Biting lice were collected (mostly in Poland) from 15 species of Charadriiformes (Charadriidae, Scolopacidae, Laridae and Alcidae). We tried to determine the frequency of occurrence of particular species of Mallophaga. Quantitative and qualitative analysis of co-occurrence of external parasites (Mallophaga and some Astigmata) was also carried out. We stated that inter-species competition is not significant in shaping the fauna of external parasites of Charadriiformes.
Mycological studies covered two species of Charadriiformes birds: Dunlin - Calidris alpina (41 individuals) and Ringed plover - Charadrius hiaticula (8 individuals). Swabs were collected from their beaks cavity and cloacae. Fungi (38 strains) were isolated from 29 birds (59.18% of the investigated). The most abundant were the yeast-like fungi (Candida, Cryptococcus, Rhodotorula), substantially dominated by Candida. albicans, which constituted 42.11% of all the fungi obtained. The fungi of the Aspergillus and Cryptococcus genera were found considerably less frequently (23.68% and 15.79%, respectively). The fungi isolated from beaks (19 birds) can be acknowledged as commensals (although parasitism cannot be excluded), whereas the fungi from cloacae (5 birds) may indicate mycosis of the gastrointestinal tract. As all of these fungi are potentially pathogenic to humans and animals, the examined birds were found to be an important link in the epidemiological chain of mycoses, associated with water reservoirs or infected birds.
Syringoplutarchusia, a new genus of the syringicolous feather mite family Syringobiidae (Pterolichoidea), is described based on a single new species, S. nordmanni sp. nov., collected from the feather quills of a museum specimen of the Black-winged Pratincole Glareola nordmanni Fischer, 1842 (Glareolidae). Absence of adanal discs and complete reduction of setae d and e on tarsi IV in males of the new genus is unique in this family. The highly elongated body shape of both sexes is most similar to the genera Plutarchusia Oudemans, 1904 and Paidoplutarchusia Dabert, 2003 but strong sclerotization of coxal fields and hypertrophied posterior legs with variously shaped apophyses resemble more advanced syringobiid mites, e.g. Syringobia Trouessart et Neumann, 1888. Syringoplutarchusia represents the first syringobiid from this host family. The taxonomic status of the new taxon is discussed.
During a re-assessment of tapeworm collections from wild birds in Slovakia, two Anomotaenia spp. were recovered from the intestine of the little ringed plover Charadrius dubius Scop., 1786. One of them is described as Anomotaenia barusi sp. nov. The new taxon is distinguished from related congeneric species by the different shape and size of the rostellar hooks, the number of testes and the morphology of male and female reproductive organs. The other species was identified as Anomotaenia alata Spassky et Konovalov, 1969. The validity of this species has formerly been questioned because of its striking morphological similarity to the type-species of the genus, A. microrhyncha (Krabbe, 1869), described from the same host, Philomachus pugnax (L.). Present data revealed differences in the number and measurements of the rostellar hooks, the size of the cirrus-sac, the armament of the cirrus and the presence or absence of setae at the polar ends of the inner egg envelope, which supported the validity of A. alata. The finding of A. alata in C. dubius from Slovakia represents a new host and geographical record.
