The aim of the present work was to investigate the prevalence and species of intestinal microsporidiosis among animals in Giza, Egypt.
A total of 869 animal fecal samples were collected from domesticated animals (dogs, cats, rabbits, cattle, buffaloes, sheep, goats, donkeys and pigs) living in Giza, Egypt. Spores of microsporidia were concentrated from collected samples by centrifugation and finally stained with modified trichrome (MT) stain to detect microsporidial spores. Microsporidial spores in microscopically-positive samples were molecularly confirmed and identified using species-specific primers.
Spores of microsporidia were microscopically detected in 17.0% of the examined animal fecal samples. The highest and lowest rates of infection with intestinal microsporidia were recorded in dogs (33.3%) and buffaloes (6.9%), respectively. Molecularly, the obtained microsporidial spores were classified as and . Dual infection with both identified species was observed in fecal samples from buffalo, rabbit, goat, cat, pig and dog.
Domestic animals may play a role in dissemination of intestinal microsporidiosis in the environment. Examined animals were infected with in a higher percentage than .
本研究旨在调查埃及吉萨地区动物肠道微孢子虫病的患病率及种类。
从埃及吉萨地区的家养动物(狗、猫、兔子、牛、水牛、绵羊、山羊、驴和猪)中总共采集了869份动物粪便样本。通过离心从采集的样本中浓缩微孢子虫的孢子,最后用改良三色(MT)染色法染色以检测微孢子虫孢子。使用种特异性引物对显微镜检查呈阳性的样本中的微孢子虫孢子进行分子确认和鉴定。
在17.0%的被检查动物粪便样本中显微镜检测到微孢子虫孢子。肠道微孢子虫感染率最高和最低的分别是狗(33.3%)和水牛(6.9%)。在分子水平上,获得的微孢子虫孢子被分类为 和 。在水牛、兔子、山羊、猫、猪和狗的粪便样本中观察到两种已鉴定种类的双重感染。
家养动物可能在环境中肠道微孢子虫病的传播中起作用。被检查动物感染 的比例高于感染 的比例。
