Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster Jan 1965

Review Of Echinococcus Species In South Africa, Anna Johanna Maria Verster

Harold W. Manter Laboratory of Parasitology: Faculty Publications

1. The nominate subspecies of E. granulosus (Batsch, 1786) is redesignated from the type locality, Europe.

2. Five subspecies of E. granulosus are described from South African carnivores: E. g. granulosus, E. g. africanus, E. g. felidis, E. g. lycaontis and E. g. ortleppi.

3. E. g. granulosus has so far only been recovered from the Transvaal; E. g. ortleppi appears to be restricted to the Transvaal; E. g. africanus occurs in the Orange Free State and the Transvaal; E. g. lycaontis and E. g. felidis like their definitive hosts are restricted to the Transvaal.

Index Catalogue To Russian, Central And Eastern European, And Chinese Literature In Medical Entomology, Volume 1: Diptera, George Anastes Jan 1963

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 …

Case Of Collecting Tick Amblyomma Lepidum Dönitz, 1909, In Azerbaijan, M. V. Pospelova-Shtrom, N. S. Abusalimov

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 …

Experiments In Transmission Of Theileriasis And Anaplasmosis Of Sheep Through Ticks Ornithodoros Lahorensis And Haemaphysalis Sulcata, P. A. Bitukov Jan 1953

Experiments In Transmission Of Theileriasis And Anaplasmosis Of Sheep Through Ticks Ornithodoros Lahorensis And Haemaphysalis Sulcata, P. A. Bitukov

United States Naval Medical Research Unit 3: Publications

First paragraph:

In conducting inspection of sheep on haemosporidiosis in some districts of South-Kazakhstankoi region, we repeatedly observed theileriasis and anaplasmosis of sheep.

Note: Numerous other experimental data in this paper are omitted from the present translation. This report is of special interest because it establishes the role of an argasid tick as a vector of blood protozoa. Translation made and distributed by Medical Zoology Department, U. S.

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings Sep 1914

Summary Of Two Years' Study Of Insects In Relation To Pellagra, Allan H. Jennings

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

With the growing interest in pellagra, following the authoritative recognition of its presence in the United States in 1907, the study of its etiology was taken up by various investigators and the several theories of causation were subjected to close scrutiny.

Prominent among these theories was that of insect transmission, first advanced by Sambon, who limited this function to the species of blood-sucking gnats comprising the genus Simulium.

The importance of the disease and the possibility of such a factor in its causation, led the Bureau of Entomology, late in 1911, to undertake an investigation of the subject …


Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley Sep 1914

Dr. Nott's Theory Of Insect Causation Of Disease, William A. Riley

Harold W. Manter Laboratory of Parasitology: Library Materials

Excerpt:

The danger in using isolated sentences from an article as a basis for interpreting the author's theories, is generally recognized, but sometimes the most careful workers fall into the trap. Once the mistaken interpretation is published, it may be copied over and over again until it rises to the dignity of a dogma.

A striking illustration is afforded by the practical unanimity with which writers on the subject of insects and disease credit Dr. Josiah Nott with being the earliest to formulate definitely the theory of mosquito transmission of yellow fever.

Nuttall, in his classic monograph On the Role …
