Formation and evolution of parasitism among Euglenoidina (Flagellata), parasites of Copepoda. P. 3-7.
The paper concerns stages of adaptation to parasitism in Euglenoidina, parasites of Copepoda. Parasites penetrating the host's egg at the initial phase of the parasitic link of the cycle are mainly considered. Phenomena of temporarily obligate parasitism as an intermediate link to stable obligate parasitism are also noted. Ontogenetic specificity of parasites is discussed. The presence of parasites that does not cause the death of hosts' larvae and proceeds after their reproduction is regarded as a completion of a certain stage in the evolution from zoophagy to parasitism.

Zn65 metabolism in chickens during coccidiosis caused by Eimeria tenella. P. 8-10.
The paper presents results of studies of Zn65 metabolism in various organs and tissues of chickens experimentally infected with Eimeria tenella. It was established that on the second day after the infestation Zn65 concentration in blood, plasm, erythrocytes and brain increases. At the most acute period of the disease the concentration of Zn65 remains very high. Besides, its specific activity rises in the liver and spleen and falls in blind processes. During the convalescent period the concentration of zinc in these organs and tissues gradually attains the norm.

Changes in the activity of intestinal phosphatases during experimental coccidiosis of chickens (Eimeria tenella and E. mitis). P. 11-15.
20-, 40-, and 60-days old chickens, sterile with regard to coccidiosis, were infected with pure cultures of Eimeria tenella and E. mitis by introduction of 5 thousand oocysts into the crop. After the slaughter, 3-d, 5-th, 7-th, 10-th, 20-th days from the infection, changesin the activity of alkaline and acid phosphatases of the small intestine were studied. The experiment consisted of six series conducted on 420 chickens. It was established that the activity of phosphatases of the small intestine changes in the process of the development of invasion. The degree of changes depends on species of Coccidia, age of the host and period of infection.

On dynamics of parasitemia during nuttalliosis of white mice. P. 16-18.
The dynamics of development of parasitemia during nuttalliosis (Nuttallia musculi Muratov, 1966) in white mice was studied. The incubation period, the degree of affection of erythrocytes during the development of parasitemia and the duration of circulation of nuttallians in peripheral blood were established.

Comparative characteristics of hyaluronidase activity of different strains of Entamoeba histolytica. P. 19-21.
The hyaluronidase activity of ten strains of Entamoeba histolytica isolated from sick persons and carriers was investigated. In determining ferment by the mucin method hyaluronidase activity is revealed only throught the analysis of concentrated samples. Long laboratory cultivation did not cause the loss of hyaluronidase but only reduced its activity. Hyaluronidase in the strains of E. histolytica is produced by amoebae themselves and its formation does not depend on the associated microflora.

Distribution of Burnet's rickettsiae in the tick Hyalomma asiaticum. P. 22-25.
Engorged mature ticks of Hyalomma asiaticum of both sexes were investigated. The same sections were treated with fluorescent gamma-globulins according to the direct Koons method and then were stained after Gieinsa-Romanowsky. An adopted view point of generalized nature of Q-rickettsial infection of ticks is confirmed. The highest content of rickettsiae is characteristic of derivatives of ectoderm and midgut. In addition to previous data, a massive dessimination of all four types of alveoli of salivary glands with rickettsiae was established. The agent was also found in the salivary duct. The obtained data suggest the possible excretion of rickettsiae from the organism of this tick not only with faeces but also through salivary secretion. The data point as well to the possibility of inoculative transmission of Burnet's rickettsiae by the tick to man and animals. The authors failed to find a causative agent in cells of the male genital system of the tick.

On the role of common parasitism of ixodid ticks in nidi of tularemia and Omsk hemorrhagic fever in the foreststeppe of West Siberia. P. 26-29.
In the lake region of the northern forest-steppe of West Siberia, in natural nidi of tularemia and Omsk hemorrhagic fever water voles and shrews of the genus Sorex are parasitized by Ixodes apronophorus and Dermacentor pictus. As regards the specific composition of these ticks the spring-summer-autumn season is represented by two periods. During the first period only I. apronophorus is feeding on animals while in the second one both species are parasitic simultaneously. Outbreaks of epizootia of tularemia occur, as a rule, in spring when females of I. apronophorus are active. That suggests their leading part in the circulation of the agent of this infection in swampy- lake natural nidi. Common parasitism of I. apronophorus and D. pictus favours the interspecific transmission of the tularemia agent. In July the combined parasitism is very important as a factor of the transmission of infection from swampy- lake nidi to meadow-field ones.

The duration of the life cycle of Hyalomma asiaticum Sch., Sclil. in natural biotopes. P. 30-34.
From 1966 to 1968 observations were undertaken on the development of Hyalomma asiaticum asiaticum in natural biotopes (burrows of great gerbils) in Turkmenia. Studies were carried out of engorged females, engorged immature ticks and their progeny. From April to October (warm period of the year) the duration of the whole life cycle was 103 to 132 days and 1.5 generation per year developed. Lower temperature thresholds and sums of effective temperatures necessary for the development of each phase of the life cycle were established.

The structure of female genitalia in bloodsucking mosquitoes of the subgenus Ochlerotatus (Diptera, Culicidae). P. 35-47.
The paper contains results of morphological studies of female genitalia in 14 species of bloodsucking mosquitoes of the subgenus Ochlerotatus inhabiting the territory of the Donetsk district of the Ukraine. There were distinguished distinct taxonomic characters which can be used for the determination of females to species.

Shelters of black flies. P. 48-53.
Shelters of black flies were investigated in the taiga zone of Priobje and in the places of the junction of tundra and forest-tundra of southern Yamal. The greatest number of black flies was recorded from crowns of trees, especially of coniferous ones (cedar, larch). Forest litter, burrows of rodents, and old passages of insects in wood can serve as shelters for black flies. Crowdings of black flies on plants are of short duration and hence are observed very rare.

Seasonal changes in the number and fauna of fleas in nests of Microtus arvalis Pall. in the environs of Odessa. P. 54-56.
On virgin land and on fields of filtration near Odessa there were obtained each month within a year nests of Microtus arvalis Pall. (ten nests per month in each habitat). On virgin land the most abundant in nests were Ctenophthalmus orientalis and Ceratophyllus consimilis (68 and 31% of the whole number of fleas). On fields of filtration two species were mostly often encountered in nests: C. consimilis and C. fasciatus Bosc. Index of abundance of all species of fleas per year was 67.5 on virgin land and 16.6 on fields of filtration.

On morphological differences between acanthocephals Bolbosoma turbinella (Diesing, 1851) (fam. Polymorphidae) from the northern and southern hemispheres. P. 57-64.
It was first established that acanthocephals Bolbosoma turbinella (Diesing, 1851) parasitizing whales in the northern and southern hemispheres have a number of morphological differences and belong as well as their hosts to different subspecies: northern one, В. turbinella turbinella (Diesing, 1851) subsp. n. and southern one, В. turbinella australis subsp. n. The paper contains descriptions of both subspecies.

Monogeneans of the family Plectanocotylidae Poche, new representatives of the subfamily Plectanocotylinae. P. 65-74.
Five new species of monogeneans of the family Plectanocotylidae were described and three new genera assigned to the subfamily Plectanocotylinae were erected. They are as follows: Triglicola tonkinensis g. sp. n., Т. dissimmetrica g. sp. n., Т. ocellata g. sp. n., Triglicoloides indicus g. sp. n., Inversocotyle pumilio g. sp. n. The above specimens were found in fishes from the Indian Ocean and the South-Chinese Sea. The authors suggests to include the genus Octoplectanocotyla Yamaguti, 1937, into the subfamily Plectanocotylinae Monticelli, 1903, and to reject the subfamily Octoplectanocotylinae Price, 1961.

The effect of certain antihelminthics on the glycogen content in tissues of cestodes Hymenolepis nana. P. 85-87.
The glycogen content changes taking place in tissues of cestodes (Hymenolepis nana) from the intestine of white mice after the introduction of aminoacrichin, phenasal and trichlorophene were determined. It was found that the introduction of aminoacrichin caused two or three fold reduction in the glycogen content as compared to the norm while phenasal and trichlorophene affected only mature forms reducing the glycogen content by a factor of 1.5 or 2. These antihelminthics are suggested to break the processes of absorption of formation and reservation of polysacharides common to this species or affect the processes of their utilization. These materials will serve as a basis for further investigations.

The filaria Setaria cervi (Rud., 1819) from the Deers. P. 89-90.
The author presents a new description of the Set aria from the abdominal cavity and central nervous system of deers (Cervus elaphus sibiricus Sew., 1873 and C. nippon hortulorum Swinhoe, 1864). Basing on the morphological characteristics, the Setaria of the Altay deers was referred to the species Setaria cervi (Rudolphi, 1819), while Setaria altaica Rajewskaja, 1928 has been considered as synonym of S. cervi.
