Nosema ceranae and queen age influence the reproduction and productivity of the honey bee colony
(Taylor & Francis Ltd, Abingdon, 2014)
The strength of the honey bee colony and the quality concerning brood production, number of worker bees and honey yield depend substantially upon the characteristics of the queen. Reproductive and productive capacities of ...
Honey bee colony winter loss rates for 35 countries participating in the COLOSS survey for winter 2018–2019, and the effects of a new queen on the risk of colony winter loss
(Taylor and Francis Ltd., 2020)
This article presents managed honey bee colony loss rates over winter 2018/19 resulting from using the standardised COLOSS questionnaire in 35 countries (31 in Europe). In total, 28,629 beekeepers supplying valid loss data ...
Coexistence of genetically different Varroa destructor in Apis mellifera colonies
(Springer, Dordrecht, 2019)
The aim of this study was to investigate the genetic diversity of Varroa destructor parasitizing Apis mellifera colonies and to test for possible host-parasite association at the mitochondrial DNA (mtDNA) level. Six A. ...
The effect of diet types on some quality characteristics of artificially reared Apis mellifera queens
(Taylor & Francis Ltd, Abingdon, 2020)
The influence of various diets on the quality of Apis mellifera queens was assessed. Colonies intended for queen cell production were assigned to four groups fed on (1) sugar-only, (2) mix of sugar, honey and fresh pollen, ...
Effects of Agaricus bisporus Mushroom Extract on Honey Bees Infected with Nosema ceranae
(MDPI, 2021)
Agaricus bisporus water crude extract was tested on honey bees for the first time. The first part of the cage experiment was set for selecting one concentration of the A. bisporus extract. Concentration of 200 µg/g was ...
Seasonal Prevalence of Shiga Toxin-Producing Escherichia coli on Pork Carcasses for Three Steps of the Harvest Process at Two Commercial Processing Plants in the United States
(American Society for Microbiology, 2020)
Shiga toxin-producing Escherichia coli (STEC) is a foodborne pathogen that has a significant impact on public health, with strains possessing the attachment factor intimin referred to as enterohemorrhagic E. coli (EHEC) ...
Quantitative PCR assessment of Lotmaria passim in Apis mellifera colonies co-infected naturally with Nosema ceranae
(Academic Press Inc Elsevier Science, San Diego, 2018)
A recently described trypanosomatid species Lotmaria passim and the microsporidium Nosema ceranae infect the honey bee (Apis mellifera), but the interspecific dynamic of these two common gut parasites is unknown. In this ...
Inhibition of Salmonella by thyme essential oil and its effect on microbiological and sensory properties of minced pork meat packaged under vacuum and modified atmosphere
(Elsevier, Amsterdam, 2017)
The antibacterial activity of thyme essential oil (TEO) was evaluated against four serovars of Salmonella (S. Enteritidis, S. Typhimurium, S. Montevideo and S. Infantis), experimentally inoculated (10(6) CFU/g) in minced ...
Estimation of honey bee colony infection with Nosema ceranae and Varroa destructor using fluorescence spectroscopy in combination with differential scanning calorimetry of honey samples
(Taylor and Francis, 2021)
In this preliminary study, we applied the Multivariate Curve Resolution- Alternating Least Squares (MCR-ALS) method to analyze the excitation-emission matrices of multifloral honey samples, combined with differential ...
Oxidative Stress, Endoparasite Prevalence and Social Immunity in Bee Colonies Kept Traditionally vs. Those Kept for Commercial Purposes
(MDPI, 2020)
Commercially and traditionally managed bees were compared for oxidative stress (superoxide dismutase (SOD), catalase (CAT), glutathione S-transferase (GST) and malondialdehyde (MDA)), the prevalence of parasites (<i>Lotmaria ...
