    “…Molecular identification of virulence factors and antibiotic resistance genes (ARGs) was carried out through polymerase chain reaction (PCR) by using specific primers. For bacteriophage isolation, hospital sewage samples were processed for phage enrichment, purification, and further characterization ie, transmission electron microscopy (TEM) and stability testing, etc. followed by evaluation of the lytic potential of the phage. …”

    “…For Aptima HPV‐negative women with high‐grade cytology or histological high‐grade squamous intraepithelial lesions (HSILs), we performed extended HPV typing for 40 HPV types with polymerase chain reaction using modified GP5+/6+ primers followed by a Luminex assay. To estimate the added cost of using cytology to identify each histologically confirmed cervical HSIL case among Aptima HPV‐negative women, we used the current cost of €21.2 per cytology evaluation at our laboratory. …”

    “…The assay is also specific with 6 degenerate primers targeting every strain of C. Liberibacter asiaticus omp from GenBank database, rapid (40 min total assay time), inexpensive (~2–3 USD/reaction), does not require sophisticated instrumentation, and has comparable assay accuracy (93.85–100% accuracy, 100% specificity, and 89.74–100% sensitivity) to bacterial DNA extraction by a commercial kit followed by PCR and gel electrophoresis (92.31% accuracy, 100% specificity, and 87.18% sensitivity) based on the real sample tests. …”

    “…Here, we present results from SpikeSeq, the first published Sanger sequencing-based method for the detection of Variants of Concern (VOC) and key mutations, using a 1 kb amplicon from the recognized ARTIC Network primers. The proposed setup relies entirely on materials and methods already in use in diagnostic RT-qPCR labs and on existing commercial infrastructure offering sequencing services. …”

    “…Infants defined as NEC were those who presented with clinical courses consistent with NEC and whose radiographs fulfilled criteria for Bell’s stage 2 or 3 NEC, while those who were healthy in appearance and had blood in the stool (visible or may be microscopic), had normal bowel sounds in physical examination, were resolved after eliminating the causative food, and/or had recurrence of symptoms after oral food challenge (OFC) were defined as FPIAP. Primers specific for bacterial 16S rRNA genes were used to amplify and pyrosequence fecal DNA from stool samples. …”

    “…MATERIALS AND METHODS: In a case-control study, CD44-rs8193C>T genotyping of the 420 prostate neoplasms (210 benign prostatic hyperplasia (BPH) patients and 210 prostate cancer patients) and 150 healthy samples are performed by the touchdown polymerase chain reaction with confronting two-pair primers (PCR-CTPP) method. The T mutant allele effects on the mRNA structure and cell pathways were also investigated in silico methods. …”

    “…Additionally, 74 simple sequence repeats (SSRs) were identified within 19 DoCCRs, located in the intron or untranslated regions (UTRs), and mononucleotide predominated. A pair of primers with high polymorphism and good interspecific generality was successfully developed from these SSRs, and 7 alleles were amplified in 105 wild D. odorifera trees from 17 areas covering its whole native distribution. …”

Sequences of mutant genotypes of O. sinensis were aligned with that of Genotype #1 Hirsutella sinensis and compared phylogenetically using a Bayesian majority-rule method. …”
