Microtetrameres cloacitectus in Eurasian buzzard (Buteo buteo): pathology, phylogenetics, and seasonality.

ABSTRACT: Microtetrameres cloacitectus is a nematode of the family Tetrameridae Travassos, 1914, parasitising the proventricular glands of diurnal raptors. First described by Oschmarin (1956) from the Eurasian buzzard (Buteo buteo) in Primorsky Krai, Russia, it has since been reported in several raptor species. Between 2017 and 2024, 88 deceased Eurasian buzzards were collected from various regions in Romania. For each specimen, GPS coordinates, sex, and age were recorded, and full parasitological necropsies were performed. One individual (over three-year-old male found as roadkill in Tureni, Cluj County, Northwestern Romania) had Microtetrameres-like nematodes; a section of its proventriculus was preserved in 10% formalin for histopathological examination. In the remaining positive cases, nematodes
