Abstract

Organisms adapt and evolve in response to environmental changes. Current changes in the environment occur at a rate and scale that are closer to those of mass extinction rather than of normal, background extinction. The response of species to global changes will depend on their ability to disperse and to acclimatize, as well as on their evolvability. The current view is that the high rate of current environmental changes impedes the evolutionary processes of adaptation to new conditions. Rodents, however, show a high potential to successfully adapt to changing environments over various time scales, including very rapid responses thanks to various characteristics of their life history, traits and plasticity. This paper briefly reviews the processes that allow rodents to respond to the challenges of changing environments, from the instantaneous plastic response to the paleontological perspective of long term evolution. Rodents indeed include very opportunistic and highly evolvable species, which may successfully overcome the ongoing changes, although some specialist species will inevitably be the victim of the adjustment of the communities to the human-driven modification of their environments.

Abstract

Arenaviruses and hantaviruses circulate among the rodent populations of southeast Asia, and can occasionally be transmitted to humans. The latter virus has been identified in human patients in southeast Asia, although the former has not. The case fatality rate due to hemorrhagic fever with renal syndrome (HFRS), caused by hantaviruses and carried by murine rodents, varies between 2–12%, while the case fatality rate due to the arenaviral lymphocytic choriomeningitis virus (LCMV) is lower than 1%. Great care must be taken to avoid infection in pregnant women by LCMV, where serious complications can occur. At present, treatment other than supportive therapy is unavailable for LCMV. A range of vaccines exists in Asia, or are under development for the prevention of hantavirus infection, while ribavirin can help in the early phase of an acute illness. With changing climates and land use and rapidly increasing globalization, it is likely that the situation regarding these zoonotic viruses will change, resulting in an increase in human infections. Few studies have been carried out in this region, particularly in terms of LCMV. More are needed to establish the rates of infection by these agents (and for other potential rodent-borne zoonoses), both in their rodent hosts and in humans, so that they can be used as a baseline to monitor any changes that may occur.

Abstract

The Centre for Thai National Reference Collections (CTNRC) was officially established in 1965, but animal collections in Thailand had been continuously conducted long before this time. This paper gives an historical review of the main steps leading to the constitution of the current collections under the administration of TISTR, with a focus on the rodent collection, which represents about one fifth of the whole mammal specimens. An inventory of the species and genera represented is given. Statistics representing the sampling effort in the different Thai provinces are given. The paper concludes with considerations on the current and future needs and the means necessary to develop and support the efforts of the CTNRC.

Abstract

Rodents have proven to be of increasing importance in transmitting diseases to humans in recent decades, through the emergence of worldwide epidemics and, in Thailand, through the emergence of leptospirosis and scrub typhus. Investigations of parasites and pathogens in murine rodents have helped to describe the implication of the main species and understand the different ways of transmission. From wild to anthropized habitats, rodents can be reservoirs, hosts or vectors of infectious organisms. Related species can react very differently to the same pathogens, with pivotal implications for the understanding of their natural circulation. Scrub typhus is transmitted to humans through the bites of trombiculid mites that have previously fed on infected rodents, generally occurring in wild habitats. Leptospirosis can affect people without any direct contact with infected rodents, but by indirect spread in agricultural areas. Parasitic diseases, such as toxoplasmosis and trypanosomiasis benefit from the proximity of rodents to domesticated animals to jump from one vector to another before reaching humans. By occupying almost all biotopes and by rapidly adapting to environmental changes, rodents are fundamental in the maintenance and transmission of an impressive number of infectious organisms to humans.
