Identification and characterization of coagulase-negative staphylococci isolated from intramammary infections (IMI) in cattle. Working team: Jarosław Król, Anna Wanecka
In many countries, coagulase-negative staphylococci (CNS) have been isolated more and more frequently from cases of IMI in cattle (Pyörälä i Taponen, 2009; Lange i wsp. 2015). There is an increasing evidence that these microorganisms represent a heterogeneous population that vary in pathogenicity, specific host-pathogen relationships and resistance to antimicrobials (Zadoks i Watts, 2009; Podkowik i wsp., 2012). Therefore, accurate species identification of CNS associated with mastitis in cows may be of practical importance for the determination of both epidemiologic (e.g. possible sources and modes of transmission of a microorganism), as well as clinical aspects of the infection. Our research is focused on elaboration of the most useful methods of the identification of CNS by various diagnostic methods (sequencing of the 16S rRNA and “housekeeping” genes, MALDI-TOF technique, determining of phenotypic properties) (an article and doctoral dissertation of Anna Wanecka are in preparation).
The knowledge on CNS isolated from intramammary infections in cattle, despite intensive research of many investigators, seems to be still insufficient. It turns out that IMIs may be, to a higher and higher degree, caused by atypical and rarely encountered CNS that are poorly characterized clinically and epidemiologically. An example of such microorganisms may be Staphylococcus microti, detected by us in a group of animals on a dairy farm (Król i wsp. 2016). We found out that all isolates of that species, recovered in the nearly 2-year-period, belonged to the same genotype, thus suggesting a contagious form of mastitis. This is a novel finding because CNS have been so far considered to be environmental pathogens, not spreading from cow to cow easily. A similar situation may apply to a closely related species, Staphylococcus rostri, isolated by us on another farm (an article under preparation).

Epidemiology of fungal infections of the C. neoformans/C. gattii. - Magdalena Florek
Cryptococcosis is an infectious disease of humans and animals occurring worldwide. It is assumed, about 1 mln of cases of human infections is noted annually, among them 62,5% eventually ends with death of a patient. Data concerning frequency of cryptococcosis in animals is lacking, though it was estimated that during the largest outbreak of Cryptococcus gattii infections that took place in Canada, number of animal cases observed was about 75% higher than those of human cases. Cryptococcosis, associated mainly with CNS and respiratory infections, is caused by a complex of fungi occurring in an environment and belonging to the genus Cryptococcus (C. neoformans/C. gattii complex). The main source of infectious propagules of the pathogen are tree and pigeon feces.
Using several genotyping methods, eight molecular types were distinguish among the complex, which differ in presence of virulence factors, course of infection they cause, epidemiology, geographic extent, ecological niche and mating type. There are reports showing that the most virulent molecular types display different resistance patterns against antimycotic drugs. The molecular types also correspond with the new classification of C. neoformans/C. gattii complex, which was introduced in 2015.
In Poland, cryptococcosis is not notifiable disease, neither animal nor humans cases, epidemiological investigation considering an environmental contamination with above mentioned fungi have never been carried on, moreover Cryptococcus strains occurring in the country are usually not identified to the species/molecular type level.
In order to evaluate the occurrence of fungi belonging to the C. neoformans/C. gattii complex, the isolation is carried out from environmental samples (tree swabs, samples of soil, pigeon feces). Obtained environmental isolates as well as clinical strains originating from animals and humans (cooperation with Wrocław Medical University) are analyzed using MLST method and their mating type is determined.
Research planned will allow to assess the occurrence of fungi of C. neoformans/C. gattii complex in the environment of Lower Silesia area as well as to compare frequency of occurrence of particular molecular types among clinical and environmental isolates.

Abortogenic viruses in horses - virological and epizootiological studies. Working team: Barbara Bażanów, Łukasz Gadzała
Abortogenic viruses are one of the main reason of abortion in horses. These includes equine arteritis virus (EAV), equine herpesvirus type 1(EHV-1) and sporadically equine herpesvirus type 4 (EHV-4). Infection of these pathogens causes huge economic losses and problems with international trade of horses. These infections are dangerous, because often there are not limited to individual animals, and often spread within the herd. Additionally, these viruses cause many respiratory symptoms such as dyspnea, serous, mucous or purulent disharge from the nose or coughing. Similar symptoms are observed during infection of other, widely widespread in Poland viruses of horses, which influence on a health status and productivity of these animals: equine influenza virus (Orthomyxoviridae) H7N7 and H3N8 and horses rhinoviruses ERhV type A, B1 and B2 (Picornaviridae). West Nile virus (WNV) and USUTU virus begin to appear in horses in the country, that in addition to the general symptoms cause inflammation of the brain and spinal cord. The purpose of the research carried out by the laboratory is monitoring of the epizootic situation of abortion and respiratory diseases in horses (EAV, EHV, ERhV and equine influenza virus), and determination of the WNV infection level by using: virus isolation method in cell cultures and hemagglutination and hemagglutination inhibition tests. Seroconversion of WNV is tested in cooperation with National Health Laboratory Service in Johannesburg (South Africa) using ELISA test. blood serum, semen, organs of aborted fetuses, nasal swabs and archival materials from horses are used in the investigation. In addition, genetic studies are carried out on isolated viruses. Other activities include work on newly synthesized chemicals as potential disinfectants. Experiments on the cytotoxicity and virucidal properties of these compounds are carried out in cooperation with the University of Wrocław, and substances meeting the criteria of disinfectants may be used to disinfection of stables or skin and mucous membranes in horse. In addition to the standard methods, techniques based on luminescence and fluorescence are used. A similar series of studies on the substances of plant origin is carried out in cooperation with the Department of Phytopathologyof UP in Wrocław.

Virological, serological and molecular diagnosis of selected viral infections in birds living in the wild. - Barbara Bażanów
Viruses affecting wild birds in Polish are poorly know yet. The overal goal of this study is isolation and identification of viruses from sick or dead birds naturally occurring in the wild. Research includes a wide range of tests: isolation of infectious agents in embryonated chicken eggs, continuous cell lines RK-13, BHK and Vero, and in the primary chicken embryo fibroblast cell culture. Further experiments are based on the TEM and molecular biology techniques ,in which isolated an cytophatogenic agent is checked for belonging to one of a few selected families of viruses, e.g. herpesviruses, paramyxoviruses, poxviruses and filoviruses.
