    The distribution of Kitti's Hog-nosed Bat (Craseonycteris thonglongyai) was conducted in Saiyok District, Kanchanaburi Province using harp traps between April 2010 and April 2013. This species was found in 11 out of 24 caves; 9 in military area and 2 in conservation area. A total of 672 bats were captured in this survey. The length of the bat forearms were 23.0-26.3 mm and adults weighed between 1.22 and 5.94 g. Results of this study provide information for conservation of this bat in the area.

    The investigation of ectoparasitic fauna on birds and volant and nonvolant small mammals at srinakarin dam Kanchanaburi province Thailand was carried out under a national biodiversity and disease surveillance program for four consecutive months: January February May and june 2009. a total of 122 animals Comprised of 15 species of birds, 9 species of volant small mammals and 8 species of non-volant small mammals were examined for ectoparasite infestation. of these animals 1 genus of hard ticks (ixodidae), 2 species of mesostigmatid mites (laelapidae), 4 genera in three families of astigmatid mites (proctophyllodidae, Pteronyssidae and trouessartiidae),4 species in three families of lice (philopteridae Polyplacidae and trichodectidae) and 2 families of batflies (nycteribiidae and streblidae) were collected. This is the first survey conducted to determine ectoparasites infesting birds and small mammals living in the reserved forest of srinakarin dam Thailand. a lower infestation rate of ectoparasites was observed in mammals, Ranging from 3.5% to 10.3% than birds With infestation rates between 7.3% and 34.2%. no major potential health risks to people who lived in this area were found.

    Background. Rodents are recognized as hosts for at least 60 zoonotic diseases and may represent a serious threat for human health. In the context of global environmental changes and increasing mobility of humans and animals, contacts between pathogens and potential animal hosts and vectors are modified, amplifying the risk of disease emergence. An accurate identification of each rodent at a specific level is needed in order to understand their implications in the transmission of diseases. Among the Muridae, the Rattini tribe encompasses 167 species inhabiting South East Asia, a hotspot of both biodiversity and emerging and re-emerging diseases. The region faces growing economical development that affects habitats, biodiversity and health. Rat species have been demonstrated as significant hosts of pathogens but are still difficult to recognize at a specific level using morphological criteria. DNA-barcoding methods appear as accurate tools for rat species identification but their use is hampered by the need of reliable identification of reference specimens. In this study, we explore and highlight the limits of the current taxonomy of the Rattini tribe. Results. We used the DNA sequence information itself as the primary information source to establish group membership and estimate putative species boundaries. We sequenced two mitochondrial and one nuclear genes from 122 rat samples to perform phylogenetic reconstructions. The method of Pons and colleagues (2006) that determines, with no prior expectations, the locations of ancestral nodes defining putative species was then applied to our dataset. To give an appropriate name to each cluster recognized as a putative species, we reviewed information from the literature and obtained sequences from a museum holotype specimen following the ancient DNA criteria. Conclusions. Using a recently developed methodology, this study succeeds in refining the taxonomy of one of the most difficult groups of mammals. Most of the species expected within the area were retrieved but new putative species limits were also indicated, in particular within Berylmys and Rattus genera, where future taxonomic studies should be directed. Our study lays the foundations to better investigate rodent-born diseases in South East Asia and illustrates the relevance of evolutionary studies for health and medical sciences. © 2010 Pagès et al; licensee BioMed Central Ltd.
