“…In the crop, heterophils were also reported next to the nematode Eucoleus anullatus in turkeys (Pinto et al, 2008). However, Capillaria anatis did not induce any pathology in turkey tissue (Pinto et al, 2008) and no inflammatory infiltrate was seen in the ventriculus of sparrows infected with the nematode Acuaria skrjabini (Sato et al, 2005). Thus, depending on the host and the nematode, heterophilic infiltration, granuloma formation or no reaction have been described.…”

The carcasses of ten great cormorants (Phalacrocorax carbo) found in one colony in the province of Vojvodina were necropsied and examined for parasites. The study aimed to identify helminths and histopathologically evaluate the associated tissue damage. Numerous nematodes were observed, either free in the the lumen of the ventriculus or deeply embedded in the ventricular mucosa of all the cormorants examined. The collected parasite samples were morphologically identified as Contracaecum rudolphii sensu lato. The main pathological findings included a thickening of the ventricular wall, while histopathology revealed a mild inflammatory infiltrate in the adjacent tissue and a connective tissue capsule around the parasite. Given that the parasites in this bird species still need to be thoroughly studied in our country, particularly the pathomorphological changes they cause, this study represents the first attempt to obtain a comprehensive understanding picture of the nematode infection and the pathological changes resulting from the presence of this parasite.

Acuaria subula (Dujardin, 1845) is redescribed by light microcopy (LM) and scanning electron microscopy (SEM) on the basis of specimens from its type host, Erithacus rubecula (Passeriformes, Muscicapidae), from Curonian Spit (Kaliningradskaya Oblast', Russia) and Bulgaria. Acuaria skrjabini (Ozerskaya, 1926) is redescribed by LM and SEM on the basis of specimens from Passer domesticus (type host) and P. hispaniolensis (Passeriformes, Passeridae) from Bulgaria. Contrary to previous opinions recognizing A. skrjabini as a junior synonym of A. subula, the present study confirms that they are distinct species. They can be distinguished on the basis of the ratio between the length of cordons and the body length, the ratio between the length of muscular oesophagus and glandular oesophagus, and the ratio between the total length of oesophagus and the body length. In addition, the plates forming the cordons in these two species exhibit different morphological characters. Another difference between these two species is associated with the particular irregular mosaic ornamentation of the cuticle on the ventral and lateral sides of body around the region of vulva of A. subula and its absence in A. skrjabini. Data on their host and geographical ranges are surveyed. The type series of Acuaria buttnerae Chabaud et Petter, 1961, described as a parasite of Calandrella brachydactyla (Passeriformes, Alaudidae) in France, is re-examined; the latter species is recognized as a junior synonym of A. skrjabini (new synonymy).
