Abstract：
Cyclospora cayetanensis, a recently described coccidian parasite causes severe gastroenteric disease worldwide. Limited studies are found on the incidence of C. cayetanensis infection from India; hence remains largely unknown. To date, no case of cyclosporiasis from eastern India has been reported. In this study, we described an incidental case of C. cayetanensis in a 30 years old Bengali female patient with no travel history from eastern India. In June 2022, the patient presented with a history of diarrhoea persisting for more than two months with continuous passage foul smelling stools for which she took multiple antibiotics that were ineffective. There were no Salmonella, Shigella, or Vibrio-like organisms in the patient\'s faecal sample, and Toxin A/B of Clostridium difficile was also not detected by ELISA. The patient was HIV-negative. Finally, UV autofluorescence and DNA-based diagnosis confirmed the presence of C. cayetanensis, and the treatment with a combination of appropriate antibiotics was successful. This case report could raise awareness about C. cayetanensis associated diarrhoeal cases in India.
摘要：
cayetanensis环孢菌,最近描述的一种球虫寄生虫在世界范围内引起严重的胃肠道疾病。对来自印度的C.cayetanensis感染的发生率进行了有限的研究；因此仍然未知。迄今为止,没有来自印度东部的环孢菌素病例的报道。在这项研究中,我们描述了一名30岁的孟加拉女性患者中的C.cayetanensis偶然病例，该患者没有来自印度东部的旅行史。2022年6月，患者出现腹泻史，持续超过两个月，并持续有恶臭的粪便，她服用了多种无效的抗生素。没有沙门氏菌,志贺氏菌,或患者粪便样本中的弧菌样生物，ELISA也未检测到艰难梭菌的毒素A/B。患者为HIV阴性。最后,紫外线自发荧光和基于DNA的诊断证实了C.cayetanensis的存在，联合使用适当的抗生素治疗是成功的。该病例报告可以提高对印度cayetanensis相关腹泻病例的认识。
