CRM006 Chromogenic Enterobacter Sakazakii Agar

Description

Attogene’s Montmorillonite Bentonite Clay binds toxins with high affinity and high capacity.  Montmorillonite has been shown to be the active ingredient in bentonites.  The proposed mechanism of action of Attogene’s Montmorillonite Bentonite Clay is through the adsorption of toxins (mainly onto the interlayer spaces of montmorillonite).  Attogene’s Montmorillonite Bentonite Clay is a common anti-caking agent in animal feeds to adsorb aflatoxins and diminish their bioavailability. Its composite for application in drug system can be formed through the utilization of anionic, cationic, and nonionic surfactants.

Bentonite is a promising rock of clay which is found in nature. It is a major source of montmorillonite in nature. It is a rock produced of highly colloidal and plastic clays mainly comprised of montmorillonite. In addition to montmorillonite, bentonite may compose of some amount of crystalline quarz, cristobalite, and feldspar. Montmorillonite nanoclay is used as a drug carrier system and as an additive. Its composite for application in drug system can be formed through the utilization of anionic, cationic, and nonionic surfactants. These are used to improve basal spacing resulting in organo clay to be utilised in drug loading and drug release.

Promotes flocculation of cyanobacteria cell debris, binds residual phosphate compounds and promotes gradual settling of the cyanobacterial biomass on the sediment.

Description

Not all cyanobacterial strains produce toxins. However, the toxin-producing strains cannot be distinguished from the nontoxin-producing strains by traditional light microscopy, commonlyused to monitor water bodies.  An alternative for the differentiation of potentially toxic strains from nontoxic strains is to use molecular methods to detect the presence of toxin biosynthetic genes. Such methods are already available and could be used for the detection and identification of potential microcystin and nodularin producers present in environmental samples (Attogene catalog number NA2024).

Screening for the toxin itself, can be very costly.  In turn, real time PCR for the detection of a gene region responsible for assembling  in cyanobacterial strains and environmental samples can be a key indicator for the prescense of cyanobacteria capable of expressing the aetokthonotoxin toxin.  Attogen has thus, designed primer pairs and probes targeting a the conserved gene region in order to enable the amplification and detection of several producer genera using real time PCR.  Screening for the toxin genes can save significant costs and act as a triage for samples needing to be analyzed for the toxin itself.

Cyanobacterial neurotoxin aetokthonotoxin (AETX), a peculiar pentabrominated biindole alkaloid implicated in fatal Vacuolar Myelinopathy.  This neurodegenerative disease was first recorded in 1994 during an outbreak of bald-eagle poisonings at De Gray Lake in Arkansas, USA.  AETX was experimentally confirmed to be produced by the true branching heterocytous cyanobacterium Aetokthonos hydrillicola.  The production of AETX is dependent on bromide (Br−) availability, and likely linked to its hyper-accumulation by the host plan.  Thus regular monitoring of A. hydrillicola (accompanied by assessment of Br− and AETX levels) is highly advisable to predict the possible threat of further VM outbreaks.

The cyanobacterial AetA gene which encodes the unique FAD-dependent halogenase involved in the pathway for AETX synthesis has been adapted to develop a -aetokthonotoxin specific quantitative PCR (qPCR) assay.
