Skin diseases affect millions of people and animals worldwide, including Asian elephants. This study sought to determine the pathogen of skin diseases that occurred in Asian elephants in Chongqing Zoo, China. The isolated fungus was identified through its cultural characteristics, morphology, and polymerase chain reaction (PCR) amplification. The PCR amplification using common fungal primers (ITS1 and ITS4) determined that the pathogen was 99.7% homologous to Microsporum canis. This is the first report on elephants infected with Microsporum canis in China. © 2016 by American Association of Zoo Veterinarians.

In order to investigate the mitochondrial genome of Panthera tigris amoyensis, two South China tigers (P25 and P27) were analyzed following 15 cymt-specific primer sets. The entire mtDNA sequence was found to be 16,957 bp and 17,001 bp long for P25 and P27 respectively, and this difference in length between P25 and P27 occurred in the number of tandem repeats in the RS-3 segment of the control region. The structural characteristics of complete P. t. amoyensis mitochondrial genomes were also highly similar to those of P. uncia. Additionally, the rate of point mutation was only 0.3% and a total of 59 variable sites between P25 and P27 were found. Out of the 59 variable sites, 6 were located in 6 different tRNA genes, 6 in the 2 rRNA genes, 7 in non-coding regions (one located between tRNA-Asn and tRNA-Tyr and six in the D-loop), and 40 in 10 protein-coding genes. COI held the largest amount of variable sites (9 sites) and Cytb contained the highest variable rate (0.7%) in the complete sequences. Moreover, out of the 40 variable sites located in 10 protein-coding genes, 12 sites were nonsynonymous. © 2010 Springer Science+Business Media B.V.

In order to figure out the status of biodiversity restoration and distribution characteristics, we applied ArcGIS 9.3 software system to establish a GIS database for the ecological distribution of 66 species of birds under state key protection belonging to nine orders, and analyzed the distribution trend at different periods. The results showed that the overall distribution of the rare birds was concentrated around original forests with high quality vegetation, reservoirs and big rivers in mountainous areas, city parks and woodlands with less human disturbance in plain areas; however, there was no distribution in farmland areas. Comparing the ecological distribution sites of birds under State Key Protection Class I before and after the 1990s, it was found that the distribution was sparse, but three new species appeared after the 1990s, namely Chinese merganser (Mergus squamatus), brown eared pheasant (Crossoptilon mantchuricum) and relict gull (Larus relictus). Furthermore, the distribution sites of previous threeorders expanded. The birds under State Key Protection Class II also had an expansion trend in distribution with two new species of the hazel grouse (Bonasa bonasia) and demoiselle crane (Grus virgo); however, the black tern (Chlidonias niger) and black-faced spoonbill (Platalea minor) could not be found. The above results revealed that there is a positive recover for the overall distribution of the rare birds with the restoration of forests and wetlands in Beijing. The fact that some species disappeared recently indicated that protection of the habitat of wildlife is still a long-term process of constructing ecological environment. The GIS database lays the groundwork for building the management platform of rare wild animal distributions in Beijing, and possesses the important applicable value for the measures of protecting the wild animal populations and their habitats at landscape level. ©, 2015, Beijing Forestry University.

This study aimed to investigate the safety and efficacy of Chinese medicine SH mixture on respiratory tract inflammation induced by herpesvirus. The clinical symptoms, mortality and incidence were observed to evaluate the preventive and therapeutic effects of SH mixture on infectious laryngotracheitis (ILT) in peacocks. Administration of SH mixture noticeably improved the clinical symptoms and decreased the mortality associated with ILT in peacocks. SH mixture also had a significant preventive effect on ILT. The results suggest that SH mixture has preventative and therapeutic effects on respiratory inflammation caused by herpesvirus. Improvement of immune and hematopoietic functions is possibly involved in its protective mechanism.

Asian elephants in Chongqing zoo were repeatedly affected by fungal skin disease recent years. This study sought to establish New Zealand rabbit models infected with Microsporum canis which was pathogens of fungal skin disease developed in Asian elephants in Chongqing zoo. Bacterial colonies were incubated in Sabouraud dextrose agar at 28 ° C for 14 days and then prepared into bacterial suspension and inoculated on the dorsal skin of the rabbits. After 10 days inoculation, the affected skin of rabbits developed advent clinical symptoms such as scab and desquamation that were extremely similar to those of fungal skin disease in Asian elephants. The skin tissue at a size of 1 × 1 cm was collected. The paraffin section was prepared and stained for argentaffin. The pathological section showed that brown orange Microsporum canis was visible in skin tissue after argentaffin staining. The results showed that pathological New Zealand rabbit model for infection with pathogens of fungal skin disease developed in Asian elephants in Chongqing zoo was successfully established. © Medwell Journals, 2014.

Previous studies have shown that selenium (Se) deficiency is associated with nutritional myopathy, known as white muscle disease (WMD), in horses. However, correlations between Se deficiency and clinical findings, such as hematologic biochemical values and pathological features, have not been evaluated in captive plains zebras. The purpose of the present study was to investigate the clinical and pathologic features that may be caused by a Se deficiency in the captive plains zebra. Clinical findings, feed analyses, hematologic biochemical analyses, response to treatment, and pathologic examination were assessed in six affected plains zebras. The dietary concentration of Se in feed was also tested. Sudden death occurred in two cases during the first day of the onset of symptoms. Two zebras died at 4 days and two zebras survived after treatment. The clinical signs in affected animals were characterized by general weakness, astasia, and abnormal postural positions. The Se concentration in hay from the breeding stable was low, based on the reference value. Glutathione peroxidase (GSH-Px) activity was lower compared with the equine reference value. Multiple areas of subcutaneous steatitis and pale skeletal muscle and myocardium were revealed at gross necropsy. Degeneration and necrosis of myocardial and skeletal muscles, as well as congestion of the liver, lung, and kidney were found via histopathological examination. No suspected bacterial infections were found. Feed analyses, response to treatment, serum GSH-Px activity, and pathological features suggest that Se deficiency may have caused the disease in the six affected captive plains zebra. © 2016 Springer Science+Business Media New York
