Bulletin No 3883 - Dairying In W.A., Western Australian Department Of Agriculture

Bulletins - 3000 - 3999

Western Australia has a small dairy industry compared with its other rural production. However, the industry has consolidated over recent years.

Tree clearing and pasture development on existing holdings and the amalgamation of small dairy farms has led to a rapid increase in the area of pasture per farm. The trend in Western Australia is towards bigger herds, more efficient dairies, more fodder conservation and increasing production per cow and per· hectare.

Virus-Associated Tumours Of The Harderian Gland In Laboratory-Reared Voles, Clethrionomys Rutilis (Pallas), Robert L. Rausch, J. W. Lindsay

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Tumors of the Harderian gland occurred frequently in red-backed voles, Clethrionomys rutilus (Pallas), in a captive colony maintained since 1957. Although the tumors became obvious only in animals about a year old and older, early stage changes were histologically evident in glands from younger, clinically normal voles. The tumors ranged in type from poorly differentiated adenoma to adenocarcinoma, with invasion of adjacent tissues and characteristic deformation of the zygomata. Electron micrographs disclosed viral particles in the cytoplasm of glands from clinically normal animals as well as in glands showing malignant changes. The tumor was not observed in arvicoline rodents of …

More Information On The Coccidian Parasites (Protozoa: Eimeriidae) Of The Colorado Pika, Ochotona Princeps, With A Key To The Species, Donald W. Duszynski

Harold W. Manter Laboratory of Parasitology: Faculty Publications

The prevalence of 7 species of Coccidia is reported from 137 Colorado pikas, Ochotona princeps, collected on Mt. Evans, Clear Creek County, Colorado, during the summers of 1968, 1969, and 1971. Identification of the parasites was based on the structure of the unsporulated oocysts which, at least for those species that have been described to date from North American pika hosts, are highly distinctive for most species. Photographs illustrate the differences in size, shape, and form of the oocysts of the various species. A key to the Coccidia of pikas, based on the descriptions of sporulated oocysts, is presented.

Physiological And Morphological Correlation Of Rhizopus Stolonifer Spore Germination, James L. Van Etten, Lee Bulla Jr., Grant St. Julian

Department of Plant Pathology: Faculty Publications

Sporangiospores of Rhizopus stolonifer were examined at various stages of germination by scanning electron and phase-contrast microscopy. These observations were correlated with changes in spore dry weight, spore volume, respiration, and syntheses of ribonucleic acid, deoxyribonucleic acid, and protein during germination.

Some Digenetic Trematodes From Synaphobranchid Eels, Robin M. Overstreet, Douglas M. Martin

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Four trematodes, all new host records, were found in synaphobranchid eels from the continental slopes in the Gulf of Mexico and the Straits of Florida. Hypertrema ambovatum Manter, 1960 (Fellodistomidae), previously known only from near New Zealand, is reported from Synaphobranchus oregoni, including data in addition to the original description; Pseudopecoelus vulgaris (Manter, 1934) (Opecoelidae) and Hirudinella sp. (Hirudinellidae) are reported from S. affinis and S. oregoni, respectively, and commented upon briefly; and Helicometra robinsorum sp. n. (Opecoelidae) is described from S. oregoni and Ilyophis brunneus. The latter trematode most closely resembles H. antarcticae Holloway and Bier, …

Helminth Parasites Of Illinois Wild Turkeys, James W. Jackson

Masters Theses

Viscera from 69 wild turkeys (Meleagris gallopavo silvestris) collected from Jackson, Union and Alexander counties, Illinois, were examined for helminth and coccidian parasites. A total of eight species of parasites was found, all in the alimentary tract. The coccidian parasite Eimeria sp. was found in 9.6% of birds examined. The nematodes Heterakis gallinarum, Ascaridia galli and Ascaridia dissimilis were found in 13.2%, 27.9% and 48.5% respectively of all birds examined. Three species of cestodes, Raillietina williamsi, Metroliasthes lucida and Hymenolepis sp., were recovered from 41.1%, 27.9% and 1.4% respectively of birds examined. One species of trematode, …

An Estuarine Low-Temperature Fish-Kill In Mississippi, With Remarks On Restricted Necropsies, Robin M. Overstreet

Gulf and Caribbean Research

In January 1973, large numbers of Mugil cephalus (striped mullet), weighing approximately 250 gm each, died in two freshwater localities in tidewater bayous of Jackson County, Mississippi. Fish identified as Mugil curema, M. cephalus, Megalops atlantica, Dormitator maculatus, and Fundulus grandis were found dead in other low saline estuarine areas. Fish-kills during cold periods are less commonly encountered in Mississippi than in Texas or Florida. This particular incident is attributed to conditions of stress for fishes incompletely acclimated to the encountered low temperatures. The most deleterious stress was the low saline water which probably allowed a …

A Rubber Band Around An Atlantic Croaker, Robin M. Overstreet, Charles H. Lyles

Harold W. Manter Laboratory of Parasitology: Faculty Publications

A rubber band permanently girdled an Atlantic croaker, Micropogon undulatus, resulting in considerable malformation and pathological alterations of the fish. On 12 July 1973 at Graveline Bayou, Jackson County, Mississippi, Mrs. Buster Blades caught on hook and line a 175 mm standard length (102.1 g) croaker that she immediately separated from the rest of her catch as a suspected parasitized fish. Later upon closer examination, she realized that a rubber band encircled the fish, and so she brought the fish to us. The band had deformed the prepelvic isthmus, restricted movement of the pectoral fins, and permanently encircled the …

Efficacy Of Betaprone With Ultraviolet Irradiation On Hepatitis B Antigen In Human Plasma Pools (A Retrospective Study), Gerald A. Logrippo, Hajime Hayashi

Henry Ford Hospital Medical Journal

In a retrospective study, hepatitis B antigen (HB Ag) was found in 14 lots of human plasma pools (16-20 liters each) that had been treated by the combined Betaprone (BPL) with ultraviolet (UV) irradiation procedure. No evidence of clinical hepatitis was found during a six-month follow-up after 185.2 liters of HB Ag positive plasma were Infused into 257 patients. Since HB Ag positive blood products treated by BPL with UV produced no clinical hepatitis, it is evident that our treatment is efficacious against hepatitis virus agents.

Heligmosomoides Johnsoni Sp. Nov. (Nematoda: Heligmosomatidae) From The Heather Vole, Phenacomys Intermedius Merriam, Virginia R. Rausch, Robert L. Rausch

Harold W. Manter Laboratory of Parasitology: Faculty Publications

Heligmosomoides johnsoni sp. noy. is described from the cecum of the heather vole, Phenacomys intermedius Merriam, from the Olympic Mountains, Washington. The absence of longitudinal cuticular ridges dorsally separates H. johnsoni from species of Heligmosomoides other than H. hudsoni (Cameron, 1937), which occurs in varying lemmings, Dicrostonyx spp., and from which H. johnsoni is distinguished by its longer spicules, form of the dorsal ray, and other characters. Both Phenacomys and Dicrostonyx have a specialized cecum, with long villi around which the nematodes are found tightly coiled. The zoogeography of heligmosomid nematodes in Phenacomys is briefly discussed.

Nsca - Asc - National Plan For Biological Collections, Asc Committee

Harold W. Manter Laboratory of Parasitology: Faculty Publications

American systematics collections: A national plan. Developed by a stellar group of biologists including David Wake and Peter Raven, this plan called for action by the systematics community. The estimate of needs in 1973 called for about 63 million USD for the next five years just to keep the US National Collections from disintegrating and to get them in shape to mount the huge effort needed to fully inventory the biota of the earth (a plan that was not even dreamed of until about the year 1995).

A report to the nation's systematics collections community, and includes a National Plan …
