultry and livestock health and production efficiency.

Life Science Experts

The Amlan research team is led by Life Sciences Director Hongyu Xue MD, PhD, an experienced scientist in clinical and animal nutrition, who brings a unique point of view to Amlan’s research by leveraging his expertise in human medicine. Dr. Xue has a background in academic medicine and research that cross-links gastroenterology, immunology, microbiology and nutrition. Working with Dr. Xue is a multi-disciplinary team of scientists with expertise across microbiology, animal nutrition, chemistry and material science areas. Several members of the Life Sciences team were recently featured on an episode of “Built in America: INNOVATION NATION” on the Fox Business Network, where they showcased some of their novel research.

Cutting-Edge Equipment

The state-of-the-art equipment in the Richard M. Jaffee Center for Applied Microbiology allows the Life Sciences experts to use a variety of research techniques to develop and assess new mineral-based products for the animal health market.

The Life Sciences team enhances Amlan’s unique mineral to develop natural solutions that can control the microbial pathogens that negatively impact the health and productivity of poultry and livestock. To do this, the scientists study these pathogens and their toxins to understand their physiology and mode of action. Some pathogens require anerobic conditions to survive, so these pathogens are cultivated in Amlan’s anerobic chamber — a more efficient and robust method than alternative techniques such as anerobic jar or pouch systems.   

Conditions within the chamber can perfectly mimic the anerobic environment of the distal gastrointestinal (GI) tract (e.g., ileum and cecum) which serves as the primary colonization site for a vast variety of common microbial pathogens for poultry and livestock. The anaerobic chamber is of tremendous value to help Amlan’s scientists cultivate and further characterize the target pathogens and select commensal microbial populations colonizing the distal GI tract. Further, the chamber also enables the scientists to screen novel products in development and evaluate their antimicrobial effects for certain anaerobic pathogens. Novel strains of beneficial bacteria (probiotics) can also be isolated, grown and tested in the anerobic chamber. The photo below shows an example of the zone of inhibition surrounding an Amlan-developed probiotic (right) versus a water control (left).

Close-up of petri dish.

Further assessment of the new products can be conducted using equipment such as an ICP-OES (inductively coupled plasma-optical emission spectrometer) that allows the team to examine how different cations released by Amlan’s unique mineral affects bacterial virulence. Some metals (cations) are known to suppress the expression of virulence genes in bacterial pathogens.

The lab also includes a fluorescent microscope that enables microbes to be observed instantly to see a product’s effect on bacterial morphology and viability.

Using real-time polymerase chain reaction (PCR), the Life Sciences team have developed methods to detect toxin genes from microbial pathogens that can have negative effects on poultry and livestock production. Using this information, natural solutions can be developed that disarm these pathogens and help protect birds and animals from disease. For example, real-time PCR is used to investigate the effects of new products on pathogen virulence gene expression. Further, this technology can help determine the copy numbers of specific virulence genes and help make an early diagnosis of specific enteric diseases in poultry and livestock.

The Richard M. Jaffee Center for Applied Microbiology is named after the former chairman of Oil-Dri Corporation of America, doing business as Amlan International. Jaffee’s pioneering spirit and vision for Oil-Dri to conduct research in the life sciences is the influence behind Amlan’s focus on developing value-added next-generation animal health products.

An Antivirulence Approach to Controlling Bacteria: AGP Alternatives in Development at the Richard M. Jaffee Center for Applied Microbiology

The rise of multi-drug-resistant and mutant bacteria, which don’t respond to antibiotic treatment, is a concerning trend across the world. With the use of antibiotic growth promoters (AGPs) restricted in an increasing number of countries, livestock and poultry industries are looking for antibiotic-free alternatives that keep animals and birds healthy and productive. Amlan International’s Richard M. Jaffee Center for Applied Microbiology is developing industry-leading technology that helps livestock and poultry producers achieve peak antibiotic-free-performance.

Discovering new methods to combat the prevalence of resistant and mutant pathogens is just one of the topics scientists at the Richard M. Jaffee Center for Applied Microbiology are investigating. The research team at Amlan’s new state-of-the-art lab are using an antivirulence approach to control pathogens, which has also been a research focus for developing new antimicrobial drugs for humans.

Novel Alternative to Antibiotics

Unlike conventional antibiotics, antivirulence approach targets bacterial virulence factors and is aimed at disarming pathogens and modifying their behaviors by making them less harmful (less virulent) to the host. The likelihood for multi-drug-resistant and mutant bacteria is much less using this approach.

There are many options for controlling pathogens using an antivirulence approach. These antivirulence targets include:

  • Toxins
  • Secretion systems
  • Quorum sensing
  • Host-pathogen signaling
  • Adhesins
  • Biofilm formation
  • Siderophores
  • Immune evasion

Previous research at Amlan International showed exciting promise in the quorum sensing area. The Richard M. Jaffee Center for Applied Microbiology continues to conduct quorum sensing research as one component of the overall antivirulence approach to improving livestock and poultry health and production.

Bacteria Can Communicate

Quorum sensing is a communication system between bacterial cells that allows bacteria to regulate their activity in response to stimuli. This communication system involves bacteria releasing biochemicals into the environment which accumulate in the surrounding area until reaching a critical threshold concentration1. The biochemicals then bind to receptors on the bacteria, signaling gene expression.

Quorum sensing can control many functions in bacteria2 including:

  • Bacterial population
  • Virulent gene expression
  • Bioluminescence
  • Pigment generation
  • Bacterial swarming
  • Biofilm formation

Quorum Quenching Silences Bacteria

Quorum quenching is an approach which can disrupt the quorum sensing system of pathogenic bacteria, preventing cell-to-cell communication and the expression of virulence genes that could lead to their infection in the host. Quorum quenching products should reduce the chance of antibiotic resistance, since they are modifying bacteria behavior rather than killing them.

Calibrin®-Z Disrupts Quorum Sensing

Evidence of quorum quenching by Amlan’s Calibrin®‑Z biotoxin control product was published in the Journal of Agricultural and Food Chemistry. The research team at the Richard M. Jaffee Center for Applied Microbiology are continuing to build on these positive results and further quorum sensing research.

The previous study illustrated that in vitro, quorum sensing molecules can be separated out by adsorption or catalytically broken down into small fragments by Calibrin-Z. By reducing the concentration of quorum sensing biochemicals, the products can potentially disrupt the ability of pathogenic bacteria to produce toxins or reduce their virulence, since these functions are controlled through quorum sensing. 

Additionally, due to their stronger acidity, greater pore volume and greater surface area, in the same study Calibrin-Z performed better then silica, illite and kaolinite as catalysts/adsorbents in quorum sensing molecule removal.

When incubated with Vibrio harveyi, a bacterium that exhibits bioluminescence controlled via quorum signaling, Calibrin-Z reduced bacterial luminescence by 55% (from the area under the curve; Figure 1). While this demonstrated that interference in quorum sensing occurred, the bacterial numbers were not impacted, indicating the reduction in bioluminescence was achieved through quorum quenching and not by killing bacteria.

Quorum sensing is just one of the virulence factors being investigated by the research team at the Richard M. Jaffee Center for Applied Microbiology. Similarly, the antivirulence approach is just one of the next-gen technologies that is being developed in the lab to maximize livestock and poultry producer’s profits by improving the health and productivity of their flock or herd.

Richard M. Jaffee Center for Applied Microbiology Laboratory | Amlan International

Products that prevent pathogenic bacteria from communicating with each other? This is just one of the next‑generation technologies that scientists are developing at Amlan International’s innovative new and improved Richard M. Jaffee Center for Applied Microbiology

Amlan’s commitment to microbiology research began when their original laboratory opened in 2017 and further strengthened with the expansion of the Richard M. Jaffee Center for Applied Microbiology in October 2019. The new center provides the company with a cutting‑edge facility to accelerate novel animal health and life sciences research. With state-of-the-art equipment, the R&D team can isolate and cultivate both beneficial and pathogenic bacteria and investigate the antimicrobial effects of Amlan’s next‑generation, natural products.

The new lab is a certified Biosafety Level 2 laboratory, equipped with the technical and diagnostic resources of a traditional microbiology lab, as well as molecular biology, immunology and cell biology capabilities. It’s located near the company’s original R&D center, the Nick Jaffee Center for Innovation in Vernon Hills, Illinois. The 6,000-square-foot facility houses the life sciences team and a high‑tech laboratory space.

Novel Approach to No-Antibiotics-Ever Production

By developing innovative animal health solutions for Amlan’s customers, the research team is simultaneously tackling the global issue of antibiotic resistance. The scientists are using an antivirulence approach to control enteric disease in livestock by developing products that can modify pathogen behavior, making them less virulent (friendlier). This antivirulence approach can improve the production and health of flocks or herds while reducing the tendency to select for resistant or mutant bacteria that is seen with the use of conventional antibiotics.  

“The new lab allows our life science research team to access a wide variety of state-of-the-art equipment, such as real-time PCR, an anaerobic chamber and florescent microscopy,” says Dr. Hongyu Xue, Life Sciences Director at Amlan. “We are trying to disarm the microbial pathogens by targeting their virulence factors in this facility.”

The life sciences team can also analyze the synergistic capabilities of the company’s proprietary enterosorbent mineral formulated with other feed additives, leading to the development of new products that can provide even greater returns on investment for poultry and livestock producers.

By incorporating best production practices, natural feed additive programs and pioneering innovation that targets virulence factors, producers should be able to reduce inputs in animal diets, enhance intestinal health of food animals and improve production efficiency for the entire industry.

“This new lab enables us to bring new ideas and products to the marketplace like never before,” says Flemming Mahs, President, Amlan International. “Science and research are the foundation of our discovery process to improve animal performance by protecting their intestinal health.”
