An outbreak of koi herpesvirus (KHV) infection associated with high mortality of common and koi carp was recorded in the USA and Israel in 1998. At present, this disease is viewed as one of the most significant factors that can adversely affect common and koi carp breeds. The disease has spread worldwide including European countries neighbouring with the Czech Republic (CR), i.e. Germany, Poland, and Austria. To monitor the situation in the CR, samples were collected from a total of 138 common and koi carps in seven and eight locations in CR respectively, and were examined between 2005 and 2006. Locations owned by the major producers of common and koi carp were selected with respect of potential occurrence of the KHV virus. No records of increased mortality and morbidity were noticed there. Preferentially carps with non-specific symptoms of disease were sampled, often with isolated skin erosions. To obtain detailed picture about health condition of examined fish the bacteriological and haematological examinations were accomplished. The next part of the examined samples were carp and koi carp for export from professional breeders, imported koi carp and fish from breeds with increased mortality (45 and 21 fish in 2005 and 2006, respectively) The only virological testing was done in this case. The culture and PCR method, according to Gilad et al. (2002) showed negative results for virus KHV in all years. Retrospective investigation by PCR method according to Bercovier et al. (2005) showed positivity in five locations in 2005. In 2006, KHV virus was not detected in any of the selected locations. The aim of our study was to find out the presence/absence of KHV in selected locations and potential correlation of virological, bacteriological and haematological findings. The results of first testing for presence of koi herpesvirus indicates the necessity of regular KHV monitoring in the Czech Republic in the next period.

AbstractObjectiveThe prevalence of child overweight in the Czech Republic is substantially lower than that in the USA. The objective of the present pilot study was to explore dietary intakes, frequency of dining in fast-food establishments, and the amount and intensity of physical activity between a sample of American and Czech children.DesignA cross-sectional correlational pilot study.SettingFour public schools in the USA and four public schools in the Czech Republic.SubjectsNinety-five Czech and forty-four American 4–6th graders from urban public schools participated in the study. Dietary intake and number of fast-food visits were evaluated using two multiple-pass 24 h recalls. Physical activity was measured using the modified Self-Administered Physical Activity Checklist.ResultsAmerican children (mean age 10·8 (se 0·2) years) consumed more energy and fat, less fruits and vegetables, more soft drinks, and visited fast-food establishments more often than Czech children (mean age 11·0 (se 0·1) years). Although no differences were found in vigorous activity by nationality, Czech children spent significantly more time in moderate physical activities than American children.ConclusionsDespite the influx of some negative Western dietary trends into the country, Czech children had a healthier diet and were more physically active than American children. Further research is warranted to determine whether the same differences in dietary intakes, physical activity and fast-food visits exist between nationally representative samples of American and Czech children.

Abstract The processing of ombrographic data from 29 meteorological stations of the Czech Hydrometeorological Institute (CHMI), according to the terms of the Universal Soil Loss Equation for calculating long term loss of soil through water erosion, erosion hazard rains and their occurrence have been selected, with their relative amount and erosiveness - R-Factors determined for each month and years. By comparing the value of the time division of the R-Factor in the area of the Czech Republic and in selected areas of the USA it has been demonstrated that this division may be applied in the conditions of the Czech Republic. For the Czech Republic it is recommended to use the average value R = 40 based on the original evaluation.

Alder decline along watercourses is one of the marked manifestations of tree decline in the Czech Republic. Local decline of alder trees is documented in the Czech Republic for about 15 years. The aim of this paper is to evaluate causes of alder decline and assess health conditions of other species of riparian stands at 2 localities on the medium reach of the Lužnice River. Effects were studied of abiotic and biotic stressors on the health condition of tree species. No fungal pathogen was found in tissues of declining alders which would be present in all trees and which could be considered to be the main causal agent of the decline. Even an occurrence of the causal agent of alder decline named alder-Phytophthora has not been proved. Tree-ring analyses demonstrated decreasing trends of an increment in alders; however, an abiotic or biotic factor showing direct effects on the fluctuation of tree ring dimensions has not been positively determined. A marked role in the alder decline is demonstrated particularly by abiotic factors accompanied by the secondary activation of some pathogens. Generally, the phenomenon can be named as polyetiologic decline.

From March to November 2010, a total of 68 samples of blood from 41 hunting and working dogs that never left the Czech Republic were examined. Some dogs were sampled repeatedly. Blood samples were examined by polymerase chain reaction for the presence of DNA of piroplasms with negative results. Specific IgG antibodies against Babesia canis were detected by indirect immunofluorescence test, and five dogs (12.21%) were seropositive. Titres ranged from 50 to 200. One dog was positive in two samplings within 3 months. The highest number of positive samples was taken in June. The results of this study suggest a likely contact of the examined dogs with the parasite; although in 2005, a total of 340 adult unfed Dermacentor reticulatus ticks in 34 pools screened by PCR for babesiae were negative.

The results of a survey large Czech manufacturing companies are presented which shows the current levels of investment in advanced manufacturing technology (AMT), the techniques and criteria used to assess AMT capital projects, and attitudes to the need for further investment. Comparisons are made with the results of earlier identical surveys in the UK and the USA. The comparisons reveal numerous statistically significant differences. The current levels of AMT investment in the Czech Republic are relatively low, the techniques used for evaluation relatively unsophisticated, the investment criteria used are more short term, and there is less concern about the need for AMT.

Investors' decisions are largely influenced by the riskiness of the country. Several different approaches are available to calculate this risk, but even so, the values set by Damodaran are usually used, even for non-US states. The aim of the paper is to propose a methodology for creating a risk premium in the environment of the Czech Republic and then compare it with Damodaran [1]. Methods applicable in the Czech Republic and Damodaran methods are used, then these methods are compared. For Czech as well as foreign investors, the easiest way to obtain a risk premium is to use the company’s investment rating. In the case of determining the risk premium of the Czech Republic, the easiest method is the CRP (country risk premiums) model. If the country’s market does not have a long history or does not have such a developed capital market, it is recommended to apply data from the US capital market. However, there are significant differences in the economy between Europe and the USA, so the data of an European country such as Germany, which has historical risk premium calculations, should be used.

During the period 2010–2017 we monitored 17 346 183 laying hens, 887 994 167 broiler chickens and 919 843 turkeys slaughtered at slaughterhouses in the Czech Republic. In cooperation with the State Veterinary Administration, we recorded findings detected in slaughtered birds within the post mortem veterinary inspection. We analysed the total number of patho-anatomical findings (of intravital origin) and the number of findings divided into acute, chronic and traumatic diseases. In hens, the total ratio of the number of patho-anatomical intravital findings to the number of slaughtered birds (index) was found to be 0.378. This index of the incidence of patho-anatomical findings in hens was higher (P < 0.001) than that found in broilers (0.016) and turkeys (0.101). The prevailing findings in hens were chronic changes (26.32%), followed by acute changes (5.29%), but also notable were traumatic changes (3.90%). Compared to the findings in broilers which were divided into chronic (0.34%), acute (0.10%) and traumatic diseases (0.02%) and turkey findings which were broken down into chronic (7.60%), acute (0.16%) and traumatic diseases (0.33%), the findings of acute, chronic and traumatic diseases were higher (P < 0.001) in hens than in broilers and turkeys. These findings show that the health condition and hence the welfare of laying hens as reflected in the patho-anatomical findings during the veterinary inspection of slaughtered birds is significantly worse than the health condition of broilers and turkeys. This demonstrates the need for increased care for laying hens both on farms and in transit to the slaughterhouse.
