Purification And Sanitary Control Of Water (Potable And Waste), Paul W. Kabler

United States Public Health Resources

Although most of the streams draining inhabited regions are contaminated with human or animal feces, water-borne disease today in the United States is relatively uncommon. Pathogenic enteric microorganisms probably do not multiply in raw water sources under normal conditions. They usually disappear in a relatively short time, with the rates depending on variations in environmental conditions. Urban water supplies have played a diminishing role in the transmission of intestinal disease because of improvements in the detection and enumeration of pollution indicators, water and sewage treatment processes, and t h e sanitary control of water systems.

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 …

The Ecology Of Mosquito Borne Viruses, Carl M. Eklund

United States Public Health Resources

The ecology of a mosquito borne virus involves a consideration of the growth of the virus within the vertebrate and arthropod hosts, the reaction of these hosts to the presence of the virus, and the vertebrate-arthropod associations which are necessary for the dissemination and maintenance of the virus. Little is known of the physiological properties of a particular host and virus which permit multiplication of the virus. In this review stress will be laid u pon studies which attempt to discover the mechanisms in nature which maintain these viruses. The first section will relate to the geographical distribution and time …

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. Naval Medical Research Unit no. 3, Cairo, Egypt.

United States Naval Medical Research Unit 3: Publications

This work was done in the laboratory and in the field and includes questions of development, behavior, and viability of ticks, their propagation and season of attack.

H. marginatum: Two-host tick, larvae and nymphs parasitize mainly birds, also hares, adults on, all kinds of domestic animals.

This tick inhabits the southern areas of the Soviet Union. Northern boundary of mass propagation is 46 to 49.5° northern latitude and yearly isotherms +90. Host heavily infested are lowlands and foothills of steppe, forest steppe; and low mountain forest zone. In high mountain belts and deserts, this tick is rare. Birds must …

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

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.

Census of Hallucinations

May I ask for the publicity of your pages to aid me in procuring co-operation in a scientific investigation for which I am responsible? I refer to the "Census of Hallucinations," which was begun several years ago by the Society for Psychical Research, and of which the International Congress of Experimental Psychology at Paris, last summer, assumed the future responsibility, naming a committee in each country to carry on the work.

The object of the inquiry is twofold: lst, to get a mass of facts about hallucinations which may serve as a basis for a scientific study …
