the lungworm, halocercus spp. (nematoda: pseudaliidae) in cetaceans from california.	three cetaceans from monterey bay, california (usa), were infected with lung nematodes. a beaked whale calf, mesoplodon sp. was infected with adult halocercus sp. this represents a new host record for this nematode. the lungs of a northern right whale dolphin calf, lissodelphis borealis, contained an unidentified nematode similar in size to halocercus sp. the presence of phyllobothrium delphini-type cestode larvae in its blubber is evidence that the calf was feeding on invertebrates. a pregnant ...	1993	8355360
tetraphyllidean cysticerci in the peritoneal cavity of the common dolphin.	cysticerci of the cestodes monorygma grimaldii and phyllobothrium delphini were encountered during necropsy of an adult common dolphin (delphinus delphis) found dead on the southeastern coast of australia. monorygma grimaldii cysticerci were found within highly organized retroperitoneal cysts, whereas p. delphini cysticerci in the subcutaneous blubber did not occupy specialized structures. there was a localized lymphoplasmacytic host response to the presence of cysticerci of both species, but m. ...	1997	9391979
macroparasites in cetaceans stranded on the northwestern spanish atlantic coast.	an extensive parasitological survey was carried out during autopsy of 80 cetaceans representing 8 species within 4 families (delphinus delphis, stenella coeruleoalba, tursiops truncatus, grampus griseus, globicephala melas, kogia breviceps, phocoena phocoena and megaptera novaeangliae) collected on the northwestern spanish atlantic coast from february 1991 to october 1996. two species of tetraphyllidean cestodes (phyllobothrium delphini and monorygma grimaldii), 2 ascaridoid nematodes (anisakis ...	1998	9676247
histopathological and immunohistochemical studies on cetaceans found stranded on the coast of italy between 1990 and 1997.	detailed histopathological and immunohistochemical studies were carried out on 24 cetaceans, 17 of which were striped dolphins (stenella coeruleoalba), four bottlenose dolphins (tursiops truncatus) and three risso's dolphins (grampus griseus), all found stranded on the italian coast between 1990 and 1997. the most frequently detected lesions were chronic pneumonia (73.7% of the examined lungs), focal chronic pancreatitis (71.4%), non-purulent encephalitis (50%), chronic hepatitis (42.1%), and ch ...	2000	10842462
morphological and molecular characterization of tetraphyllidean merocercoids (platyhelminthes: cestoda) of striped dolphins (stenella coeruleoalba) from the western mediterranean.	two types of tetraphyllidean merocercoids, phyllobothrium delphini and monorygma grimaldii, are well known from most cetaceans world-wide. the role of cetaceans in the life-cycle of these merocercoids is unclear because their specific identity is as yet unknown. the problem is compounded by poor descriptions of both merocercoids. we used light and scanning electron microscopy, and histological techniques to provide a thorough description of merocercoids collected from 11 striped dolphins, stenel ...	2005	15830821
tetraphyllidean plerocercoids from western mediterranean cetaceans and other marine mammals around the world: a comprehensive morphological analysis.	tetraphyllidean plerocercoids have occasionally been reported in marine mammals, but they have rarely been described in detail, and the ecological significance of these infections is unclear. we described plerocercoids collected from the mucosa of the terminal colon and rectum, the anal crypts, and the hepatopancreatic ducts of 7 striped dolphins stenella coeruleoalba, 1 cuvier's beaked whale ziphius cavirostris, and 3 risso's dolphins grampus griseus from the spanish mediterranean. we also exam ...	2005	15856877
microtriches of tetraphyllidean metacestodes from western mediterranean striped dolphins (stenella coeruleoalba).	the tegumental structures of two types of tetraphyllidean plerocercoids and two types of merocercoids (phyllobothrium delphini and monorygma grimaldii) from mediterranean striped dolphins, stenella coeruleoalba, are described for the first time using scanning electron microscopy. the tegument of all of the specimens was fully covered with microtriches. four basic types were found: filitriches, blade-like spinitriches of different sizes and shapes, cone-shaped spinitriches (with two parallel smal ...	2005	15959909
insight into the role of cetaceans in the life cycle of the tetraphyllideans (platyhelminthes: cestoda).	four types of tetraphyllidean larvae infect cetaceans worldwide: two plerocercoids differing in size, 'small' (sp) and 'large' (lp), and two merocercoids referred to as phyllobothrium delphini and monorygma grimaldii. the latter merocercoid larvae parasitize marine mammals exclusively and exhibit a specialised cystic structure. adult stages are unknown for any of the larvae and thus the role of cetaceans in the life cycle of these species has been a long-standing problem. the sp and lp forms are ...	2007	17161403
parasites in stranded cetaceans of patagonia.	there is an increasing interest in parasites of marine mammals of argentina. here, we examined several poorly known cetaceans, i.e., 2 spectacled porpoises and 1 burmeister's porpoise (phocoenidae), and 1 gray's beaked whale and 1 cuvier's beaked whale (ziphidae); we also updated the parasite information for 1 sperm whale (physeteridae). these hosts strand only occasionally. we found anisakis simplex s.l. in 2 spectacled porpoises and the burmeister's porpoise, and recorded its distribution amon ...	2008	18576713
additional records of metazoan parasites from caribbean marine mammals, including genetically identified anisakid nematodes.	studies of marine mammal parasites in the caribbean are scarce. an assessment for marine mammal endo- and ectoparasites from puerto rico and the virgin islands, but extending to other areas of the caribbean, was conducted between 1989 and 1994. the present study complements the latter and enhances identification of anisakid nematodes using molecular markers. parasites were collected from 59 carcasses of stranded cetaceans and manatees from 1994 to 2006, including globicephala macrorhynchus, kogi ...	2009	19582477
metazoan parasites of cetaceans off the northeastern coast of brazil.	this study represents the first survey of the parasitic fauna of cetaceans off the northeastern coast of brazil. parasites were collected from 82 animals rescued from the states of ceará to bahia, including the archipelago of fernando de noronha. a total of 14 species of cetaceans were evaluated: sotalia guianensis, stenella sp., stenella clymene, stenella longirostris, stenella coeruleoalba, stenella frontalis, megaptera novaeangliae, peponocephala electra, steno bredanensis, kogia breviceps, k ...	2010	20638793
parasites of cetaceans stranded on the pacific coast of costa rica.	information regarding parasitic fauna of cetaceans from costa rica is provided for the first time. a total of 25 stranded dolphins and whales were examined between 2001 and 2009, including striped dolphin (stenella coeruleoalba) (n=19), pantropical spotted dolphin (s. attenuata) (n=2), spinner dolphin (s. longirostris) (n=1), bottlenose dolphin (tursiops truncatus) (n=1), dwarf sperm whale (kogia sima) (n=1) and cuvier's beaked whale (ziphius cavirostris) (n=1). pathological findings associated ...	2011	21665367
metazoan parasites from odontocetes off new zealand: new records.	information about the parasite fauna of spectacled porpoises and cetaceans from new zealand waters in general is scarce. this study takes advantage of material archived in collections of the otago museum in dunedin and massey university in auckland, sampled from cetacean species found stranded along the new zealand coastline between 2007 and 2014. parasites from seven species of cetaceans (spectacled porpoise, phocoena dioptrica (n = 2 individuals examined); pygmy sperm whale (n = 1); long-finne ...	2017	28799088
