Abstract
Acuariidae nematodes are normally found in the digestive tract of aquatic birds, including Procellariiformes. Were examined Calonectris borealis (n = 4), Diomedea exulans (n = 1), Macronectes giganteus (n = 8), Thalassarche chlororhynchos (n = 5), Thalassarche melanophrys (n = 15), Procellaria aequinoctialis (n = 4), Puffinus gravis (n = 2) and Puffinus puffinus (n = 6), collected on the southern coast of RS, Brazil. A total of 16 birds (35.5%) were parasitized by two species of Acuariidae. Stegophorus diomedeae and Seuratia shipleyi were identified, with prevalences of 26.1% and 21.7%, respectively. Few studies on nematodes in Procellariiformes have been conducted. Here, the acuariids Seuratia shipleyi in Calonectris borealis and Procellaria aequinoctialis and Stegophorus diomedeae in Diomedea exulans, Procellaria aequinoctialis and Thalassarche chlororhynchos were reported for the first time.
Highlights
Acuariidae include midsized nematodes that inhabit the upper digestive tract of aquatic birds (Procellariiformes, Pelecaniformes, Ciconiiformes, Anseriformes, Charadriiformes and Coraciiformes), a few are associated with terrestrial birds such as Falconiformes, Galliformes and Passeriformes (ANDERSON, 2000).The species of this subfamily are characterized by the presence of cephalic cords as fixation structures (CHABAUD, 2009).Over the life cycle of acuariids, it has been observed that larvae in the infective stage are encapsulated in the intestine or mesentery of paratenic hosts to reach the final host
The acuariids Seuratia shipleyi in Calonectris borealis and Procellaria aequinoctialis and Stegophorus diomedeae in Diomedea exulans, Procellaria aequinoctialis and Thalassarche chlororhynchos were reported for the first time
Considering the ecological importance of these birds, the conservation condition of these species and the lack of information about their biology and helminth fauna, the aim of the present study was to report on occurrences of the acuariid nematodes Stegophorus diomedeae and Seuratia shipleyi as parasites of Procellariiformes on the southern coast of Rio Grande do Sul, and the infection rates in these birds

Acuariidae include midsized nematodes that inhabit the upper digestive tract of aquatic birds (Procellariiformes, Pelecaniformes, Ciconiiformes, Anseriformes, Charadriiformes and Coraciiformes), a few are associated with terrestrial birds such as Falconiformes, Galliformes and Passeriformes (ANDERSON, 2000). The species of this subfamily are characterized by the presence of cephalic cords as fixation structures (CHABAUD, 2009). Some esophageal parasites develop entirely in the esophagus, while others reach.
