dUsing a pan-astrovirus reverse transcription-PCR assay, a great diversity of novel avastroviruses was detected from wild bird and poultry samples. Two groups of astroviruses detected from wild birds are genetically related or highly similar to previously known viruses in poultry. Most interestingly, a novel group of astroviruses was detected in wild aquatic birds. Our results also reveal that different groups of astroviruses might have difference host ranges. This study has expanded our understanding regarding avastrovirus ecology.

In the presence of wound infection from snakebite injury in Hong Kong, first line empirical antibiotics include amoxicillin/clavulanic acid plus levofloxacin. Prophylactic antibiotics may be considered in selected cases of Chinese cobra (N. atra) bite, otherwise prophylactic antibiotics are not recommended in snakebite unless tissue necrosis is present.

Ophidiomycosis (also referred to as snake fungal disease) is an emerging infectious disease caused by Ophidiomyces ophidiicola ( Oo ). PCR was used to detect Oo in a Burmese python ( Python bivittatus ) submitted to a rescue center in Hong Kong with skin lesions. This is the first documented case of ophidiomycosis in Asia and the first detection of this disease in this species. More research is needed in Asia to determine the prevalence of this mycosis, its relationship with other species and its ecological importance. These findings also highlight a significant role played by wildlife rescue centres in monitoring wildlife diseases and ecosystem health

Reference intervals for blood biochemical analytes and packed cell volume are useful to veterinarians and conservation programs for monitoring the health of threatened species. Populations of the critically endangered Chinese three-striped box turtle, Cuora trifasciata (Bell, 1825), are heavily depleted in the wild because of overharvesting; and many individuals are now maintained in captive breeding programs. Reference intervals of biochemical analytes and packed cell volume were established for individuals of this species held in a captive breeding program at Kadoorie Farm and Botanic Garden, Hong Kong. Blood samples were obtained from 86 healthy individuals from a captive population during annual health examinations between 2006 and 2010. Packed cell volume and 17 biochemical analytes were measured, and data were analyzed using both multivariate and univariate statistical analyses. Significant differences in eight analytes between males and females were identified. Ten analytes were found to increase or decrease significantly with the body weight of the turtles. The reported plasma reference intervals, based on 2.5th and 97.5th percentiles, may serve as benchmarks for clinical assessment and conservation of this critically endangered species.
