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 VQR, 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.</p>","PeriodicalId":23835,"journal":{"name":"Wiadomosci parazytologiczne","volume":"57 2","pages":"111-6"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29944395","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Numerous findings showed that microorganisms residing at different sites of human or animal body (natural microbiota), especially in the gastrointestinal tract, appear to contribute to nearly every element of the host's physiology. Recently, the microbiota is also supposed to be an underappreciated yet, but very important factor responsible for diverse vaccine efficacy observed in humans from developing vs. developed countries. In the article, selected aspects of the microbiota-host relation are presented: importance of the gut microbiota in the development of both the intestinal mucosal and systemic immune responses, bacteria of a predominant role for the immunity (e.g., SFB, Segmented Filamentous Bacteria), and several clinical observations on the varied immunogenicity of the same vaccines in different human populations. In the light of our current knowledge, manipulation of the microbiota by probiotics and/or prebiotics is becoming a realistic therapeutic and prophylactic strategy for many infectious, inflammatory and even neoplastic diseases within the gut but it may be also used for improving vaccine efficacy.</p>","PeriodicalId":23835,"journal":{"name":"Wiadomosci parazytologiczne","volume":"57 2","pages":"71-6"},"PeriodicalIF":0.0,"publicationDate":"2011-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"29943970","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The main objective was to investigate biodiversity of fungi and fungus-like organisms which take part in decomposition of organic matter commonly found in inland waters. To obtain a complete picture of species composition of fungi and fungus-like organisms in running waters we decided to explore representative sites of the Horodnianka River such as Olmonty, Hryniewicze and Horodniany with close localization of landfill. Fungal species were isolated using baiting technique. Baits of onion skin (Alium cepa), hemp-seeds (Cannabis sativa), impregnated cellophane and snake skin (Natrix natrix) were applied to isolate fungi from water of the Horodnianka River. The fungal community consists of 26 species, 10 species of fungi belonging to class Chytridiomycetes (3), anamorphic fungi (6), and Zygomycetes (1). 16 species belong to fungus-like organisms from class Oomycetes. Most of the recognized species have already been found in other running waters. From all the examined habitats the fungi belonging to 26 species of 18 genera Achlya, Alternaria, Aphanomyces, Aspergillus, Catenophlyctis, Dictyuchus, Fusarium, Karlingia, Lagenidium, Leptomitus, Olpidiopsis, Penicillium, Phlyctochytrium, Pythium, Saprolegnia, Scoliognia, Thraustotheca and Zoophagus were obtained. Certain fungal species like Aphanomyces laevis, Fusarium aqueductum, F. moniliforme, F. oxysporum, Leptomitus lacteus, Saprolegnia feax and S. parasitica were found at all the study sites. Among fungi potentially pathogenic and allergogenic for humans the genera Alternaria, Aspergillus, Fusarium, Lagenidium and Penicillium have already been described. However, the species Lagenidium giganteum and Achlya androgyna are new in the fungal biota of Poland. The greatest number of fungal species occurred in Olmonty (24), the smallest in Horodniany (13).

The present study shows results of research on species of ticks, their intensity and prevalence of infection in the domestic dogs in the district of Rymanów (Subcarpathian province, Poland). Local research was conducted from 25 August 2005 to 27 October 2006 on 82 randomly selected dogs in the veterinarian centre in Rymanów. Collected ticks were put into tubes with 70% ethyl alcohol. Collected and full up ticks were examined straight after being taken out of the preserving liquid. Stereoscopic microscope for species identification was used. The study revealed that domestic dogs in the Rymanów district are hosts for two species of ticks from the Ixodidae family: Ixodes (Ixodes) ricinus (Linnaeus, 1758) and Ixodes (Pholeoixodes) hexagonus Leach, 1815. Only one dog was infected with both tick species simultaneously. The dogs were attacked mainly by females. Ticks usually attached to such places as the neck, ear conches or groin. In general, the prevalence of ticks infestation on domestic dogs was 48.78%; I. ricinus prevalence was 47.56%, whereas I. hexagonus--2.43%.
