Opis:
Amphizoic amoebae belonging to the genus Acanthamoeba are known as etiological agents of sightthreatening Acanthamoeba keratitis. The leading risk factor for the development of this serious human disease is contact lens wearing which popularity increases worldwide, also in Poland. The disease with active epithelial inflammations, corneal ulcers, including loss of the visual acuity is a serious medical problem as an emerging threat for the public health related to improper contact lens hygiene. The treatment of the amoebic keratitis is difficult, often unsuccessful due to delayed proper diagnosis. The clinical picture of the disease, often with severe course is nonspecific, similar to that occurring in viral, fungal or bacterial keratitis, thus clinical symptoms alone are not sufficient to identify the causative agent of the amoebic infection. Early diagnosis is decisive for the suitable therapeutic management and the treatment efficacy. In our studies, several complicated, difficult to treat Acanthamoeba keratitis incidences pertaining Polish patients using contact lenses have been retrospectively analyzed in terms of the usefulness of non-invasive methods of in vivo confocal microscopy and in vitro culture techniques applied for diagnosis. Hyper-reflective double-walled spherical Acanthamoeba cysts, with a more reflective outer wall were detected in the epithelium and anterior layers of the corneal stroma. In vivo confocal microscopy, if available, may be a valuable, sensitive tool for diagnosis in late identified severe infections mainly with strong viability strains, however confoscan may offer limited value at lowintensity amoebic infections. The microscopic visualization of amoebae in slides prepared directly from corneal scraping and laboratory examinations of specimens from in vitro cultivated corneal isolates allow to confirm or verify results of in vivo examinations, furthermore to identify directly the pathogens and to clarify previous misdiagnoses.

Opis:
Different Acanthamoeba species are amphizoic organisms distributed in wide range of habitats in natural and man-made environments; they are also detected on surfaces of equipment and accessories in health facilities. Some strains of the amoebae are causative agents of the vision-threatening human disease Acanthamoeba keratitis, mainly reported in contact lens wearers. An exceptional high resistance of Acanthamoeba trophozoites and particularly cysts to chemicals, disinfectants and drugs is believed as influencing difficulty resulting in unsuccessful therapeutic management. As Acanthamoeba keratitis is the serious medical problem worldwide, different chemicals with possible activity against environmental and clinical Acanthamoeba strains are tested. In our study, selected disinfectants used in health care settings and laboratories were tested and their efficacy against the corneal strains Acanthamoeba castellanii and A. polyphaga , and environmental A. castellanii Neff strain was assessed. Comparative assessment of results of the assays show that, apart from amoebistatic effects, the disinfectants indicated expected cysticidal efficacy.

Opis:
The purpose of this study was to determine the in vitro susceptibility to 6 antifungal agents of 143 strains of Candida species isolated from 545 patients with suspicion of fungal infection. Test ATB Fungus (bioMerieux) was used. Among all Candida isolates 91.6% were susceptible to tested polyenes and 32.9% to all azoles. Less susceptible to polyenes isolates were noted in low percentage (0.7 to 4.2%) and to azoles more frequcntly (32.9 to 41.2%). Candida isolates resistant to antifungal agents tested were dependent from the kind of clinical samples and species of fungi. Monitoring of the susceptibility to antifungal agents by ATB commercial test seems to be uscful tool for therapeutic purposes.

Opis:
The larvae of Anisakis simplex had the largest influence upon decreasing the activity of porcine pepsin. The activity of that enzyme in tests, where the larvae were present during the entire period of incubation, was lower than in the controls. No similar trends were observed in case of the solutions with bovine and porcine trypsin. The activity of those enzymes in the solutions containing the larvae was higher than in the controls. Only the activity of porcine trypsin after 10 h of incubation was slightly lower in the experimental sample than in the control, however, during the later hours the dynamics of the activity decrease of that enzyme in the controls was higher than in the experimental samples. The recorded activity of papain in the samples containing the larvae was higher than that in the controls during the entire time of the experiment.

Opis:
Trophozoites of Balantidium coli were isolated from the pig's caecum and cultivated in vitro. Pigs were divided into two groups: one with the acute balantidiosis and the second - with the asymptomatic balantidiosis. In the first case the biotic potential of protozoans turned out to be higher (the most intensive divisions occurred 24 hours after the second passage). Protozoans isolated from pigs with the asymptomatic balantidiosis had lower biotic potential (the most intensive divisions occurred 24 hours after the third passage). This fact indicates the differentiation of the investigated populations of B. coli.

Opis:
The genus Scopulariopsis is a common soil saprotroph and has been isolated from air, organic waste and also from plant, animal and human tissues. Scopulariopsis has mainly been associated in humans with superficial mycoses, but it has also been described as the cause of subcutaneous and invasive infections. The most common aetiological agent of infections in humans is Scopulariopsis brevicaulis. This species has been reported to be resistant in vitro to broad-spectrum antifungal agents available today. The aim of the study was to establish in vitro antifungal susceptibility of 35 S. brevicaulis strains against amphotericin B (AMB), flucytosine (FC), caspofungin (CAS), terbinafine (TER), ciclopirox (CIC), voriconazole (VOR), clotrimazole (CTR), miconazole (MCZ), econazole (ECO), ketoconazole (KET), itraconazole (ITR), and fluconazole (FLU). Antifungal susceptibility tests were evaluated by an agar diffusion method (Neo-Sensitabs, Rosco, Denmark). AMB, FC, CAS, ITR and FLU showed no antifungal activity against S. brevicaulis. TER, CIC, CTR, KET, VOR, ECO, and MCZ revealed inhibitory activity for S. brevicaulis, but it varied for each of the drugs. The best antifungal effect was observed for TER and CIC. All isolates had large inhibition zones for TER and CIC. CTR was also inhibitory for all tested S. brevicaulis isolates, but the diameters of inhibition zones were smaller than for TER and CIC. Nearly 89% isolates showed inhibition zones for KET and the mean diameter of the inhibition zone was comparable to CTR. The least antifungal activity exhibited VOR, ECO and MCZ. Because of the multiresistance of S. brevicaulis, infections due to this species may not respond to particular antifungal treatment and other therapeutic approaches should be considered e.g., combined therapy and/or surgery.
