Conventional and State-of-the-Art Detection Methods of Bovine Spongiform Encephalopathy (BSE)
Olech, Monika (MDPI, 2023)Bovine spongiform encephalopathy (BSE) is a fatal neurodegenerative disease that belongs to a group of diseases known as transmissible spongiform encephalopathies (TSEs). It is believed that the infectious agent responsible ... -
First molecular characterization of small ruminant Lentiviruses detected in Romania
Olech, Monika; Hodor, Dragos; Toma, Corina; Negoescu, Andrada; Taulescu, Marian (MDPI, 2023)Small ruminant lentiviruses (SRLVs) are a group of retroviruses that cause multisystem chronic diseases in goats and sheep and lead to production losses in these animals, negatively affecting animal health and welfare. ... -
Genetic Diversity of the LTR Region of Polish SRLVs and Its Impact on the Transcriptional Activity of Viral Promoters
Olech, Monika; Kuźmak, Jacek (MDPI, 2023)A long terminal repeat (LTR) plays an indispensable role in small ruminant lentivirus (SRLV) gene expression. In this study, we present the LTR sequence of Polish SRLVs representing different subtypes, and analyzed their ... -
Molecular characterization of porcine epidemic diarrhoea virus (PEDV) in Poland reveals the presence of swine enteric coronavirus (SeCoV) sequence in S gene
Antas, Marta; Olech, Monika; Szczotka-Bochniarz, Anna (2021)Porcine epidemic diarrhoea (PED) is a highly contagious enteric viral disease of pigs with a high morbidity and mortality rate, which ultimately results in huge economic losses in the pig production sector. The etiological ... -
Molecular Characterization of Small Ruminant Lentiviruses in Polish Mixed Flocks Supports Evidence of Cross Species Transmission, Dual Infection, a Recombination Event, and Reveals the Existence of New Subtypes within Group A
Olech, Monika; Kuźmak, Jacek (MDPI, 2021)Small ruminant lentiviruses (SRLVs) are a group of highly divergent viruses responsible for global infection in sheep and goats. In a previous study we showed that SRLV strains found in mixed flocks in Poland belonged to ... -
Molecular Characterization of Small Ruminant Lentiviruses Isolated from Polish Goats with Arthritis
Olech, Monika; Kycko, Anna; Kuźmak, Jacek (MDPI, 2022)Previous studies revealed that the small ruminant lentivirus (SRLV) population in Poland is highly heterogeneous. All SRLVs detected from Polish sheep and goats so far have belonged to subtypes B1, B2, A1, A5, A12, A13, ... -
Mutations of p53 gene in canine sweat gland carcinomas probably associated with UV radiation
Jasik, Agnieszka; Kycko, Anna; Olech, Monika; Wyrostek, Krzysztof; Śmiech, Anna; Łopuszyński, Wojciech; Otrocka-Domagała, Iwona; Mikiewicz, Mateusz; Dolka, Izabella (National Veterinary Research Institute in Pulawy, 2021)Apocrine sweat gland carcinomas (ASGCs) are rare malignant skin tumours in dogs and humans. The literature published so far focuses mostly on the clinico-epidemiological aspect of these tumours, but little is known about ... -
Problemy w diagnostyce lentiwirusów małych przeżuwaczy (SRLV)
Olech, Monika (Krajowa Izba Lekarsko-Weterynaryjna, 2024)Small ruminant lentiviruses (SRLVs), it is a group, which include, maedi-visna virus(MVV), and caprine arthritis encephalitis virus (CAEV). They cause multisystemic,chronic infections and inflammatory lesions in the affected ... -
Quasispecies composition of small ruminant lentiviruses found in blood leukocytes and milk epithelial cells
Olech, Monika; Bomba, Arkadiusz; Kuźmak, Jacek (MDPI, 2021)Small ruminant lentiviruses (SRLVs) exist as populations of closely related genetic variants, known as quasispecies, within an individual host. The privileged way of SRLVs transmission in goats is through the ingestion of ... -
The genetic variability of small-ruminant lentiviruses and its impact on tropism, the development of diagnostic tests and vaccines and the effectiveness of control programmes
Olech, Monika (National Veterinary Research Institute in Pulawy; Poland, 2023)Introduction: Maedi-visna virus and caprine arthritis encephalitis virus are two closely related lentiviruses which causemultisystemic, progressive and persistent infection in goats and sheep. Because these viruses frequently ... -
Transcriptome Analysis for Genes Associated with Small Ruminant Lentiviruses Infection in Goats of Carpathian Breed
Olech, Monika; Ropka-Molik, Katarzyna; Szmatoła, Tomasz; Piórkowska, Katarzyna; Kuźmak, Jacek (MDPI, 2021)Small ruminant lentiviruses (SRLV) are economically important viral pathogens of sheep and goats. SRLV infection may interfere in the innate and adaptive immunity of the host, and genes associated with resistance or ...
