MiDOG Animal Diagnostics is pleased to announce the launch of Expanded Testing, an enhancement to the MiDOG All-in-One microbial diagnostic platform designed to provide veterinarians with deeper insight into complex infectious disease cases.
With the addition of parasite detection alongside bacteria, fungi, antimicrobial resistance markers, and virulence-associated factors, Expanded Testing represents one of the most comprehensive sequencing-based infectious disease diagnostics currently available in veterinary medicine.
This new capability was developed to address a common challenge in clinical practice: infections in animals are often complex, polymicrobial, and difficult to fully characterize using traditional diagnostic approaches.
A Broader View of Infection
Veterinary infections rarely involve a single organism. In many cases, multiple microbes and pathogenic mechanisms interact to influence disease progression, treatment response, and recurrence.
Traditional diagnostic methods often rely on culture-based techniques or limited PCR panels that target only a small number of organisms. These approaches can miss slow-growing, fastidious, or unexpected pathogens.
MiDOG Expanded Testing uses next-generation DNA sequencing (NGS) to analyze microbial DNA directly from clinical samples, enabling the detection of a wide spectrum of infectious organisms in a single test.
The platform screens samples against curated genomic reference databases containing:
-
64,800 bacterial genomes
-
4,100 fungal genomes
-
4,300 parasitic and protozoan organisms
This expanded coverage allows veterinarians to identify pathogens that may otherwise remain undetected while providing high-resolution identification across multiple microbial groups.
New Diagnostic Insights with Expanded Testing
MiDOG Expanded Testing provides clinicians with a multi-layered understanding of infection by integrating several critical diagnostic insights into a single report.
Expanded Parasite Detection
The test now includes detection of parasitic and protozoan organisms that may contribute to disease across multiple body systems.
Antimicrobial Resistance Profiling
Detection of antimicrobial resistance genes helps inform treatment decisions and supports more targeted therapeutic strategies.
Biofilm-Associated Markers
Identification of microbial traits linked to biofilm formation, which can contribute to chronic and treatment-resistant infections.
Toxin and Virulence Factor Markers
Detection of microbial genes associated with toxin production and pathogenicity, offering additional context for understanding disease severity.
Together, these insights move diagnostics beyond simply identifying organisms present in a sample and toward understanding how those organisms may be influencing clinical disease.
Supporting Veterinarians Managing Complex Cases
MiDOG Expanded Testing is particularly valuable in cases where infections do not behave predictably or respond to standard treatment approaches. These may include:
-
Chronic or recurrent infections
-
Culture-negative diagnostic results
-
Suspected polymicrobial infections
-
Cases that fail to resolve with standard therapy
-
Complex infections involving exotic, wildlife, or zoological species
By integrating bacteria, fungi, parasites, antimicrobial resistance genes, and virulence-associated features in a single test, clinicians can obtain a more complete picture of the infectious landscape affecting their patients.
Results are typically delivered within two to three business days of sample receipt, enabling veterinarians to move more quickly from diagnostic uncertainty to informed treatment decisions.
Advancing Veterinary Infectious Disease Diagnostics
“Infections in veterinary medicine can become extremely complicated,” said Dr. Michael Kavanagh, DVM, Co-founder of MiDOG Animal Diagnostics. “Expanded Testing allows us to look comprehensively across bacteria, fungi, and parasites in a single test and translate that genomic data into clear, clinically actionable insights.”
Shuiquan Tang, PhD, Chief Scientific Officer at MiDOG, emphasized the importance of comprehensive genomic diagnostics in modern veterinary medicine.
“Whole genome sequencing provides the full picture clinicians need. Animal infections frequently involve polymicrobial communities, biofilm formation, antimicrobial resistance, and previously uncharacterized microbes. Sequencing allows us to capture that complexity and translate it into actionable information for clinicians.”
Designed for All Animal Species
MiDOG Expanded Testing is available for use across companion animals, equine patients, exotic species, wildlife, and zoological collections, supporting veterinarians working in both clinical and research environments.
By expanding detection capabilities and integrating multiple layers of microbial analysis, MiDOG continues to advance the role of DNA sequencing–based diagnostics in veterinary infectious disease management.
Expanded Testing is available immediately for veterinarians seeking deeper insight into complex and non-resolving infections.
