Rats are rodents commonly found in Thailand that carry various zoonotic pathogens. Bacterial zoonosis can occur in a shared environment between humans and rats, especially in human communities and agricultural areas. , particularly pathogenic and multidrug-resistant strains, is a significant public health concern that is transmitted by rats.

- A parasitic worm infecting rodents, hypothesized to originate from Asia, is commonly found in black rats, brown rats, and house mice.
- The study collected rodent samples from Southeast Asia and Europe between 2008 and 2015, aiming to analyze genetic diversity and evolutionary history using modern molecular techniques.
- Results showed that samples from Thai and Laotian rodents displayed low genetic variation and a clear distinction from other regions, improving understanding of the nematode's genetics.
Article Synopsis
- The study focused on a nematode species from the genus Blanchard found in rainbow water snakes collected in southern Thailand, highlighting its unique characteristics compared to similar species.
- Key distinguishing features include specific morphological traits and molecular analysis confirming it as a new species, genetically separate from previously known nematodes.
- The findings also reveal health concerns, as this new species causes significant lesions in the snakes' stomach, emphasizing the need for better food hygiene and parasite control in captive environments.
is one of the dominant chigger species in Southeast Asia and a potential carrier of scrub typhus, due in part to its cosmopolitan nature. This study explored the possible biological significance of the observed dimorphism in the shape of its scutum sensilla. Sensilla are specialized structures that are generally adapted to perform specific functions related to sensory capabilities, so their shape and sizes are expected to vary between taxa.

Phylogenetic analyses are based on sequences of the large subunit ribosomal RNA gene (28S) and mitochondrial NADH dehydrogenase subunit 1 gene (nad1). The main phylogenetic pattern emerging from the present analysis is the presence of three independent lineages within the main clade of the subfamily Davaineinae, one of which is almost entirely confined to species from rodents and the other two show a mixture of species from birds and mammals.
