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

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.

หัวเรื่อง:ไม่มีชื่อไทย (ชื่ออังกฤษ : Absorbency and Other Physical Properties of Three Different Rodent Beddings in Thailand)

Abstract

Absorbency and other physical properties of three different rodent bedding materials in Thailand corncob, woodchips, and para-rubber-were tested to find the most appropriate rodent bedding for the NLAC-MU colony. Corncob had the maximum volumetric absorbency after 48 to 72 h soaking in saline. The volumetric absorbency, mass, and density of corncob were significantly higher (p<0.05) than for woodchips and para-rubber (1.5 to 2.5 times). In contrast corncob had the lowest (p<0.05) mass absorbency when compared to woodchips and para-rubber, due to its mass. Autoclaving influenced some properties of corncob bedding due to a reduction in the mass, density, and absorbency. However similar change were not found in woodchips or para-rubber. Woodchips generated significantly more (p<0.05) dust particles than para-rubber and corncob respectively. Perimeter (mm) /area (mm2), and wood fiber space (?m) were used to measure the altered shape after soaking in saline. The results showed that all the bedding used in this study did not significantly change (p>0.05) in shape and preserved its hardness after soaking. The study concluded that corncob and para-rubber were more appropriate for use as rodent bedding than woodchips. Further studies were needed to carry out toxicity, gas production and preference testing.

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 are a significant problem to farmers in upland agricultural systems in Lao PDR. They are considered as the second most important pest after insects because they are the least controlled. There is little known about the factors that influence the breeding activity or changes in population numbers of the main rodent pest species in Lao PDR. There are a minimum of 21 species of murid rodents in Lao PDR, with six considered as important crop pests, among them being Rattus rattus. The other species generally cause little crop damage and are important for their conservation value in the upland forests. Trapping data revealed that the population abundance and breeding activity of rats changed over time in response to the availability of food resources. Peaks in population abundance in the field occurred during the harvest of wet season crops. Rodents then moved into village habitats, where population abundance was high during the fallow and early growing stages. Breeding activity was evident at all stages in the village, with a peak during the fallow stage, when abundant food was available in village stores. Little breeding was observed in the field during the fallow period, increasing to only moderate levels during the growing and harvesting stages. The village habitat is considered as an important habitat for rodents. Management needs to be focussed on limiting the movement of rodents between villages and fields and this needs to be conducted prior to the onset of breeding activity in the field.

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.
