Infections caused by the intestinal ciliate Neobalantidium coli are asymptomatic in most hosts. In humans and captive African great apes clinical infections occasionally occur, manifested mainly by dysentery; however, factors responsible for development of clinical balantidiasis have not been fully clarified. We studied the effect of dietary starch on the intensities of infection by N. coli in two groups of captive chimpanzees. Adult chimpanzees infected by N. coli from the Hodonín Zoo and from the Brno Zoo, Czech Republic, were fed with a high starch diet (HSD) (average 14.7% of starch) for 14 days, followed by a five-day transition period and subsequently with a period of low starch diet (LoSD) (average 0.1% of starch) for another 14 days. We collected fecal samples during the last seven days of HSD and LoSD and fixed them in 10% formalin. We quantified trophozoites of N. coli using the FLOTAC method. The numbers of N. coli trophozoites were higher during the HSD (mean ± SD: 49.0±134.7) than during the LoSD (3.5±6.8). A generalized linear mixed-effects model revealed significantly lower numbers of the N. coli trophozoites in the feces during the LoSD period in comparison to the HSD period (treatment contrast LoSD vs. HSD: 2.7±0.06 (SE), z = 47.7; p≪0.001). We conclude that our data provide a first indication that starch-rich diet might be responsible for high intensities of infection of N. coli in captive individuals and might predispose them for clinically manifested balantidiasis. We discuss the potential nutritional modifications to host diets that can be implemented in part to control N. coli infections. © 2013 Schovancová et al.

One of a ways of a material utilization of a rubber waste originated from recycling of tires is its inclusion into polymeric materials. The paper describes chosen mechanical properties of an epoxy adhesive and polyurethane filled with the waste rubber. The waste rubber was gained as one of outputs of a recycling line of a firm Gumoeko, Ltd. The filler presence influences resultant mechanical properties and decreases a price of gained materials. Defining of mechanical properties enables to specify possible application areas. © (2014) Trans Tech Publications, Switzerland.

The common bean is cultivated in all regions of Kosovo, along with maize or as single crop. Planting area with common beans is 7505 ha, with an average yield of 0.9 t/ha, while the annual consumption per capita is 11.53 kg. The amount and distribution of bean landraces (Phaseolus vulgaris L.) in Kosovo, as well as their respective traits remain poorly understood. The aim of this research was the characterization and evaluation of genetic and phenotypic diversity among common bean landraces. Characterization and evaluation of bean genotypes was done according with IBPGR descriptor. The experimental design was a random complete block design (RCBD), with three replications. The main investigated phenotypic parameters were: days to flowering (G-DF) 19.04%, days to maturity (G-DM) 6.87%, days flowering to days of maturity (DF-DM) 18,84%. Pod traits diversity and variability between genotypes were estimated by: pod length (PL) 73.05% and pod width (PW) 15.5%. Significant differences for diversity and variability, were found among different landraces. From our findings we can conclude that there is a high diversity and variability among common bean landraces in Kosovo.

Potato (Solanum tuberosum L.) plant is widespread with high skill production and multilateral use. It's one of the most important agricultural crops in the world, which occupy fourth place in total annual production at global level (about 300 million tons per year) after wheat, maize and rice. Chemical composition of potato tubers vary greatly depending on the cultivar genetic potential, applied agrotechniques and cultivation conditions, respectively. The aim of this research was to determine the mineral composition of four processing potato cultivars ('Agria', 'Mustang', 'Sinora' and 'Marlen') on two different agro-ecological regions in Kosovo. Field experiments were completely randomized block with four replications. After harvesting by random method, samples of 5 kg tubers were taken from each cultivar and analyzed in the laboratory of Kosovo Agriculture Institute (KAI). Mineral substances where determined by combustion at 700°C for one hour. Flame photometric method for Ca, K and Na, ASS method for Fe and Mg, while spectrophotometry was used for P determination. Statistically significant differences were found regarding the influence of cultivar, location and their interaction. The highest content of mineral matters (ash) was found in cultivar 'Agria' and the lowest one in cultivar 'Sinora'.
