Some Additional Observations On The Morphology Of Dendrouterina Botauri Rausch, 1948 (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The scolex has never been described for cestodes of the genus Dendrouterina Fuhrmann, 1912. The two species belonging to this genus, D. herodiae Fuhrmann, 1912, and D. botauri Rausch, 1948, were described from incomplete material. Because of the lack of a scolex, this genus was only tentatively placed by Fuhrmann (1912) in the family Dilepididae.
Persistent collecting during the spring migration of 1948 made possible the examination of a number of bitterns, Botaurus l. lentiginosus (Montagu). A single bird, collected on May 5, 1948, at Madison, Wisconsin, was found to be infected with two specimens of Dendrouterina botauri. Observations …

The Occurrence Of Platynosomum Illiciens (Braun, 1901) In A North American Hawk., J. Fred Denton, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A series of 160 hawks of 12 species from ten states and the Province of Manitoba has been examined for dicrocoeliid trematodes. Only one species of dicrocoeliids was found in them indicating the infrequency with which North American hawks are infected with trematodes of this group.

Of the 160 hawks examined 4 were broad-winged hawks. Buteo platypterus, 2 of which, collected in Ohio and Wisconsin, harbored in their bile ducts 3 and 8 specimens respectively of a trematode of the genus Platynosomum. These specimens, after comparison with both the original and the recently expanded description by Travassos (1944, …

Some Observations On Cestodes Of The Genus Paranoplocephala Luehe, Parasitic In North American Voles (Microtus Spp.), Robert Rausch, Everett L. Schiller

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Although cestodes of the genus Paranoplocephala Luehe, 1910, are common parasites of voles and certain other rodents in North America, their taxonomic status to the present time has been much confused. It is the purpose of this paper to clarify the situation in regard to those species parasitic in voles of the genus Microtus Schrank.

While certain of the cestodes considered here occur in hosts of other microtine genera, they are by far more abundant in the various species of Mi· crotus. At least two are also common in geomyid rodents. With the possible exception of Paranoplocephala brevis Kirschenblatt, …

Studies On The Parasitic Helminths Of The North Central States. Ii. Helminths Of Voles (Microtus Spp.) Preliminary Report, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The helminths of North American mouse-like rodents have received little study. Previous work has been based on low numbers of animals examined, and there has been little reference to the ecology involved. The purpose of this paper is to present data resulting from the examination of over 600 voles, with special reference to host-parasite relationships

Observations On Cestodes In North American Owls With The Description Of Choanotaenia Speotytonis N. Sp. (Cestoda: Dipylidiinae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Little is known concerning the helminths parasitic in several major groups of the North American avifauna. This appears to be particularly true of the parasites of owls. Over the past few years the writer has had the opportunity of examining a fairly large series of these birds, and they have been found to be infected with several helminths of unusual interest (Chandler and Rausch, 1947).

A Contribution To The Study Of Certain Avian Strigeids (Trematoda), Asa C. Chandler, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of more than 200 species of birds by Rausch during the past few years, has disclosed a number of interesting strigeids, some of which are considered in the present paper. Three species appear to be undescribed and two of these are of particular interest in that they occur in passeriform birds, a group rarely parasitized by strigeids. In addition to the descriptions of the new species, remarks concerning Hysteromorpha triloba (Rudolphi, 1819) are included.

Studies On The Parasitic Helminths Of The North Central States. I. Helminths Of Sciurida, Robert L. Rausch, Jack Tiner

Harold W. Manter Laboratory of Parasitology: Faculty Publications

It is accepted that a fair degree of completeness is being achieved in our knowledge of North American mammals and birds. It can be assumed that nearly all the described species of the higher vertebrates are parasitized by helminths, but many of these helminths probably remain undescribed, and little is known of their geographical distribution. Very little information is available on the incidence of the parasites, or their effect on the host.

Sarcocystis (Aspergillus?) In Wood Warblers [General Notes], George H. Breiding, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

On August 9, 1944, near Columbus, Ohio, Breiding collected an immature male black and white warbler (Mniotilta varia). Upon preparing it as a study skin, the bird was found to be heavily infected with Sarcocystis. This experience was repeated with an adult male Mourning Warbler (Oporornis philadelphia), taken near Cheat Bridge, Randolph County, West Virginia, June 14, 1945. Both birds appeared to be in healthy condition.

Two species of wood warbler, the olive-backed warbler (Parula pitiayumi) and the American redstart (Setophaga ruticilla) have previously been recorded as hosts for this organism …

Dendrouterina Botauri N. Sp., A Cestode Parasitic In Bitterns, With Remarks On Other Members Of The Genus, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A single cestode belonging to the genus Dendrouterina Fuhrmann, 1912, was taken from the small intestine of a least bittern, Ixobrychus e. exilis (Gmelin), collected by the writer on May 31, 1945, at Buckeye Lake, Ohio. Considerable difficulty was experienced in obtaining adequate material of this cestocde, although bitterns were collected in Ohio, Michigan, Wisconsin, and Manitoba. A second infected bird, an American bittern, Botaurus l. lentiginosus (Monatgu), was collected on April 24, 1947, at Horicon Marsh, Wisconsin. Three specimens of Dendrouterina were obtained from this bird.
Unfortunately, since refrigeration was not available in the field, the scolices of all …

Bakererpes Fragilis N. G., N. Sp., A Cestode From The Nighthawk (Cestoda: Dilepididae), Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of an Eastern Nighthawk (Chordeiles m. minor (Forster)), collected September 25, 1945, at Marion, Ohio, revealed numerous, very small cestodes free in the lumen of the small intestine. About fifty specimens were found, but, because of the delicate strobila of this species, few were entire.
Although these cestodes were very thin and translucent, the preparation of well-stained whole mounts presented unusual difficulty. Best results were obtained with a mixture of Ehrlich's and Delafield's haematoxylin stains. Frontal and transverse serial sections, cut at 10 and 15 μm, were made.
This cestode clearly belongs in the sub-family Dilepidinae, but, …

The Digenetic Trematodes Of Marine Fishes Of Tortugas, Florida, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Library Materials

189 species of digenetic trematodes are reported from teleost fishes of the region of Tortugas, Florida. Among these are recognized: 44 new species, 9 new genera, 44 new combinations, 14 new synonyms, and 51 new host records. Several genera and species are considered synonyms of those previously named.

Of 237 species (approximately 2,039 specimens) of teleost fishes examined, 182 species or 76.8% were parasitized by adult, digenetic trematodes. Most of the host species harbored from one to three species of trematodes; 79 (or 43.4% of the 182) had a single species of trematode. Two fishes, however, were each susceptible to …

Observations On Some Helminths Parasitic In Ohio Turtles, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The examination of a number of turtles, collected in Ohio, has disclosed at least thirty-three species of parasitic helminths. Little information is available on the parasites of turtles in the Central States, and it is the purpose of this paper to present data resulting from examinations made on 128 turtles, of seven species.

Extension circular 1549 discusses external parasites of chickens and DDT.

Suggestions For The Handling Of Certain Mammals, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

For experimental work, it is often desirable to handle the smaller wild mammals more freely than usual methods allow. Howell (Journal of Mammalogy (1937) 18(4): 513) suggests the feeding of pentobarbital sodium in milk or other food. While this may be satisfactory for animals accustomed to captivity, it can hardly be used for those newly captured.

Pullorum Disease In The Coot, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among specimens collected on March 8, 1945, at Buckeye Lake, Ohio, were a number of coots (Fulica americana). When the latter were examined for parasitic infection, it was noticed that the ovary of one specimen was deformed, and much enlarged when compared with those of other birds of this species collected on the same day. No other lesions were detected macroscopically, and the bird appeared to be in normal physical condition. The ovaries resembled those found in chickens affected with pullorum disease, and a pure culture of Salmonella pullorum was recovered.

A Redescription Of Taenia Taxidiensis Skinker, 1935, Robert Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Since the original description of Taenia taxidiensis Skinker, 1935,2 was based on an incomplete and apparently immature cestode, a redescription seems desirable.

The following description is based on 28 cestodes, taken from three infected badgers, Taxidea taxus (Schreber), all collected in southern Wisconsin. Of these, only one strobila had gravid segments, the others being immature. Most of the data given below are based on the single mature specimen, with additional measurements, where Possible, from the immature worms. No sections were made of these specimens, and the measurements given were taken fl·om stained wholemounts.

Andrya Sciuri N. Sp., A Cestode From The Northern Flying Squirrel, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Among helminths taken from four northern flying squirrels (Glaucomys sabrinus macrotis Mearns) were two cestodes belonging to the genus Andrya. These represent an undescribed species. The infected flying squirrels were collected in or near tamarack bogs during February, 1947, near Millston, Jackson County, Wisconsin.

Morphology Of A New Species Of Bat Cestode, Hymenolepis Roudabushi, And A Note On Hymenolepis Christensoni Macy, Ralph W. Macy, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examination of material of a species of Hymenolepis collected by Rausch from several species of bats taken near Marysville, Ohio, revealed that it was new. A series of specimens of the same species was collected in 1942 at Ames, Iowa, by Dr. Robert Roudabush. The new species, Hymenolepis roudabushi, is described.

New Records Of Macracanthorhynchus Hirudinaceus In Sciuridae, Robert L. Rausch

Parasites Of Ohio Muskrats, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Parasites of the muskrat (Ondatra zibethica) have received considerable study, but little in Ohio. From March 20, 1943, to March 22, 1945, 70 Ohio muskrat carcasses were examined, most of them being obtained from trappers by Merrill C. Gilfillan, Leader of the Pittman-Robertson Muskrat Project in Ohio. The specimens were from seven localities: Lake Erie Marshes (28); Killbuck Valley Marsh (17, lacking liver and lungs); Walnut Creek (19) and Whetstone Creek (2), (Morrow County); Buckeye Lake (1); Little Scioto River, Marion County (1); and Union County near Marysville (2).

The Plains Garter Snake, Thamnophis Radix, In Ohio, Roger Conant, Edward S. Thomas, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The announcement that Thamnophis radix, the Plains garter snake, occurs in Ohio and is not rare in at least one county, will surprise most herpetologists and students of animal distribution. Since the publication of Ruthven's monograph on the genus (1908), almost all authors have followed his definition of the range of this species, giving eastern Illinois as its eastern-most limit. Ruthven (p. 80), however, believed that radix very probably would be found in western Indiana, a supposition since substantiated by Schmidt and Necker (1935: 72), who report the species from the dune region of Lake and Porter counties.

Notes On The Trematode Subfamily Loimoinae (Monogenea), With A Description Of A New Genus, Harold W. Manter, Waldo L. Schmitt

Harold W. Manter Laboratory of Parasitology: Library Materials

The subfamily Loimoinae was named by Price (1936) for a peculiar monogenetic trematode, Loimos salpinggoides MacCal lum, 1917, from the gills of a dusky shark, Carcharias obscurus (Lesueur), at Woods Hole, Massachusetts, USA. Price (1938) redescribed this trematode, correcting several errors made by MacCallum. Manter (1938) described Tricotyle scoliodoni from a shark, Scoliodon terrae-novae (Richardson), from Beaufort, North Carolina, USA. He noted some similarities between Tricotyle and Loimos. The redescription of Loimos by Price increased these similarities.

A New Genus Of Distomes (Trematoda) With Lymphatic Vessels, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The trematodes described in this paper are but two of over 100 species collected from marine fishes in 1934, during the third G. Allan Hancock Expedition to the Galapagos Islands. The author's presence on this expedition was sponsored in part by the Carnegie Institution of Washington. A brief preliminary report on the trematodes collected has been made (Manter, 1934) and a more complete report on the digenetic forms is in preparation. An early description of these two forms is felt justified in view of their significance in connection with the phylogeny of the Distomata. The author has already indicated (Manter, …

Digenetic Trematodes Of Fishes From The Galápagos Islands And The Neighboring Pacific, Harold W. Manter

Harold W. Manter Laboratory of Parasitology: Faculty Publications

During January, February, and March of 1934 it was the· privilege of the writer, aided by the Carnegie Institution of Washington, to accompany the third Allan Hancock Expedition to the Galápagos Islands. A preliminary note concerning the trematode parasites collected has been published. Several papers dealing with various helminths collected have appeared. The present paper deals with the digenetic trematodes collected from fishes. Five hundred and thirty-two fishes, including nearly one hundred different species, were examined. Approximately 80 per cent of the species and 43 per cent of the individuals harbored some kind of trematode. Meserve records 22 species of …

The Gizzard Worm And Its Transmission To Chickens In Hawaii, Joseph E. Alicata

Harold W. Manter Laboratory of Parasitology: Library Materials

Gizzard-worms of poultry, Cheiloapirura hamulosa, are nematodes occurring in the gizzards of chickens and turkeys.

Summary and Conclusions

Previous to this report the carriers for the gizzard-worm in Hawaii were unknown. Recent investigations by the writer have shown that the flour beetle, Tenebroides nana, and the sand hopper, Orchestia platensis, collected from poultry farms in the Territory of Hawaii have been found naturally infested with the infective larvae of the poultry gizzard-worm, Cheilospirura hamulosa. Out of 8 laboratory-raised chickens to which there were fed about 2,300 grasshoppers that had been collected in an endemic gizzard-worm area, …

Some Monogenetic Trematodes From The Galapagos Islands And The Neighboring Pacific, Frank Grose Meserve

School of Biological Sciences: Dissertations, Theses, and Student Research

Introduction

Trematodes are parasitic, unsegmented, flattened (rarely cylindrical) worms. They have ventral, anterior, posterior or median attachment organs. The sense organs are poorly developed. The mouth is terminal or ventral and subterminal. The intestine is usually forked with or without lateral branches. The animals, with few exceptions, are hermaphroditic. The ovary is usually single. They have one, two, or more testes. The development is direct with only one host in the ectoparasitic Monogenea and indirect in the Digenea which have two or more hosts. The digenetic trematodes usually parasitize vertebrates which serve as their primary hosts and invertebrates (Mollusca) which …
