Abstract

Stenurus globicephalae Baylis et Daubney, 1925 (Nematoda: Pseudaliidae)

Specificity of Stenurus (Metastrongyloidea: Pseudaliidae) infections in odontocetes stranded along the north-west Spanish coast

“…According to different authors, Pseudaliids located in the cranial sinuses and middle ear provoke minor hemorrhage, mild to moderate nonsuppurative chronic inflammation and thickening of the sinus mucosal lining, rarely purulent sinusitis ( Delyamure 1955 ; Measures 2001 ). However, Zylber et al (2002) detected the presence of abundant lungworms, identified as S. globicephalae in the cranial air sinuses of a false killer whale ( Pseudorca crassidens Owen, 1846) which revealed loss of osseous mass with the disappearance of the left zygomatic arch, and the left jaw had three osseous fenestrations in the region related to the organ of acoustic reception. These lesions supported the hypothesis of these authors that this infection was related to the stranding.…”

“…Nine species of Stenurus have been reported in odontocetes throughout the world ( Zylber et al, 2002 ). Most species are found in the middle ear, eustachian tube and cranial sinuses, while a few of them are found in bronchi and bronchioles ( Measures 2001 ).…”

Insights sobre um encalhe em massa de falsas orcas (Pseudorca Crassidens Owen, 1846)

“…: Leiper & Atkinson, 1914). Acute otitis is a possible cause of cetacean mass stranding (GERACI et al, 1987;KIJEWSKA et al, 2003;ZYLBER et al, 2002). The clinico-pathologic relevance of this finding is unclear in this mass-stranding event yet it could have played a role.…”
