The field of molecular microbiology has made noticeable advancements over the years, to the point where molecular bacteria testing can now be done to detect pathogens that would otherwise be difficult to detect. Testing of this nature is typically used for microbial identification and detailed typing that goes beyond the species level. Molecular bacteria testing also allows results to be produced faster since multiple forms of bacteria can be detected.

Molecular Bacteria Test Procedures

Molecular bacteria testing involves a detailed examination of the various parts of genes and cell structures to identify specific patterns for the purpose of species identification and typing. Nucleic acid amplification and detection is a common technique used for detection and identification. Real-time PCR is a testing technique that can be both qualitative and quantitative, meaning the type of bacteria can be identified and the results will also show specific levels of bacteria in a sample. The quality and quantity of RNA can also be examined to further identify bacteria that may be difficult to detect through other testing methods.

Molecular Bacteria Sample Collection

While a standard blood sample can be tested, it may be more appropriate to use saliva samples or throat cultures, as would be the case if a physician were looking to identify the specific bacteria involved for a patient with streptococcal pharyngitis (strep throat). Precise detection is important because there are hundreds of strains of streptococcus bacteria. Identifying the correct one will allow a doctor to determine a treatment that will likely be effective. Tissue samples may be taken to identify a respiratory infection. Stool samples are sometimes collected to identify a particular strain of E coli bacteria since it's normally found in the intestines.

Reasons for Molecular Bacteria Testing

Going beyond species identification is often necessary when multiple strains of the same type of bacteria may be making an individual sick. Test results can be used to identify patterns based on geographic locations. For instance, if there is an outbreak of an infectious disease, it's important for health officials to know what type of bacteria is involved so steps can be taken to prevent it from spreading. Molecular bacteria testing may also be requested if a patient isn't responding to standard treatments for a bacteria-related infection that may have become resistant to antibiotics or if it's necessary to trace the source of contaminants to a specific location or manufacturing process.

Reducing Dependence on Antibiotics

A growing concern among scientists is the increase of infections that don't respond well to common antibiotic treatments. There have been several situations in recent years where bacteria-based infections have become increasingly resistant to antibiotics. Molecular bacteria testing may allow doctors to prescribe the correct medication for the particular strain and type of bacteria involved to allow for less-reliance on prolonged doses of antibiotics.

Patients, physicians, and health officials can count on results from molecular bacteria testing done at Genesis Molecular Diagnostics to make well-informed health decisions. There are many modern and effective molecular techniques we employ at our laboratory to help improve the accuracy of bacteria detection. Tests are conducted on-site at our lab and reports are available online.
