Staphylococcus Aureus Water Analysis
Staphylococcus aureus is a Gram-positive coccus often associated with various infections. Globally, S. aureus contamination of wastewater is estimated to cause millions of gastrointestinal and acute respiratory infections and numerous skin infections annually. At present, the water quality standards of many countries around the world have made strict regulations on the detection of Staphylococcus aureus. Mastering the pollution status of Staphylococcus in water is very important for effective control of water-borne infectious diseases.
BOC Sciences helps customers analyze Staphylococcus aureus contamination and some other parameters such as temperature, pH, residual chlorine and opacity. We can also examine what levels of S. aureus may be causing the onset of symptoms of staphylococcal infection through further studies (for example, drug resistance assays) and determine appropriate limits.
Service and Technology
Starting with sample analysis, we offer a range of related tests. All tests are performed by professional experimenters to ensure the accuracy and repeatability of the results.
Basic physical and chemical analysis
Measure the temperature using a Celsius mercury scale thermometer. pH and salinity are measured in the laboratory using a pH meter and conductivity meter, respectively. Likewise, turbidity is measured in the laboratory using an optical instrument nephelometer.
Staphylococcus aureus analysis
We aim to utilize faster procedures and a more selective approach, without the need for additional confirmatory testing, which will also lead to better, more reliable data and more timely results.
Detection of specific genes of Staphylococcus aureus
| Target gene | Introduction | Features |
| nuc gene | The nuc gene is a gene encoding thermostable nuclease, located on the chromosome, the length of the gene is 966 bp | Nuc gene specificity is high |
| coa gene | The coa gene encodes plasma coagulase, the coa gene is located on the chromosome, and the length of the gene is 1911 bp | There are a small number of Staphylococcus aureus that do not produce coagulase, and some coagulase-negative bacteria are also highly pathogenic. There are changes in the 3' end coding gene of the coa gene, so the coa gene has many different forms of alleles |
| femA gene | The femA gene encodes a cytoplasmic protein, which is a unique auxiliary gene of S. aureus and can enhance the drug resistance of S. aureus. femA is located on the chromosomal DNA, the length is 1302 bp | The femA gene is polymorphic |
| femB gene | The femB gene encodes a protein of 419 amino acids with a length of 1259 bp, which is a highly conserved specific chromosomal marker | It is a marker sequence that distinguishes Staphylococcus aureus from other staphylococci |
| Enterotoxin gene | Enterotoxin is a unique exotoxin produced by Staphylococcus aureus. A strain can produce two or more enterotoxins, and the genes of most enterotoxins are located on the chromosome | Different enterotoxin genes occur at different rates in S. aureus, and there is not one type of enterotoxin gene common to all S. aureus strains |
| Sa442 gene | Genomic DNA of different strains of Staphylococcus aureus was digested with nucleic acid restriction endonuclease Sau3A I, and a fragment of 442 bp could be obtained | Gene Sa442 is a highly conserved deliberate sequence in Staphylococcus aureus |
Our laboratory is accredited by professional committees, and the test data can be recognized internationally. It is a testing institution that provides water quality evaluation for the society. We have rich experience in water microbial detection and have a high reputation in the world. We can conduct professional Staphylococcus aureus detection and microbial contamination analysis according to national standards, industry standards, local standards and other testing methods.
