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.
