  • Patent number: 10829826
    Abstract: The present invention is based on the discovery of novel polymorphisms (SNPs) in the penicillin binding protein (pbp3) gene in Staphylococcus aureus. The presence of G88A and/or G2047A SNPs provides an accurate, reliable biomarker for the presence of Methicillin Resistant Staphylococcus aureus (MRSA), specifically the community-associated MRSA (CA-MRSA). The present invention provides reagents used for detecting the SNPs as well as methods of identifying and using these variants to screen subjects for presence of CA-MRSA. The methods involve isolating a biological sample from a mammal (preferably a human) and testing for the presence of a SNP in the pbp3 gene which is associated with CA-MRSA.

  • Publication number: 20170260570
    Abstract: The present invention relates to an antibiotic resistance profile for Neisseria gonorrhoeae by assessing the presence of mutations (e.g., SNP) in antibiotic resistant genes that confer bacterial resistance against antibiotics such as penicillin, tetracycline, fluoroquinolones, cephalosporin, macrolides and spectinomycin. There is provided a method and a kit for generating an antibiotic resistance profile for Neisseria gonorrhoeae by utilizing a multiplex PCR to amplify segments of antibiotic-resistant genes, allele-specific primer extension to detect gene mutation, and detection of such gene mutations with gel electrophoresis, capillary electrophoresis, or DNA microarray. The present method provides useful information to physicians relating the antibiotic susceptibility of Neisseria gonorrhoeae against different classes of antibiotics.

  • Patent number: 8715936
    Abstract: Disclosed are diagnostic methods for determining a subtype of methicillin-resistant Staphylococcus aureus (MRSA) in a biological sample of a mammal. Methods include providing a biological sample of the mammal, performing a PCR analysis of the biological sample, and analyzing the PCR amplicons with respect to their sizes so as to determine for type I, type II, type III, type IV or type V MRSA that may be present in the biological sample. Further example embodiments include using at least one mecA primer pair and/or using at least one Staphylococcus aureus nuc primer pair in the PCR analysis. Further disclosed are methods for screening populations for MRSA, and methods of treating a mammal testing positive for Type IV MRSA. Also disclosed are kits for determining a MRSA subtype in a mammal and isolated primers that may be used in the present methods and kits.

  • Patent number: 8021846
    Abstract: There is disclosed a method for determining azole resistance in Candida glabrata. A biological sample containing Candida glabrata is obtained and a normalized mRNA level of CDR1 gene is determined using qRT-PCR. Using a microbroth dilution assay conducted at azole concentrations of about 2-8 ?g/mL, a susceptible isolate of Candida glabrata is obtained. A qRT-PCR assay is employed on the susceptible isolate and an average mRNA level of CDR1 is obtained. A fold-change value for CDR1 is obtained by comparing the CDR1 mRNA level of the biological sample with that of the average mRNA level. A ?2-fold change value is indicative of an azole resistance in Candida glabrata. The present method provides a qRT-PCR assay for azole resistance that has a sensitivity of ?90% and a specificity of ?90%.
