Recovery of staphylococcal enterotoxin from foods by affinity chromatography.
Extraction, concentration, and serological detection of staphylococcal enterotoxins from foods are laborious and time consuming. By exposing food extracts to an insoluble matrix tagged with specific anti-enterotoxin B, we have been able to recover the toxin from foods in a sensitive and rapid way. After mixing the reagents for 2 h at room temperature, immunoglobulin G antibodies were attached t...
متن کاملEnterotoxin production by Staphylococcus aureus strains isolated from cases of chronic osteomyelitis.
Of 264 Staphylococcus aureus strains selected at random from 3,978 strains isolated from chronic osteomyelitis patients, 79 were found to produce enterotoxin. A majority of the strains (65%) were nontypable by phages belonging to the international phage set for human strain typing. The significance of these strains and their circulation among the population is discussed, especially from the sta...
متن کاملVirulence properties and enterotoxin production of Aeromonas strains isolated from fish.
The biological activities in vivo and in vitro of 59 motile Aeromonas spp. isolated from fish and water tanks were simultaneously analyzed in poikilothermic and homoiothermic systems. A total of 64.3% of the isolates tested were pathogenic for fish, and 62% of Aeromonas hydrophila and A. sobria isolates either virulent or nonvirulent for fish were enterotoxigenic. Although the majority of the s...
متن کاملNo difference in enterotoxin production among Staphylococcus aureus strains isolated from blood compared with strains isolated from healthy carriers.
The production of enterotoxin A, B, C and D by 196 Staphylococcus aureus strains isolated from blood cultures and 95 strains from nasal carriers was investigated. Half of the bacteraemia strains were from patients who died with or because of their infection, the other half from patients who survived. The nasal strains were selected to match the bacteraemia strains regarding phage types. Overall...
متن کاملProduction and Evaluation of Chitosan from Aspergillus Niger MTCC Strains
Three different Aspergillus Niger MTCC strains (872, 1785 and 2208) were used for the production of chitosan. Multivariate growth mediums in varying incubation periods were analyzed for the production. The produced chitosan was characterized by its physical appearance, moisture content (by means of gravimetric method), percentage of ash and solubility (through the Association of Official Agricu...
