The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
The Multi-Individual Cremation Phenomenon Of The Santa Cruz Drainage, Karl J. Reinhard, T Michael Fink
Karl Reinhard Publications
Multi-individual cremation deposits found in the upper Santa Cruz River drainage were previously interpreted as the result of hypothesized cultural contact in the area. A review of 50 cremation deposits for which detailed analyses are available indicates that mulii-individual cremation deposits are the result of incomplete gleaning practices and have doubtful cultural significance. Hypotheses are generated from the present data which account for the apparent variation in cremation practices within the study area.

Effects Of Trypanosoma Musculi Kendall, 1906 Immune Serum On The Reproduction Of Trichinella Spiralis (Owen, 1835) Railliet, 1896 In Mice, Samuel L. Chafin
Loma Linda University Electronic Theses, Dissertations & Projects
The possible effects of ablastin, a reproduction-inhibiting antibody which is produced during the infection of the blood parasite, Trypanosoma musculi in the mouse, were investigated by fractionating the parasite into a supernatant fraction (designated as Group A test mice) and a pellet fraction (Group B test mice). These groups A and B mice were injected with the respective fractions, plus Freund’s Complete Adjuvant (FCA). Control mice were injected with FCA only. Sera from these three groups of mice were removed after the Group A and Group B mice were shown to be negative to T. musculi challenge, and Group A …

Prehistoric Cremations From Nogales, Arizona *, Karl J. Reinhard, Jeff H. Shipman
Karl Reinhard Publications
In October, 1969, the Highway Salvage Section of the Arizona State Museum conducted emergency salvage excavations in conjunction with the construction of the Tucson-Nogales Highway. Ten cremations were recovered from a backhoe trench which had been placed within the city limits of Nogales, Arizona. Analysis of the cremations indicated cultural contact between the Trincheras culture of Sonora, Mexico, and the Hohokam culture of the Santa Cruz River Valley in southern Arizona.
Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman
Parasites Of Channel Catfish In Illinois Hatcheries, Charles Dale Meryman
Masters Theses
Ninety channel catfish (Ictalurus punctatus) were trapped during September 1973 through April 1974 at three hatcheries located at Worden, Centralia, and Kinmundy, Illinois. All were examined for parasites and 87 were parasitized. The trematodes Azygia angusticauda and Neascus sp. were found in the gastrointestinal system and Cleidodiscus floridanus and Dactylogyrus sp. were attached to the gills. Five cestode genera, including Bothriocephalus sp., Corallobothrium giganteum, Eubothrium sp., Haplobothrium sp., and Proteocephalus ambloplitis were present. Rhabdochona sp. was the only nematode found. Protozoans; Costia sp., Myxobolus sp., Scyphidia macropodia and Trichodina discoidea and one kind of glochidium were observed. …
The Great Potato Debate, James D. Hudson
The Great Potato Debate, James D. Hudson
Honors Theses
Anencephaly and spina bifida cystica are two of the most common severe congenital malformations consistently observed in human populations. Both represent defects in the neural tube and share a significant number of similar epidemiological associations among them, occupational class, geography, sex ratio, maternal age, year and season of the year. In anencephaly most of the brain and upper skull never form usually resulting in death within a few hours of birth. Spina bifida cystica is a malformation of the spinal cord often causing paralysis, vulnerability to infection, and early death. In 1972, Dr. J.H. Renwick presented a controversial hypothesis which …
Lice Of Public Health Importance And Their Control, Harry D. Pratt, Kent S. Littig
Lice Of Public Health Importance And Their Control, Harry D. Pratt, Kent S. Littig
Harold W. Manter Laboratory of Parasitology: Library Materials
Lice have been intimately associated with man for centuries. Infestations with lice occur today in the United States and many other countries despite great efforts to maintain high standards of public health. Public health agencies are often called upon if infestations include or expose large groups of people, particularly those in public institutions such as schools, jails, hospitals, or homes for the aged.
The three sucking lice that infest humans are: the body louse (Pedlculus humanus humanus), the head louse (Pediculus humanus capitis), and the crab louse (Pthirus pubis). The body louse is the …
Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann
Bibliography Of Diseases And Parasites Of Marine Fish And Shellfish (With Emphasis On Commercially Important Species), Carl J. Sindermann
Harold W. Manter Laboratory of Parasitology: Faculty Publications
The literature on diseases and parasites of marine animals has been accumulating at an accelerating rate in recent decades, and at a seemingly geometrical rate in the past few years. Reviews of selected aspects of the subject have appeared (Cheng, 1967; Sindermann, 1966; Sindermann and Rosenfield, 1967). References listed in these papers include a significant, but still a small part, of the available literature. With the proliferation of journals in many languages throughout the world, a complete bibliography, even in a narrow area of research, is almost an impossibility. Then too, the daily appearance of new published information represents an …
Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson
Sheep Worm Control And Lambing Time In High Rainfall Areas, F C. Wilkinson
Journal of the Department of Agriculture, Western Australia, Series 4
Indications from a continuing sheep trial at Margaret River are that farmers in high rainfall areas could increase stocking rates and lamb growth rates by lambing in September- October rather than July-August.
The results also indicate that farmers in the area may be spending more than necessary on worm control.
Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.
Some Aspects Of Carbohydrate Metabolism In The Cercariae Of Schistosoma Mansoni Sambon, 1907, A. Eugene Dunham Jr.
Loma Linda University Electronic Theses, Dissertations & Projects
Cercariac of Schistosoma mansoni were studied for glycogen utilization, uptake of glucose from solution, lactic acid production, and respiration.
Using the anthrone method of determination of carbohydrate, the amount of glycogen used by a single cercaria in 4 hours is determined as 43.2 x 10-4 μg ± 6.6 x 10-4 μg.
Glucose was not observed to have been used from solution under the conditions of the experiment, even in the presence of trehalose. The determinations were made by the Glucostat method.
After deproteinization and desugarization, aliquots of supernatant from cercarial suspensions were analyzed for lactic acid using p-phenylphenol …
A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal
A Brief History Of The Namru-3 Medical Zoology Program, Harry Hoogstraal
United States Naval Medical Research Unit 3: Publications
The NAMRU-3 Medical Zoology program began during Easter week of 1950. We had just closed the NAMRU-3 field station at Torit, in Equatoria Province of soulheastern Sudan, and were heading homeward to the United States. However, the offer to remain in Egypt for a year or two to develop a Medical Zoology department at NAMRU-3 provided an interesting challenge after working for several years in tropical forests and grasslands of Africa and other continents. We shall briefly describe subsequent events under four headings: (1) Medical Zoology in Egypt, (2) Ticks and Tickborne Diseases of the World, (3) Kala Azar in …

Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter
Carbon Dioxide Fixation In Schistosoma Mansoni, Clint Earl Carter
Loma Linda University Electronic Theses, Dissertations & Projects
Adults of the blood fluke Schistosoma mansoni were perfused from the hepatic portal system of CF1 female mice sixty to seventy days post infection. The worms were then incubated in Eagle’s minimal essential medium with glutamate and 0.03 mg/100 ml of nonlabelled aspartic acid. To this medium was added 10 μc of either NaH1403, glucose-UC14 or aspartate-4-C14. The worms were found to fix carbon from the NaH1403 and to incorporate the glucose and aspartate. The amount of activity recovered in five different chemical fractions after two hours incubation was determined …
The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck
The Effect Of Schistosoma Mansoni On Free Amino Acid Levels In Mice, Richard D. Tkachuck
Loma Linda University Electronic Theses, Dissertations & Projects
Free amino acid levels in the blood plasma of mice infected with Schistosoma mansoni Sambon, 1907, were measured at 3, 6, and 9 weeks post-infection with an automatic amino acid analyzer. Significant differences between experimental and control animals occurred at all three time periods. At 3 weeks, asparagine, alanine, citrulline, proline, methionine, and threonine levels all were lower in the infected animals. At 6 weeks, four differences were noted. Alpha-amino-n-butyric acid, ornithine, lysine, and histidine all had lower values in infected animals. At 9 weeks there were 12 differences. Tyrosine, phenylalanine, threonine, serine, proline, citrulline, glycine, alanine, valine, isoleucine, and …

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes
United States Naval Medical Research Unit 3: Publications
Over the past several years a large number of references from the USSR, Eastern Europe, and China have been collected dealing with arthropods of medical importance. These references were coded on keysort cards which made it possible to index as many as fifteen subject areas on one card. The usefulness of this indexing system was evident by the number of medical entomologists who used it in searching for references in their specialty. In response to requests from workers in the United States and other countries who did not have ready access to the index. it was decided to publish these …
Lupinosis In Sheep. 1. Laboratory Studies, M R. Gardiner, M. C. Nottle
Lupinosis In Sheep. 1. Laboratory Studies, M R. Gardiner, M. C. Nottle
Journal of the Department of Agriculture, Western Australia, Series 4
IN earlier articles by Bennetts (1957, 1960), the clinical and pathological features of lupinosis, as seen in field outbreaks, were described.
The suggestion was made that the roughage portion of the lupin plants was responsible for the disease.
More recent observations suggest a relationship between parasitism and lupinosis.
Natural History Of Thelazia Californiensis Price, 1930 (Nematoda: Thelaziidae), A Mammalian Eye Worm, Warren E. Parmelee
Natural History Of Thelazia Californiensis Price, 1930 (Nematoda: Thelaziidae), A Mammalian Eye Worm, Warren E. Parmelee
Loma Linda University Electronic Theses, Dissertations & Projects
Various factors—embryology, host associations, and seasonal changes In eye worn populations—tending to promote the propagation of T. califomlensls were studied.
The early embryology closely parallels that of other nematode species.
The mature embryos remain alive in saline at 35°C as long as 5 days. Dead embryos can be distinguished from living ones by virtue of the rapid staining by methylene blue by the former. Parturient female thelazias release embryos into saline, and embryos are found regularly in tear secretions of infected laboratory rabbits.
Ovic embryos possess an enveloping egg membrane containing chitin. On this account, this eye worm species is …

Natural And Experimental Infections Of Thelazia Californiensis Price (1930, Nematoda: Thelaziidae) With Descriptions Of The Adult And Larval Parasites, Howard S. Burnett
Loma Linda University Electronic Theses, Dissertations & Projects
The purpose of this work was to determine the extent and effects of infestation of the eye worm of mammals, Thelazia californiensis, and to elucidate through experimentation or observation the mode of transmission.
A survey of literature revealed that thelaziasie (infestation by Thelazia species) may cause serious pathological changes in the eye and its adnexa, sometimes resulting in blindness. It was found that reports of thelaziasis in the United States were (with two exceptions) of cases in California. It was further found that T. californiensis has been reported in a wider variety of host than has any of other …

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
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 …
