The eye nematode Thelazia callipaeda Railliet et Henry, 1910 (Spirurida: Thelaziidae) is a vector-borne zoonotic nematode infecting a range of wild and domestic carnivores as well as humans. It is considered to be a causative agent of emerging and neglected disease and currently invades central part of Europe. Nematodes were collected from the eye of a dog living in Prague, which never travelled outside the Czech Republic. The nematodes were identified based on their morphology and partial sequence of the cox1 gene as T. callipaeda haplotype 1. This finding represents the northernmost record of autochthonous canine thelaziosis in Europe. The insufficient control of imported animals as well as free movement of dogs and wild carnivores within Europe probably facilitates spreading of T. callipaeda throughout the continent. To better understand the spreading of T. callipaeda and to prevent its zoonotic transmissions, information about the risk of this infection in newly invaded countries should be disseminated not only among veterinarians and physicians, but also within the community of pet owners and hunters., Milan Jirků, Roman Kuchta, Elena Gricaj, David Modrý and Kateřina Jirků Pomajbíková., and Obsahuje bibliografii
We observed instances of cannibalism (intraspecific predation) among intra-instar larvae of Culex pipiens Linnaeus, 1758 while performing a bioassay of Lysinibacillus sphaericus (formerly named Bacillus sphaericus) larvicide, when the larvae were exposed to the larvicide for 48 h in the absence of food. Larvae without symptoms of poisoning attacked and devoured those visibly affected. Cannibalism was more prevalent in 1st-2nd instar larvae than in 3rd-4th instar. This phenomenon should be taken into account when interpreting the results of larvicide bioassays, especially when the exposure lasts over 24 h. The necessity of creating optimal conditions for organisms tested is emphasised., Igor Uspensky and Sergei Braun., and Obsahuje bibliografii
A new species, Castosyringophilus meropis sp. n., found in quills of feathers of the European bee-eater Merops apiaster Linnaeus (Coraciiformes: Meropidae) is described. This new species is close to C. claravis Skoracki et Glowska, 2008 and differs, in females, by the presence apunctate coxal fields (vs sparsely punctate in C. claravis) and by the lengths of setae d1 145-180 µm, f2 170-185 µm and ag3 190-215 µm (vs d1 200-220 µm, f2 230-250 µm and ag3 150-170 µm). We present a vast mite material collected from bee-eaters originated from different localities in Europe, Asia and Africa, both breeding and wintering grounds of this bird. It indicates that the whole world population of the European bee-eater is parasitised by this quill mite species., Maciej Skoracki, Martin Hromada, Bozena Sikora., and Obsahuje bibliografii
The research activities of this Centre are focused on the study of cyanobacteria, algae and symbiotic soil microorganisms (bacteria and algae), which are used for bioindicatoin and revitalization of toxic anthropogenic substrates and water resources. The targeted outcomes are methods for predicting cyanobacteria in drinking wter and water resources, technology of biogas production from algal biomass and the use of algal biomass for the pharmaceutical industry and biotechnology of microbial inoculations for more effective recultivation of brown-coal spoil banks. The research Centre is divided into three research groups each dealing with a portion of the research task: Group 1 - Cyanobacteria and their toxins in the waterworks industry; Group 2 - Use of algae for bioindication and revitalization of polluted water and biomass use; Group 3 - Use of microbial inoculations for soil revitalization. and Miroslav Vosátka, Jana Albrechtová.
