This study reports the case of a Manx shearwater (Puffinus puffinus) that died from avian malaria while under care at a rehabilitation center in Espírito Santo, Brazil. The bird was rescued on October 2018, and remained under care until it died suddenly on January 2019. A blood smear produced 8 days before death was negative for parasites, whereas a blood smear produced post-mortem revealed a high parasitemia by a parasite resembling Plasmodium cathemerium. The sequence of a 412 bp segment of the cyt-b gene was identical to that of lineage PADOM09, and phylogenetic analysis corroborated that this parasite was closely-related to known lineages of P. cathemerium. The acuteness and severity of the infection documented in this case suggest that seabirds of the order Procellariiformes might be highly susceptible to Plasmodium infections, raising the concern that avian malaria may present a significant threat to their conservation.

这项研究报告了在巴西圣埃斯皮里图（EspíritoSanto）的康复中心接受护理时，死于禽类疟疾的曼克斯x水（Puffinus puffinus）。该鸟于2018年10月获救，一直受到护理，直到2019年1月突然死亡。在死亡前8天进行了血液涂片检查，对寄生虫呈阴性，而验尸后进行的血液涂片检查则显示出高寄生虫病，类似于疟原虫。澡堂。cyt- b基因一个412 bp片段的序列与谱系PADOM09的序列相同，系统发育分析证实该寄生虫与已知的P. cathemerium谱系密切相关。在这种情况下记录的感染的严重性和严重性表明，Procellariiformes目海鸟可能高度易受疟原虫感染，这引起了人们的关注，即禽类疟疾可能对其保护构成重大威胁。
