Abstract
Blastocystis is one of the most frequently detected protozoa in the human large intestine. One of the most effective and cheap methods for detecting Blastocystis in faeces is culture on a special medium in anaerobic conditions. Sampling faeces using traditional containers and their transport to the laboratory has certain limitations: a sample taken in this way should reach the laboratory relatively quickly, moreover, some patients are uncomfortable during sampling and protection of material in this way. We propose utilizing a swab for sampling and transportation of the faeces samples to be examined for Blastocystis instead of using traditional containers. We believe this is an excellent method allowing the material to be transported over longer distances without additional, and sometimes expensive, safety measures, and at the same time permitting the possibility of obtaining living cells after a relatively long period of storage.

Abstract
Background The consumption of raw or undercooked meat, especially pork, and offal containing infective tissue cysts is suspected to be a significant route of infection with Toxoplasma gondii. Although the use of “animal-friendly pig production systems” ensuring direct contact with the natural environment offers ethical benefits, it limits the ability to ensure animal health; it may also increase the probability of infections by pathogens such as T. gondii, and thus their entry into the food chain. This study determines the seroprevalence of T. gondii in pigs from different housing systems and farms with different hygiene standards in Poland, as well as among pigs of different age groups from farms with high hygiene standards. In total 760 pig serum samples were examined for the presence of specific antibodies using the PrioCHECK® Toxoplasma Ab porcine commercial ELISA test (Prionics, Switzerland). Results Test results with PP ≥ 20% were regarded as positive, as indicated by the manufacturer. Antibodies to T. gondii were found in 193 of 760 (25.4%) tested sera. Regarding different housing systems, antibodies were found in 117 pigs: of these, 52.6% (61/116) were from organic farms, 40.9% (47/115) from farms with low hygiene standards, 5.4% (9/167) from farms with high hygiene standards and 0% (0/40) from a farm with a high level of biosecurity. Regarding age groups, antibodies were found in 76 animals on farms with high hygiene standards: 11.1% (7/63) were pigs younger than 3 months, 0% (0/60) aged 3–4 months, 12.3% (7/57) aged 5–6 months (final fattening stage) and 43.7% (62/142) were sows aged 9 months and older. Conclusions Antibodies to T. gondii were most often found in pigs from organic and low-hygiene farms, as well as in pigs aged 9 months and older. Meat derived from seropositive animals can pose a potential source of infection for humans. As maternal antibodies to T. gondii can be present in the blood of piglets aged up to 3–4 months, serological examination is unjustified in piglets up to this age.

Abstract
Blastocystis cf. Blastocystis hominis is the most common unicellular parasite found in human and animal intestines. Little is known about the life cycle, transmission and mechanisms of pathogenesis for this parasite. The aim of this study was to obtain new data on the genetic diversity of Blastocystis in selected species of mammals found in the Białowieża Primeval Forest (BPF), Poland, the best preserved lowland forest in temperate Europe. 113 faecal samples were collected in the period 2018–2020 from seven species of wild mammals occurring within the Polish part of BPF and its surroundings. Blastocystis was detected by molecular amplification and sequencing the small subunit rRNA gene. The overall prevalence of Blastocystis in animals was 8.9%. A larger number of stool samples (90) were collected from European bison and only for this species was it possible to calculate the prevalence of infection (5.6%). The isolates obtained from European bison were classified as ST1, ST3, ST5, ST7. Blastocystis was also detected in the grey wolf (Canis lupus) (ST5), wild boar (Sus scrofa) (ST5) and red deer (Cervus elaphus) (ST1). In conclusion, for the first time we have demonstrated the presence of Blastocystis in wild European bison. Preliminary studies have shown that Blastocystis is present in at least 4 species of wild mammals in the BPF area and that it exhibits great genetic diversity. Blastocystis is present in wild mammals in the Białowieża Primeval Forest Blastocystis in the Białowieża Primeval Forest exhibits great genetic diversity Intra-species and interspecific transmission of Blastocystis in Białowieża Primeval Forest is highly probable.

Abstract
Blastocystis cf. hominis is an unicellular protozoan parasite commonly found in the gastrointestinal tract of humans and animals. Blastocystis is characterized by high morphological and genetic diversity. Studies based on the analysis of Blastocystis spp. small subunit ribosomal RNA genes (SSU rDNA) have identified 26 subtypes (ST) so far, including at least 10 isolated from humans (STs 1-9 and ST12). In 2017, stool samples from a dog and its two owners living in Gdynia, Poland were examined; all three were suffering from chronic diarrhoea. In addition, 30 faecal samples were also examined from 30 dogs kept in one of Warsaw's hotels for animals. Stool specimens were analyzed using anaerobic cultivation at 37°C with a modified Jones' medium and molecular methods (PCR). Phylogenetic analysis using Bayesian inference was performed. Vacuolar forms of Blastocystis were identified in the stool samples of the dog and its owners; Blastocystis were not detected in any sample from the dogs living in the animal hotel. Based on the phylogenetic analysis, the obtained isolates were classified as subtype ST3 (for Owner 1) and subtype ST7 (for Owner 2 and the dog). To the best of our knowledge, the present study is the first to evaluate the presence of Blastocystis in canines in Poland, including domestic dogs.

Abstract
Herein we describe the origin of the International Commission on Trichinellosis more than 60 years after its foundation. We attempt to clarify previous debate over the founding presidents and particularly the role of Polish parasitologist, Zbigniew Kozar. Seminal and core proceedings of the Commission published in Wiadomości Parazytologiczne and other records were used to advance this goal. An early regional commission initially held in Budapest, Hungary at the Hungarian Meeting of Parasitologists was devoted to trichinellosis and was presided over by Kozar from 1958 to 1960. However, the official formation of the Commission did not occur until 1960 during the 1st International Conference on Trichinellosis held in Warsaw, Poland, where Witold Stefanski was elected president. During the 2nd International Conference on Trichinellosis, which was held in 1969 in Wroclaw, Poland, Samuel E. Gould was elected president until his untimely death in 1970. Zbigniew Kozar was secretary general from 1960 to 1972. Beginning with the 3rd International Conference held in Miami, Florida, USA in 1972, the activities of the Commission and the Conference became better documented.

Abstract
We investigated the genotypes of Francisella tularensis (F. tularensis) strains isolated in Poland during the period 1953-2013 and studied their genetic relationship to F. tularensis strains isolated in other countries using MLVA. We examined the mosquito and tick samples collected in Poland for the presence of F. tularensis DNA using PCR. Our results revealed a high genetic diversity among the strains of F. tularensis collected from Poland, suggesting that the bacterium is commonly found in the environment. However, we did not detect F. tularensis DNA in ticks and mosquitoes, showing that the arthropod bites might not be the main source of infection. We also propose the application of a practical assay called v4-genotyping that can be directly performed on the clinical and environmental samples. In addition, we discovered genetic variations among Schu S4 reference strains used in various laboratories and showed that MLVA analysis should not be based on amplicon sizes only because point mutations occurring within the MLVA loci might not always be manifested by a change in the amplicon size.

Abstract
Dirofilariasis is a parasitic disease of dogs and other carnivores transmitted mainly by the mosquitoes of the genera Culex, Aedes, Anopheles. Full life cycle of the Dirofilaria nematodes in humans is extremely rarely observed, usually lacking species determination at the molecular level. We report fully documented unusual clinical manifestation of subcutaneous dirofilariasis with intensive microfilariemia in peripheral blood revealed by the Knott's concentration technique. The identification of the Dirofilaria repens nematode was based on typical morphological findings for adult gravid female nematode found in the histopathological preparations. The morphology of microfilariae obtained from patient's peripheral blood was also typical for D. repens. The final identification was confirmed by the molecular analysis of microfilariae collected from the blood.

Abstract
INTRODUCTION AND OBJECTIVES Blastocystis hominis s. l. is one of the most commonly detected protozoa in the human large intestine. The aim of the study was to determine the genetic subtypes of Blastocystis hominis s. l. occurring in humans in Poland. MATERIALS AND METHODS Stool samples from patients diagnosed in the Laboratory of the Department of Parasitology, National Institute of Public Health – National Institute of Hygiene (NIZP-PZH) and in the Parasitology Laboratory of the Hospital for Infectious Diseases in Warsaw were examined. Blastocystis subtypes were assayed based on the fragment of small-subunit ribosomal RNA gene sequences (SSU rDNA). RESULTS The examined isolates were classified into five Blastocystis subtypes (STs), fifteen of which belonged to ST3, three to ST1, two to ST2, two to ST6, and one isolate belonged to ST7. In three cases the subtype of isolate was not identified. DISCUSSION AND CONCLUSIONS In Poland, the subtypes ST1, ST2, ST3, ST4, ST6 and ST7 have been reported in humans so far. The ST6 and ST7 subtypes are rarely detected in humans in Europe. In Poland, the ST6 subtype was previously described in chickens. On the basis of the studies, it was found that Blastocystis isolated from humans in Warsaw show high genetic diversity. In order to determine the possible pathogenic potential of individual Blastocystis subtypes, special epidemiological studies are required.

Abstract
Hepatitis E virus (HEV) is known as zoonotic agent. The main reservoirs of HEV in Europe are pigs, wild boars, and deer. Hunting activity is considered to be a risk factor for HEV infection. We conducted a cross-sectional study among 1021 Polish hunters. To understand socio-demographic characteristics of this population and to gather information on potential exposures, all participants completed a questionnaire. Commercial immunoassays were employed to estimate seroprevalence anti-HEV. Samples with confirmed positive result of anti-HEV IgM were examined for HEV RNA. Anti-HEV IgG were identified in 227 people, 22.2% of the studied group. Seroprevalence among the studied hunters was associated with age ≥65 [adjusted prevalence ratio (aPR) 1.6, p = 0.037), living in a house (aPR 1.54, p = 0.013), professional contact with farm animals (aPR 1.09, p = 0.01), and consumption of stewed offal (aPR 1.61, p = 0.00). Washing hands after disembowelment was linked to lower seroprevalence (aPR 0.53; p = 0.00). Lower prevalence of anti-HEV IgG among hunters living in cities was associated with age: 35–49 (aPR 0.52, p = 0.011) and 50–64 (aPR 0.93, p = 0.58), living in a house (aPR 1.58, p = 0.002) and owning a cat (aPR 0.58, p = 0.042). Among hunters living in rural areas, seropositivity was associated with contact with farm animals (aPR 1.66, p = 0.013) and consumption of stewed offal (aPR 1.81; p = 0.001). Contrary to initial assumptions, it was concluded that hunting was of significantly lesser importance than other factors. Due to the high level of HEV seroprevalence identified, we recommend conducting a large-scale study in the general population of Poland.

Abstract
Mites from the genus Demodex are ectoparasites of many mammals, including humans. There are over 100 Demodex species, which demonstrate strong specificity in host selection [Table 1]. The mites are common in humans. It has been estimated that up to 60% of adults may be infected, but in most cases no symptoms of the disease are present. Demodex multiplication inside sebaceous glands and hair follicles can lead to skin disease in both humans and animals. In humans, the main problem is ocular demodecosis, which can cause chronic conjunctivitis and blepharitis. In this paper, we present the biology and epidemiology of Demodex species in humans as well as in domestic and farm animals. Characteristic lesions, diagnostics and treatment of demodecosis are also described

Abstract
Aforesaid recommendations for the management of T.gondii infection, elaborated by the group of experts, are intended for physicians of various specialties in order to standardize and facilitate diagnostic and therapeutic management. Early diagnosis of congenital toxoplasmosis, both symptomatic and asymptomatic, in neonatal period, initiation of adequate treatment and long-term, multispecialist monitoring, including multi-organ rehabilitation of children may prevent or reduce the complications of congenital toxoplasmosis. Health education, whose role is often underestimated, should be targeted mainly on girls and women at reproductive age as to prevent from infection during pregnancy.

Abstract
UNLABELLED In Poland the development of the knowledge concerning zoonotic pathogens, of which free-living animals are the reservoir of is gaining in importance both in epidemiological aspect as well as in the context of prevention for improving public health. Dietary habits such as the consumption of forest undergrowth products and wild game meat, and the way of those products being prepared (in the process of barbequing) pose a risk factors of infection with the foodborne pathogens such as Echinococcus multilocularis, Trichinella spp., and HEV. AIM The aim of this study is to estimate the prevalence of infections caused by Trichinella spp., Echinococcus multilocularis, and HEV in the population of Polish hunters, describing their geographical distribution in Poland, and to try to define basic factors, which may contribute to their occurrence. MATERIAL AND METHODS In 2010-2012 a cross-sectional study was carried out among Polish hunters. A blood samples were collected as well as a survey of 1027 participants recruited in the 16 provinces was also carried out. Serological tests were performed for the presence of specific antibodies against Echinococcus multilocularis, Trichinella spp. and HEV using commercial or "in home" ELISA tests. In case of positive result for Echinococcus, an Em2plus ELISA or/and western blot test were carried out, and for positive results for IgM for HEV a recomLine HEV IgM test was carried out. RESULTS In the studied population a total number of 2 cases of Echinococcus multilocularis infection were found. Moreover in 47 (4,6%) participants presence of antibodies against Trichinella spp. were found, including 17 positive and 30 borderline results. In 206 persons (25%) IgG anti-HEV antibodies were found (by ELISA test). Geographical diversity in prevalence of both, the Trichinella spp. and HEV cases was observed. SUMMARY AND CONCLUSIONS The study confirmed presence of zoonotic infections such as Echinococcus multilocularis, Trichinella spp., and hepatitis E (HEV) among Polish hunters. In the case of Echinococcus multilocularis, and Trichinella spp., it appears that these infections are more common in the studied sample than in the general population. Additionally results on the prevalence of HEV infections indicate a need for further research on the occurrence of the virus in the country.

Abstract
Babesiosis is an emerging parasitic, anthropo-zoonotic tick-borne disease, seldom diagnosed in humans. Caused by Protozoa, Babesia (also called Piroplasma) intraerytrocytic piriform microorganism. Infection of vertebrates is transmitted by ticks. Out of more than 100 Babesia species/genotypes described so far, only some were diagnosed in infected humans, mostly B. microti, B. divergens and B. venatorum (Babesia sp. EU1). Infection in humans is often asymptomatic or mild but is of a particular risk for asplenic individuals, those with congenital or acquired immunodeficiencies, and elderly. Infections transmitted with blood and blood products raise concerns in hemotherapy. Epidemiological situation of babesiosis varies around the world. In Europe, no increase in the number of cases was reported, but in the USA its prevalence is increasing and extension of endemic areas is observed. The aim of this publication is to describe the problems connected with the current epidemiological situation, diagnosis and treatment of human babesiosis with regard to clinical status of patients.

Abstract
AIM The aim of the study was to assess the epidemiological situation of echinococcosis and cysticercosis in 2012 as compared to previous years. MATERIALS AND METHODS The assessment of the epidemiological situation was based on data contained in the individual reports on cases sent to the Department of Epidemiology NIPH-NIH by the Regional Sanitary- Epidemiological Stations and on the pooled data published in the annual bulletin "Infectious diseases and poisonings in Poland". RESULTS In 2012, the total number of reported cases of echinococcosis in Poland was 28. This included: 11 undefined cases (39% of all cases), 7 alveolar echinococcosis cases (41% out of l7 cases in which the species of Echinococcus was recognized) and 10 cystic echinococcosis (59% of all defined cases). The total incidence of echinococcosis was 0.073/100 000. Cases were registered in 8 provinces. Most cases (9) and the highest incidence (0.620) was recorded in Warmińsko-Mazurskie. Echinococcus infections were reported in people aged 15 to 82 years, mostly adults (mean age 49.2 years, median 54.0). Echinococcosis was more frequent among women (incidence 0.096) than among men (incidence 0.048). The incidence of echinococcosis in rural areas was higher than in the city (0.125 vs. 0.039). Cysticercosis, which occurs sporadically in Poland, was not reported in 2012. CONCLUSIONS For the purposes of epidemiological surveillance it would be advisable to introduce the obligatory differentiation of alveococcosis and hydatidosis, as well as a case definition for cysticercosis. In order to reduce the risk of contracting tapeworm infections, it is advisable to intensify educational efforts.

Abstract
Background Alveolar echinococcosis (AE) caused by Echinococcus multilocularis infections is a dangerous old disease in the Northern Hemisphere. The aim of the paper was to collect and analyze data on human AE in Poland in the last two decades. Methodology/Principal Findings The sources of data were both the cases officially registered and detected by an active field and laboratory surveillance. The cases were verified by clinical, epidemiological, and laboratory criteria. Altogether 121 human cases of AE were detected. Among these 83 (68,6%) cases were classified as confirmed, 16 as probable and 22 as possible. During the two decades a continuous increase in detection rate was noticed. The cases were 6–82 years old at the time of diagnosis (mean - 47.7 years). Sex ratio M/F was 0.86/1.0. The AE was fatal in 23 (19%) patients (mean age at death - 54.1 years). Family agglomeration of AE was found in 4 foci, involving 9 patients. Seventy six of the cases were diagnosed in an advanced stage of disease. In all cases the liver was the primary location of AE. In 30 (24.8%) patients a spread to other organs was observed. Ninety four of the patients were treated with albendazole. In 73 (60%) patients a surgical operation was performed, including 15 liver transplantations. Conclusions/Significance The studies confirmed that AE is an emerging disease in Poland, which is the fourth country in Europe with over 120 cases detected. The results also indicate the need of a wider national programme for implementation of screening in the highest AE risk areas (north-eastern Poland) with an effort to increase the public awareness of the possibility of contracting E. multilocularis, and above all, training of the primary care physicians in the recognition of the risk of AE to allow for an early detection of this dangerous disease. Human alveolar echinococcosis (AE) is a consequence of accidental ingestion of the eggs of the tapeworm Echinococcus multilocularis. AE constitutes a serious and increasing medical and epidemiological problem in many countries including Poland. The natural environments with a high AE prevalence are the areas where the definitive hosts (foxes, raccoons) and the intermediate hosts (rodents) live. The increasing population of infected foxes that penetrate nearby the village and urban buildings and infected dogs poses a certain risk to human health. This report is a joint clinical and epidemiological analysis of 121 AE cases recorded in the years 1990–2011 in Poland. The highest percentage of E. multilocularis infected foxes in the north-eastern regions of Poland (about 40% of the examined population infected) bears a clear-cut relation to the highest incidence of detected AE human cases in those areas. An epidemiological and clinical survey of the local population conducted for over a dozen years has contributed to the discovery of several new AE cases. Alveolar echinococcosis in humans caused by Echinococcus multilocularis infection belongs to the emerging diseases in Poland where a continuous increase in the detection rate was noticed during the last two decades.

Abstract
Dirofilaria (Nochtiella) repens Railliet et Henry, 1911 (Nematoda: Onchocercidae) is a subcutaneous parasite of dogs and other carnivorous animals, with human acting as incidental hosts. D. repens occurs endemically in warm climates on various continents, in Europe mainly in Mediterranean countries. The aim of this study was to summarize information on human dirofilariosis in Poland, taking into consideration parasitological and epidemiological data. Between April 2009-December 2011, in the parasitological laboratories of Medical University in Warsaw and the National Institute of Public Health/National Institute of Hygiene, fragments of affected human tissues and parasite specimens were examined microscopically. Molecular methods were used to confirm the results from eight microscopic investigations. A literature review to summarize all data on dirofilarial infections in humans in Poland was conducted. In these investigations, autochthonous dirofilariosis was found in humans for the first time in Poland. During the last 3 years, 12 new cases of human D. repens dirofilariosis were recognized. Since 2007, a total of 18 D. repens infection have been found in humans in Poland. Parasitic changes were located in various parts of the body, in the form of subcutaneous nodules containing single nematodes surrounded by granulation tissue (15 cases). In 3 cases, a subconjuctival localization was found. Seventeen of the 18 described cases were noted in central Poland where dirofilariosis occured in dogs. In this area, autochtonous infection was identified in 3 women who had never left Poland in their lives; the others were probably infected outside the country while staying in endemic regions. Data on human and canine infection collected from central Poland during the last 5 years indicates that Dirofilaria repens has been introduced into our country, and that the infection is successfully spreading, with the border of the endemic area currently on 52°N, 21°E. To control the epidemiological situation it is necessary to identify D. repens hosts within local mosquito populations, and to monitor dogs. Because of the increasing number of cases of human infections, whether introduced or local, physicians should take dirofilariosis into consideration in differential diagnosis of skin and eye diseases.
