Influence of natural and climatic conditions on the distribution and forms of contagious agalactia in sheep in Bessarabia, Ukraine Texto completo
2022
Volodymyrovych Bohach Mykola | Igorovych Bolotin Vitaliy | Mykolaivych Bohach Denys | Piven Olha Tarasivna | Pyvovarova Iryna Victorivna
Contagious agalactia of ruminants is an endemic disease caused by Mycoplasma agalactiae in flicting significant losses on farms in deaths and forced slaughter of sick animals, abortions, births of sick young animals, and reduced milk and wool production. The aim of the study was to determine the influence of hydrometeorological conditions on the distribution and forms of contagious agalactia in sheep in Bessarabia, Ukraine.
Mostrar más [+] Menos [-]Antimicrobial resistance and virulence genes in staphylococci isolated from aviary capercaillies and free-living birds in south-eastern Poland Texto completo
2022
Sulikowska Magdalena | Marek Agnieszka | Jarosz Łukasz | Stępień-Pyśniak Dagmara | Urban-Chmiel Renata
The current study characterises Staphylococcus bacteria recovered from dead free-living birds and captive capercaillies kept in south-eastern Poland. The results provide novel information about the antimicrobial resistance phenotype/genotype and the virulence profile of these bacteria.

2022
Stojević Dora | Humski Andrea | Mikulić Marina | Dobranić Vesna | Reil Irena | Duvnjak Sanja | Benić Miroslav | Beck Relja | Cvetnić Željko
Escherichia coli is present in the normal intestinal flora but some strains can cause intestinal and extraintestinal diseases, and research on its presence in food of animal origin is in the interests of public health. This study was designed to characterise E. coli strains according to their origin, their carriage of virulence genes specific for certain pathogroups, and phylogenetic group affiliation.

2022
Chen Wanting | Tu Teng | Luo Yan | Yang Zexiao | Yao Xueping | Wu Xulong | Wang Yin
In May 2020, an outbreak of rabbit haemorrhagic disease 2 (RHD2) caused by the rabbit haemorrhagic disease virus 2 (RHDV2, GI.2) occurred in Sichuan, China. The acute onset and short disease course resulted in rabbit mortality as high as 42.86%. Currently, basic research on the aetiology and genetic characteristics of GI.2 is lacking in China.
Mostrar más [+] Menos [-]Seroprevalence and epidemiological risk factors for Kasba virus among sheep and goats in South Korea: a nationwide retrospective study Texto completo
2022
Hwang Jeong-Min | Ga Yun Ji | Yeh Jung-Yong
Kasba virus belongs to the Palyam serogroup of the Orbivirus genus and Reoviridae family. Kasba virus is the causative agent of many reproductive disorders in infected animals, which result in considerable economic losses, mainly in the cattle industry. The epidemiology of Kasba virus infection is poorly defined and remains unclear in South Korea.
Mostrar más [+] Menos [-]Determination of anti-phage antibodies in calf sera following application of Escherichia coli and Mannheimia haemolytica-specific bacteriophages Texto completo
2022
Urban-Chmiel Renata | Nowaczek Anna | Chmiel Paulina | Wawrzykowski Jacek | Pyzik Ewelina | Marek Agnieszka | Stępien-Pyśniak Dagmara | Alomari Mohammed M.M. | Dec Marta
The widespread occurrence of drug-resistant bacteria has increased interest in alternatives to antibiotics for combatting bacterial infections, among which bacteriophages play an important role. The ability of phage proteins to induce an anti-phage immune response can significantly limit the effectiveness of treatment, which was the basis for the study described in this article. The aim of the study was to assess the effects of bacteriophages on the induction of an anti-phage humoral response in calves.
Mostrar más [+] Menos [-]Expression of bovine leukaemia virus (BLV) gp51 protein in blood and milk cells of cows with leukosis Texto completo
2022
Szczotka Maria | Kuźmak Jacek
Bovine leukaemia virus (BLV) is the retroviral causative agent of enzootic bovine leukosis, the most common neoplastic disease of cattle and a serious problem worldwide. Its diagnosis is commonly by tests for antibodies recognising the p24 capsid protein and structural glycoprotein (gp) 51. With flow cytometry recently having come to veterinary immunology, applications for it may now include BLV. The study determined BLV gp51 expression in blood and milk lymphocytes of naturally infected cows by flow cytometry.
Mostrar más [+] Menos [-]Is serological monitoring a fit-for-purpose tool to assess the epidemiological situation of tuberculosis in the sylvatic species of European bison (Bison bonasus) in Poland? Texto completo
2022
Krzysiak Michał K. | Larska Magdalena | Zabost Anna | Didkowska Anna | Krajewska-Wędzina Monika | Anusz Krzysztof | Augustynowicz-Kopeć Ewa
Bovine tuberculosis is one of the most dangerous zoonotic diseases. Despite the near-complete elimination of the disease from cattle breeding in Poland achieved in 2009, its re-emergence is now observed. Globally, the number of human cases is underestimated and the importance of free-living animals as reservoirs of tuberculosis is growing. As a species highly susceptible to Mycobacterium tuberculosis complex infection, the European bison (Bison bonasus) has a role in the transmission of the disease in Poland. The purpose of the investigation was to assess the epidemiological situation of tuberculosis in Polish European bison serologically.
Mostrar más [+] Menos [-]Examination of immunogenic properties of recombinant antigens based on p22 protein from African swine fever virus Texto completo
2022
Díaz Carlos | Salát Jiří | Břínek Kolařová Dagmar | Celer Vladimír | Frébort Ivo
The single member of the Asfarviridae family is African swine fever virus (ASFV). This double-stranded DNA virus infects wild and farmed swine and loses the pig industry large sums of money. An inner envelope, capsid, and outer envelope are parts of the ASFV particle containing structural proteins playing different roles in the process of infection or host immune defence evasion. When expressed by the baculovirus system, the p22 protein from the inner envelope was found to induce partial protection against a virulent virus strain. This study aimed to express a part of this protein in a different system and evaluate its immunogenicity.

2022
Rola-Łuszczak Marzena | Materniak-Kornas Magdalena | Kubiś Piotr | Pluta Aneta | Smagacz Marlena | Kuźmak Jacek
Bovine immunodeficiency virus (BIV) is found worldwide in cattle under natural conditions. However, the effect of BIV infection on immune functions has not been fully characterised.
