It is important to provide a baseline of fungal composition in the captive wildlife environment to better understand their role in overall wildlife health. The objectives were to identify species of fungi existing within wildlife animal enclosures and their environment at the National Wildlife Rescue Centre (NWRC) and the National Zoo, Malaysia and to describe their medical and veterinary importance. Samples of air, wall or floor swab, enrichment swab and soil were taken from the animal enclosures, exercise yard and enrichments at NWRC and National Zoo respectively. All samples including those pre-treated samples were plated onto Sabouraud's Dextrose Agar (SDA). Numerous fungi were grown on all sampling SDA plates regardless by either single or multiple growth. Samples of air in both NWRC and National Zoo had the highest growth of Penicillium spp. with a prevalence of 31.2% and 83.7% respectively. Samples of swab from the wall, floor and enrichments were predominantly by Candida spp. (42.6%) in NWRC and Penicillium spp. (41.6%) in the National Zoo. Prevalence of multiple fungi isolated from the soil samples in NWRC were 57.9% and yeast species was the most common in National Zoo with a prevalence of 88.9%. Overall, 29 and 8 isolates were found in both samples from the NWRC and National Zoo with a predominant species of potential zoonotic fungi have been identified in both premises. The expected fungus Aspergillus spp. was not isolated in all samples in NWRC. Prevalent fungal species found in this study are known to cause disease in animals and humans as primary pathogen and also as opportunistic pathogens that may also cause infection. Thus, health safety precautions should be considered particularly in dealing with conservation of endangered wildlife species, along with personnel and public involvements.
为了更好地了解真菌在野生动物整体健康中的作用,提供圈养野生动物环境中真菌组成的基线非常重要。本研究的目的是在马来西亚国家野生动物救援中心(NWRC)和国家动物园,确定野生动物围栏内及其环境中存在的真菌种类,并描述其医学和兽医重要性。从 NWRC 和国家动物园的动物围栏、运动场地和丰容中分别采集空气、墙壁或地板拭子、富集拭子和土壤样本。所有样本,包括预处理样本,均接种于沙氏葡萄糖琼脂(SDA)平板上。无论单一或多种生长方式,所有采样 SDA 平板上均长出了大量真菌。NWRC 和国家动物园的空气样本中,Penicillium spp.的生长最为普遍,分别为 31.2%和 83.7%。NWRC 中墙壁、地板和丰容的拭子样本主要为 Candida spp.(42.6%),而国家动物园中则为 Penicillium spp.(41.6%)。NWRC 土壤样本中分离出的多种真菌的患病率为 57.9%,酵母种类在国家动物园最为常见,患病率为 88.9%。NWRC 和国家动物园的样本中均发现了 29 株和 8 株分离株,其中主要的潜在人畜共患病真菌已在两个场所被鉴定出来。在 NWRC 的所有样本中均未分离出预期的真菌 Aspergillus spp.。本研究中发现的流行真菌种类已知会导致动物和人类患病,作为原发性病原体和机会性病原体,也可能引起感染。因此,应考虑采取健康安全预防措施,特别是在处理濒危野生动物物种的保护工作时,需要考虑人员和公众的参与。
