Abstract In Poland, African swine fever (ASF) emerged in February 2014; by August 2015, the virus had been detected >130 wild boar and pigs 3 backyard holdings. We evaluated ASF spread Poland during these 18 months. Phylogenetic analysis indicated repeated incursions of genetically distinct viruses genotype II; number cases positively correlated density; disease was very slow. More were reported summer than autumn. The 18-month prevalence areas under various animal movement restrictions...

In this study, 120 silage samples collected in 2015 from farms Poland were analysed by a multimycotoxin method based on liquid chromatography coupled with tandem mass spectrometry. The study included toxins which are regulated within the European Union (aflatoxins, deoxynivalenol, fumonisins, T-2/HT-2 toxins, ochratoxin A and zearalenone) non-regulated mycotoxins (enniatins, beauvericin, 8-ketotrichothecenes, sterigmatocystin, zearalenone derivatives). All positive for at least one...

Antimicrobial resistance (AMR) is one of the most important global health concerns; therefore, identification AMR reservoirs and vectors essential. Attention should be paid to recognition potential hazards associated with wildlife as this field still seems incompletely explored. In context, role free-living birds carriers noteworthy. Therefore, we applied methods used in monitoring, supplemented by colistin screening, investigate status Escherichia coli from coming natural habitats rescue...

In this study, we investigated the clinical response, viral shedding, transmissibility, pathologic lesions, and tropism of HPAIV Gs/Gd H5N8 subtype (clade 2.3.4.4b), following experimental infection three groups captive mallards (Anas platyrhynchos): (i) fully susceptible, (ii) pre-exposed to low pathogenic avian influenza virus (LPAIV) H5N1 subtype, (iii) LPAIV H3N8 subtype. Infection naïve with resulted in ~60% mortality, neurological signs, abundant transmission contact ducks, who also...

Abstract To improve understanding of the pathobiology highly pathogenic avian influenza virus (HPAIV) infections in wild birds, pathogenicity and transmissibility HPAIV H5N8 subtype clade 2.3.4.4b was evaluated ~ 8-week-old herring gulls ( Larus argentatus ) divided into 3 groups: naïve birds (group A), previously exposed to low (LPAIV) H5N1 B) LPAIV H13N6 C). The virulent for gulls, that showed early morbidity, high mortality, a broad spectrum clinical signs, including violent neurological...

Enteric diseases are an important health problem for the intensive poultry industry, resulting in considerable economic losses. Apart from such microbiological agents associated with enteritis as bacteria and parasites, a lot of research has been recently conducted on viral origin enteric diseases. However, viruses have identified intestinal tract not only diseased but also healthy poultry, so their role is still unclear. The present study aimed at determination prevalence four viruses,...

Leptospira spp. infect humans and a wide range of domestic wild animals, but certain species such as small rodents red foxes (Vulpes vulpes) play particular role reservoirs transmission leptospirosis they easily adapt to many habitats including human environments. To investigate the significance in epidemiology Poland, seroprevalence survey was conducted. During 2014–2015 hunting season, blood samples 2134 originating from central-eastern part Poland were collected. Serum tested by...

African swine fever (ASF) was introduced to Poland in 2014. Despite the implementation of preventive actions focused on reduction wild boar populations and introduction biosecurity rules domestic pig farms, disease has been continuously spreading new areas.
