[Distribution characteristics of Leishmania tropica major strains of differing virulence in natural and territorial complexes of the Murgab eco-area (southeastern Turkmenistan)].

In September--October of 1973 and 1974 263 specimens of Rhombomys opimus were shot in the territory of the Murghab stationar. The seeding of the material (a piece of tissue) from all animals into NNN medium was done. 9 strains of L. tropica major were isolated from this material the virulence of which was studied on 2.5--3 months--old golden hamsters, Cricetus auratus. Differences in the virulence of the isolated strains according to their natural-territorial complexes are shown. These differences depend apparently on the specific composition of the vectors. It is shown that the specific composition of sand flies as well as other epizootical characters are determined by the landscape of the territory where nidi of zoonosis cutaneous leishmaniasis are situated.

[Study of the circulation of Crimean hemorrhagic fever virus in Turkmenistan].

Final results of the virological and serological investigations of the circulation of the Crimean hemorrhagic fever virus in the Turkmenian SSR carried out in 1968-1976 are presented in this report. In the examination of 2294 blood serum samples of human beings complement binding antibodies against the Crimean hemorrhagic fever were revealed in 0.4% of cases. It was revealed that five species of ixodes ticks could he infected with this virus; for the first time its strains were also isolated from the Hyalomma dromedarii ticks. Isolation of the Crimean hemorrhagic fever virus from ticks and determination of the precipitating antibodies against this virus in agricultural animals--from 6.2 to 11.1%--in all the regions of the republic pointed out that the natural nidi zones were widespread at the territory of the Turkmenian SSR, and that it was necessary to carry out further study of the given focus.

Field and experimental studies of poxvirus infections in rodents.

Data are presented from serological and virological investigations of natural and experimental infections, in rodents, with different poxviruses. The demonstration of poxvirus antibodies (virus neutralizing antibodies, antihaemagglutinins, and precipitins) in the kidneys and/or lungs of rodents from Europe and Africa, and the isolation of poxviruses from them, all indicate that rodents may be poxvirus carriers. Isolates from rodents differed in their properties. Some, from Turkmenistan rodents or from white rats caught near Moscow, appeared to be very close to cowpox virus, while others (from Zaire rodents) were identical to variola-like (whitepox) viruses found earlier in monkeys in the same region. The results suggest that rodents that carry the virus closely similar to cowpox virus might be a source of infection for other animal species.

Identification and study of a poxvirus isolated from wild rodents in Turkmenia.

A new poxvirus was isolated in 1974 from the kidney of a wild big gerbil (Rhombomys opimus) caught in Turkmenia, where these gerbils are wide-spread. The virus resembles cowpox virus and is markedly different from the virus of infectious ectromelia, the best-known poxvirus of rodents. The new virus is apparently identical to other poxvirus isolates made from white rats and Felidae in the Moscow Zoo. Experimental inoculation of the natural hosts--big gerbils and yellow susliks (Citellus fulvus)--produced a severe infection with a high mortality rate. Trnasmission of virus to uninoculated cage mates was shown to occur. Virus persisted in convalescent animals and was present in urine 3 weeks after inoculation and in kidney and testis for at least 5 weeks after inoculation. The role of rodents as natural hosts of poxviruses is discussed.

Virus "Tamdy"--a new arbovirus, isolated in the Uzbee S.S.R. and Turkmen S.S.R. from ticks Hyalomma asiaticum asiaticum Schulee et Schlottke, 1929, and Hyalomma plumbeum plumbeum Panzer, 1796.

Eleven virus strains were isolated from ticks Hyalomma asiaticum asiaticum Schulce et Schlottke, 1929, and Hyalomma plumbeum plumbeum Panzer, 1796,collected in 1971-1974 in desert regions of the Uzbee S.S.R. and the Turkmen S.S.R. According to CF test the strains were closely related to each other and not antigenically connected with viruses from antigenic groups A, B, California, CHF-Congo, Bakau, Bunyamwera, Gajam, Kaisodi, Qalyub, Kemerovo, Quaranfil, Simbu, Turlock, Hughes, Uukuniemi, Tete and 21 ungrouped viruses isolated from ticks. The virus was named "Tamdy" after the place of isolation of a prototype strain LEIV-1308 Uz. The virus does not agglutinate goose erythrocytes, it is pathogenic for suckling mice and 3 weeks old mice by intracerebral infection. Replication of a virus with CPE in cell cultures--L, Rh, A1--and without CPE--in pig embryo kidney cell cultures--was demonstrated. According to ultrafiltration and electron microscope data the size of the virus is about 90 nm. It is rather sensitive to lipid solvents and is an RNA-virus. Morphologically the virus resembles the Bunyaviridae.

Chromosomal polymorphism in Equus hemionus.

The first cytogenetic studies of the Turkmenian kulan, Equus hemionus kulan, are reported, and a polymorphism in diploid chromosome number is described. Chromosome fusion is apparently involved in the alterations of the karyotype of E. hemionus kulan (2n = 55, 54) when compared to the karyotype of the onager, E. hemionus onager (2n = 56). Additionally, the rearrangement involved has been identified in animals unrelated through captive breeding; inheritance of the fusion chromosomes has also been observed.

[Comparative karyological study of lizards of family Agamidae. II. Karyotypes of 5 species of the genus Agama].

Chromosome complements of the following species were described: Agama sanguinolenta Pallas, 1813; A. caucasica Eichwald, 1813; A. erythrogastra Nikolsky, 1896; A. lehmanni Nikolsky, 1896; and A. hymalayana Steindachner, 1867. Agama sanguinolenta has 46 chromosomes, all of them being telocentric. The remaining 4 species show 2-n equal to 36:6 pairs of meta- or submetacentric macrochromosomes and 24 microchromosomes. Sex chromosomes have not been found. Possilbe evolutionary interpretation of a profound karyologic divergence in the genus Agama and karyotypic relationships of Agamidae with Iguanidae of the New World, are discussed.

[Serological study of nontriturated fleas following preliminary cultivation of the plague microbe].

Under experimental conditions there was shown a possibility of serological study of nontriturated fleas for the presence of Past. pestis. Hottinger's broth with gentian-violet ((0.0003%) sodium sulfite (0.03%) and a surfactant--O (see article)-7 (3%) served as the growing medium. After the nontriturated fleas were grown for 48 hours at 37 degrees C the capsular antigen was detected with the aid of the passive hemagglutination and antibody neutralization tests. Detection of the capsular antigen in the growing medium pointed to the presence of Past. pestis in the fleas. To test the serological method of study the nontriturated fleas, the insects were collected in the colonies of Rhombomys opimus Licht. at the epizootic territory. The collected fleas were divided into portions (each portion contained not more than 20 fleas). Half of the portions of each collection was studied after trituration by the usual bacteriological method, and another--by serological method without trituration of the insects. In examining the parallel portions (a total of 2400 portions, about 32 000) it appeared that positive results were obtained by both methods with about the same frequency.

[Comparative evaluation of several methods of identifying leishmania].

A parallel study of 25 strains of Flagellata isolated from 6 species of sand flies was carried out by means of biotest, Adler's serological method modified by Safjanova and "temperature" method. It was established that the use of several methods for the identification of Leishmania allows more reliable results to be obtained. The differentiation of strains with the "temperature" method can be done over a relatively shorter period of time.
