Test sui microrganismi

Supplier: VWR Chemicals

Nei laboratori microbiologici è necessario adottare procedure semplici per la conservazione di microrganismi anziché ricorrere alle subcolture ripetute che possono generare colture contaminate, perdita di vitalità e, ancora più grave, perdita delle caratteristiche originali per introduzione di alterazioni biochimiche e genetiche. Cryoinstant è composto da 25 perle porose in una fiala riempita di brodo contenente glicerina. I microrganismi si legano alla superficie porosa delle perle. L'eccesso di brodo viene aspirato, quindi le fiale possono essere conservate in congelatori a temperature fino a –70 °C.

Sucrose is used as a source of energy readily available for bacteria in fermentation tests (i.e. Klebsiella pneumoniae ferments sucrose whilst Salmonella typhimurium gives a negative reaction). It free from other sugars and from starch, proteins and metals. Sucrose can be used as an ingredient of dehydrated culture media and need dissolution in distilled or deionised water and sterilisation by autoclaving.

Serratia species are implicated in nosocomial infections. In several countries, Serratia marcescens is frequently associated with epidemics in intensive care units and in particular in neonatal and pediatric units. Surveillance of nosocomial infections requires effective recovery of clinical isolates from faeces, wound exudates and respiratory samples to prevent problems of cross infection and potentially fatal infections. In this context, CHROMagar™ has developed CHROMagar™ Serratia, a culture medium perfectly suited to the search for S. marcescens in faeces. In addition, S. marcescens is able to survive days to months on surfaces, distilled water and hand soap, making it an important pathogen in nosocomial infections and sporadic epidemics.

Microbiology labs often require a straightforward method for long-term frozen storage of microorganisms for preserving key microbial strains without relying on frequent sub-culturing. Each vial contains tryptic soy broth +15% glycerol. This liquid guarantees the long-term frozen storage of microorganisms.

The SLYM-BARTs can be used as a P/A test capable of indicating to some extent the possible population size and the types of slime-forming organisms present in the water sample. Slime-forming bacteria are able to produce copious amounts of slime without necessarily having to use any iron. Iron bacteria also produce slime, but usually it is thinner and involves the accumulation of various forms of iron. BART biodetectors are excellent diagnostic tools to help identify the presence of process disruptors, such as bacteria creating slime layers and limiting disinfection.
