The Fecal Shedding Of Listeria Monocytogenes By Conventional And "Germ Free" Mice, Margaret Joyce Ramsay

Loma Linda University Electronic Theses, Dissertations & Projects

A series of experiments involving Listeria monocytogenes was undertaken to study first the fecal shedding of Listeria by conventional mice challenged intraperitoneally with Listeria and second the fecal shedding and ability to survive of germ free mice with similar challenge. In addition, mites infesting Listeria infected mice were cultured for their possible contamination by Listeria.

Conventional mice were challenged intraperitoneally with a single near LD₅₀ dose of Listeria. Fecal Listeria were detected by collecting specimens from each mouse daily for the first 4 days and every second day thereafter. The feces was held at 7°C for 14 …

Control Of Lice On Pigs, Department Of Agriculture, Western Australia

Journal of the Department of Agriculture, Western Australia, Series 4

LICE are responsible for serious losses in the pig industry, as apart from the reduced growth rates and loss of condition resulting from the constant irritation, the lice are carriers of disease.

Lice And Keds In Sheep, C R. Toop

Journal of the Department of Agriculture, Western Australia, Series 4

BODY LICE and the so called ticks or keds are the most serious of the external parasites which infest sheep in Western Australia.

Unless they are controlled by systematic dipping, these pests can cause considerable financial loss to flock owners.

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 …

Ticks Affecting Animals In Australia, J Shilkin

Journal of the Department of Agriculture, Western Australia, Series 4

WHILE there are many external parasites affecting animals in Australia, information in regard to their geographical distribution and incidence is far from complete.

However, there is little doubt that the ticks, and in particular, the cattle tick, are the most important of these parasites in Australia.

We are fortunate that many species are not present in this country, as some of them are carriers of serious diseases of both man and animals.

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 …

United States Naval Medical Research Unit 3: Publications

First paragraph:

On 18 May 1954, (a specimen of) Burhinus oedicnemus (L.) was killed in the Lenkoransky region of Azerbaijan S.S.R.; on its head a male Amblyomma lepidum Dönitz, 1909, was found. Morphological characters of this tick, size and shape of body, characteristic light and dark ornamentation of dorsal shield, punctation, shape, and two colors of festoons, size and shape of cervical and lateral grooves, hypostome, peritreme, projection on coxae, and spherical orbited eyes correspond to those in the description of A. lepidum, given in Robinson monograph. Only on four anterior festoons a small light spot is found (in …

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, …
