Valid Article
Streptococcus A, B, C, D, F, G LATEX AGGLUTINATION(Pastorex)
CAUTION
This test is worded and codified by unit to make the order easier, but it is always packaged in kit of 60.
Definition
PASTOREX STREP is a rapid agglutination test for grouping streptococci according to Lancefield classification. The test involves use of latex suspensions specific for groups A, B, C, D, F, and G.
This kit is only to be used on cultured bacteria, not directly on specimen.
Specifications
Components
Each kit contains:
- Six vials of 1 ml of latex suspension, specific for group A, B, C, D, F, and G streptococci, respectively. The latex particles are coated with group-specific rabbit immunoglobulins.
- Two vials of freeze-dried extraction enzyme. The content of the vial should be reconstituted with 10 ml distilled water.
- One vial of 1.5 ml polyvalent positive control antigen, made of an extracts mixture of Lancefield of group A, B, C, D, F, and G streptococci.
- 3 x 125 disposable rods
- 4 x 15 disposable agglutination cards (8 circles).
Technical specifications
- Specimen: cultured bacteria (not directly on clinical specimen!)
Packaging & Labelling
Kit for 60 tests:
- 6 x 1 ml vials
- 1 x 1.5 ml vial
- 2 bottles of liophilised extraction enzyme
- 60 agglutination cards
- 375 mixing sticks
To be Ordered Separately
- Micropipettes for 40 µl and 300 µl
- Pipettes for 10 ml
- Loop for the collection of bacterial colonies
- Sterile distilled water
- Sterile physiological water
- Hemolysis tubes or micro-tubes (1 per strain to be tested)

Instructions for use
- Let the reagents get to room temperature before starting the test.
- Shake the bottles of latex before use.
- Hold the bottle with latex in vertical position when placing the drop.
- Use a new rod for each reaction.
- Do not touch the reaction surface of the agglutination card.
- Ensure that the caps of the dropper bottles are firmly tightened to avoid contamination or drying of the reagents.
- Use distilled water for reconstitution of enzyme extraction

Precautions for Use
All biological samples must be considered as potentially infectious and handled with the usual precautions (compulsory wearing of gloves, hand washing, etc.).
Avoid any contact with the eyes, skin and mucous membranes (presence of sodium azide).
Storage
- Store between 2°C and 8°C
- Do not freeze
- Not to be used beyond expiry date
- After reconstitution, the extraction enzyme is stable up to 4 months at 2 to 8°C
- Shelf life: 12 months
- Guaranteed minimum remaining shelf life at delivery: 1/3 of the total shelf life
Waste management
After use, sterilise the cultures and all contaminated material.
Presence of substances with hazardous characteristics. Please contact your watsan referent for advice on proper disposal.
Detailed hazard and precautionary information can be found in the safety data sheet (SDS).
