A presence / absence test for Staphylococcus aureus (S. aureus) involves placing a first generation test sample in a solution that will clot in the presence of S. aureus. The solution contains components that will selectively grow S. aureus and also contains clotting factors that will react with S. aureus, if S. aureus is present in the sample, to clot the solution. Examples of specimen samples that can be tested include nasal swabs and lesion swabs, among others. The test can also be modified to detect the presence or absence of methicillin resistant S. Aureus (MRSA).

The solution contains components that will selectively grow S. aureus and also contains clotting factors that will react with S. aureus, if S. aureus is present in the sample, to clot the solution. Examples of specimen samples that can be tested include nasal swabs and lesion swabs, among others. The test can also be modified to detect the presence or absence of methicillin resistant S. Aureus (MRSA). The addition of micro particles having a size in the range of about 0.1 micron to about 1.0 mm provides localities where the bacteria agglomerate, thereby significantly decreasing the clotting time, and providing a significantly stronger clot. The micro particles can be used in other bacteria tests to accelerate the production of an end result. Such other tests can include a vancomycin-resistant enterococcus test; a Group B Streptococcus test; a test for hemolytic E. coli; and a test for Listeria monocytogenes, to name a few. These tests are all performed in a liquid broth-type reagent mixture and do not necessarily involve clotting of the broth.

A dry mixture, a liquid menstrum, and a method, are described for use in detecting the presence or absence of Methicillin Resistant Staphylococcus aureus (“MRSA”) in a first generation biological or environmental specimen sample. First generation specimen samples that can be analyzed include nasal swabs, lesion swabs, skin swabs, throat swabs, food swabs, tanning salon swabs, gym swabs, restaurant swabs, hotel swabs, and the like. The menstrum and method include an anti-ribosomal antibiotic component that will selectively prevent Methicillin Susceptible Staphylococcus aureus (“MSSA”) from growing in the menstrum, while allowing MRSA to grow in the menstrum. The menstrum also includes components which will stimulate growth of MRSA, plus coagulase reacting factors which will cause the menstrum to clot in the event that MRSA is present in the sample. The menstrum also includes components which will produce a detectable signal in the clot, which signal indicates the presence of MRSA in the sample.

The invention discloses a fluorescence quantification RT-PCR (reverse transcription-polymerase chain reaction) detection kit of a Eurasian avian-like type H1N1 swine influenza virus and an application thereof. By virtue of multiple alignments of sequences, and aiming at conserved gene segments of the Eurasian avian-like type H1N1 swine influenza virus, an A(H1N1) (2009) swine influenza virus, a classical type H1N1 swine influenza virus and a human-derived H1N1 swine influenza virus, a primer and a probe with strong specificity for detecting the Eurasian avian-like type H1N1 swine influenza virus are designed and are used for performing real-time fluorescence RT-PCR detection. Experiment results show that by using the kit provided by the invention to detect the Eurasian avian-like type H1N1 swine influenza virus, the specificity is high, and the detection sensitivity to virus RNA (ribonucleic acid) can reach 4.6*10<-7>ng / reaction, so that tissue samples of nasal swabs, lungs, tracheas and the like of a to-be-detected swine herd can be detected, and chick embryo allantoic fluid can also be detected. The kit is simple to operate, easy to popularize and convenient in basic-level operation and application, and can become a useful detection tool for epidemic disease diagnosis of the Eurasian avian-like type H1N1 swine influenza virus and epidemiologic investigations.
