All used test-systems detected apparent serotype-specific activity (homologous reaction) as well as cross-reacting virus-specific antibodies that was accounted for some reasons related to conservative epitopes in amino acid sequence of FMDV virion capsid VP1–VP3 polypeptides, accessibility of internal conservative epitopes of VP4 polypeptide for the animal’s immune system during virus replication or vaccine antigen (virus) destruction in the animal’s body in the process of immunity development, as well as the pilot anti-FMD vaccine composition, etc. Nevertheless, the analysis of a large data set (about 3,500 tests) showed that the homologous serotype-specific reaction in general was significantly higher and predominant, the proportion of virus-specific non-protective antibodies, including cross-reacting ones, was not significant and did not distort the results of ELISA tests of anti-FMD vaccine for its immunogenicity. Inconclusive test results require confirmation with other serological tests. Complex tests for FMDV using different diagnostic methods such as ELISA with standard and reference test-systems and/or virus neutralization test in cell culture are to be considered as the best option.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":" 52","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391956","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mycobacterium avium can grow and replicate in organic wastes from the poultry farms for a long time thus contaminating vast adjacent areas and being the source of infection not only for wild and domestic animals but also for humans. The studies were aimed at the examination of the duration of Mycobacterium avium survival in the natural environment in two geographical regions of the Republic of Dagestan characterized by different soil and climate. Samples of Mycobacterium avium-contaminated feces and soil collected from pastures and farmyards (on the surface and from 5 cm depth) were tested. The experiments demonstrated that pathogenic for chickens mycobacteria survived for up to 30 days in the samples collected in the sub-mountainous areas in summertime, when the air temperature ranged from 15.1 to 30 °С, land surface temperature – from 17 to 38 °С, air humidity – from 44 to 94% and average monthly precipitation amounted to 1.5 mm. From September to May, with the air temperature ranging from –10.8 to +25 °C, land surface temperature from –14 to +30 °C, air humidity 26–100% and average precipitation 0.39 mm, the bacteria survived for up to 213 days on the soil surface on the pastures and farmyards, and for up to 243 days at the depth of 5 cm and in the feces. In the plain area, in the same time period in the slightly saline soil with high humus content and at air temperature from –11.9 to +27.3 °C, soil temperature from –13 to +45 °C, air humidity from 37 to 100% and average precipitation 20.4 mm, Mycobacterium avium survived just like in the sub-mountainous area, i.e. for 213 and 243 days, respectively. The post-mortem lesions in the internal organs of the poultry corresponded to the tuberculosis clinical signs in 86 of 171 birds (50.3%). The study results will allow for the development of the optimal algorithm for animal health and management measures aimed at tuberculosis eradication on the poultry farms.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":" 7","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-03-15","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"140391329","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Nanocomposite silicon-zinc-boron-containing glycerohydrogel (Si-Zn-B-gel) may become a very good solution to the issue. The paper demonstrates wound-healing eﬀect of the glycerohydrogel and conﬁrms its eﬀectiveness for teat hyperkeratosis treatment indairy cows. Results of a rat burn model – based experiment suggest that Si-Zn-B-gel is a promising wound healing agent for topical use. Thus, on Day 9 complete re-epithelialization of the burn surface was observed, with ﬁbrous structures prevailing in the granulation tissue of the dermal layer, on Day 19 a mature scar was formed with a longitudinal alignment of collagen ﬁbers. The production tests conducted inhigh producing dairy cows have demonstrated good therapeutic eﬀect of the Si-Zn-B gel for teat-end hyperkeratosis and conﬁrmed its long-term eﬀect that helps to longer maintain the results achieved during treatment. After a 7-day treatment physiological structure of up to 27.8% teats improved, on Day 14 of the experiment no severe hyperkeratotic lesions were observed and the number of teats that correspond to the physiological norm was 72.2%. Analysis of the data collected shows that the Si-Zn-B-gel is eﬀective for teat-end hyperkeratosis treatment, thus, it prevents mastitis in animals and improves the milk quality.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":"25 11","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-12-20","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139168562","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently the disease causes significant economic damage in many countries. The Republic of China is the first country in Southeast Asia, which officially reported the African swine fever outbreak in 2018. The disease further spread to all provinces of the country with 200 outbreaks in domestic pigs and 10 outbreaks in wild boar in total; herewith the overall population of pigs de- creased dramatically, approximately by 180 million animals. Following the confirmation of the first African swine fever outbreak, the PRC Ministry of Agriculture and Rural Affairs launched the “African Swine Fever Contingency Plan and Emergency Response”, which facilitated the disease eradication and already by 2023, no new infection outbreaks had been reported. The country with the largest swine population in the world achieved rather moderate spread rates if compared to Europe. In addition, the virus strains, which circulated in the Chinese territory, were genetically diverse and different in virulence, leading to a wide range of clinical signs manifested by diseased animals. Such aspects were supposed to complicate the eradication measures, but instead, they proved their effectiveness. The experience gained from the disease control in China is most certainly of interest for the Russian Federation, infected with African swine fever since 2008.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":"192 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139344226","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Currently, the disease is widespread in many countries of the world. Many regions of the Russian Federation are anthrax-endemic. A large number of anthrax treatment, diagnosis and prevention tools are developed using hyperimmune serum. Currently known commercial hyperimmune sera are produced by 2-month long immunization of horses, which is a long and expensive process. This suggests the need to develop faster and cheaper ways to produce anti-anthrax hyperimmune sera; such possible ways became the objective of this study. A live culture of Bacillus anthracis 55-VNIIVViM vaccine strain, used to produce live vaccines against animal anthrax, was used in the experiments. Rabbits were used as animal models. Based on the findings the method of rabbit immunization was selected. The optimal method included intravenous injection of the antigen in increasing amounts according to the following scheme: injection I – 0.5 cm 3; injection II – 1 cm3; injection III – 2 cm3 at a dose of100million mc / animal in 1cm 3, with 4-day interval between injections. This scheme made it possible to produce the serum with a high antibody titer equal to 14 log2. For long-term storage of the serum produced, the freeze-drying modes were optimized, giving 2% residual moisture content of the finished product. The analysis of the freeze-dried serum storage terms showed that the initial activity and physico-chemical properties of the product are maintained for 30 months.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139346912","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are most commonly caused by fungi of the genera Micro sporum and Trichophyton. The identification of the agent’s species has a great epidemiological significance and is essential for effective therapy. The aim of the study is the identification and phylogenetic analysis of dermatophytes isolated from dogs and cats in the Republic of Kazakhstan and the Russian Federation by means of molecular techniques. The fungal isolate species were confirmed by sequencing using two rDNA internal transcribed spacer (ITS) primer pairs, and this allowed for their deposition to the GenBank database. Based on the sequencing results, Microsporum canis (12 strains) and Trichophyton benhamiae (2 strains) were identified. The nucleotide sequences were analysed, and phylogenetic trees were constructed, taking into account the results of the dermatophyte identification using two primer pairs. The constructed phylogenetic trees reflecting the relationships of dermatophytes showed that, irrespective of the primer pairs used, the Microsporum and Trichophyton pathogens are in all cases reliably assigned to different clades. The analysis of ITS4F/ITS5R sequence fragment structures enabled the establish- ment of genetic relatedness between the Trichophyton benhamiae strains first isolated from cats in Russia and the Russian strain recovered from a guinea pig. The comparative analysis of the genomes of the Microsporum and Trichophyton fungi and reference strains revealed a relatively low level of intraspecies polymor- phism and point mutations of the sequences. The data analysis demonstrated a high percentage of nucleotide sequence homology, and this allows using the primers for PCR tests intended for dermatophytosis diagnosis in cats and dogs.","PeriodicalId":507311,"journal":{"name":"Veterinary Science Today","volume":"16 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2023-09-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"139344807","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
