However, sorting in the field generally means less overall sampling can be done in the allotted time. Placing samples under cold conditions has been the traditional way to extend the life of the organisms contained within them. In this work, we evaluated whether the addition of a centrifugation step extends the survival time of organisms post-sampling, thus providing more time for sorting. Three salad spinners were tested for their capacity to extract water from samples. Additional observations were made on the compaction of samples due to excessive centrifugation. We conclude that adding a short centrifugation step of 30 seconds prolongs the life of several freshwater invertebrate taxa, including Hydrachnidia, Nematoda and Ostracoda. Furthermore, when fixation of samples in the field is necessary, centrifugation reduces the amount of fixative to be added to the samples to reach a certain concentration. Fixed samples can also be centrifuged, which may be particularly relevant when sampling abroad as inflam-mable liquids are often prohibited on planes. In our experience, centrifuging fixed samples does not compromise the fixed organisms, or their genetic material.","PeriodicalId":7009,"journal":{"name":"Acta Biologica Hungarica","volume":"27 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"75737098","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to the fact that the impact of RHDV on the host organism, and more precisely, its influence on the immune system, is crucial for the spread of this infection in rabbits, it is very important to understand the role of the immune system components in the course of infection with this virus. The aim of the study was to present innate and adaptive immune response to three strains (V411, 1092V, Wika) of the Lagovirus europaeus GI.1 (RHDV) identified at different times. Twelve indices were examined for the innate immune response and nine for the adaptive response. The results indicate that PMN cells (polymorphonuclear cells, neutrophils) play an important role in the response to this infection and give new insights into the function of CD4+ Th and CD8+ Tc lymphocytes. The most immunogenic was the Wika strain from 1996.","PeriodicalId":7009,"journal":{"name":"Acta Biologica Hungarica","volume":"2 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74526136","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

They are typically found on the gills, skin and fins of fish. The aim of this study was to evaluate the prevalence and mean intensity of Trichodina sp. in freshwater fish from cyprinid aquaculture facilities in Macedonia. This study was carried out by seasons, in a period of three years. A total of 578 specimens of common carp (Cyprinus carpio, Linnaeus 1758), 76 specimens of grass carp (Ctenopharyngodon idella, Valenciennes 1844), 47 specimens of silver carp (Hypophthalmichthys molitrix, Valenciennes, 1844) and 53 specimens of bighead carp (Hypophthalmichthys nobilis, Richardson, 1845) from the most significant and larger cyprinid aquaculture facilities in Macedonia, including fish farms and reservoirs, were examined for parasitological investigations. Infestation with Trichodina sp. was found in 206 specimens of common carp in all aquaculture facilities examined, in all seasons, as well as, in 9 specimens of grass carp from two fish farms, only in autumn season. Total, the prevalence with Trichodina sp. was 11.84% (grass carp) and 35.67% (common carp), while the, mean intensity was 7.56 (grass carp) and 4.56 (common carp). The prevalence with Trichodina sp. in common carp by season was as following: spring – 11.82%, summer – 3.44%, autumn – 7.85%, winter – 7.05%, while the mean intensity was: spring – 4.55; summer – 4.67; autumn – 4.40; winter – 4.72. Our findings of Trichodina sp. in grass carp in the present study is considered as the first record in Macedonia. Also, this fish species is regarded as new host for Trichodina sp. in Macedonian waters.","PeriodicalId":7009,"journal":{"name":"Acta Biologica Hungarica","volume":"4 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2020-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74619469","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Based on the analysis of the literature, we bring closer the mechanism of biofilm formation, including extracellular polymeric substances as well as cellular organelles, such as archaella, pili and ‘hami’. The method of forming a biofilm depends on the type of Archaea and the environment in which it naturally lives. We are also introducing the phenomenon of quorum-sensing, as a mechanism of communication of Archaea in the environment. This phenomenon corresponds to similar molecules as bacteria, namely acylated homoserines lactones, QS peptides, autoinducer-2 and -3 and others. In the case of biofilms and the occurrence of the phenomenon of quorum sensing, it can be concluded that these phenomena are very important for the life of Archaea. The phenomena described seem to be conservative, because both in Archaea and Bacteria are regulated by the same mechanisms.","PeriodicalId":7009,"journal":{"name":"Acta Biologica Hungarica","volume":"18 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2019-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"84996300","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
