The poultry infections caused by Dispharynx nasuta and Cheilospirura hamulosa nematodes are difficult to be diagnosed by fecal examination because of their egg similarity. In this study, we analyzed DNA sequences of nuclear ribosomal 18S-ITS1-5.8S-ITS2-28S region of D. nasuta and C. hamulosa and developed conventional multiplex PCR method using species-specific primers for discriminating between the two species. The method amplified 455-bp and 319-bp fragments specific to D. nasuta and C. hamulosa, respectively, and did not produce them against the other chicken nematode species, Ascaridia galli, Oxyspirura mansoni, Heterakis gallinarum, Heterakis beramporia, and Heterakis indica, suggesting that the multiplex PCR is sensitive and available for species diagnosis.

Background: This study aims to detect Mycobacterium tuberculosis complex (MTBC) DNA in intraocular fluid from clinically suspected tuberculous uveitis patients using multiplex polymerase chain reaction (PCR) and investigate the diagnostic utility of multiplex PCR for tuberculous uveitis.
Methods: Primers targeting three specific genes (MPB64, CYP141, and IS6110) within the MTBC genome were designed. Multiplex PCR was conducted using DNA from the H37Rv strain as well as DNA extracted from fluids of confirmed tuberculosis patients to assess primer specificity and method feasibility.
Introduction Urinary tract infections (UTIs) are one of the most common bacterial infections encountered in community and healthcare settings. Increasing antimicrobial resistance patterns worldwide have limited the treatment options available. Overuse of carbapenems which were considered as the last resort for multi-drug resistant UTIs over the past decade has led to the emergence of carbapenem-resistant Enterobacterales (CRE).

Coagulase-negative (CoNS) is a rare cause of UTIs in children and is often regarded as a contaminant in urine samples. We report a case of acute focal bacterial nephritis (AFBN) and bacteremia caused by following an upper respiratory infection in a pediatric patient. The patient, a four-year-old girl, presented with fever, cough, and a runny nose two days before being referred to our hospital due to persistent fever and poor oral intake.

Accurate, rapid, and multiplex SNP analysis holds significant clinical value. However, the inevitable nucleic acid extraction, involving centrifugation, heating, and magnetic separation, is often time-consuming. In this study, direct blood PCR was combined with dual-labelled probe-mediated melting curves to identify SNPs corresponding to MTHFR (C677T, rs#1801133 and A1298C, rs#1801131) and MTRR (A66G, rs#1801394) in a single tube.

As astroviral infection rapidly increased in the summer of 2022 in Korea, this study aimed to determine the cause and genotype of astroviruses during this period. From January to December 2022, we tested 43,312 stool samples from patients with acute gastroenteritis utilizing multiplex PCR to detect HAstV. For the HAstV-positive samples, we determined the genotypes of the HAstVs by PCR and sequencing.
