Pneumococcus Type

1. The antigenic function of a pneumococcus vaccine made from the intact cell was compared with that derived fron a watery extract of the cell free from formed elements. In each instance, the immunity produced was dependent upon type-specific protective substance and not upon the elaboration of the common protein antibody. 2. The vaccine made from the intact cell resulted in both active and passive immunity which began on the 3rd day, increased markedly to the 5th, and remained approximately stationery to the 7th day. In the case of the Berkefeld filtrate of the shaken bacteria and the filtrate of the broth culture, the immunity began on the 4th day, increased to the 5th, and remained approximately stationery to the 7th day. The immunity produced by Pneumococcus Type I vaccine is greater than that produced by Type II. On the 3rd day, mice vaccinated with Type I vaccine resisted 100,000 minimal lethal doses, whereas mice immunized with Type II resisted 10,000 minimal lethal doses. On the 5th day, a larger percentage of mice survived these doses than on the 3rd day. 3. Certain factors related to the preparation and dosage of the vaccine are discussed. 4. As far as the time interval and the degree of immunity produced are concerned, these results suggest the possibility of employing pneumococcus vaccine in suitable doses in the treatment of lobar pneumonia. That an earlier activity of the immunity mechanism could actually be initiated in a patient with lobar pneumonia has still to be demonstrated.

The prevalence of infection and the identification of anisakid larvae in European hakeMerluccius merluccius lessepsianusfrom Hurghada City, Red Sea Governorate, Egypt, were investigated. Fish samples were collected during the period of February and November 2014. Twenty-two (36.66%) out of sixty examined fish specimens were found to be naturally infected withAnisakistype I larvae mostly found as encapsulated larvae in visceral organs. There was a positive relationship between host length/weight and prevalence of infection. Based on morphological, morphometric, and molecular analyses, these nematodes were identified as third-stage larvae ofAnisakis simplex. The present study was considered as the first report of anisakid larvae from European hake in the Egyptian water.

AbstractPaleolithic remains, mostly surface finds from blowouts, are known from 63 sites in the Trans-Baikal, one of the five large regional subdivisions of the Siberian Paleolithic. Most important recent discoveries are the stratified sites of Oshurkovo and Sannyi Mys and the Pleistocene faunal sequence on Tologoi Mountain. Characteristic stone tools are made from whole or split pebbles and from blades removed from prismatic cores. Bone artifacts, known only from Oshurkovo, include slotted points and knives and flat antler harpoons. The Trans-Baikal finds, all Upper Paleolithic in time, are tentatively arranged in five chronological stages. The earliest period is based on the lower levels at Sannyi Mys in which microblades, but no pebble tools, are found with woolly rhinoceros and mammoth. The next period is represented by large pebble tools and cores from Ust"-Kiakhta Locality 3. Typical Siberian pebble tools found with horse in the upper levels at Sannyi Mys are assigned to the third stage. The fourth is best known from Oshurkovo where all the common Siberian Paleolithic stone tools are found along with bone artifacts in deposits which contain abundant fish bones. A number of sites are assigned to the fifth stage, but it is best represented by the uppermost level at Oshurkovo where flakes, flaked pebbles, and small blade tools of regular outline replace the large blades and pebble cores of the earlier periods. This tentative sequence is strengthened by correlations with the Angara and Yenisei areas to the west and with Mongolia and North China to the east. The Trans-Baikal is seen as an area in which the prismatic core and blade tradition of Eurafrican origin and the split pebble-tool tradition of eastern Asia were in contact from the earliest known period.

A New Species

A new species of sucking louse, Hoplopleura zyzomydis, is described and illustrated from the common Australian rock rat Zyzomys argurus (Thomas, 1889) (Rodentia: Muridae), collected in northwest Queensland, Australia. This is the first record of a sucking louse from the genus Zyzomys, and its morphology is contrasted with other Australian Hoplopleura species. Hoplopleura zyzomydis is unique in having a combination of short dorsal principal thoracic setae and setae absent from paratergal plates 4–6. A key to the Australian species of Hoplopleura is presented.

Abstract The regulatory roles of the common cytokine receptor γ chain (γc)– and Jak3-dependent signaling in the proliferation and survival of mast cells were determined using γc-deficient (γc−) and Jak3-deficient (Jak3−) mice. Although the mast cells in γc− and Jak3− mice were morphologically indistinguishable from those in wild-type mice, the number of peritoneal mast cells was decreased in γc− and Jak3− mice as compared with that in wild-type mice. Among γc-related cytokines, interleukin (IL)-4 and IL-9, but not IL-2, IL-7, or IL-15, enhanced the proliferation and survival of bone marrow–derived mast cells (BMMCs) from wild-type mice. However, the effects of IL-4 and IL-9 were absent in BMMCs from γc− and Jak3−mice. In addition, IL-4Rα, γc, and Jak3, but not IL-2Rβ or IL-7Rα, were expressed in BMMCs. In contrast, IL-13 did not significantly induce the proliferation and survival of BMMCs even from wild-type mice, and IL-13Rα1 was not expressed in BMMCs. Furthermore, IL-4 phosphorylated the 65-kd isoform of Stat6 in BMMCs from wild-type mice but not from γc− and Jak3− mice. These results indicate that γc- and Jak3-dependent signaling is essential for IL-4– and IL-9–induced proliferation and survival of murine mast cells, that the effects of IL-4 are mediated by type I IL-4R and that type II IL-4R is absent on mast cells, and that IL-4 phosphorylates the 65-kd isoform of Stat6 in mast cells in a γc- and Jak3-dependent manner.

Several, not fully mobile, ,juvenile Planigale maculata, a small terrestrial marsupial, were observed calling from exposed positions near to where they had emerged from their nests. This is the first record of an audible vocalization of the planigale. An oscillogram of their call is presented. At the same time several tawny frogmouth (Podargus stringoides) were calling from surrounding trees. Many P. stringoides were observed picking off the P. maculata from the tree trunks throughout the night.
