Abstract

The amoeboflagellate genus Naegleria includes a few species that are virulent in experimental animals. One of these species, Naegleria italica, has been isolated from the environment only in Italy and Australia. I report here the isolation of a strain of N. italica from a water sample collected in Peru. This broadens the occurrence of this species to encompass three different continents. This new N. italica isolate from Peru has the same ITS1, 5.8S rDNA and ITS2 sequence as that of the type strain from Italy and the isolate from Australia. From the same water body in Peru a Naegleria strain was isolated that differs from N. italica by only one additional base pair in the ITS2 sequence. The maximum growth temperature tolerated by this particular isolate is 40 degrees C, which is different from that of N. italica, which is 42 degrees C.

摘要

阿米巴鞭毛虫属的耐格里属包括一些在实验动物中具有致病性的物种。其中一个物种，意大利耐格里变形虫，仅在意大利和澳大利亚的环境中被分离出来。我在此报告从秘鲁采集的水样中分离出一株意大利耐格里变形虫。这将该物种的分布范围扩大到了三个不同的大陆。从秘鲁分离出的这株新的意大利耐格里变形虫与来自意大利的模式菌株以及来自澳大利亚的分离株具有相同的ITS1、5.8S rDNA和ITS2序列。从秘鲁的同一水体中分离出了一株耐格里变形虫菌株，其ITS2序列与意大利耐格里变形虫仅相差一个额外的碱基对。该特定分离株所能耐受的最高生长温度为40摄氏度，这与意大利耐格里变形虫的42摄氏度不同。
