Avian malaria is a worldwide distributed, vector-born disease of birds caused by parasites of the order Haemosporida. There is a lack of knowledge about the presence and pathogenetic role of Haemosporida in Psittacidae. Here we report a case of avian malaria infection in lovebirds (), with the genetic characterization of the species involved. The birds were hosted in a zoo located in Italy, where avian malaria cases in African penguins () were already reported. Animals ( = 11) were submitted for necropsy after sudden death and were subjected to further analyses including histopathology, bacteriology, and PCR for the research of haemosporidians. Clinical history, gross lesions and histopathological observation of schizonts, together with positive PCR results for spp., demonstrated that avian malaria was the cause of death for one animal and the possible cause of death for the other nine. The sequences obtained were compared using BLAST and analyzed for similarity to sequences available at the MalAvi database. Genetic analyses demonstrated a 100% nucleotide identity to LINN1 for all the obtained sequences. To our knowledge, this is the first report describing avian malaria in lovebirds.
禽疟是一种由血孢子虫目寄生虫引起的、在全球范围内传播的鸟类媒介传播疾病。目前对于鹦鹉科鸟类中血孢子虫的存在情况及其致病作用了解不足。在此,我们报告一例情侣鹦鹉的禽疟感染病例,并对所涉及的物种进行了基因特征分析。这些鸟类饲养在意大利的一家动物园,该动物园此前已报告过非洲企鹅的禽疟病例。11只动物在突然死亡后接受了尸检,并进行了包括组织病理学、细菌学以及血孢子虫PCR检测等进一步分析。临床病史、大体病变、裂殖体的组织病理学观察以及血孢子虫属物种的PCR阳性结果表明,禽疟是其中一只动物的死亡原因,也是另外九只动物可能的死亡原因。使用BLAST对获得的序列进行比较,并分析其与MalAvi数据库中现有序列的相似性。基因分析表明,所有获得的序列与LINN1血孢子虫的核苷酸同一性为100%。据我们所知,这是首例描述情侣鹦鹉禽疟的报告。
