On The Ecology And Distribution Of Echinococcus Spp. (Cestoda: Taeniidae), And Characteristics Of Their Development In The Intermediate Host. Ii. Comparative Studies On The Development Of Larval E. Multilocularis Leuckart, 1863, In The Intermediate Host, Masashi Ohbayashi, Robert L. Rausch, Francis H. Fay

Harold W. Manter Laboratory of Parasitology: Faculty Publications

This paper reports the results of a comparative study of the development of the larval Echinococcus multilocularis Leuckart, 1863), and associated tissue reaction in naturally and experimentally infected mammals representing 31 species. The histogenesis of the larval cestode was traced in detail in arvicoline rodents of several species, and interspecific differences were defined.

In arvicoline rodents, the developing larva exhibited host-specific characteristics within about a month after infection was established. The tissue reaction in Microtus oeconomus was characterized by the production of a large quantity of detritus around the larva, and by the formation of a thick epithelioid zone. In …

Rubella Immunization Of Adult Females Using Hpv-77 Dk-12 Live Attenuated Rubella Virus, Donald A. Romig, E. L. Quinn, Frank Cox, Robert G. Brackett

Henry Ford Hospital Medical Journal

This study demonstrates the serologic response as measured by the HAl test and the side reactions of the HPV-77 DK-12 live rubella vaccine in a small group of adult females. One hundred percent seroconversion was obtained using this vaccine. The mean titers obtained in two separate time periods post-vaccination are higher than those reported for several other rubella virus vaccines. A 66% occurrence of joint symptomatology was recorded post-vaccination with a mean duration of 11.6 days; 24% of women who received placebo reported joint complaints which had a mean duration of 2.0 days. The difference between these two rates is …

Glaucivermis Spinosus Gen. Et Sp. N. (Digenea: Zoogonidae) From The Southern Kingfish, Menticirrhus Americanus (Linnaeus), In The Coastal Waters Of Mississippi, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Glaucivermis spinosus is described from the intestine and pyloric ceca of Menticirrhus americanus collected near Ocean Springs, Mississippi, in the Gulf of Mexico and adjacent waters. The genus is characterized primarily by having a preacetabular intestinal bifurcation, a preacetabular sinistral genital pore, a bilobed vitellarium, a swelling of Laurer's canal to form the seminal receptacle, and tandem to diagonal testes. It is most similar to the genus Diphtherostomum from which it differs primarily in the arrangement of the testes.

Life History Of Philophthalmus Megalurus (Cort, 1914) In Western Oregon, Toni Anne Mcmillan

Dissertations and Theses

The specific identification of a megalurous cercaria found in the snail Oxytrema plicifera was accomplished by completing the life cycle in the laboratory. This species is compared with the eastern Philophthalmus megalurus and P. gralli with which it was once confused. The eggs, miracidia, and rediae of the Oregon species were found to be similar to those of the above species. The body and organ sizes and sucker ratios for the cercariae and adult stages obviously indicate that the Oregon species is Philophthalmus megalurus.

Bacteriuria As A Precursor Of Intracatheter Encrustation, Namcy Moll

Loma Linda University Electronic Theses, Dissertations & Projects

The problem with which this study was concerned was the development of criteria that could be used to determine when urinary catheter changes were necessary. By determining when encrustation occurred, it was felt that some complications could be eliminated by changing catheters before obstruction occurred due to encrustation.

It was the purpose of this study to: 1) explore some indications for catheter change, 2) determine if encrustation of urinary catheters necessitates catheter change, and 3) estimate potential criteria for a routine time for catheter changes.

Forty-five catheters were examined after their removal from patients. Flow rates were determined on 33 …

The Effect Of Elevated Glucose On Neutrophilic Phagocytosis In Genetically Diabetic Mice, Larry B. Thompson

Loma Linda University Electronic Theses, Dissertations & Projects

Infiltration to an injury site or area of bacterial contamination by polymorphonuclear leucocytes (or neutrophils) is an early and essential phase of the early inflammatory reaction. Their action on foreign matter is the most critical step taken by body defense mechanisms in the first 24 hours. Anything which interferes with that action, phagocytosis, greatly hampers early inflammation. This study was designed to see the effect of elevated glucose levels on neutrophil phagocytosis in a unique strain of genetically diabetic mice.

Twenty-two diabetic and twenty-four control female mice were used. Blood glucose determinations and total white counts were made on each …

The Response Of Gingival Tissues To Alterations In Ph, Robert C. Jann

Loma Linda University Electronic Theses, Dissertations & Projects

The purpose of this study was to evaluate the histopathological and clinical changes that occurred when a continuous supply of exogenous acid or base, at varying pH, was delivered adjacent to the gingival crest of the monkey. A related goal was to develop a monkey model system which would deliver test solutions continuously and atraumatically, to the experimental gingival sites.

Two young adult female monkeys had a perfusion apparatus attached to certain maxillary teeth so that test solutions were deposited atraumatically to the marginal gingival tissues. During the experimental periods the animals were kept in primate restraining chairs and fed …

Serum Lipids And Urinary Estrogens Of Non-Pregnant Menstruating Young Women, Shiao-Fan Lee

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Twelve university women students served as experimental subjects in a study of the serum lipids and urinary estrogens of healthy nonpregnant menstruating young women, who were living under their usual conditions.

The subjects maintained constant weight on their ordinary diets during the entire study period. Antecubital blood and 24-hour urine specimens were collected on certain days which represented different stages of the menstrual cycle. Quantitative analyses were made on serum total cholesterol, lipid phosphorus (phospholipids), triglycerides and total lipids. Gas-liquid chromatographic analysis of the fatty acid composition of each serum lipid component was also made. Urinary estrone, 17β- estradiol and …

Influence Of Temperature Of Incubation And Type Of Growth Medium On Pigmentation In Serratia Marcescens, Robert P. Williams, Cora L. Gott, S M. Qadri, Randolph H. Scott

Faculty, Staff and Student Publications

Maximal amounts of prodigiosin were synthesized in either minimal or complete medium after incubation of cultures at 27 C for 7 days. Biosynthesis of prodigiosin began earlier and the range of temperature for formation was greater in complete medium. No prodigiosin was formed in either medium when cultures were incubated at 38 C; however, after a shift to 27 C, pigmentation ensued, provided the period of incubation at 38 C was not longer than 36 hr for minimal medium or 48 hr for complete medium. Washed, nonpigmented cells grown in either medium at 38 C for 72 hr could synthesize …

The Somatic Chromosomes Of Some North American Marmots (Sciuridae), With Remarks On The Relationships Of Marmota Browerii Hall And Gilmore, Robert L. Rausch, Virginia R. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Karyotypes are defined for two nearctic species of marmots, Marmota olympus (2n = 40) and M. vancouverensis (2n = 42), and supplemental information is included on the karyotypes of M. flaviventris, M. monax ochracea, and M. marmota. The six North American species of Marmota (NF = 66) comprise a distinct group as compared with the middle Asian species (NF = 70) for which the karyotypes are known. Karyologic findings and zoogeographic evidence based upon the distribution of two nearctic species of host-specific cestodes indicate that M. broweri, in northern Alaska, is a pre-Würm relict. Its affinities …

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The cryptogonimid trematode Neochasmus sogandaresi n. sp. is described from the intestine and pyloric caeca of a single specimen of the striped bass Morone saxatilis (Walbaum, 1792) from the West Pascagoula River in Mississippi. The species is 1.3–1.7 mm long and has 31–37 oral spines, a sucker width ratio of 1:0.45–1:0.54, a forebody 13–18% of the body length, and an elongated muscular pad. It is compared with the five other species in the genus.

Observations On Parasite-Host Relationships Of Echinococcus Multilocularis Leuckart, 1863, In North Dakota, Robert L. Rausch, S. H. Richards

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Red foxes, Vulpes vulpes (Linnaeus), and small mammals were collected and examined during 1965-1969, to investigate parasite-host relationships of Echinococcus multilocularis Leuckart, 1863, in North Dakota. Comparative studies of this cestode were carried on concurrently through experimental infection of carnivores and rodents. In winter, red foxes in North Dakota exhibited high rates of infection of comparatively low intensity. Deer mice, Peromyscus maniculatus (Wagner), and voles, Microtus pennsylvanicus (Ord), were important intermediate hosts, but the larvae in deer mice produced fewer protoscolices. The strains of E. multilocularis from North Dakota and from St. Lawrence Island, Alaska, differ biologically, as indicated by …

Two New Species Of Digenea From The Spot, Leiostomus Xanthurus Lacépède, From The Gulf Of Mexico, Robin M. Overstreet

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Two new species of Digenea are described from the euryhaline fish, Leiostomus xanthurus, from near Ocean Springs, Mississippi. The first, Apocreadium manteri, is most like A. uroproctoferum Sogandares-Bernal, 1959, from which it differs by having multispined scales and larger eggs and not possessing a uroproct. The second, Lecithaster leiostomi, is most like L. gibbosus (Rudolphi, 1802) from which it differs primarily by having a more elongated seminal vesicle and stockier vitelline lobes. Lecithaster musteli Srivastava, 1966, is considered a synonym of L. confusus Odhner, 1905.

Studies On The Helminth Fauna Of Alaska. Xlix. The Occurrence Of Diphyllobothrium Latum (Linnaeus, 1758) (Cestoda: Diphyllobothriidae) In Alaska, With Notes On Other Species, Robert L. Rausch, D. K. Hilliard

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Cestodes representing six species of the genus Diphyllobothrium Cobbold, 1858, were collected from naturally infected terrestrial mammals in Alaska during the period 1949-1970. Additional specimens were reared in experimentally infected animals. Of the species identified, viz., D. latum (Linnaeus, 1758), D. dendriticum (Nitzsch, 1824), D. lanceolatum (Krabbe, 1865), D. ursi Rausch, 1954, D. dalliae Rausch, 1956, and D. alascense Rausch and Williamson, 1958, all but D. alascense were obtained from man after treatment with quinacrine. D. latum occurred most commonly in humans; D. ursi is reported for the first time from this host, and D. lanceolatum in humans was represented …

Lasiotocus Trachinoti Sp. N. (Digenea: Monorchiidae) From The Pompano, Trachinotus Carolinus (Linnaeus), Along The Coast Of Florida, Robin M. Overstreet, Charles E. Brown

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The monorchiid trematode Lasiotocus trachinoti sp. n. is described from the intestine and the pyloric ceca of young Trachinotus carolinus. It is most like L. mulliof Bartoli and Prévot, 1966, but differs from it primarily by being smaller and having cirrus spines more evenly dispersed.

Increase In Size Of Eimeria Separata Oocysts During Patency, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Examinations of 18 consecutive fecal samples collected at 6-hr intervals from infected rats showed that oocysts increased in length and width by approximately 40% from the beginning to the end of the patent period. Unsporulated oocysts were first observed in the 3rd fecal collection, 84 to 90 hr post-inoculation (PI) and 100 of these measured 9.9 to 14.3 by 8.8 to 12.1 μ (mean 11.7 by 10.1). Patency ended with the 15th fecal collection, 156 to 162 hr PI, and 100 unsporulated oocysts from this sample measured 14.3 to 17.6 by 13.2 to 15.4 μ (mean 16.3 by 14.2). Despite …
