A simple and non-expensive platform is critical to realize on-site SNP typing. In this study we typed an SNP existing at the 487th residue of human aldehyde dehydrogenase2 [wild: Glu (GAA); mutant: Lys (AAA)] using our unique isothermal DNA amplification method, ICAN and cycling probes. Both genotypes were identified by the naked eye using a non-expensive UV transilluminator as well as with real-time PCR apparatus or a fluorescence detector. Since ICAN does not need thermal cycling, a cost- and space-limiting factor when fabricating apparatus, the combination of ICAN and cycling probes will be able to realize affordable on-site SNP typing in the near future.

Background: Carbapenem-resistant Acinetobacter baumannii (CRAB) is recognized as a common clinical conditional pathogen with bla gene-mediated multidrug-resistance that is a significant threat to public health safety. Timely and effective infection control measures are needed to prevent their spread.
Methods: We conducted a retrospective study of CRAB patients at three teaching hospitals from 2019 to 2022.

Objectives: Explore the presence, or absence, of virulence genes and the phylogeny of a multi-decade UK collection of clinical and reference Fusobacterium necrophorum isolates.
Methods: Three hundred and eighty-five F. necrophorum strains (1982-2019) were recovered from storage (-80°C).
Evaluation of RMplex system for differentiating father-son pairs using Y-STRs in a Korean population.

Y-chromosomal short tandem repeats (Y-STRs) at rapidly mutating (RM) loci have been suggested as tools for differentiating paternally related males. RMplex is a recently developed system that incorporates 26 RM loci and four fast-mutating (FM) loci, targeting 44 male-specific loci. Here, we evaluated the RMplex by estimating Y-STR mutation rates and the overall differentiation rates for 542 Korean father-son pairs, as well as the genetic population values for 409 unrelated males.

Brucellosis is a neglected zoonotic disease affecting livestock and humans that remains endemic in Ethiopia. Despite its prevalence, only a few studies have identified species circulating in livestock in the country. This study aimed to determine the species responsible for infections in livestock in the Afar region of Ethiopia and characterize the isolates using whole-genome single nucleotide polymorphism (wgSNP) analysis and in silico multi-locus sequence typing (MLST).
