This study provides a taxonomic revision of the complex in Vietnam. Based on integrative taxonomic analyses, sensu stricto is distributed in Lao Cai, Vinh Phuc, Ha Giang, and Tuyen Quang provinces. Other records of in northern and central Vietnam revealed to be representatives of two new species: from Son La, Thanh Hoa, and Nghe An provinces and from Quang Binh and Thua Thien Hue provinces. The two new species morphologically differ from each other and from other known species in the genus in size, skin texture, color pattern, and nuptial spines. The molecular analysis based on 16S rRNA and Cytb gene fragments showed that the genetic divergence between and other congeners ranges from 2.96% (compared with and ) to 7.89% (compared with ) in the 16S gene and from 13.81% (compared with ) to 22.91% (compared with sp.) in the Cytb gene, while the p-distances between and its congeners ranges from 2.34% (compared with ) to 6.12% (compared with sp.) in the 16S gene and from 10.15% (compared with ) to 21.88% (compared with ) in the Cytb gene. These new findings bring the total number of known species in the genus to 15 and the recorded species from Vietnam to eight.

Background: The nematode superfamily Strongyloidea represents a prevalent group of gastrointestinal parasites in ruminants and livestock, posing substantial veterinary and economic burdens worldwide. Here we present the first mitochondrial genomic investigation for reconstructing Strongyloidea phylogeny and investigating niche-specific selection dynamics across gastrointestinal habitats (abomasum, small intestine, and large intestine). This study presents a preliminary exploration of the evolutionary adaptations of these agriculturally relevant parasites through comprehensive mitogenomic analysis.

Identifying the diversity of wildlife hosts for malaria parasites in wildlife is crucial for understanding transmission dynamics in endemic regions where humans, vectors, and wildlife heavily overlap. We examined the presence of parasites in free-ranging ring-tailed coatis (, = 44) and nine-banded armadillos (, = 66) from an Indigenous community in the Peruvian Amazon. Nested PCR targeting the mitochondrial gene detected spp.

Historical reconstruction studies are important for understanding the evolutionary mechanisms associated with different parasite-host systems. Platyhelminths of the classes Monopisthocotyla and Polyopisthocotyla (formerly Monogenoidea or Monogenea) have proven to be excellent models for historical reconstruction studies due to their exceptional parasite specificity, suggesting that cospeciation events are the main pattern observed in these parasite-host systems (i.e.

The Trichinella species complex includes 10 recognized species and three genotypes with global distribution, impacting significant health and economic burdens on livestock, wildlife, and humans. In India, trichinellosis is an under recognized zoonotic disease. Investigating the taxonomic status, genetic diversity and phylogeography of Indian Trichinella isolates is crucial for understanding the disease's regional dynamics.

Meat adulteration with undeclared species remains a pervasive problem. We report a rapid, sensitive, and field-deployable assay-termed magnetic nanoparticle-assisted multiplex recombinase polymerase amplification (mRPA) with fluorescence detection for the simultaneous detection of horse and chicken components in meat. It integrates mRPA, streptavidin-coated core-shell FeO@SiO nanoparticles, and dual-labeled primers targeting ATP6-8 (horse) and CYTB (chicken) genes.
