The adverse long-term events in first-generation drug-eluting stents were associated with chronic inflammatory response to the polymer. As an alternative, stents with biodegradable polymers emerged, whose effects on the vascular response are not yet fully known. Our objectives were to study the adventitial response to the stent implantation and the role of the polymeric vehicle. A histological (Haematoxylin-Eosin, Verhoeff van Gieson) and immunohistochemical (von Willebrand factor, alpha-smooth muscle actin) analysis were performed on resin-embedded arterial sections...

The piglet birth weight and its variance within a litter may be considered important traits that influence pig productivity in the first and later stages of rearing. 222 piglets were evaluated from the moment they were born until weaning, and then as fattening pigs until the end of the fattening (n = 207) in three birth weight groups. Negative consequences of an excessively low piglet birth weight were observed, including higher mortality until weaning and a lower average daily gain during suckling. The correlation coefficients between the piglet birth weight and the remaining...

There are limited data available in the literature about the frequency and distribution of endocarditis in suckling and weaned piglets. The goal of this study was to investigate the frequency and distribution of lesions from cases of spontaneous valvular endocarditis in young piglets and to determine the bacterial agents involved in those lesions. Valvular endocarditis lesions in suckling piglets were detected in 21/454 cases (4.62%) and in 20/306 cases (6.53%) in weaned piglets. Streptococci were the dominant bacterial species isolated...

Occurrence of mycotoxins in complete poultry feeds in the Czech Republic - Multiannual survey (2013-2018)Original Paper

Vet Med - Czech, 2020, 65(11):487-494 | DOI: 10.17221/109/2020-VETMED  

To assess the contamination and potential health risks for poultry, we investigated concentrations of selected mycotoxins in complete feeds sampled within the period of 2013-2018 in the Czech Republic. Broiler feeds, feeds for laying hens, chickens and/or other poultry species were investigated by ELISA methods or chromatography. Our results demonstrated that unlike other mycotoxins, (such as aflatoxins, ochratoxin A or zearalenone), deoxynivalenol (DON) may represent a potential threat. The prevalence of this mycotoxin in all the feed categories was very high,...

Chemical analyses and evaluation of the anthelmintic effects of Origanum majorana essential oil, in vitro and in vivo studiesOriginal Paper

Because of the development of resistance in helminths against major anthelmintic drugs, the search for alternatives is necessary. Medicinal plants are being studied as an alternative source of anthelmintics against gastrointestinal nematodes. The objective of this study is to analyse the chemical composition and evaluate the anthelmintic efficacy of Origanum majorana essential oil. The determination of the chemical composition by gas chromatography/mass chromatography (GC/MS) revealed that the essential oil was dominated by terpenoids,...

Systemic mucormycosis caused by Lichtheimia ramosa in a pregnant cowCase Report

Vet Med - Czech, 2020, 65(11):506-510 | DOI: 10.17221/8/2020-VETMED  

Mucormycosis is a life-threatening fungal disease caused by opportunistic pathogens present in the environment. This report presents a case of a Lichtheimia ramosa infection that manifested as characteristic lesions in various visceral organs of a pregnant cow in Korea. The post-mortem examination revealed the cause of death to be mucormycosis. The fungi isolated from the liver were found to be Lichtheimia spp. Analysis of the fungi using Internal Transcribed Spacer gene sequencing facilitated the identification of Lichtheimia...
