PURPOSE
The present study aims to record the occurrence of a haemogregarine of the genus Dactylosoma in anurans in the eastern Brazilian Amazon.
METHODS
Specimens of Leptodactylus macrosternum, Rhinella major, and Rhinella marina were collected in the municipality of Santarém, west of the State of Pará, in Brazil. Parasitic forms identified as Dactylosoma sp. were recorded by light microscopy, with magnification of 400 and 1000 X.
RESULTS
Aspects about the morphology and morphometry of Dactylosoma sp. are presented. The mean intensity of infection was 200,000 parasites/mL in R. major and 50,000 parasites/mL in R. marina.
CONCLUSION
The present study expands the occurrence of parasites of the genus Dactylosoma in Brazil, presenting a new anuran host for this parasite in the Brazilian Amazon region.
目的
本研究旨在记录在巴西亚马逊东部的两栖动物中出现的一种血孢子虫属的血孢子虫。
方法
在巴西帕拉州西部的圣塔伦市收集了大趾蟾属的莱氏蟾和海蟾属的海蟾标本。通过光学显微镜，放大倍数为 400 和 1000 X，记录到被鉴定为血孢子虫属的寄生形式。
结果
呈现了血孢子虫属的形态和形态测量学的方面。在 R. major 中，平均感染强度为 200,000 个寄生虫/mL，在 R. marina 中为 50,000 个寄生虫/mL。
结论
本研究扩大了巴西血孢子虫属寄生虫的发生范围，为巴西亚马逊地区的这种寄生虫提供了一个新的两栖动物宿主。
