Opis:
The gravid proglottids of Taenia saginata from human infection before and after treatment of patient with niclosamide (Yomesan) were used for studies on oncosphere envelope ultrastructure. The envelopes examined were intact after drug treatment. The samples from niclosamide-treated and untreated patients were similar with respect to number and kinds of the protective structures surrounding the oncospheres inside gravid proglottids. Their morphology was generally similar to this described earlier for other taeniid species. Details of the ultrastructure of oncospheral envelopes from niclosamide-treated patients are presented in the paper. Contamination of the environment with eggs from treated patients, particularly in poor sanitary conditions, is discussed.

Opis:
Introduction. Free-living amoebae, ubiquitous in outer environments, in predisposing circumstances may exist as parasites, infectious agents of Acanthamoeba keratitis. In recent decades, the vision-threatening corneal infection is a growing human health threat worldwide, including Poland. The applied therapy is often ineffective due to diagnostic mistakes, various pathogenicity of Acanthamoeba strains and high resistance of cysts to drugs; many agents with possible anti-amoebic activity are still being tested. In the presented study, selected chemicals are investigated in terms of their in vitro effect on corneal and environmental Acanthamoeba strains. Materials and method. Samples of a corneal isolate from a patient with severe Acanthamoeba keratitis,of assessed on the basis of genotype associations of 18S rRNA and the type strain, Acanthamoeba castellanii Neff cultivated in bacteria-free condition, were exposed to povidone iodine, chlorhexidine digluconate or toyocamycin. In vitro population dynamics of the strains were monitored and compared to those of control cultures. Results. All chemicals showed anti-amoebic effects with different degrees of effectiveness. Significant differences were observed in the in vitro population dynamics, and the morpho-physiological status of A. castellanii Neff T4 and corneal strains determined as A. polyphaga T4 genotype, exposed to povidone iodine or toyocamycin, in comparison with chlorhexidine taken as reference. Conclusions. Time-dependent amoebstatic in vitro effects were demonstrated for all agents, in particular, the results of assays with povidone iodine are promising. No significant stimulation of encystation appeared; however, as cysticidal efficacy of chemicals is expected, complementary research is needed on different Acanthamoeba strains with modified agent concentrations and method application.

Opis:
Recent epidemiological reports have shown an increasing risk of E. multilocularis infection among red foxes and humans in Poland. The aims of the study were: (1) to improve the early detection of alveolar echinococcosis (AE) in humans by implementation of clinical, imaging, immunodiagnostic, ultrastructural and molecular methods, (ii) to realize the parasitological verification of registered cases suspected of alveococcosis by the specialized, parasitological centres, and (iii) to standardize diagnostic and therapeutic procedures for this severe parasitic disease. Since 1993, eight cases of AE were registered in the Poznań centre. The final diagnosis was based on PAS-positive staining of lesions by histopathology or a detection of the parasite’s DNA in liver sections. Collaboration with physicians of various medical specialities is crucial for an early and more effective recognition of AE. Alveococcosis should always be considered in the differential diagnosis of space-occupying lesions in the liver suggesting slow-growing cancer.

Opis:
Introduction. The protozoan Trichomonas tenax is considered to be a human specific flagellate of the oral cavity, found in humans with poor oral hygiene and advanced periodontal disease. Morphological variability and great similarity between species occurring in humans and animals, complicate the specific identification of trichomonads, using microscopic examination and other standard parasitological techniques. Objective. The aim of the study was to search for and identify T. tenax in domesticated animals using molecular methods. The obtained data were assessed in terms of potential effects of a spread of the species deriving from the animals in the human environment. Materials and method. 301 animals: 142 dogs, 57 cats and 102 horses, were examined in terms of their mouth status and occurrence of trichomonads. ITS1–5.8S rRNA-ITS2 region was amplified and sequenced. Results. Finally, 7 dogs, 3 cats and 1 horse were diagnosed positive for T. tenax by PCR. In the oral cavity of 9 /11 animals, gingivitis and dental plaque accumulation were diagnosed. 9 /11 sequences of trichomonad isolates showed 100% identity with T. tenax sequence derived from the GenBank. The sequences of 2 isolates differed by substitutions. Conclusions. It was proved that T. tenax, considered so far as a human specific parasite, can also inhabit the oral cavity of dog, cat and horse. To summarize, T. tenax was detected in the mouths of different domesticated animals, indicating that in Poland it can colonize a wider range of hosts than previously known. The owners of 3 dogs showed oral tissue inflammation of different intensity and were also positive for T. tenax; therefore, oral trichomonosis spread from humans to domestic animals and conversely should be taken into consideration.

Introduction and objective. In recent decades the use of orthodontic appliances in Poland has increased; however, data on their influence on changes of components of the microbiome connected with oral biofilm are scarce. The objective of this study was to evaluate oral microbiota in terms of their role as risk factors for health complications. Materials and method. The study included 100 patients treated with removable or fixed appliances. Oral hygiene and gingival health were determined, and periodontal swabs taken from each patient for parasitological, bacteriological and mycological microscopic and in vitro examinations. Results. Oral protists and various pathogenic and opportunistic bacterial and fungal strains were identified in the superficial layer of biofilm. A higher prevalence of bacteria, Enterococcus faecalis, E. faecium, Staphylococcus aureus and Escherichia coli, and various strains of yeast-like fungi from the Candida albicans group, occurred in patients treated with the fixed appliance than in those using a removable appliance or not treated orthodontically. In some periodontal samples from patients treated with fixed appliances, cysts of the Acanthamoeba spp. were found. Conclusions. The use of orthodontic appliances alters the status of the oral cavity; it has impact on the colonization of oral biofilm by opportunistic/pathogenic strains, and increases the risk of their dissemination to various human tissues and organs. Pretreatment examination of oral microbiome, its monitoring particularly during treatment with fixed appliances, and preventive elimination of the potentially pathogenic strains to avoid health complications, are highly recommended, especially in patients with impaired immunity.

Opis:
Recently, incidents of Acanthamoeba keratitis, the vision-threatening eye disease, are reported with increasing frequency worldwide, particularly in contact lens wearers. In our study, the retrospective assessment of in vitro dynamics of subsequent pathogenic Acanthamoeba isolates cultured at 24°C, detected in Polish contact lens wearers with keratitis is presented and results compared with those of environmental A. castellanii Neff strain. There were delayed the proper diagnosis that influenced prolonged and severe course of this eye disease and treatment difficulties. The corneal material was examined directly to visualize developmental amoeba stages for diagnose verification, microbiologically tested for the specific identification of bacteriae and fungi, and in vitro grown in culture medium in temperature 24°C. Among twenty-six keratitis incidents analyzed, eleven were cases of Acanthamoeba keratitis; in the six of them, Acanthamoeba strains and concomitant bacterial and/or fungal infectious agents were detected. In vitro assays showed variability in population density of several clinical strains in the exponential growth phase expressed in various range of overall amoeba number and different proportion between trophozoites and cysts. The clear influence of temperature on the in vitro cultivation of the amoebae was observed: statistically significant lower population dynamics was revealed by most of pathogenic clinical isolates in comparison with those showed by environmental strain. The in vitro monitoring of dynamics of Acanthamoeba strains isolated from infected eyes may be helpful for diagnostics verification, especially in mixed infectious keratitis.
