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.

Opis:
The purpose of this study was to examine oral cavity condition, identify microorganisms and evaluate interrelation between protozoans, bacteria and fungi occurring in mouths of insuline treated diabetics. 30 men and women, 25-60 years old, were clinically assessed for their oral cavity condition including pH range. Fifteen of them were the insuline treated diabetics. Swabs taken of different sites of periodontium, dental plaques and dental pockets collected from each patients were used for detection and identification of protozoans, bacteria and fungi. Mucosal inflammation, dental caries, loose teeth, periodontitis were observed in the diabetic patients, whereas the oral cavities were generally in better condition in the control patients. Prevalence of the protozoan parasites Entamoeba gingivalis and Trichomonas tenax was higher in the control patients than in the diabetics (26.6% and 13.3%, respectively). Fecal bacteria Enterococcus fecalis, E. faecium, Klebsiella pneumoniae occurred with significantly higher frequency in the insuline treated patients (60%) than in the control (6.6%). Various Candida albicans strains were more often found in the diabetic (53.2%) than in the control patients (13.3%). The results of our studies show a clear interrelation between alteration of oral health and the occurrence of microorganisms in the insuline treated diabetics. Metabolic disease that causes serious multi-organ disturbances as well as insulinotherapy are the very important factors changing oral cavity ecology of the persons with diabetes mellitus; decresed pH (the average 5.5) may inhibit development of infection with protozoans in the oral cavity of these patients and favour subclinical infections with other microorganisms. Thus, in the insuline treated diabetics, examination of mouths with regard to the occurrence of opportunistic fecal bacteria and fungi, particularly before a therapy with antibiotics is strongly recommended.

Opis:
The objective of the present study that has been carried out in the Institute of Chemistry, Warsaw University of Life Sciences, was to investigate antimicrobial activity of a number of sweet marjoram extracts. Raw (fresh or dried) plant material from culinary or medicinal herbs may contain varying amounts of bacteria or protozoa, including some known human pathogens. The isolates, which are prepared by procedures involving the use of elevated temperature and/or organic solvents or other chemicals are expected to have considerably less or no such potentially harmful burden. Four sweet marjoram (Origanum majorana L.) fractions obtained by steam distillation, Soxhlet n-hexane extraction, extraction with aqueous ethanol, and with ethanolic ammonia solution were evaluated in vitro for activity against twenty Gram-positive or Gram-negative bacterial strains, six Candida sp. yeast strains and a single protozoan species Pentatrichomonas hominis. The n-hexane extract showed the highest antibacterial activity and inhibited growth of eight out of nine Staphylococcus aureus strains used. The other bacteria showed no substantial susceptibility to the extracts, except that Acinetobacter baumannii showed some inhibition by the aqueous ethanol extract. The isolates were also active against three out of six Candida sp. strains used, and the ethanolic ammonia extract reduced the number of viable P. hominis trophozoites by 50% at 160 µg·ml-1 concentration in 24 h cultures; the remaining extracts were considerably less or but marginally effective. These data warrant further study on identifying the components of the extracts with the highest activities.
Celem badań prowadzonych w Katedrze Chemii Szkoły Głównej Gospodarstwa Wiejskiego w Warszawie było zbadanie aktywności przeciwdrobnoustrojowej otrzymanych wyciągów z majeranku. Materiał roślinny może być często zanieczyszczony różnymi bakteriami lub pierwotniakami, stanowiących zagrożenie dla zdrowia. Należy oczekiwać, że ekstrakty uzyskane w podwyższonej temperaturze i/lub z użyciem rozpuszczalników organicznych oraz innych substancji chemicznych będą istotnie mniej zanieczyszczone mikrobiologicznie. Zbadano aktywność przeciwdrobnoustrojową czterech izolatów z majeranku ogrodowego (Origanum majorana L.) otrzymanych poprzez destylację z parą wodną, ekstrakcję n-heksanem w aparacie Soxhleta, ekstrakcję suchego ziela majeranku wodno-etanolowym roztworem i wodno-etanolowym z dodatkiem amoniaku, wobec dwudziestu Gram-dodatnich szczepów bakterii, sześciu szczepów grzybów drożdżopodobnych z rodzaju Candida i pierwotniaka Pentatrichomonas hominis. Największą aktywność przeciwbakteryjną wykazał wyciąg n-heksanowy, który hamował wzrost ośmiu z dziewięciu badanych szczepów Staphylococcus aureus. Pozostałe szczepy bakterii nie były wrażliwe na ekstrakty stosowane w badaniu, z wyjątkiem szczepu Acinetobacter baumannii, którego wzrost hamował ekstrakt przygotowany z mieszaniny etanolu z wodą z dodatkiem amoniaku. Etanolowe wyciągi wykazały także aktywność wobec trzech z sześciu szczepów Candida, a wodno-etanolowy ekstrakt z dodatkiem amoniaku, redukował przy stężeniu 160 µg·ml-1 o 50% liczbę P. hominis; pozostałe wyciągi były znacznie mniej efektywne.

Opis:
In this research, a comparative analysis of results of investigations involving different human populations, in terms of a relation between the oral cavity health and the species composition of mouth microbiota is reported. The purpose of this analysis was to identify and assess microorganisms that could cause health complications in patients with neoplasm requiring dental problem-related surgical management. The patients with the oral cancer surgically treated and those without neoplasm were assessed for their oral health: status of teeth, gingiva, periodontium, and occurrence of inflammatory processes. From each patient, microorganisms isolated of periodontium, dental plaque, and dental pocket swabs were identified in wet and stained microscopic preparations; standard microbiology in vitro techniques were also applied to determine the fungal and bacterial strains. The comparative analysis of results of direct microscopic examinations and in vitro cultures assessment indicated significant differences in prevalences of fungi, parasitic oral protozoans and bacteriae in particular patient’s groups. Yeast-like fungi belonging to Candida genus, mostly of C. albicans group, were identified in 93.75% patients with the oral cancer, while in 25% of individuals assessed without neoplasm. E. gingivalis amoebae were only found in 12.5% patients with the serious disease; no trichomonads were detected in all patients analyzed. Among bacteria species, potentially pathogenic Enterobacteriaceae were found in the patients with oral cancer. The pronounced shift in the microbiota species composition in the patients who needed prolonged treatment due to oral cavity cancer, compared to other generally healthy persons has been showed in this analysis.

Opis:
The retrospective analysis of data on oral cavity clinical status in relation to microbiota species composition is presented. The research regards patients of different age, with and without congenital malformation, pretreatment assessed for occurrence of pathological changes in the masticatory system. Samples of the swabs collected from each patient (from dental plaque, periodontium and dental pockets) were used for identification of oral protozoans in wet slides and stained preparations; additionally, transmission electron microscope examination was performed. The material was used for in vitro cultures to identify bacteria strains. Clinically, intensity of tissue deteriorations was higher in patients with a congenital disease. Alive Trichomonas tenax and Entamoeba gingivalis, species with confirmed pathogenic impact on oral cavity and neighboring structures, were detected with higher prevalence in older patients. Enterococci, Staphylococcus aureus, various Enterobacteriaceae were more frequently detected in patients with somatic and mental retardations; in mouths of those patients, Klebsiella pneumonia and Pseudomonas aeruginosa opportunistic strains occurred. Masticatory system abnormalities favor colonization of oral cavity by exogenous species and dissemination of infections, especially dangerous for patients with congenital diseases. Oral microbiota assessment and preventive measures may be helpful to avoid subsequent peri-surgery complications.

The aim of this work was to study clinical changes and microorganisms in mouths of three patient groups: with congenital disorders (Cd), dialyzed (D) and control (C). Fifty five patients, 20 to 62 years old were assessed. Swabs and samples of periodontal tissue were used for microscopical study to detect of protozoans and for bacterial and fungal cultures. E. Gingivalis and T. tenax were found in all groups. Three out of Cd patients were infected with Acanthamoeba sp. Fecal bacteria were more often found in D than Cd. In all 30-40 years old D patients, fecal bacteria and various strains of C. albicans occurred. We found that systemie diseases favour instabilities in mouths changing interrelations between protozoa, bacteria and fungi. It may increase risk of clinical complications.
