Opis:
The striped field mouse, Apodemus agrarius, is one of the most abundant species among small rodents in Poland. It occurs commonly across the whole country inhabiting diverse ecological niches as meadows, farmlands, enclaves of natural habitats in cities. Wide range of ecological tolerance of this species makes it often the host, reservoir and vector of many pathogens: viruses, bacteria, protozoa, helminths and arthropods. The aim of the present study was to carry out a qualitative and quantitative analysis of the fleas community and intestinal tapeworms of A. agrarius in suburban environment of Lublin (eastern Poland). In studied population three species of Siphonaptera class i.e. Ctenophthalmus agyrtes, Nosopsyllus fasciatus, Hystrichopsylla talpae and one intestine Cestoda species Hymenolepis diminuta were identified. The results of our researches confirmed role of A. agrarius as the reservoir for tapeworms and host for fleas in urban environment. High level of the prevalence of fleas and tapeworms in rodents indicates the significant degree of contamination and can cause an epidemiological threat for human’s health.

Opis:
Introduction and objective. Expansion into new areas and the great epidemiological significance of the D. reticulatus tick in Europe prompts investigations of its ethology. Therefore, the locomotor activity of D. reticulatus adult stages in an optimal habitat during the spring and autumn activity periods was analysed. Materials and method. Marked D. reticulatus adults were placed at the central point of each experimental plot. At regular time intervals, specimens attached to the cloth used in the flagging method were collected, and the distance covered by the ticks was measured. In each collection round, the temperature and humidity level in the habitat was also measured. Results. Within 7 weeks, adult D. reticulatus ticks can cover an average distance of 60.71±44 cm. The locomotor activity of adult stages is greater during the spring than the autumn activity period. Questing, females cover a greater distance (66.35±100 cm) than male ticks (54.85±45 cm). Adult stages are characterised by greater aggressiveness 24 hours after being released, i.e. 30% of females and 19% of males attempt to attach to host skin. The locomotor activity in adult ticks depends on the humidity of the habitat (Z=-1.198; p=0.050). The temperature does not affect tick walking. Conclusions. Given the low rates of horizontal locomotion of adult D. reticulatus ticks, the prevalence of the species in nature is determined by the presence of their hosts and humidity conditions ensuring their further development and survival. The dependence of D. reticulatus locomotor activity and aggressiveness on the humidity level implies an increased risk of host attacks in locations and periods that offer favourable humidity conditions for this species.

Opis:
Occurrence of co-infections with various pathogens in ixodid ticks creates a risk of increased severity of tick-borne diseases in humans and animals exposed to bite of the ticks carrying multiple pathogens. Accordingly, co-infections in ticks were subject of numerous analyses, but almost exclusively with regard to Ixodes ricinus complex whereas potential tick vectors belonging to other genera were much less studied. Taking into consideration the role of Dermacentor reticulatus in the transmission of various pathogens, we carried out for the first time the comprehensive statistical analysis of co-infections occurring in this tick species. An attempt was made to determine the significance of the associations between 6 different pathogens occurring in D. reticulatus (Tick-borne encephalitis virus = TBEV, Anaplasma phagocytophilum, Rickettsia raoultii, Borrelia burgdorferi s. l., Babesia spp., Toxoplasma gondii), using 2 statistical methods: determination of Odds Ratios (ORs) and the Fisher’s exact test. 634 questing Dermacentor reticulatus ticks (370 females and 264 males) were collected in 2011–2013 by flagging the lower vegetation in 3 localities in the area of Łęczyńsko-Włodawskie Lakeland, situated in the Lublin region of eastern Poland. The presence of individual pathogens was detected by PCR. Ticks were infected most often with Rickettsia raoultii (43.8%), less with TBEV (8.5%), and much less with Babesia spp., Toxoplasma gondii, Borrelia burgdorferi s.l., and Anaplasma phagocytophilum (2.5%, 2.1%, 1.6% and 1.1%, respectively). The locality-dependent variability proved to be significant for TBEV (c2=11.063; P=0.004) and Toxoplasma gondii (c2=11.298; P=0.0035), but not for other pathogens. Two hundred seventy (42.6%) of the examined ticks were infected only with a single pathogen, and 54 (8.5%) showed the presence of dual co-infections, each with 2 pathogens. The most common were dual infections with participation of Rickettsia raoultii (7.41%); next, those with participation of the TBEV (5.21%), Toxoplasma gondii (1.58%), Borrelia burgdorferi s.l. (1.26%), Anaplasma phagocytophilum (0.95%), and Babesia spp. (0.63%). On the total number of 15 possible associations, in 9 cases co-infections occurred whereas in 6 cases they were not detected. The most noteworthy were positive co-infections with the participation of TBEV, which proved to be weakly significant (0.05

Treatment of cyanuric chloride with chiral amines or esters of chiral amino acids gave chiral 2,4-dichloro-6-alkylamino-1,3,5-triazines (2-5) in 49-69% yield, which were found useful as coupling reagents. Enantioselective activation and enantioselective aminolysis in the presence of 2-5 was observed.

Opis:
The cytotoxicity of chitosan with polyvinox (PCH) and crosslinked chitosan (CH) was studied and analyzed. Cell viability was determined by thiazolyl blue formazan (MTT) assay and cell morphology observations were carried out during cell culturing and MTT tests. Crosslinked chitosan was used as a protective foil (scaffold) for skin wounds. Studies in vitro and the other obtained in this work results prove that the studied materials CH and PCH do not cause cytotoxic activity to Balb 3T3 mouse fibroblasts. CH and PCH are promising biomaterials with prospective application as wound healing dressings.
