Biology Centre Collection of Organisms (BCCO) is a structure of the Biology Centre CAS that associates some of its collections of
organisms. Detail information about the isolates and specimens can be found on the webpages of the collections bellow. For
more information or terms of use of the listed material, please, contact the collection curators.

The Collection of Spirochaetes was founded with the support of the Ministry of Agriculture of the Czech Republic during the project QK1920258 “Changes in distribution of ticks and tick transmitted diseases: new and neglected risks for domestic animals, livestock and humans.”. The Collection is in the Laboratory of molecular ecology of vectors and pathogens of the Institute of parasitology BC CAS and it includes various living spirochaetes originating from ticks, livestock, domestic, as well as from wild animals from the Czech Republic. The isolates can be provided for further research or applications.
The genotypic variability of Borrelia from ticks is larger than originally expected. Borrelia representatives differ by their preference of tick vectors in the given geographic area of the Czech Republic, by their preference of hosts, as well as by their ability to infect humans. To better understand the ecology and epidemiology of spirochaetes, it is important to understand their genetic diversity in nature, especially in the highly endemic region represented by the Czech Republic. The first extensive genetic analysis comparing European populations of spirochetes B. burgdorferi is being performed with the use of DNA sequencing and multilocus analyses of the pathogen’s genomes. This analysis is focused especially on their diversity, pathogenic potential, distribution, and rise of recombinant genotypes increasing the danger of infecting humans. The analyses of genomes originating of the Czech strains will lead to successful identification of potential candidates for anti-spirochaete vaccines. The still growing collection of the Czech Borrelia strains is, among other reasons, critically important for the development of molecular detection and characterization laboratory techniques of wide spectrum of Borrelia species from nature as well as from clinical samples.


This collection serves as a depository of cultures of soil actinomycetes, used mainly for screening of strains producing important secondary metabolites. Most of the deposited cultures belong to the family Streptomycetaceae (genera Streptomyces, Streptacidiphilus, Kitasatospora), however members of other families such as Pseudonocardiaceae (genera Letznea, Amycolatopsis, Saccharothrix) and Nocardiaceae (Nocardia) are also present. We are opened to cooperate with research institutions, universities, as well as pharmaceutical companies on the research of substances with antibiotic or anti-inflammatory effect.

The collection holds more than 2000 strains of filamentous fungi (Ascomycota, Zygomycota, and their related anamorphic stages) isolated mainly from soil and sediments from the Czech Republic, Germany, Russia, USA, and Macedonia, and also from air, litter, caves, intestines and fecal pellets of soil invertebrates, and vermicomposts. The main function of this collection is to collect, maintain, and supply cultures of microscopic fungi and to provide information on microscopic fungi by publishing a catalogue of strains. The cultures are used for basic and applied research, pharmaceutical and food industry, agriculture, medicine, education and general scientific interest.


The collection includes mainly isolates from soils, caves, deep substrates, soil-forming sediments both mineral and organic origin, digestive tracts and excrements of soil invertebrates, but also from manure and intestine of livestock. Cultures are used mainly for scientific and teaching purposes. Currently, one of our priority topics is an occurrence and spread of bacterial resistance to antimicrobials in the environment. The tetracycline resistome of some of our cultures is characterized in particular.

The collection includes about 2000 strains of microscopic algae and cyanobacteria isolated from soils and aerophytic habitats of various biotopes and climatic zones. Cyanobacteria cover about 20% of the total spectrum of maintained strains, filamentous morphotypes (from the orders Nostocales, and Synechococcales) prevail. Eukaryotes are mainly represented by strains of green algae (Chlorophyceae, Trebouxiophyceae, less Ulvophyceae, Streptophyta) together with stramenopiles (Xanthophyceae, Eustigmatophyceae). Maintained algal isolates represent an important resource of biologically active compounds with biotechnological potential (e.g. polyunsaturated fatty acids, carotenoids), representatives of heterocytous cyanobacteria are known to produce many bioactive metabolites (e.g. toxins, enzyme inhibitors, antifungal and antitumor substances), some isolates indicate potential use as soil bioconditioners.

The collection consists of 37 species and 429 individual isolates of clinically more or less important viruses belonging to six viral families. Among others the collection contains a unique time series of tick-borne encephalitis virus isolates since the first occurrence of the virus in Central Europe. The isolates of virus strains are an important source of biological material serving for basic research (studying host-pathogen interactions, evolutionary etc.), but also have practical applications in epidemiological studies or serve as a source of biological material for diagnostics development or biotechnology.

A large collection of helminths comprising about 3000 species (partly not yet registered) from around the world, including numerous type specimens, is available for comparative studies to helminthologists from various countries. Exceptionally, some parasitic crustaceans and pentastomids are included in the collection.


A collection of holotypes and paratypes of about 300 species of parasitic arthropods on 430 microscopic slides is deposited at the Laboratory of Parasitic Arthropods. A large collection of several thousand specimens of parasitic mites and fleas from mammals, birds and reptiles, and a small collection of ticks in alcohol, are deposited in the same laboratory. The Institute maintains laboratory colonies of ticks (8 species), mosquitoes (4 species, 5 lines) and arboviruses (33 species and strains).

The collection includes predominantly isolates of phytopathogenic fungi. In some fungi that damage plants, viruses are found to reduce the ability of the fungus to act as a pathogen: they limit fungal growth rate, reduce sporulation and/or its ability to infect a particular host. Thus, these viruses can be potentially used as the biological control of the phytopathogenic fungi.

At the Institute of Entomology, a valuable material from several groups of (not only) insects have been assembled in the past. Particular collections were built by the Institute employees from the very beginning of the Institute’s existence. The collections are not useful to the taxonomists only, they are also being used by the scientists of other specializations, for instance for the purpose of the comparison of species, that are identifiable with difficulty. Some of our most valuable collections are represented by the collection of aphids and mayflies. The aphid collection is the only reference aphid collection in the Czech republic and its volume places it within important collections also on the European scale (approximately 130 000 microscopic slides, type material for more than 200 species). Our mayflies collection represents the largest one of this insect order within the Czech republic and one of the largest ones on the European scale, containing approximately 1 000 000 specimens with type material from more than 100 species.
