Stay Ahead of Parasites with Diagnostically Superior Screening.

Giardia seems to be everywhere — coast-to-coast, from the beach to the prairies, to the backyard sandbox.   

In a recent study comparing KeyScreen® GI Parasite PCR to O&P testing, KeyScreen detected >3X more Giardia while indicating zoonotic potential.¹ 

KeyScreen® GI Parasite PCR gives you the power to detect Giardia while also differentiating Giardia strains with zoonotic potential. This allows you to not only make clinical management decisions for pets, but also assist in pet-owner conversations, along with supporting these communications in the most vulnerable groups, such as children, pregnant women, the elderly, and the immunocompromised.

Stay in Front of Parasite Emergence 

Parasites are adapting, expanding, and emerging across the U.S. and Canada. Traditional fecal testing has limitations and advanced diagnostics are needed to meet needs and inform risk. 

KeyScreen provides comprehensive screening detection to help you meet today’s dog, cat, and pet owner prevention and treatment needs — including the ability to detect and differentiate one type of parasite from another. For example, the tapeworm Echinococcus multilocularis cannot be differentiated from Taenia without PCR and is a rising One Health concern.³ 

KeyScreen goes beyond simple testing. It provides fecal surveillance that allows dogs to act as sentinels for human risk through detection and differentiation of parasites — as described in a recent collaborative study which adds to the growing body scientific information on tapeworm parasites.³ 

Through the power of big data fecal surveillance, and individual dog and cat cases that come into clinics, KeyScreen is making innovative peer-reviewed science accessible and affordable. This clinically relevant research on parasite frequencies, emergence, and evolution helps you raise risk awareness, talk fecal testing, and inform prevention for your pet owners.  

At Antech, we are committed to supporting veterinary teams because we know that the health and wellness of pets and pet owners are key to everything you do. And that’s true for us, too. 

“The human-pet bond is a strong one, for me too. Our pets are our family, and because of this, diagnostic tests need to advance to protect them, their owners, and the broader community. KeyScreen was designed to help veterinarians screen and choose the right treatment path early…this also helps protect people living in the dogs’ and cats’ environment — which is a key component of the One Health initiative.” 

— KeyScreen inventor Dr. Christian M. Leutenegger, veterinarian, pet-owner and VP of Research and Development at Antech Diagnostics. 

The results on hookworm resistance are in, and they’re concerning. 

KeyScreen® GI Parasite PCR is the only way to stay a step ahead of mutating parasites.^4-7 

KeyScreen leverages the power of molecular diagnostics to find genetic traces of parasites, so you don’t rely on visible evidence alone. You find proof of parasite infection that a microscope cannot see. 

Drug-resistant hookworm infections have been reported in more than 70 dog breeds.^4,5 1 in 10 (11.2%) samples from U.S. dogs with A. caninum infection contained the genetic markers for benzimidazole resistance.⁴ And that’s just in the U.S. Of the Canada dogs with A. caninum infection, 1 in 25 (4.1 %) samples contained the genetic markers for benzimidazole resistance.⁷ 

Routine fecal screening with KeyScreen helps you stay ahead of drug resistance.^4-7  

• The only screening panel in veterinary medicine that can detect benzimidazole-resistant hookworms  
• Demonstrated a 1.4x greater A. caninum detection rate compared to O&P⁷

Advancing Parasite Detection — The Science  

The KeyScreen GI Parasites PCR Panel now has 12 peer-reviewed publications. This paper¹ compares KeyScreen to O&P’s done at a veterinary reference lab, concluding that KeyScreen is diagnostically superior.  

KeyScreen also provided information that went beyond traditional fecal O&P, such as detecting parasites that O&P did not, along with markers important for clinical management and pet-owner communication — like hookworm treatment resistance, and Giardia with zoonotic potential, both Canadian concerns. 

KeyScreen leverages the power of molecular diagnostics (PCR) to detect genetic traces of parasites. With this routine wellness screening PCR test, you find parasite infection in the pets you care for that a microscopic exam can’t. 

Now for the good news — although zoonotic infections, like Echinococcus multilocularis and Baylisascaris procyonis (Racoon Roundworm) are relatively rare, KeyScreen detects them fast...giving you the opportunity to deliver the right care and inform pet-owners on risk.  

Advancing Parasite Detection — The Science  

Hookworms are complex to manage, more prevalent than we thought, and they’ve recently developed drug resistance to our most common treatments. These benzimidazole (e.g.,fenbendazole, febantel) treatment resistant hookworms have recently been found to be widespread throughout the U.S. and are now endemic in Canada.^4,7 

A recent study⁷ using KeyScreen described a series of dogs in different parts of Canada, that were not from the U.S., with the marker for hookworm benzimidazole treatment resistance. 

KeyScreen now contains two types of benzimidazole resistance markers within the parasite PCR test panel in order to broaden fecal detection and awareness of the hookworm A. caninum’s rapidly emerging antimicrobial-anthelmintic resistance. This advanced molecular detection innovation provides veterinary teams with help for treatment selection on this evolving One Health concern and assists with pet owner communication to protect pets, people, and the environment (pick up the poop, please!). 

Case Study: Otis Says “So Long” to Hookworms* 

Experience diagnostically superior GI parasite screening with KeyScreen.   

For veterinarians seeking to ensure positive health outcomes for pets, their families, and the broader pet community, you can find more GI parasites and treat them with precision, speed, and confidence.    

• Screens for 20 intestinal parasites 
• Detects 2x more infections¹ when compared to in-house fecal flotations (O&P) 
• Detects benzimidazole resistance in hookworms 

Determines the zoonotic potential of Giardia 

This is superior, evolving parasite detection.
