“…In general, the pathological findings presented here agree with descriptions made in domestic and wild birds (Nath & Pande, 1963; Bishop & Threlfall, 1974; Taraschewski & Hofmann, 1991), mammals (Nelson & Nickol, 1986; Richardson & Barnawell, 1995) and fish (de Buron & Nickol, 1994; Sanil et al 2011) infected with different species of acanthocephalans. Fibrous nodules similar to those observed in Olrog's gull chicks have been reported in other avian species, such as Melanerpes carolinus (Picidae) infected by Mediorhynchus centurorum (Nickol, 1969), domestic ducks infected by Polymorphus minutus and Filicollis anatis (Nicholas & Hynes, 1958; Taraschewski & Hofmann, 1991), and Somateria mollissima (Anatidae) infected by Profilicollis botulus (Bishop & Threlfall, 1974). Also, the composition of inflammatory cells surrounding the parasites and comprising the granulomas resembles those described by Gonzales-Viera et al (2009) in Leucocephalus modestus (Laridae) infected by Profilicollis altmani , as well as by Taraschewski & Hofmann (1991) in domestic ducks infected by Filicollis anatis .…”

Acanthocephalans can be pathogenic helminths of marine birds. Every year during the breeding season, there is variable mortality among prefledged chicks from the largest known Olrog's gull (Larus atlanticus) colony. Mortality has been associated with infection by the acanthocephalan Profilicollis chasmagnathi. Our aim was to study the role of chicks' size as a risk factor for intensity of infection and severe pathology, and to expand upon previous pathological findings reported in acanthocephalan-infected chicks. Size of the chick was associated with intensity of infection and number of intestinal perforations, which increased by 6.9% and 4.1%, respectively, for each millimetre increment in chick size. Infection was associated with inflammatory enteritis and granulomatous peritonitis. Complete intestinal perforations were observed in 85% and 97.3% of the studied chicks in 2005 and 2006, respectively, and they were observed very early during the post-hatching period. Our results show: (1) the presence of advanced pathology associated with acanthocephalan infections in chicks, beginning very early in the post-hatching period; and (2) significant increases in the intensity of infection and the associated pathology as a function of size of chicks, in dead chicks during this period.

PurposeThe molecular profile of specimens of Mediorhynchus gallinarum (Bhalero, 1937) collected from chickens, Gallus gallus L. in Indonesia was analysed. The aim of this study was to assess the phylogenetic position of species of Mediorhynchus within the order Giganthorhynchida. Methods We used one mitochondrial gene (cytochrome oxidase 1) and one nuclear gene (18S ribosomal RNA) to infer phylogenetic relationships of class Archiacanthocephala. ResultsThe COI and 18S rDNA genes sequences showed that M. gallinarum had low genetic variation and that this species is sister to Mediorhynchus africanus Amin, Evans, Heckmann, El-Naggar, 2013. The phylogenetic relationships of the Class Archiacanthocephala showed that it is not resolved but, however, were mostly congruent using both genes. A review of host-parasite life cycles and geographic distributions of Archiacanthocephala indicates that mainly small mammals and birds are definitive hosts, while termites, cockroaches, and millipedes are intermediate hosts. Conclusions While the intermediate hosts have wide geographic distributions, the narrow distribution of the definitive hosts limit the access of archiacanthocephalans to a wider range of prospective hosts. Additional analyses, to increase taxonomic and character sampling will improve the development of a robust phylogeny and provide more stable classification. The results presented here contribute to better understanding of the ecological and evolutionary relationships that allow the hostparasite co-existence within the class Archiacanthocephala.

“…Although the observed species richness was 12, the number of species per bird was extremely low; 40 (54%) of the 74 red-bellied woodpeckers had no helminths, 27 had 1 species of helminth, and 7 had 2 species. The helminths with the highest prevalences were Aproctella stoddardi Cram, 1931 (11%), M. centurorum Nickol, 1969 (11%), Pseudaprocta samueli Bartlett and Anderson, 1986 (9%), and Procyrnea pileata (Walton, 1928) (8%). There were no significant differences in prevalences or intensities between host genders for any of the helminths analyzed at either ARD or WRD (P = 0.548-1.000).…”

“…The low prevalences and intensities of the helminth fauna in this study may be related to the fact that all these birds nested, foraged, and were collected in similar firemanipulated mature pine habitats. Nickol (1969) reported that 23% (12/53) of the red-bellied woodpeckers he sampled in Louisiana were positive for M. centurorum. He also reported intensities ranging from 1 to 13, a mode of 2, with only 2 birds having more than 3 M. centurorum.…”

Seventy-four red-bellied woodpeckers (Melanerpes carolinus) from the Apalachicola National Forest (30 degrees 10'N, 84 degrees 40'W) in northwest Florida were examined for helminths. The most prevalent parasites were the nematode Aproctella stoddardi (11%) and the acanthocephalan Mediorhynchus centurorum (11%). New host records include Pseudaprocta samueli, A. stoddardi, Tridentocapillaria tridens, Diplotriaena americana, Dispharynx nasuta, Procyrnea pileata, Orthoskrjabinia rostellata, and Brachylaima fuscatum. The helminth fauna was characterized by low prevalences and intensities of infection and low numbers of species per bird (1.2). The frequency of prescribed burning and habitat understory flora composition did not influence the prevalences or intensities of helminths in red-bellied woodpeckers collected from 2 similar but differently managed sites within the forest.
