The study and testing of microbes is important for human health, the safety of our food supply, and the health of our animals.
Why is Pathogen Testing Crucial?
● Study of the Microbiome: The human body is populated by 100 trillion bacteria, archaea, fungi, protists, and viruses, all of which play a fundamental role in our well-being.
● Public Health Protection: Detecting and eliminating pathogens in food prevents outbreaks of foodborne illnesses, safeguarding public health.
● Animal Health: Identifying and controlling veterinary pathogens helps maintain animal well-being and prevents the spread of diseases.
● Economic Impact: Outbreaks of foodborne illnesses and animal diseases can have severe economic consequences for the agriculture and food industries.
● Consumer Confidence: Rigorous testing builds trust in the safety of food products and veterinary and pet care.
Study of Microbiome, Foodborne and Veterinary Pathogens
Microbiome Research
Deviations from healthy microbial compositions have been linked to many human diseases, including inflammatory bowel disease, obesity, cancer, asthma, diabetes, and allergies. For example, panels of biomarkers may be used to study the effectiveness of probiotics in treating gastrointestinal injury and permeability.
Foodborne and Veterinary Pathogens
A vast array of pathogens can contaminate food and infect animals. Various methods are available for detecting bacterial pathogens and can streamline experiments for infectious disease research. Some of the most prevalent microbes include:
○ Salmonella: Causes food poisoning with symptoms like diarrhea, fever, and abdominal cramps.
○ E. coli: Some strains can cause severe illness, including kidney failure.
○ Listeria: Can lead to serious infections in vulnerable populations.
○ Campylobacter: A common cause of foodborne illness.
○ Parvovirus: A highly contagious viral disease in dogs.
○ Enterotoxigenic E. coliK99 is one of the major causes of diarrhea in neonatal pigs, calves and lambs.
○ Salmonella enterica serovar Typhimurium is a primary enteric pathogen infecting both humans and animals.
Advanced Testing Methods
To effectively detect and identify pathogens, BioTether Sciences laboratory employs a range of sophisticated techniques:
● Molecular diagnostics: Rapid and sensitive techniques like PCR (Polymerase Chain Reaction), or Sanger Sequencing to detect specific genetic material of pathogens.
● Immunological methods: Utilize antibodies to detect specific antigens of pathogens. ELISA or ECLA based methods are robust and informative.
● Biochemical methods: Identify microbes by observing the chemical and physical reactions. Some biochemical methods for measuring microbes include enzymatic assays, such as Catalase, or other fluorogenic substate assay.
The Role of Laboratories
Bioanalytical testing laboratories play a critical role in safeguarding public health and animal well-being. They follow strict protocols and adhere to regulatory standards to ensure accurate and reliable results.This includes sample purification of high-quality microbial and host DNA from a wide variety of sample types, including challenging samples such as stool and soil. Testing for veterinary and food pathogens is an indispensable component of ensuring food safety and animal health. By employing advanced testing methods and maintaining high standards, laboratories contribute to protecting public health and fostering consumer confidence.
