Efficient delivery of the immunodominant genes of African swine fever virus by adeno-associated virus serotype 2.

Background And Aim: Adeno-associated virus serotype 2 (AAV2) represents a promising basis for developing a virus-vector vaccine against African swine fever (ASF). This study aimed to create genetic constructs based on AAV2 to deliver the immunodominant genes of ASF virus (ASFV) and to evaluate their functionality . The efficiency and specificity of transgene expression, as well as their non-toxicity in cells of target animals, were evaluated.

Viral Vector Vaccines Against ASF: Problems and Prospectives.

African swine fever (ASF) is a highly contagious viral disease affecting pigs, with mortality rates a primary focus as they can reach up to 100%. The widespread and colossal economic losses from ASF have impacts on the development of animal husbandry practices in most countries within Africa, Asia, and Europe. Currently, a variety of approaches toward the development of vaccines against ASF are being employed.

Assessment and Antibiotic Resistance Profiling in Species Isolated from Wild Birds Captured in Reserve, Romania.

Antimicrobial and multidrug-resistant bacteria are a major problem worldwide and, consequently, the surveillance of antibiotic-resistant bacteria and assessment of the dissemination routes are essential. We hypothesized that migratory birds, coming from various environments, would carry more numerous strains than sedentary species, with increased risk to be passed to their contacts or environment in habitats they transit or nest in. Similarly, we presumed that strains from migratory birds will show multidrug resistance.

Bacillus pumilus ribonuclease rescues mice infected by double-stranded RNA-containing reovirus serotype 1.

Reoviruses (respiratory enteric orphan viruses) are nonenveloped viruses with segmented dsRNA genome. Viruses in the family Reoviridae are quite stable in the environment. Recently, they have been identified with various pathologies and physiologic dysfunctions in a wide range of organs and tissues, including the hepatobiliary system, the myocardium, lungs, and endocrine tissues.
