Antibiotic-Based Conjugates Containing Antimicrobial HLopt2 Peptide: Design, Synthesis, Antimicrobial and Cytotoxic Activities
PublicationRecent studies have shown that modified human lactoferrin 20−31 fragment, named HLopt2, possesses antibacterial and antifungal activity. Thus, we decided to synthesize and evaluate the biological activity of a series of conjugates based on this peptide and one of the antimicrobials with proven antibacterial (ciprofloxacin, CIP, and levofloxacin, LVX) or antifungal (fluconazole, FLC) activity. The drugs were covalently connected...

The influence of oscillatory low pressure on bacteria number in groundwater supplied to distribution system
PublicationPrzedstawiono wyniki wstępnych badań laboratoryjnych nad wpływem stałego podwyższonego ciśnienia oraz częstych i gwałtownych jego zmian na liczbę bakterii w wodzie podziemnej. Określono zmiany liczby bakterii heterotroficznych (na agarze R2A) oraz całkowitej liczby bakterii (DAPI) w wodzie podziemnej (w temperaturze 20 st.C w okresie 96 h) poddawanej ciągłemu ciśnieniu 0,6 MPa i porównano z uzyskanymi w wodzie poddanej gwałtownym...

Effect of pH and high pressure at sub-zero temperature on the viability of some bacteria
PublicationCelem badań było określenie przeżywalności Escherichia coli i Staphylococcus aureus zawieszonych w soku jabłkowym (pH 3,8) po działaniu ciśnienia 193MPa w temperaturze -20°C. Stwierdzono, że bezpośrednio po działaniu ciśnienia przeżywalność badanych szczepów bakterii nie zmieniała się znacząco. Jednakże liczba komórek zmniejszała się z czasem przechowywania ciśnieniowanych prób. Żywe komórki mikroorganizmów nie były wykrywane w...

Whole-genome sequencing and antimicrobial potential of bacteria isolated from Polish honey
PublicationThe aim of this study was the whole-genome analysis and assessment of the antimicrobial potential of bacterial isolates from honey harvested in one geographical location—the north of Poland. In total, 132 strains were derived from three honey samples, and the antimicrobial activity of CFAM (cell-free after-culture medium) was used as a criterion for strain selection and detailed genomic investigation. Two of the tested isolates...

The first Polish interlaboratory comparision of the luminescent bacteria bioasssay with three standard toxicants
PublicationBadania biegłości laboratoriów z zastosowaniem odpowiednich materiałów referencyjnych powinny być regularnie wykonywane dla potwierdzenia jakości stosowanej procedury. W pracy zaprezentowano rezultaty pierwszych badań przeprowadzonych dla 9 polskich laboratoriów w zakresie oznaczania toksyczności z zastosowaniem bakterii Vibrio fischeri.Wyniki pokazują, że pierwsze polskie porównania międzylaboratoryjne biotestu opartego o bakterie...

Effect of high pressure and sub-zero temperature on some gram-negative bacteria.
PublicationCelem pracy było określenie przeżywalności wybranych gramujemnych bakterii na działanie wysokiego ciśnienia i ujemnej temperatury. Traktowanie komórek bakterii ciśnieniem 193 MPa w temperaturze -20C przez 24 godziny, powodowało całkowitą inaktywację bakterii E. coli, P. fluorescens i T. thermophilus. Po działaniu ciśnienia przez krótszy czas występowały różnice we wrażliwości między badanymi szczepami. Najmniej odporny na działanie...

PublicationBackground: Single-stranded DNA-binding proteins (SSBs) play essential roles in DNA replication, recombination and repair in Bacteria, Archaea and Eukarya. In recent years, there has been an increasing interest in SSBs, since they find numerous applications in diverse molecular biology and analytical methods. Results: We report the characterization of single-stranded DNA-binding proteins from the psychrophilic bacteria Desulfotalea...

Effect of lysozyme or nisin on survival of some bacteria treated with high pressure at subzero temperature
PublicationCelem pracy było określenie wrażliwości gramujemnych i gramdodatnich bakterii na działanie ciśnienia 193MPa w temp. -20°C w obecności lizozymu lub nizyny. Stwierdzono, że połączone działanie ciśnienia i badanych substancji przeciwdrobnoustrojowych na zawiesiny bakterii Escherichia coli i Staphylococcus aureus powodowało większy stopień inaktywacji komórek niż suma efektów wywieranych przez pojedyncze czynniki.

A New Double Digestion Ligation Mediated Suppression PCR Method for Simultaneous Bacteria DNA-Typing and Confirmation of Species: An Acinetobacter sp. Model
PublicationWe have designed a new ddLMS PCR (double digestion Ligation Mediated Suppression PCR) method based on restriction site polymorphism upstream from the specific target sequence for the simultaneous identification and differentiation of bacterial strains. The ddLMS PCR combines a simple PCR used for species or genus identification and the LM PCR strategy for strain differentiation. The bacterial identification is confirmed in the...
