This study was carried out in 2021-2022. By referencing published scientific documents and reviewing museum specimens stored at the Institute of Ecology and Biological Resources, we have established the List of Vietnam Rodents updated to 2022 including 71 species and 22 subspecies of 34 genera and seven families.

The intestinal microbes in mammals play a key role in host metabolism and adaptation. As a subterranean rodent, zokor digs tunnels for foraging and mating. These digging activities of zokors increase the energy expenditure relative to their aboveground counterparts.

Dietary restriction (DR), a reduction in food intake without malnutrition, increases most aspects of health during aging and extends lifespan in diverse species, including rodents. However, the mechanisms by which DR interacts with the aging process to improve health in old age are poorly understood.

Psorergates rattus Fain & Goff, 1986 has been found in the brown rat Rattus norvegicus (Berkenhout, 1769) in Poland. The species has previously been found only once, in the tail base of the brown rat in the United States. In the present case, ten rats from two localities in Poland (Pomerania) were examined and infestation was discovered in 20% of them, with a total of 12 mites found. This is not only the first discovery of the species in Poland and the second globally, but also the first observation of representatives of Psorergatidae in rodents of the genus Rattus in Europe.

In the past decade, many new paramyxoviruses that do not belong to any of the seven established genera in the family Paramyxoviridae have been discovered. Amongst them are J-virus (JPV), Beilong virus (BeiPV) and Tailam virus (TlmPV), three paramyxovirus species found in rodents. Based on their similarities, it has been suggested that these viruses should compose a new genus, tentatively called ‘Jeilongvirus’.

Deer mice (genus Peromyscus) are the most common rodents in North America. Despite the availability of reference genomes for some species, a comprehensive database of polymorphisms, especially in those maintained as living stocks and distributed to academic investigators, is missing.

Subterranean rodents have evolved many features to adapt to their hypoxic environment. The brain is an organ that is particularly vulnerable to damage caused by exposure to hypoxic conditions.

Rodent species in 17 selected localities were determined, and these localities were then compared with respect to rodent species composition. It was determined that a total of 27 rodent species are found in these localities, the number in each locality ranging from 6 to 12. Species previously recorded in mixed and decidous forests in northern Asiatic Turkey.

Rubber was imported into the European market in crude bottles nearly four centuries after the discovery of America by Columbus. This raw material was used for manufacturing crude footwear, waterproof raincoat and other coverings. The sixteenth and seventeenth centuries were a period of incubation in the history of rubber. Europeans considered rubber a curiosity and found no particular use for it. By the end of the eighteenth century four species of rubber-bearing plants had been identified and described (Hevea, H. brasiliensis and H. guianensis; one species of Castilla, C.

In rodents, the olfactory epithelium(OE) canbe divided into four topographically distinct zones, and eachmember of the odorant receptor(OR) gene family is expressed only in one particular zone. To study the functional significance of the zonal structure of the OE, we searched for genes expressed in a zone-specific manner by using the differential display method. Among the clones isolated from the rat OE, we characterized a novel olfactory protein termed O-MACS, a member of the medium-chain acyl-CoA synthetase family....

Abnormal reproductive development in males has been linked to environmen- tal contaminant exposure in a wide variety of vertebrates. These include humans, rodent models, and a large number of comparative wildlife species. In human males, abnormal reproductive development can manifest as a suite of symptoms, described collectively as testicular dysgenesis syndrome (TDS). TDS is also described as demasculinization or feminization of the male phenotype.

In Europe, North America, and especially New Zealand, farmers and foresters have even tried to make use of the powers of weasels for their own ends, particularly to control various “pest” species such as voles (small mouse-like rodents with short tails and small eyes and ears) and rabbits. But the philosophies of weasels and of people toward such situations are quite different: What for us is a problem, requiring elimination, is for weasels an opportunity, to be exploited. That is why biological control by weasels seldom works (Chapters 12, 13).

Though alternative methods of controlling insects, rodents, insect pests, pathogens, microbes and weeds have been developed, pesticides could not be replaced. The prosperous role of pesticides in the management of insect pests and diseases is indisputable. However, its nature of non selective toxicity towards other organisms and deposition in the environment warrants the legislation of usage. Pesticide use raises a number of environmental concerns.

Over the past six decades, tourism has experienced continued expansion and diversification becoming one of the largest and fastest growing economic sectors in the world. Many new destinations have emerged alongside the traditional ones of Europe and North America. In the next years an increase of travelling is expected, and the number of related infections will also be higher (http://www.unwto.org/facts/menu.html). Rickettsioses are an important chapter in the field of travel medicine.
