An outbreak of enteric disease unknown etiology with 60% morbidity and 8% mortality in weaning piglets occurred November 2015 on a farm Buryat Republic, Russia. Metagenomic sequencing revealed the presence rotavirus B feces from diseased while no other pathogens were identified. Clinical was reproduced experimentally infected piglets, yielding 11 RVB gene segments for strain Buryat15, an genotype constellation G12-P[4]-I13-R4-C4-M4-A8-N10-T4-E4-H7. This has also been identified United...

The article provides a comparative assessment of two experimental samples the seven-component vaccine KOMBOVAС-A , manufactured with adjuvants ISA 61 and 50, in terms of: antigenic activity (in laboratory naturally susceptible animals); influence on formation colostral immunity calves when vaccinating pregnant cows, as well effectiveness livestock farming conditions unfavorable for main respiratory intestinal diseases viral etiology. It was found that sample based adjuvant had higher...

Introduction. Rotavirus infection is one of the main concerns in infectious pathology humans, mammals and birds. Newborn piglets or rodents are usually being used as a laboratory model for evaluation immunogenicity efficacy all types vaccines against rotavirus A (RVA), use ELISA detection virus-specific antibodies specific isotype an essential step this evaluation.

We conducted a cross-sectional study to identify the major respiratory pathogen responsible for an outbreak of disease at swine farm in West Siberia 2019. discovered that peak morbidity and mortality coincided with high level porcine reproductive syndrome virus (PRRSV) 1 2-related viremia. Based on longer PRRSV2 viremia, dominant role over PRRSV1 was assumed. Phylogenetic analysis revealed strain belonged sub-genotype 2—one predominant groups genotype PRRSVs Russia. A partial open reading...

Results of the study structural composition bacterial and fungal microflora isolated from conjunctival swabs calves cows with clinical signs keratoconjunctivitis are given in this paper. Predominance among agents representatives coccal (staphylococci were found 85.06% animals, streptococci 74.71% animals) was revealed. Escherichia coli 74.71%, Proteus spp. 52.87%, Enterobacter 35.63%, Klebsiella 5.75% most frequently microorganisms Enterobacteriaceae. The occurrence frequency bacteria...

Introduction. Rotovirus infection (RVI) caused by the dsRNA-containing virus from genus Rotavirus, Reoviridae family, belonging to group A (RVA), is cause of severe diarrhea in human and other mammalian species. Vaccination most effective way reduce incidence RVI. At present, effectiveness using gnotobiotic piglets as a universal model for reproducing rotavirus assessing quality RVI vaccine preparations has been experimentally proven.Goals objectives. Evaluation immunogenic activity cloned...

Relevance . Rabbit haemorrhagic disease virus type 2 (RHDV-2, GI2,) was first detected in 2010 France and quickly spread across еuropean countries. Unlike strains of the genogroup, RHDV GI2 also affects rabbits under months old, as well various types hares. In addition, causes death vaccinated with vaccines based on 1 hemorrhagic viruses. The rabbit (RHDV-2) during an outbreak disease, characterized by sudden different age groups, summer 2019 a private farm Tula region, Russia. purpose this...
