Microbiological Testing
Culture-Based Analyses for Environmental, Product, and Water Samples
Zenith Laboratories offers a full range of microbiological services designed to identify, enumerate, and characterize microorganisms for contamination control, quality assurance, and compliance purposes.
Culture and microscopic techniques for accurate microbial identification from environmental or product samples.
Analyses Offered:
Bacterial Identification (Culturable) – Isolation on selective media followed by morphological and biochemical characterization.
Fungal Identification (Culturable) – Isolation on SDA or MEA media and microscopic identification of dominant fungal species (Top 3).
Candida auris Detection – Targeted detection by culture or PCR assay (inquire for other Candida species).
Gram Stain – Bacterial Gram classification.
DNA-Based Confirmation (PCR & Sequencing) – Molecular confirmation of bacterial or fungal isolates.
Microbial evaluation of water sources for regulatory and health compliance.
Analyses Offered:
Total & Fecal Coliforms (Membrane Filtration) – Enumeration of coliform bacteria.
E. coli Detection – Membrane filtration or PCR-based identification.
Heterotrophic Plate Count (HPC) – Quantification of bacterial populations using spread plate or pour plate techniques.
Legionella Detection – Culturable (ISO 11731:2017) or PCR-based detection methods.
Species-Specific Pathogen Detection – Identification of waterborne pathogens (Cryptosporidium, Giardia, Candida) via culture or molecular techniques.
Challenge Testing (Custom Design) – Determination of microbial reduction after disinfection or sterilization.
Environmental Isolate Characterization – Identification and typing of site-specific microbial isolates.
Antimicrobial Effectiveness Testing – Verification of sanitizer or disinfectant performance under controlled conditions.
