Test Laboratories

Test Laboratories

Most of the Deltamune Test Laboratories are Department of Agriculture, Forestry and Fisheries (DAFF) approved for diagnosing and monitoring of a list of controlled diseases. All the Test Laboratory are also SANAS ISO 17025 accredited for a wide range of tests.

For more information on the scope of Deltamune’s SANAS accredited tests, refer to the link: sanas.co.za .

Although we offer a range of standard tests to our clients at affordable prices, we are also able to develop new protocols for any additional testing that might be required.

We have branches in Centurion; Oudtshoorn; Malmesbury and Pietermaritzburg and they are all supported by a comprehensive logistics network for sample collection.

Deltamune Test Laboratories have world class solutions, all under one roof.

Diagnostic Testing

Diagnostic Testing

Deltamune has the ability to isolate and identify viruses and bacteria from sick animals using traditional microbiological methods as well as molecular techniques, thus aiding veterinarians in a diagnosis and treatment plan.

The Bacteriology Laboratory can also perform antimicrobial sensitivity tests using the disc diffusion method on those bacteria. Deltamune also performs the much valued Minimum Inhibitory Concentration (MIC) antimicrobial sensitivity test thus enabling the Veterinarian to determine the optimum dose of an antibiotic required for treatment.

Deltamune offers a host of serological test methods to evaluate the presence of antibodies to specific pathogens in the serum of animals, regardless of whether antibodies have developed because of exposure to disease or because of vaccine application. Extent of tests offered: Enzyme Linked Immunosorbent Assay (ELISA), Haemagglutination Inhibition (HI), and Rapid Plate Agglutination (RPA).

To ensure that the results generated in our Serology department are of international standard Deltamune participates in several proficiency schemes conducted by GD Animal Health Service in Deventer, Holland. Deltamune has always generated results within highly acceptable limits for these tests.

  • Serology testing: E.g. Bovine Leucosis, Para-influenza Virus 3 (PI-3), Bovine Respiratory Syncytial Virus (BRSV), Bovine Viral Diarrhoea Virus (BVDV), Q-Fever and Liver Fluke, Newcastle Disease Virus and Avian Influenza Virus

Rapid diagnosis of disease using polymerase chain reaction (PCR) technology is also available: For example, Bluetongue Virus; African Horse sickness; Rift Valley Fever and Lumpy Skin Disease.

Chemical Analytical Testing

Chemical Analytical Testing

The Deltamune Chemical analytical Laboratory can analyse a wide range of products that are exposed to the following:

  • In-Feed medication monitoring
  • Rancidity analysis
  • Mycotoxin Testing
  • Raw material quality control

Our analytical division is equipped with High Performance liquid Chromatography capabilities. The technology is vital for the separation and quantification of various additives used in the food and feed sectors. In addition we are able to detect controlled and poisonous substances.

Environmental Testing

Environmental Testing

Hygiene monitoring of animal production units, processing plants and equipment, plays an important role to ensure optimal production conditions and food safety.

The Hygiene Laboratory can test a wide variety of samples to determine the bacterial load of those samples according to standard testing procedures.

Deltamune offers water analysis for total bacterial counts for E. coli, coliforms, Salmonella spp and Pseudomonas spp which ensures safe water for humans, animal production units, as well as food processing plants.

We test environmental samples including swabs for total bacteria count, E. coli, coliforms, and Pseudomonas spp. as well as Salmonella spp.

We analyse contact & sedimentation plates to determine the bacterial load in a particular area or environment.

At Deltamune we acknowledge that clients need results speedily and we endeavour to complete testing and supply results for routine testing within 7 working days. However, we also know that some results are required more urgently. In cases like these, clients should contact us to organise rapid testing and reporting of samples provided.

Food Safety Testing

Food Safety Testing

Most of the major food retailers listed Deltamune test laboratories as an approved supplier of food safety monitoring tests.

The Food Safety Laboratories can test a wide variety of samples such as feed and feed raw materials, meat and meat products, eggs and egg products and various other foods and food ingredients.

Tests include:

  • Salmonella
  • E. coli
  • Staph aureus
  • Campylobacter
  • Listeria and Pseudomonas
  • Trichinella spp

Our Total bacterial counts are performed with state-of-the-art equipment which ensures accuracy while minimizing the risk of contamination.

Although we offer a range of standard tests to our clients, we are also able to assist with the below:

  • Developing new protocols for any additional testing that might be required.
  • Performing once-off testing for procedure validation according to the client’s needs.

Deltamune has a dedicated laboratory which specialises in Salmonella spp. isolation and identification. The laboratory participates in an international proficiency scheme organised by the Veterinary Laboratory Association in the United Kingdom and we have an outstanding track record in achieving the correct results.
