Eurasian griffon vultures (Gyps fulvus) are endangered scavenger birds. Haemosporidian parasites infect the blood cells and organs of many avian species globally, using blood-sucking insect vectors, and they negatively affect health of birds and subsequently wildlife biodiversity. Fifty-nine vultures were admitted to the Greek wildlife rehabilitation center “ANIMA” and included in this study. Blood samples were collected, and the microscopy of stained blood smears was performed. Moreover, DNA was extracted, samples were screened for Leucocytozoon, Haemoproteus, and Plasmodium spp. following nested PCR protocols, and positive samples were sequenced. The detected haemosporidians are reported for the first time in Eurasian griffon vultures globally. The overall prevalence was 11.9% (Leucocytozoon spp. 5.1%, Haemoproteus spp. 5.1%, Plasmodium spp. 3.4%); this further corroborates the statement that the vultures’ immunity protects them from blood parasites. Notably, new genetic lineages of Leucocytozoon (GYPFUL02), Haemoproteus (GYPFUL01), and Plasmodium (GYPFUL03) species were recorded for the first time. Furthermore, it was the first molecular isolation of Haemoproteus in Old World vultures and Haemoproteus brachiatus was isolated for the first time from a vulture species. Moreover, this demonstrates the first record of Parahaemoproteus genetic lineages in vultures. Results highlight the genetic diversity of haemosporidians in griffon vultures and the need for additional studies.

The most common causes of respiratory diseases in wild hedgehogs are the lungworms Crenosoma striatum and Capillaria aerophila, which can lead to life-threatening pneumonia. The aim of the current study was (A) to assess the prevalence of common lungworm infections in northern white-breasted hedgehogs (Erinaceus roumanicus) in Greece and (B) to identify an efficient and easy to administer treatment option. (A) Fifty-six hedgehogs were admitted to a Greek wildlife rehabilitation center and included in the present study. Fecal tests were performed using the flotation method (ZnSO₄ 33.2%) combined with the Baermann technique. In total, 49 hedgehogs excreted Crenosoma spp. larvae (87.5%), and 27 of them were also infected with Capillaria spp. (48.2%). One of them died, and the necropsy and lung histopathology confirmed the diagnosis of crenosomosis. (B) Fourteen animals with mixed infections were treated using NexGard^® Combo (esafoxolaner, eprinomectin, praziquantel) administered orally at a dose rate of 0.2 mL/kg body weight, once. On days 10 and 14 post-treatment, no parasitic elements were detected in the feces of the infected animals. All the animals had gained weight by day 14, and their biochemical parameters were normal. It was concluded that this combination given orally was safe and successful against hedgehog respiratory nematodes.
