A cross-sectional retrospective study of SARS-CoV-2 seroprevalence in domestic cats, dogs and rabbits in Poland.

Background: Coronaviruses (CoVs) have long been known to cause infection in domestic and free-living birds and mammals including humans. The zoonotic origin of SARS-CoV-2 and the biological properties of CoVs, including ability to cross interspecies barriers, enable its emergence in populations of various animals, including companion animals (cats, dogs, rabbits) an area requiring further study. To date, several cases of cats and dogs positive for SARS-CoV-2 and/or specific antibodies have been described.

Distribution of , and in the Diaphragms and and in the Tongues of Experimentally Infected Pigs.

There is little or even no data in the global literature on the distribution of different species of in the individual parts of the diaphragms and tongues in infected pigs. This is of particular importance from the food safety point of view and for the conduct of routine testing of pig carcasses for as well as epidemiological surveys. Therefore, the aim of the present study was to evaluate the distribution of , and ML in various parts of the diaphragm (the pillars, costal, and sternal part) and the distribution of encapsulated species of ( and ) in various parts of the tongues (the tip, body, and root) of experimentally infected pigs.

African Swine Fever Virus as a Difficult Opponent in the Fight for a Vaccine-Current Data.

Prevention and control of African swine fever virus (ASFV) in Europe, Asia, and Africa seem to be extremely difficult in view of the ease with which it spreads, its high resistance to environmental conditions, and the many obstacles related to the introduction of effective specific immunoprophylaxis. Biological properties of ASFV indicate that the African swine fever (ASF) pandemic will continue to develop and that only the implementation of an effective and safe vaccine will ensure a reduction in the spread of ASFV. At present, vaccines against ASF are not available.
