Candida Distribution in Onychomycosis and in vitro Susceptibility to Antifungal Agents

The aim of this study was to determine distribution of the Candida (C.) species in onychomycosis and analyses in vitro susceptibility to fluconazole and itraconazole. In recent years, cases of onychomycosis in Lithuania caused by Candida have increased significantly. In the period between 2009 and 2016, a total of 8149 clinical cases (outpatients and inpatients) were investigated at the Vilnius University Hospital Santaros Clinics (VUH SC). Candida yeasts were identified using VITEK 2 (BioMerieux, France) and IVD Maldi biotyper 2.3 (Bruker Daltonik GmbH, Germany), automated systems for identification of yeasts. The antifungal susceptibility to the Candida species were determined by disc diffusion. Candida spp. were the most frequently isolated pathogens in onychomycosis during the investigation period. The main species in onychomycosis were C. albicans (38.6%), followed by C. krusei (33.7%), C. tropicalis (11.1%), C. parapsilosis (7.9%), and other Candida (8.7%). The different antifungal susceptibility patterns among Candida species confirm the need to perform antifungal susceptibility in vitro testing of yeasts from patients with onychomycosi

Zoobentoso bendrijos Baltijos jūros priekrantės zonoje (Nidos–Juodkrantės akvatorija)

While studying regularities of the distribution of bioceonoses of the sea ground fauna, the abundance of animals and the amount of biomass, a direct connection can be noticed with the granulometric composition of bottom sediments and the depth. Coarser sediments of the bottom make optimum conditions for the development of zoobenthos. With the sediments getting finer and the depth decreasing, the biomass of some zoobenthic organisms also decreases (e. g., Macoma baltica), but the abundance of polychaetes (Pygospio elegans) notably increases. In the Nida-Juodkrantė water area where the bottom is vcovered with fine and intermediate sand, the dominant are the Pygospio elegans-Macoma baltica- Mesidotea entomon biocoenoses which are very important as a food resource for benthophagous fish, especially cod. This work offers an analysis of background data on macrozoobenthic communities at different depths of the Nida–Juodkrantė water area (the economic zone of the Republic of Lithuania)

New records and distribution patterns of the invasive snail Potamopyrgus antipodarum (Gray, 1843) in Lithuanian inland waters

This paper presents new records of P. antipodarum in inland waters of Lithuania, along with its distribution patterns in the country and within particular lakes. In the period 2014–2018, seven new records sites were found. The current distribution pattern of the snail suggests secondary dispersion vectors are accelerating the spread of the species between distant ecosystems. It was found that most initial records of the invader were in parts of the lakes with intensive water recreation activities. Additionally, analysis at the level of individual lakes indicated high population densities (on average (± SD) from 106.7 ± 45 to 1966.7 ± 1315.8 ind. m-2) in the parts of lakes with recreation activities, thereafter decreasing to zero with distance from these sites. Such results imply the possible role of overland movement of watercraft in the rapid dispersion of P. antipodarum over considerable distances

A contribution towards an understanding of the importance of some male genital structures of elachistidae for species identification

Straipsnyje nagrinėjama trijų plačiai paplitusių modelinių rūšių (Elachista albifrontella, E. pollinariella ir E. canapennella) patinų genitalinių struktūrų morfometrinių duomenų reikšmė identifikuojant rūšis. Pasitelkus 38 individų patinų genitalijų 24 matavimų dydžius bei faktorinę analizę nustatyta, kad rūšims apibūdinti tinkamesni yra absoliutūs matavimų dydžiai, o svarbiausios genitalinio komplekso dalys yra gnatoso ilgis ir tarpo tarp unkuso skiaučių plotis, ilgisThe importance of male genital structures for species identification was investigated using morphometric data of male genitalia of three widely distributed species: Elachista albifrontella, E. pollinariella, and E. canapennella. We used 24 measures of male genitalia of 38 specimens and carried out a factor analysis. Our results showed that absolute measures were more suitable for species identification. The length of gnathos and the width and length of the gap between uncus lobes were found to be the most important genital structures for species identificationGamtos tyrimų centrasVilniaus inžinerijos licėjusVytauto Didžiojo universitetasŠvietimo akademij
