Assessing tropism and genetic traits of carp oedema virus isolates to enhance detection strategies
2024
Adamkowska Natalia | Kiełpińska Jolanta | Bergmann Sven Michael
Carp oedema virus (CEV) is a relatively understudied poxvirus. It exhibits an affinity for gill and skin epithelial cells. Investigations were conducted into selected aspects of CEV biology, with a focus on determining cell and tissue tropism of CEV, acquiring gene sequences and updating CEV tests in fish tissues.

2024
Patyra Ewelina | Kwiatek Krzysztof
The article presents a rapid and simple analytical procedure for determination of four sulfonamides (sulfadiazine, sulfamerazine, sulfamethazine and sulfamethoxazole), trimethoprim, tylosin and amoxicillin in animal medicated feed.
Afficher plus [+] Moins [-]Tissue expression of porcine transient receptor potential mucolipin protein channels and their differential responses to porcine reproductive and respiratory syndrome virus infection in vitro
2024
Xia Zhiqiang | Long Denggao | Hong Xinyi | Lan Ying | Xie Lixia
Porcine reproductive and respiratory syndrome virus (PRRSV) infection results in a serious disease, posing a huge economic threat to the global swine industry. The transient receptor potential mucolipin proteins (TRPMLs) have been shown to be strongly associated with virus infection and other physiological processes in humans, but their tissue distribution and responses to PRRSV in pigs remain unknown.

2024
Bergmann Sven Michael | Wang Yingying | Li Yingying | Wang Qing | Klafack Sandro | Jin Yeonhwa | Hofmann Arndt Christian | Kielpinska Jolanta | Becker Anna Maria | Zeng Weiwei
Herpesviruses are common agents in animals of the aquatic environment. They infect many species of fish but only lead to disease in one or two species. Nevertheless, infected fish without clinical symptoms can actively transfer infectious agents to disease-susceptible species. The aim of the study was to identify and prove the natural presence of different herpesviruses.

2024
Jagódka Dariusz | Kaczorek-Łukowska Edyta | Socha Piotr Andrzej
How bacterial infections of the reproductive tract cause infertility and the correlation between the health status of female dogs and the presence of Mycoplasma canis (M. canis) in the vagina are still unclear. The aim of this study was to determine the M. canis population in the vagina of breeding bitches and to correlate this microbial population with some fertility outcomes.
Afficher plus [+] Moins [-]The effect of coffee husks used as pellet bedding material on the intestinal barrier, immune-related gene expression and microbiota composition in the broiler chicken caecum
2024
Biesek Jakub | Dunisławska Aleksandra | Kozdruń Wojciech
Using coffee husks as waste material for bedding contributes to sustainable development. A sustainable choice of bedding has also, however, to be a safe choice for poultry. The study analysed immune-related gene expression in the intestinal mucosa and indicator bacteria in caecal content collected from broiler chickens bedded on material with coffee husk addition.

2024
Itoh Harumichi | Inoue Hajime | Itamoto Takuya | Tani Kenji | Sunahara Hiroshi | Nemoto Yuki | Nakaichi Munekazu | Iseri Toshie | Itamoto Kazuhito
Perfusion index (PI) is used as assessment of epidural anaesthesia efficacy in human medicine, but its usefulness in dogs is unknown. The aim of this study was to evaluate the usefulness of PI in determining epidural anaesthesia effectiveness.

2024
Lisiecka Urszula | Brodzki Piotr | Śmiech Anna | Michalak Katarzyna | Winiarczyk Stanisław | Żylińska Beata | Adaszek Łukasz
The main adaptive immune cells are T and B lymphocytes and they play key roles in the induction of immune responses against canine mammary tumours. Investigating these cell subpopulations may lead to more precise diagnosis of these malignancies.

2024
Gajda Anna | Szymanek-Bany Iwona | Nowacka-Kozak Ewelina | Gbylik-Sikorska Małgorzata
Chicken bones, a by-product of the poultry industry, can directly or indirectly enter the food chain. Bone meal and bone products could be sources of many contaminants. Considering the wide range of uses made of bones in the culinary and food industries, this material needs to be safe and antibiotic residue–free. To determine if such is the case, the concentration of doxycycline in chicken bones was investigated, this antimicrobial being one of the most commonly used in poultry production.
