Samples from Vulcano hydrothermal system were incubated at hot temperatures with various electron donors and acceptors in order to isolate characterize strains belonging this environment. Eighteen isolated, which three seemed belong new species according their 16S rRNA sequence. These are under phenotypic genotypic characterization. Cultivation of representative taxa an environment helps unders...

A total of twenty-two strict anaerobic and Gram-positive Bifidobacteria, identified as B. adolescentis, B.pseudocatenulatum, or B. longum, were isolated from healthy adult Koreans. We here investigated the cellmorphology, antimicrobial resistance patterns to novel antibiotics and genotypic differentiation ofBifidobacteria assessing repetitive DNA element PCR (rep-PCR) fingerpr...

Lactobacillus sakei, a lactic acid bacterium naturally found in fresh meat and sea products, is considered to be one of the most important bacterial species involved in meat fermentation and bio-preservation. Several enzymes of Lb. sakei species contributing to microbial safeguarding and organoleptic properties of fermented-meat were studied. However, the specific autolytic mechanisms and assoc...

Cronobacter spp. (Enterobacter sakazakii) is an important pathogen contaminating powdered infant formula (PIF). To describe the genotypic diversity of Cronobacter isolated in China, we identified the isolates using fusA allele sequencing, and subtyped all of the isolates using pulsed-field gel electrophoresis (PFGE), multi-locus sequence typing (MLST), and multiple-locus variable-number tandem-...

AIM The purpose of this study was to characterize phenotypically and genotypically the serotypes of the E. coli O111 associated with diarrheal disease and assess the variation among serotypes in terms of specific virulence factors and HeLa cells adherence patterns. BACKGROUND Escherichia coli O111 serogroups are prevalent in endemic or sporadic cases of diarrhea, especially in developing area...

Cryptosporidium is an intestinal protozoan parasite that causes cryptosporidiosis. It also has been recognized as an important opportunistic pathogen affecting HIV-infected patients. It has been associated with chronic diarrhea, decreased quality of life, and shortened survival in HIV-infected patients. The prevalence of cryptosporidiosis in HIV-infected patients is 5-50%. However, in Thailand ...

Background: Motile Aeromonas species cause heavymortalities in carp farms during spring and summer in Iran. Objectives: The aim of this study was to detect phenotypicand genotypic characterization of motile Aeromonas species isolated fromdiseased carps in some northern and southern provinces of Iran. Methods: A number of 40 samples from 22 fish farms werecollected. The identified motile Aeromon...
