Total joint arthroplasty is a commonly used surgical procedure in orthopedics. Revision surgeries are required in >10% of patients mainly because of prosthetic joint infection caused by bacteria or aseptic implant loosening caused by chronic inflammation. Encephalitozoon cuniculi is a microsporidium, an obligate intracellular parasite, capable of exploiting migrating proinflammatory immune cells for dissemination within the host. We used molecular detection methods to evaluate the incidence of E. cuniculi among patients who had total hip or knee arthroplasty revision. Out of 49 patients, E. cuniculi genotypes I, II, or III were confirmed in joint samples from 3 men and 2 women who had implant loosening. Understanding the risks associated with the presence of microsporidia in periprosthetic joint infections is essential for proper management of arthroplasty. Furthermore, E. cuniculi should be considered a potential contributing cause of joint inflammation and arthrosis.

Problems with parasitic infections are common in zoological gardens and circuses. In some animals it can lead to several disorders such as systemic disease, reproductive disorders (abortions and neonatal mortality), and even to death if severe illness is untreated. Thus, the aim of this study was to evaluate the prevalence of three common parasites in 74 animals from three zoos, and four circuses in Southern Italy. Antibodies to Toxoplasma gondii, Neospora caninum, and Encephalitozoon cuniculi were detected in 51%, 12%, and 20% of animals, respectively. Co-infections of T. gondii and N. caninum were reported in seven animals (9%) and co-infection of T. gondii and E. cuniculi in one animal. T. gondii, N. caninum and E. cuniculi seroprevalence differed in type of diet (P ≤ 0.0001; P ≤ 0.037 and P ≤ 0.004, respectively). T. gondii and E. cuniculi seroprevalence also differed in animal families (P ≤ 0.0001) and according to type of housing (P ≤ 0.003), respectively. Statistical differences were not found in other characteristics (gender, age, country of birth, origin, and contact with cats or dogs). This is the first serological study focusing on protozoan and microsporidian parasites in zoo and circus animals from Southern Italy and the first detection of antibodies to E. cuniculi in camels in Europe.

Encephalitozoon spp. is an obligate intracellular microsporidian parasite that infects a wide range of mammalian hosts, including humans. This study was conducted to determine the prevalence of Encephalitozoon spp. in wild living rodents from Poland, the Czech Republic and Slovakia. Faecal and spleen samples were collected from individuals of Apodemus agrarius, Apodemus flavicollis, Apodemus sylvaticus, and Myodes glareolus (n = 465) and used for DNA extraction. PCR, targeting the ITS region of the rRNA gene was performed. The overall prevalence of microsporidia was 15.1%. The occurrence of Encephalitozoon cuniculi in the abovementioned host species of rodents has been presented for the first time, with the highest infection rate recorded for A. flavicollis. Sequence analysis showed that the most frequent species was E. cuniculi genotype II (92.5%). E. cuniculi genotypes I (1.5%) and III (6.0%) were also identified.

OBJECTIVE: In recent years new infectious diseases, i.e. emerging or re-emerging diseases, have been coming to the forefront. Currently, microsporidia, considered to be a major cause of emerging and opportunistic infections particularly in immunocompromised individuals, are also included in this group. Therefore, the aim of our study was to map the prevalence of Encephalitozoon intestinalis and Enterocytozoon bieneusi infection in a group of patients and to compare it with the occurrence of specific antigens in immunocompetent people. METHODS: Detection of spores of both pathogens in faecal samples was performed by an immunofluorescence test using species-specific monoclonal antibodies. RESULTS: Positivity to E. intestinalis in 91 examined immunosuppressed patients reached 33% (30/91), while only 4.3% (3/70) of the control group samples were found to be positive (relative risk 7.7, p < 0.001). In case of E. bieneusi 14.3% (13/91) of immunocompromised patients were positive, as were 5.7% (4/70) of people from the control group (relative risk 2.5, p = 0.095). CONCLUSION: In case of development of any opportunistic infection, the infection is detected and removed in most cases at an early stage. The incidence of clinically manifested microsporidiosis in patients with immunodeficiency is rare as they are under constant medical supervision. However, we must not forget about opportunistic infections, and in case of any non-specific symptoms it is necessary to exclude or confirm the diagnosis for immediate treatment.

Toxoplasma gondii, Neospora caninum, and Encephalitozoon cuniculi are important infectious agents, with T. gondii and E. cuniculi having zoonotic potential. There are two main clonal lineages (types I and II) of T. gondii in Europe, but little is known about genotypes of T. gondii in wild animals. The aim of our study was molecular detection of these three pathogens in tissues of wild red foxes ( Vulpes vulpes) from the Czech Republic. Using PCR (B1 gene), we detected T. gondii in 10% of the animals that we tested ( n=100); N. caninum and E. cuniculi were not detected. The T. gondii samples were genotyped by single multiplex PCR assay with 15 microsatellite markers. Five samples were successfully genotyped as genotype II, a unique finding for T. gondii isolated from red foxes from the Czech Republic.

INTRODUCTION AND OBJECTIVES: Encephalitozoon cuniculi is an obligate intracellular parasite infecting especially domestic rabbits; however, spontaneous infections have been documented in other mammalian species such as dogs, cats, rabbits, horses, cows and sheep all over the world. Encephalitozoonosis is a chronic and latent disease leading to renal failure, encephalitis, disorders of brain and urinary tract, and may lead to death. There are limited reports on encephalitozoonosis in wildlife, which is why the aim of this study was to detect the prevalence of antibodies to E. cuniculi in European hares. MATERIALS AND METHODS: Samples of blood sera from 701 wild hares from the Czech Republic (n = 245), the Slovak Republic (n = 211) and Austria (n = 245) were examined by indirect immunofluorescence antibody test (IFAT); samples with titer ≥ 40 were marked as positive. RESULTS: The total seroprevalence of E. cuniculi antibodies was 1.42% with titres in the range 40-640. Antibodies to E. cuniculi were detected in 2.9% (7/245), 0.8% (2/245) and 0.47% (1/211) hares from the Czech Republic, Austria and the Slovak Republic, respectively. CONCLUSIONS: This is the first detection of antibodies to E. cuniculi in hares from Europe showing that hares could be exposed to E. cuniculi infection, however with a low rate.

BACKGROUND: Infectious diseases represent the greatest threats to endangered species, and transmission from humans to wildlife under increased anthropogenic pressure has been always stated as a major risk of habituation. AIMS: To evaluate the impact of close contact with humans on the occurrence of potentially zoonotic protists in great apes, one hundred mountain gorillas (Gorilla beringei beringei) from seven groups habituated either for tourism or for research in Volcanoes National Park, Rwanda were screened for the presence of microsporidia, Cryptosporidium spp. and Giardia spp. using molecular diagnostics. RESULTS: The most frequently detected parasites were Enterocytozoon bieneusi found in 18 samples (including genotype EbpA, D, C, gorilla 2 and five novel genotypes gorilla 4-8) and Encephalitozoon cuniculi with genotype II being more prevalent (10 cases) compared to genotype I (1 case). Cryptosporidium muris (2 cases) and C. meleagridis (2 cases) were documented in great apes for the first time. Cryptosporidium sp. infections were identified only in research groups and occurrence of E. cuniculi in research groups was significantly higher in comparison to tourist groups. No difference in prevalence of E. bieneusi was observed between research and tourist groups. CONCLUSION: Although our data showed the presence and diversity of important opportunistic protists in Volcanoes gorillas, the source and the routes of the circulation remain unknown. Repeated individual sampling, broad sampling of other hosts sharing the habitat with gorillas and quantification of studied protists would be necessary to acquire more complex data.

From 2011 to 2012, the occurrence of Enterocytozoon bieneusi and Encephalitozoon spp. was surveyed at 29 randomly selected localities (both forest areas and enclosures) across four Central European countries: Austria, the Czech Republic, Poland, and the Slovak Republic. Isolates were genotyped by PCR amplification and characterization of the internal transcribed spacer (ITS) region using Enterocytozoon and Encephalitozoon-specific protocols. PCR revealed 16 mono-infections of Encephalitozoon cuniculi, 33 mono-infections of Enterocytozoon bieneusi and 5 concurrent infections of both Encephalitozoon cuniculi and Enterocytozoon bieneusi out of 460 faecal samples. Two genotypes (I and II) were revealed by sequence analysis of the ITS region of Encephalitozoon cuniculi. Eleven genotypes, five previously found in other hosts including domestic pigs (D, EbpA, EbpC, G and Henan-I) and six novel (WildBoar1-6), were identified in Enterocytozoon bieneusi. No other microsporidia infection was found in the examined faecal samples. Prevalence of microsporidia at the locality level ranged from 0 to 58.8 %; the prevalence was less than 25 % at more than 86 % of localities. Enterocytozoon bieneusi was detected as a predominant species infecting Eurasian wild boars (Sus scrofa). The present report is the most comprehensive survey of microsporidia infections in wild boars within the Czech Republic and selected Central European countries.

INTRODUCTION AND OBJECTIVE: Microsporidia are identified as ubiquitous organisms of almost every animal group and are now recognized as emerging opportunistic pathogens of human. The risk factors include immunodeficiency, lack of sanitation, and exposure to contaminated water and infected animals. In Slovakia, the places with an increased risk of infection due to the presence of risk factors and routes of transmission are represented by Roma settlements. Therefore, the aim of this work was to study the occurrence of Encephalitozoon spp. and E. bieneusi in children living in Roma settlements. MATERIALS AND METHODS: Stool samples were examined of 72 clinically healthy children coming from a group of the non-integrated Roma minority for the presence of microsporidia Encephalitozoon spp. and E. bieneusi. Microsporidian spores were detected by standard Rylux D, staining and by PCR and DNA sequencing. RESULTS: Of the total number of 72 stool smears examined, 22 were positive, which represented 30.6%. By the Real Time PCR, E. bieneusi was detected in 3 samples (4.2 %) and E. cuniculi in 19 samples (26.4 %). By comparing the sequences with sequences in the GenBank, E. cuniculi genotype I (Accession No. AJ005581.1) and E. bieneusi genotype A (Accession No. AF101197.1). CONCLUSIONS: Microsporidia, as newly emerging pathogens of humans and animals, are characterised by the production of spores which are environmentally resistant. Diseases caused by them have a cosmopolitan occurrence. Although E. bieneusi and E. cuniculi belong to the most frequently diagnosed species of microsporidia in humans, in Slovakia, this is the first confirmed evidence of E. bieneusi genotype A, as well as E. cuniculi genotype I in humans by the molecular method.

Faecal samples were collected from 377 horses on 23 farms with varying management systems in the Czech Republic. Microsporidia were found on 16 farms and the overall prevalence of Enterocytozoon bieneusi and Encephalitozoon cuniculi was 17.3% (66/377) and 6.9% (26/377), respectively. The prevalence of E. cuniculi in horses over 3 years of age was significantly higher (10.0%) compared to younger horses (4.0%). No significant differences in prevalence were observed among stallions, geldings, and mares for both microsporidia. Significantly higher infection rates of E. bieneusi and E. cuniculi were recorded in horses kept in stables than those on pasture. Two genotypes of E. cuniculi (I and II) and 15 genotypes of E. bieneusi including six previously described and nine novel genotypes were detected. The most common genotype detected was E. bieneusi genotype D identified in 51.5% (34/66) of positive horses. The identification of E. bieneusi genotypes D, EpbA, G and WL15, which were previously reported in pigs, humans, raccoons and horses, indicates that horses could be a potential source of zoonotic infection in humans.
