The ixodid tick Ixodes granulosus Supino 1897 was found infesting Rattus rattus in Semakau island, one of the small offshore islands fringing Singapore to the south. None of the examined R. rattus from the other islands fringing Singapore, or from Singapore island were found infested. Ixodes granulatus occurs, however, on Singapore island on Rattus annandalei, resident of undisturbed forested habitats. We speculate that invading black rats in Semakau replaced autochthonous sylvatic rodent population and contracted their associate tick population.
Résumé
L’infestation de Rattus rattus par la tique Ixodes granulosus Supino 1897 a été mise en évidence dans la petite île de Semakau au sud de Singapour. Aucun des R. rattus examinés dans l’île de Singapour ou dans les autres îles de la région n’a été trouvé infesté. Cependant, Ixodes granulatus est présent chez Rattus annandalei dans les forêts de l’île de Singapour. On suppose que le rat noir, en envahissant l’île de Semakau, a remplacé le rongeur sylvatique autochtone et a contracté sa tique.
