Abstract:
The work presents an analytical review of features of techniques for assessment of the pathogenetic potential of Helicobacter pylori bacterium, an etiological agent of a number of gastrointestinal diseases. The main emphasis is laid on modern molecular and genetic techniques that make it possible to assess not only the pathogenic potential of the bacterium, but also the characteristics of the stomach microbiota and the infected human host`s genotype.

Arcobacter butzleri is an emergent gram-negative enteropathogenic bacterium widespread in different environments and hosts. During the colonization of the gastrointestinal tract, bacteria face a variety of environmental conditions to successfully establish infection in a new host. One of these challenges is the fluctuation of oxygen concentrations encountered not only throughout the host gastrointestinal tract and defences but also in the food industry. Oxygen fluctuations can lead to modulations in the virulence of the bacterium and possibly increase its pathogenic potential. In this sense, e

Growth inhibition of these avian and human pathogens was observed after 4 h of incubation at 37°C in CAm broth, a medium developed according to the nutrients present in chicken food.

Abstract:
The Mycobacterium genus has important pathogenic species, such as M. leprae and M. tuberculosis, with high incidence in the human population. The number of bacterial strains resistant to antibiotics is steadily increasing, and in particular no new antibiotics have been developed for Mycobacterium. Mycobacteriophages have been shown to be viable alternatives, mainly to counteract antibiotic-resistant bacteria. A new mycobacteriophage (Myms-1) was isolated from sewage in Manaus, Amazonas state, Brazil, with lytic activity against M. smegmatis. Morphological analysis of the Mysm-1 phage shows tha

Abstract:
The genus Pantoea is a highly diverse group comprising free-living, and both pathogenic and non-pathogenic host-associating species. Pathogenic isolates have been found to infect insects, plants and humans, yet it is unclear whether these isolates have similar pathogenic potential to the free-living environmental populations. Using MLSA of six housekeeping genes, we evaluated the phylogenetic relationships among 115 environmental and clinical (human) isolates representing 11 Pantoea species.

Escherichia coli (E. coli) is a Gram-negative, commensal/pathogenic bacteria found in human intestines and the natural environment. Pathogenic E. coli is known as extra-intestinal pathogenic E. coli (ExPEC) or intestinal pathogenic E. coli (InPEC). InPEC E. coli strains are separated into six pathogenic groups, known as enteropathogenic (EPEC), enterotoxigenic (ETEC), enteroinvasive (EIEC), enteroaggregative (EAEC), enterohaemorrhagic (EHEC), and diffusely adherent (DAEC), that have various virulence factors that cause infection.

Alternatives to conventional antibiotics are needed for treating resistant bacterial infections. A deeper understanding of the cellular characteristics of resistant bacteria beyond w

Besides a role in infectious disease, this bacterium also seems to harbor immunomodulatory effects demonstrated by studies using C. acnes to enhance anti-tumor activity in various cancers or vaccination response.

We demonstrate that the corresponding antibacterial agents against P. aeruginosa PAO1 are volatile organic compounds (VOCs, namely VOC-3.9). Our findings show that VOC-3.9 leads to the abnormal cell division of P. aeruginosa PAO1 by disordering the expression of several essential division proteins associated with septal peptidoglycan sy

Campylobacter concisus is a bacterium that inhabits human oral cavities and is an emerging intestinal tract pathogen known to be a biofilm producer and one of the bacterial species found in dental plaque. In this study, biofilms of oral and intestinal C. concisus isolates were phenotypically characterized. The role of the luxS gene, which is linked to the regulation of biofilm formation in other pathogens, was assessed in relation to the pathogenic potential of this bacterium. Biofilm formation capacity was assessed using phenotypic assays. Oral strains were shown to be the highest producers.

Disposal of human biosolids is a source of concern for public health and the environment. Composting appears to be an interesting alternative to traditional disposal methods as it can decrease the load of human pathogenic microorganisms often present in biosolids and yield an end-product rich in nutrients for use as a soil supplement. Assessing the exact microbial content of biosolids, both for biosafety and operational reasons, has traditionally relied on the use of standard microbiological methods.

ABSTRACT Prebiotics such as fructooligosaccharides (FOS) are increasingly being used in some countries for improving human and animal health and as an alternative to antibiotic growth promoters in animals, with various degrees of success. It has been observed that FOS stimulate the proliferation of probiotic bacteria and, at the same time, decrease the population of bacteria associated with disease. This observation assumes that pathogenic bacteria do not metabolize FOS and, therefore, lose their competitive advantage over beneficial bacteria. Here we present evidence that some pathogenic Esch
