“…Based on the corresponding 795-base pair fragment sent to GenBank from both studies, we determined using a LI-COR AlignIR Alignment Report that there was a 100.0% similarity with what the two studies consider Bolbophorus sp., a 99.8% similarity in B. damnificus and 97.0% similarity between the two. Overstreet et al (2002) The other catfish diplostomoid maturing in pelicans, Bursacetabulus pelecanus, to date has been seen in both P. erythrorhynchos and P. occidentalis in Mississippi and Louisiana in addition to the reports from Texas (Dronen et al 2003). Molecular work to show relationships among this and some of the other diplostomes will be reported by Charles Blend, presently at Texas A & M University, and colleagues (pers.…”

Abstract. Diplostomoid digenean metacercariae have caused widescale mortalities of channel catfish, Ictalurus punctatus (Rafinesque), at aquaculture farms in Louisiana, Mississippi and Arkansas, USA. Originally, based on a tentative diagnosis, the industry considered the primary harmful agent to be an introduced species from Europe, Bolbophorus confusus (Krause, 1914), frequently reported from the American white pelican, Pelecanus erythrorhynchos Gmelin. Our group has now shown, using ITS 1-2 plus three more-conservative gene fragments, that two sympatric species of Bolbophorus exist in the American white pelican. One, B. damnificus Overstreet et Curran, 2002, infects the musculature of catfish, and the other, probably not B. confusus, does not infect catfish. However, at least four other pathogenic diplostomoids and a clinostomoid infect the catfish, and they use at least four different snail hosts, including the planorbids Planorbella trivolvis (Say) and Gyraulus parvus (Say), the physid Physella gyrina (Say) and a lymnaeid. Two metacercariae, B. damnificus and Bursacetabulus pelecanus Dronen, Tehrany et Wardle, 1999, infect the catfish and mature in the pelican; two others, Austrodiplostomum compactum (Lutz, 1928) and Hysteromorpha cf. triloba (Rudolphi, 1819), mature in cormorants; one, Diplostomum sp., matures in seagulls and at least one, Clinostomum marginatum (Rudolphi, 1819), matures in herons, egrets and other wading birds. Consequently, management of catfish ponds relative to digenean infections requires considerable biological information on the fish, bird, and snail hosts as well as the parasites.

“…Of the 62, about 24 have not been reported from the brown pelican (e.g., Dyer et al 2002). Many are confined to both pelican species (e.g., Dronen et al 2003), but others infecting both pelicans also infect other birds. About 10, consisting of lice, mites, and helminths, infect the AWP only.…”

“…Even though few birds were examined critically by either Dronen et al (2003) or us and little can be determined from incomplete data on prevalence or intensity, we can surmise that the endohelminths from the AWPs from the Mississippi-Louisiana region had a greater richness than in the counterparts from the Galveston Bay, Texas, area. Ten endohelminths reported from six AWPs from Texas compared with 19, or at least 20 considering synonyms, from Mississippi/Louisiana and with 33 from Florida, where the sample size was much larger Spalding 2002, Kinsella et al 2004).…”

Metazoan symbionts, including parasites, infecting the American white pelican (AWP) Pelecanus erythrorhynchos comprise a list of 75 species, 7 of which are new host records. Several new geographic records are also presented, but generally these have a low value because of the migratory nature of the bird. Evidence suggests that some parasites, mostly flies and other arthropods but also nematodes and digeneans, produce detrimental behavioral or pathologic changes in the AWP. Some of the arthropods transmit microbial agents to the pelican. Two digeneans that have the AWP as a definitive host harm and even kill their catfish intermediate host, especially in aquaculture, and another causes abnormalities and mortality in amphibians. Some of the arthropods with low hostspecificity can potentially transmit harmful microbial agents to humans and domestic animals. A few avian bloodflukes, intestinal flukes, and nematodes can potentially cause "swimmers itch," gastroenteritis, and "anisakiasis," respectively, in humans. Because of the life cycles of some helminths, presence of those worms can provide an indication as to the dietary items of a specific pelican individual, where the individual has been, and how long it has been present in an area. Feather mites, lice, and diplostomoid digeneans serve as good parasites to indicate phylogenetic relationships among different pelican species as well as relationships among the Pelecanidae and other families such as the Sulidae.

“…Up to now, three species of parasite; C. multipapillatum, C. gibsoni and C. overstreeti have been detected from Pelecanus crispus. However, some other Contracaecum species have been reported from other genus of Pelicanidae 6,8 . Diagnosis of Contracaecum species from fisheating birds can be conducted by using morphological characteristics such as the length of the spicules, the morphology of the distal end of the spicule, and the bifurcation of the interlabial tip.…”

SummaryContracaecum genus (Ascaridida: Anisakidae) is a nematode parasite of the fish-eating birds throughout the world. A heavy infection of Contracaecum sp. was detected at the necropsy of a Dalmatian pelican (Pelecanus crispus) that had been referred to an animal hospital due to trauma and died before the initiation of any treatment. Intense parasitic infection was seen in the proventriculus and within the lumen of oesophagus to duodenum. This is the first case of intense adult Contracaecum sp. infection in a piscivorous bird in Turkey. Keywords: Contracaecum sp, Infection, Pelican, Turkey Tepeli Pelikanda (Pelecanus crispus) Contracaecum sp. (Ascaridida: Anisakidae) Enfeksiyonu Olgusu ÖzetContracaecum cinsi (Ascaridida: Anisakidae), dünyanın birçok bölgesindeki balık yiyen su kuşlarının nematod parazitidir. Hayvan hastanesine travma teşhisi ile getirilen ve herhangi bir tedaviye başlamadan ölen bir tepeli pelikanın (Pelecanus crispus) nekropsisinde yoğun miktarda Contracaecum sp. görülmüştür. Kuşun proventrikülüsünün bu parazitlerle dolu olduğu, hatta özefagusun son bölümüne ve duodenuma kadar uzandığı gözlenmiştir. Bu olgu parazitin yoğunluğu bakımından ilginç bulunmuş olup, Türkiye'de bir su kuşunda olgun Contracaecum sp. 'nin ilk bildirimidir.
