AI Article Synopsis
- Air sac nematodes, first described over 200 years ago with Filaria attenuata from falcons and owls, have had a complex classification history due to loss of original materials.
- Seurat (1915) redefined this species using specimens from falcons in Algeria, leading to the creation of a new species, Serratospiculum seurati, by Bain and Mawson in 1981 based on slight variations.
- Recent study of S. seurati through light and scanning electron microscopy on specimens from a Peregrine falcon in Pakistan revealed size measurements and spicule characteristics, confirming its presence in various falcon species.
Article Abstract
Air sac nematodes from birds are known for more than 200 years now and Filaria attenuata was the first described species from falcons, owl and corvid birds. The superficial description and the loss of the original material made F. attenuata a species inquirenda. Seurat (1915) redescribed the species with material from lanner falcon and pallid harrier from Algeria and based on this description Bain and Mawson, Rec S Aust Mus 18:265-28, (1981) created a new species, Serratospiculum seurati, by adding some, slightly divergent, measurements. The current paper is based on light and scanning electron microscopy of five male and 10 female S. seurati specimens from a Peregrine falcon that acquired the infection in Pakistan. The length of the slender male and female nematodes varied between 42-70 and 165-221 mm, respectively, spicules of unequal shape and length measured 292-325 and 638-785 μm. S. seurati was also found in Saker, Barbary and crossbreed falcons.

During two falcon seasons (2020/21 and 2021/22) we investigated Serratospiculum samples from 112 falcons and examined a total of 760 nematodes. Of the 112 falcons, there were 62 Saker (Falco cherrug), 15 Peregrine (Falco peregrinus), 11 Gyr (Falco rusticolus), 7 Lanner falcons (Falco biarmicus) and 17 hybrid falcons. In 47 samples the origin of the birds was not mentioned, 49 were from Mongolia, 6 from the UAE, 3 from the USA, 2 from Russia, 2 from the UK and one each from Kazakhstan, Uzbekistan and Germany.

The aim of this study was to describe parasitological, microbiological, and pathological findings associated with the isolation of Aspergillus species in 94 clinically diseased captive falcons from Dubai. Concomitant agents and/or diseases were identified in 64 cases, causing either single (n = 36) or multiple coinfections (n = 28). Diagnoses found more often in association with aspergillosis were chronic fatigue and immune dysfunction syndrome (CFIDS) (n = 29), Caryospora sp.
