Veterinary Microbiology

Microbial species identification and analysis

Veterinary microbiology and zoonosis surveillance

Among the current critical challenges faced by veterinary microbiologists is the need to obtain secure species identification of rare and challenging organisms affecting animals, in a timely manner. These microorganisms can be pathogenic to animals, or can be asymptomatic to the animal vector but cause disease in humans, usually via a foodborne route. Control of zoonoses is also implicated in food microbiology, for example for Salmonella and Campylobacter surveillance in the production of eggs and whole milk.

Surveillance of zoonoses and antibiotic resistance

Veterinary-directed surveillance of zoonoses is vital for the control of foodborne pathogens. Monitoring microorganisms in animal primary production using rapid, sensitive identification technologies is required by veterinary microbiologists, to control the incidence and spread of pathogens in the food chain. Surveillance of antibiotic resistance is also a top priority for veterinary microbiologists.

In addition to surveillance, veterinary microbiologists are concerned with animal pathogens. New technologies and vaccines are being continuously developed to treat animals, for diseases such as bovine mastitis, but identification and differentiation of mastitis associated Streptococcus spp. and related species is needed to study outbreaks and discover new treatments.

AOAC-OMA and ISO 16140-6 validation

Bruker’s MALDI Biotyper® (MBT) system, which identifies microorganisms using Matrix-Assisted Laser Desorption/Ionization Time-Of-Flight mass spectrometry (MALDI-TOF MS), has been validated and certified according to the AOAC Official Method of Analysis (OMA) standards, for identification and confirmation of:

  • Salmonella spp., Cronobacter spp., Campylobacter spp. and other gram-negative bacteria
    First Action AOAC Official MethodSM 2017.09
  • Listeria spp., Listeria monocytogenes and other gram-positive bacteria
    First Action AOAC Official MethodSM 2017.10.

The MBT is also ISO 16140-part 6 validated by MicroVal as a complete veterinary and food microbiology solution for the confirmation of:

  • Cronobacter spp.
    Certificate N2017LR72
  • Salmonella spp.
    Certificate N2017LR73
  • Campylobacter spp.
    Certificate N2017LR74
  • Listeria spp. and Listeria monocytogenes
    Certificate N2017LR75.

By utilizing sophisticated technology such as MALDI-TOF MS, veterinary microbiologists can ensure their workflows comply with international regulations.
