| the ecology of echinococcus multilocularis (cestoda: taeniidae) on st. lawrence island, alaska. ii. helminth populations in the definitive host. | the helminths of 1,579 arctic foxes from st. lawrence island were investigated by standard methods. the foxes, obtained mainly during the winter from fur trappers, harbored 22 species of helminths. four of those were trematodes, viz., maritrema afanassjewi belopol'skaia, 1952, orthosplanchnus pygmaeus iurakhno, 1967, plagiorchis elegans (rudolphi, 1802) and alaria marcianae (larue, 1917), each of which occurred in a single host. two species of cestodes, diphyllobothrium dendriticum (nitzsch, 182 ... | 1990 | 2080830 |
| transmammary transmission of mesocercariae of alaria marcianae (trematoda) in experimentally infected primates. | a lactating primate, callithrix jacchus, was infected experimentally with 600 mesocercariae of alaria marcianae 10 days after parturition to determine if she would transmit the mesocercariae to her offspring. her twin infants were examined 4 wk postinoculation and 16 mesocercariae were found in their tissues. the female was mated again and gave birth to a litter of triplets. she was not given additional mesocercariae. one infant died within hours of birth without suckling and was found negative ... | 1990 | 2254822 |
| transmission of ancylostoma caninum and alaria marcianae in coyotes (canis latrans). | one of seven female coyotes (canis latrans) captured in webb county, texas during september 1986 and confined and mated in holding facilities at millville, utah whelped the following spring. the maternal female (greater than 5-yr-old) and her five neonates were killed at 22 days postparturition. all were infected with adult ancylostoma caninum and were passing eggs in their feces. also, the neonates and maternal female were infected with immature and adult alaria marcianae, respectively. these f ... | 1988 | 3411716 |
| maternal transmission by alaria marcianae (trematoda) and the concept of amphiparatenesis. | the term amphiparatenic host was coined originally for hosts of alaria marcianae that as adults are paratenic hosts, but as juveniles serve as definitive hosts. in this study the concept of amphiparatenesis is placed in a theoretical context, maternal transmission shown to be the basic mechanism, and the concept extended to include toxocara canis, t. cati, t. pteropodis, neoascaris vitulorum, ancylostoma caninum, uncinaria lucasi, various species of strongyloides, pharyngostomoides procyonis, an ... | 1987 | 3572644 |

| tegumental changes of alaria marcianae (trematoda) during migration in the domestic cat. | mesocercariae of alaria marcianae were removed from snake paratenic hosts and fed to domestic cats. the cats were necropsied at specified intervals, the parasites recovered, and studied by sem. during the prepulmonary phase of migration in cats, mesocercariae recovered from the stomach wall, abdominal cavity, diaphragm, liver, and heart underwent no tegumental modification compared to those fixed immediately after removal from the paratenic host. the mesocercaria resembled the body of an enlarge ... | 1984 | 6470887 |
| pathway of mesocercariae of alaria marcianae (trematoda) through the mammary glands of lactating mice. | lactating mice were infected with mesocercariae of alaria marcianae to demonstrate more precisely how these parasites migrate within the mammary glands. the infected dam that first transmitted larvae to all of her young was necropsied and her mammary glands removed and sectioned serially. mesocercariae penetrated the dense connective tissue surrounding the lobules. within the stroma the larvae migrated along tracks of fat cells and were consistently found in pools of milk created from the destru ... | 1984 | 6491841 |
| population dynamics across selected habitat variables of the helminth community in coyotes, canis latrans, from south texas. | the effects of selected intrinsic variables operating on host subpopulations and of extrinsic variables across the collective host population on the distributions of 10 common helminth species from coyotes in south texas were compared. the intrinsic variables of host sex and presence and severity of sarcoptic mange had little effect on the distributions of most helminth species. the combined influences of (1) seasonal changes across the collective host population and (2) host subpopulations deli ... | 1984 | 6512639 |
| transmammary infection of paratenic and definitive hosts with alaria marcianae (trematoda) mesocercariae. | transmammary infection with alaria marcianae mesocercariae was demonstrated using mice as model, paratenic hosts. prenatal transmission was ruled out because neonates removed immediately postpartum from infected dams were never infected. mesocercarial distribution in virgin females and in females examined immediately postpartum showed no marked preference for the mammary glands. in contrast, infection of neonates that were allowed to suckle on infected dams was absolute, and the number of mesoce ... | 1983 | 6631639 |
| migration of alaria marcianae (trematoda) in domestic cats. | the migration of alaria marcianae was studied in domestic cats. mesocercariae penetrated the stomach wall, entered the abdominal cavity, and penetrated the diaphragm within 3 hr. direct penetration of the lungs via the thoracic cavity occurred within 6 hr. also observed was a circulatory route to the lungs when mesocercariae were recovered from both the liver and the chambers of the heart. upon entrance into the lungs, mesocercariae began to enlarge with sequential lappet formation, holdfast dev ... | 1983 | 6672170 |
| transmammary infection of newborn by larval trematodes. | newborn cats and mice became infected with alaria marcianae if they nursed from females that had been experimentally infected with the parasite. all lactating females showed mesocercarial stages in their mammary glands. this may be the first trematode found to undergo transmission through the mammary glands under experimental conditions. similarities in the behavior of mesocercariae in humans and in the mouse suggest that an infected human female might infect her infant if she elected to nurse i ... | 1984 | 6695195 |
| epidemiology of alaria marcianae mesocercariae in louisiana. | natural infections of alaria marcianae mesocercariae were detected in five amphibian, seven reptilian, and two mammalian species in louisiana. alligators were susceptible to experimental infections with mesocercariae. natural infections were also found in the subcutaneous fat of raccoons and opossums. examination of three gravid opossums showed a marked preference of the mesocercariae for the mammary glands, however, we were unable to find transmission of mesocercariae to any of the 27 young. ba ... | 1981 | 7328467 |
| persistence of a recurrent group of intestinal helminth species in a coyote population from southern texas. | the persistence and interrelationships of a recurrent group of intestinal helminth species in a coyote population from southern texas were determined; data were collected at 4-yr intervals (1979, 1983, and 1987). the a priori expectation was that a defined recurrent group of helminth species persisted over time and that the respective helminth species were stable in terms of their abundances. the fager index and subsequent recurrent group analysis indicated a small group of taxonomically unrelat ... | 1993 | 8501593 |
| effect of short-term coyote removal on populations of coyote helminths. | coyote (canis latrans) removal programs often are initiated despite the potential population regulatory mechanism of parasitism with increased coyote density. we investigated the effect of intensive, short-term coyote removal on population levels of helminths in juvenile and adult coyotes from western texas. coyotes were killed by aerial gunning every 3 mo for 2 yr on two 5,000 ha areas, which reduced the overall coyote density of these areas by about 50%. two other 5,000 ha areas were used as c ... | 2002 | 11838229 |
| helminths of the ocelot from southern texas. | in the usa, the ocelot (leopardus pardalis) is a highly endangered felid found only in a few remaining vestiges of native thornshrub brushland in the lower rio grande valley (lrgv) of extreme southern texas. from 1987-1998, carcasses of 15 adult ocelots that died of vehicular accidents or natural causes were examined for helminths. all cats had 1-8 (mean = 3) helminth species. all were infected with 1-101 (mean +/- se = 32 +/- 7) toxascaris leonina. other helminths from these ocelots were alaria ... | 2003 | 14567231 |
| gastrointestinal helminths of free-ranging florida panthers (puma concolor coryi) and the efficacy of the current anthelmintic treatment protocol. | thirty-five florida panthers (puma concolor coryi [bangs, 1899]) collected from six counties in southern florida between 1978 and 2003 were examined at necropsy for gastrointestinal helminths. the panthers were placed into two groups: 1) treated with anthelmintics (n = 17), and 2) untreated (n = 18). nine species of helminths (one trematode, six nematodes, and two cestodes) were identified in the untreated panthers. the most prevalent helminths were alaria marcianae (larue, 1917) (100%), spirome ... | 2006 | 16870865 |
| transmammary infection of free-ranging florida panther neonates by alaria marcianae (trematoda: diplostomatidae). | two freshly-dead female florida panther (fp) neonates, puma concolor couguar (=puma concolor coryi), an 11-day-old and a 17-day-old, were collected in the florida panther national wildlife refuge (26 degrees 14'n, 81 degrees 36'w), collier county, florida. the 2 neonates were siblings and had presumably fed only on milk from the dam since birth. a 12-day-old female fp neonate was collected in the big cypress national preserve (26 degrees 05'n, 81 degrees 15'w), collier county, florida and had al ... | 2009 | 18665664 |
| alaria mesocercariae in the tails of red-sided garter snakes: evidence for parasite-mediated caudectomy. | trematodes of the genus alaria develop into an arrested stage, known as mesocercariae, within their amphibian second intermediate host. the mesocercariae are frequently transmitted to a non-obligate paratenic host before reaching a definitive host where further development and reproduction can occur. snakes are common paratenic hosts for alaria spp. with the mesocercariae often aggregating in the host's tail. in the current study, we used morphological examination and molecular analyses based on ... | 2015 | 26337267 |
| modelling potential presence of metazoan endoparasites of bobcats (lynx rufus) using verified records. | helminth parasites of wild and domestic felines pose a direct or potential threat to human health. since helminths depend on multiple environmental factors that make their transmission possible, it is imperative to predict the areas where these parasites may complete the transmission to potential hosts. bobcats, lynx rufus (schreberer), are the most abundant and widely-distributed wild felid species in north america. the increase of population densities of bobcats raises concerns about their imp ... | 2014 | 25549497 |
| epizootic and zoonotic helminths of the bobcat (lynx rufus) in illinois and a comparison of its helminth component communities across the american midwest. | a total of 6257 helminths of 19 taxa were recovered from the digestive tract and lungs of 67 bobcats in illinois. infections caused by alaria mustelae, diphyllobothrium latum, and macracanthorhynchus ingens are reported for the first time in bobcats. from all the taxa recovered, only three species occurred in high prevalence and caused intense infections: taenia rileyi, alaria marcianae, and toxocara cati, with prevalence and mean intensity of 70% and 6; 42% and 193, and 25% and 14 individuals, ... | 2014 | 24521984 |
