Dissimilar local risk factors among patients diagnosed with cystic echinococcosis upon voluntary screening in highly endemic regions of Kyrgyz Republic.

Echinococcosis is a parasitic invasion caused by a cestode of the genus . Kyrgyzstan is a country in Central Asia known for an extremely high incidence of echinococcosis. A total of 10 093 subjects were screened in the Osh, Naryn and Batken regions of Kyrgyzstan in 2015–2017 by ultrasound and questioned for potential risk factors.

In Search of a Target Gene for a Desirable Phenotype in Aquaculture: Genome Editing of Cyprinidae and Salmonidae Species.

Aquaculture supplies the world food market with a significant amount of valuable protein. Highly productive aquaculture fishes can be derived by utilizing genome-editing methods, and the main problem is to choose a target gene to obtain the desirable phenotype. This paper presents a review of the studies of genome editing for genes controlling body development, growth, pigmentation and sex determination in five key aquaculture Salmonidae and Cyprinidae species, such as rainbow trout (), Atlantic salmon (), common carp (), goldfish (), Gibel carp () and the model fish zebrafish ().

Toxocara prevalence in dogs, cats and the environment in Russia.

The toxocariasis incidence in Russia is relatively low (1.8 cases per 100,000 individuals) and the parasite is not a major healthcare concern. However, the proportion of primary hosts testing positive for the parasite is high and varies between 3% and 100% in dogs (on average 33%), and between 6% and 52% in cats.

Seroprevalence and incidence of human toxocarosis in Russia.

Overall incidence of toxocariasis in Russia is low and varies between 1.6 and 2.7 per 100,000, while in several hyper-endemic regions, such as Altay, Kurgan, Perm and Udmurtia, it reaches 43 per 100,000.

Precise U-Pb age constrains on the Ediacaran biota in Podolia, East European Platform, Ukraine.

The Neoproterozoic Era was characterized by rapidly changing paleogeography, global climate changes and especially by the rise and fall of the Ediacaran macro-biota. The correlation between disparate Ediacaran fossil-bearing localities and the tentative reconstruction of their paleoenvironmental and paleogeographic contexts are usually complicated by the lack of precise and accurate age data. For this reason, Neoproterozoic sedimentary sections associating Ediacaran biota fossils and fresh volcanic material are especially valuable for radioisotopic dating.

[Specific genetic features of the Russian forms of bovine leukemia virus].

Genetic peculiarities of bovine leukemia virus isolates (BLV) spread throughout Russia and Ukraine (BLV-1, BLV-2, and BLV-4) have been characterized based on pol gene polymorphism. Seven viral forms have been detected. The variability of BLV isolates did not exceed 1% within one form.

[Identification and classification of bovine leukemia virus isolates in Russia and Ukraine based on the pol viral gene polymorphism].

Bovine leukemia virus (BLV) is a widespread specific pathogen of cattle. Analysis of the pol viral gene polymorphism has been used to characterize the polymorphism of BLV isolates at stock-breeding farms in Russia and Ukraine. The fragments of the pol gene corresponding to the reverse transcriptase and integrase 494 and 233 bp in size, respectively, have been used for analysis.

[Comparison of ISSR polymorphism among cattle breeds].

Polymorphism analysis of DNA fragments flanked by (TC)9G and (CT)9G inverted dinucleotide microsatellite repeats in 766 animals of 19 cattle breeds and one breeding type revealed 66 fragments, of which 64 were polymorphic. The breeds proved to differ in the frequency and presence or absence of amplified DNA fragments at the genomic level, indicating that ISSR fingerprinting is informative for differentiating the PCR product spectra and cattle breeds. Multilocus ISSR polymorphism analysis identified the group of fragments that can be used as Bos taurus and B.

[Analysis of the genetic structure of Tuvinian short-fat-tailed sheep populations with the use of the ISSR-PCR method].

The genetic structure of populations of the Tuvinian short-fat-tailed sheep was studied with the use of the ISSR-PCR (Inter Simple Sequence Repeats) method in 18 farms of Tyva. Data on the spectrum of ISSR fragments of DNA were obtained using the (AG)9C primer. Analysis of intermicrosatellite polymorphism permitted us to determine genomic characteristics of the populations, their genealogical relations, and the parameters of genetic diversity within the populations and the breed as a whole.

[Polymorphism of the BoLA-DRB3 gene in the Mongolian, Kalmyk, and Yakut cattle breeds].

Polymorphism of the BoLA-DRB3 gene was studied with the use of the PCR-RFLP technique in three cattle breeds (Mongolian, Kalmyk, and Yakut) representing the Bos taurus turano-mongolicus group. 35 BoLA-DRB3.2 alleles were detected in the Mongolian breed and 34 alleles in the Kalmyk breed.
