AYSE N. CEYLAN/ OZDEN TUREL/ BILGE SUMBUL GULTEPE/ ELIF INAN/ AYSEL VEHAPOGLU TURKMEN/ MEHMET Z. DOYMAZ

Abstract Hand, foot, and mouth disease (HFMD) is caused by various serotypes of Enterovirus genus. Coxsackievirus A16 (CV-A16) and enterovirus A71 (EV-A71) were known to be the only responsible agents for these epidemics; however, this opinion was challenged after the detection that coxsackievirus A6 (CV-A6) was the responsible species for the outbreak in Finland in 2008. HFMD is frequently seen in Turkey, and no detailed study on its clinical and microbiological epidemiology has previously been(..)

Evaluation of The Pathogenic Potential of Insecticidal Serratia marcescens Strains to Humans

EDYTA KONECKA/ JOANNA MOKRACKA/ SYLWIA KRZYMIŃSKA/ ADAM KAZNOWSKI

Abstract We observed the death of insect caterpillars of Spodoptera exigua in the laboratory culture line and identified Serratia marcescens as the bacterial causative agent of the insect death. We confirmed that S. marcescens had insecticidal activity against S. exigua and caused high mortality of larvae. The LC50 values of S. marcescens CFU per 1 cm2 of insect diet surface were similar for all isolates. Our research reports novel strains with high pesticidal activity as candidates for future r(..)

Campylobacter fetus is Internalized by Bovine Endometrial Epithelial Cells

LIZETH GUADALUPE CAMPOS-MÚZQUIZ/ ESTELA TERESITA MÉNDEZ-OLVERA/ BEATRIZ ARELLANO-REYNOSO/ DANIEL MARTÍNEZ-GÓMEZ

Abstract Campylobacter fetus is an important venereal pathogen of cattle that causes infertility and abortions. It is transmitted during mating, and it travels from the vagina to the uterus; therefore, an important cell type that interacts with C. fetus are endometrial epithelial cells. Several virulence factors have been identified in the genome of C. fetus, such as adhesins, secretion systems, and antiphagocytic layers, but their expression is unknown. The ability of C. fetus to invade human e(..)

Influence of Environmental and Genetic Factors on Proteomic Profiling of Outer Membrane Vesicles from Campylobacter jejuni

RENATA GODLEWSKA/ JOANNA KLIM/ JANUSZ DĘBSKI/ AGNIESZKA WYSZYŃSKA/ ANNA ŁASICA

Abstract The proteomes of outer membrane vesicles (OMVs) secreted by C. jejuni 81–176 strain, which was exposed to oxygen or antibiotic stress (polymyxin B), were characterized. We also assessed the OMVs production and their content in two mutated strains – ∆dsbI and ∆htrA. OMVs production was significantly increased under the polymyxin B stress and remained unaltered in all other variants. Interestingly, the qualitative load of OMVs was constant regardless of the stress conditions or genetic ba(..)

JI-HOI MOON/ MI HEE NOH/ EUN-YOUNG JANG/ SEOK BIN YANG/ SANG WOOK KANG/ KYU HWAN KWACK/ JAE-IN RYU/ JIN-YONG LEE

Abstract Polyphosphate (polyP) is a food additive with antimicrobial activity. Here we evaluated the effects of sodium tripolyphosphate (polyP3, Na5P3O10) on four major oral bacterial species, in both single- and mixed-culture. PolyP3 inhibited three opportunistic pathogenic species: Fusobacterium nucleatum, Prevotella intermedia, and Porphyromonas gingivalis. On the contrary, a commensal bacterium Streptococcus gordonii was relatively less susceptible to polyP3 than the pathogens. When all bact(..)
