FRUCTOPHILIC LACTIC ACID BACTERIA (FLAB) – A NEW GROUP OF HETEROFERMENTATIVE MICROORGANISMS FROM THE PLANT ENVIRONMENT

Recently, a unique kind of lactic acid bacteria (LAB) i.e. fructophilic lactic acid bacteria (FLAB), has been described. This specific group prefers D-fructose over D-glucose as a carbon source to growth. They can be found in fructose rich environments such as flowers, fruits and food products made of fermented fruits, for example tempoyak. In recent years, it has been revealed that insects which feed on food high in fructose are an abundant source of fructophilic bacteria. Bacterial

Probiotics promote and help to maintain beneficial microbiota composition of the gastrointestinal tract ecosystem and have a positive impact on the host’s health. Production of exopolysaccharides is an important feature of probiotic lactobacilli. It increases the chance of their survival in the gastrointestinal tract and promotes adhesion to the epithelium; therefore, exopolysaccharides are important for the process of colonization. Two lactic acid bacteria strains were used in this study

1. Introduction Apart from their basic metabolic activities, bacteria are also capable of synthesizing many biopolymers which differ in structure and chemical properties and thus in their functions in the cells. Considering their localization, biopolymers may be divided into intracellular (a small group with limited applications) and extracellular (a large group with wide applicability) ones. One of the classes of extracellular biopolymers includes exopolysaccharides (EPS). The EPS may be

replication. The aim of this work is to summarize the contemporary state of knowledge with regard to bacterial stringent response, which is significant due to its involvement in the reactions of microorganisms to the effects of stress factors, with particular emphasis on this mechanism in bacteria interacting with plants. The activation of the stringent response in bacteria gives them a chance to colonize new niches and, to an extent, guarantees their survival, even in extreme conditions. 2. RelA, SpoT

Comparison of PCR, Fluorescent in Situ Hybridization and Blood Cultures for Detection of Bacteremia in Children and Adolescents During Antibiotic Therapy

Abstract The gold standard in microbiological diagnostics of bacteremia is a blood culture in automated systems. This method may take several days and has low sensitivity. New screening methods that could quickly reveal the presence of bacteria would be extremely useful. The objective of this study was to estimate the effectiveness of these methods with respect to blood cultures in the context of antibiotic therapy. Blood samples from 92 children with sepsis were analyzed. Blood cultures were

A Novel Approach to Study the Effect of Ciprofloxacin on Biofilms of Corynebacterium spp. Using Confocal Laser Scanning Microscopy

× MIC paradoxically caused an enlargement of areas with live bacteria within the biofilm. Biofilm destruction required the application of ciprofloxacin at a concentration higher than 6 × MIC. This suggests that the use of relatively low doses of antimicrobial agents may increase the number of live bacteria within the biofilm, and further facilitate their detachment from the biofilm’s structure thus leading to the spread of bacteria into the bloodstream or to the neighboring tissues. The method of

ANTIBACTERIAL EFFECT OF NATURAL OILS – AN OPPORTUNITY TO SOLVE THE PROBLEM OF ANTIBIOTIC RESISTANCE ON THE EXAMPLE OF PSEUDOMONAS SPP.

1. Introduction The increase in consumption of antibiotics has provoked the formation of resistance mechanisms in bacteria as a result of chromosomal changes or the exchange of genetic material via plasmids and transposons. This problem involves many pathogenic bacteria, including Pseudomonas spp. For instance, P. aeruginosa (responsible for severe nosocomial infections) is a clinically significant pathogen with confirmed resistance to multiple classes of antibiotics, such as fluoroquinolones

Secondary Metabolites Produced by Heterorhabditis Symbionts and Their Application in Agriculture: What We Know and What to Do Next

Gram-negative Photorhabdus bacteria have a dual lifestyle: they are mutualists of Heterorhabditis nematodes and are pathogens of insects. Together, this nematode–bacterium partnership has been used to successfully control a wide range of agricultural insect pests. Photorhabdus produce a diverse array of small molecules that play key biological roles in regulating their dual roles. In particular, several secondary metabolites (SM) produced by this bacterium are known to play a critical role in

Colistin is only active against Gram-negative bacteria (GNB), such as the aerobic Enterobacterales ord. nov.

MICROBIOME OF THE WOMEN’S GENITAL SYSTEM

1. Introduction The human body is a unique living environment for many microorganisms characterized by a large diversity of species and genera. Bacteria, fungi, archaea and viruses colonizing the human body are called a microbiota [27]. They are found both on the skin surface and in the entire digestive system, from the oral cavity to the anus, in the upper respiratory tract and the urogenital system. However, most of them inhabit our digestive tract, including their greatest abundance in the

Inhibition of Drug Resistance of Staphylococcus aureus by Efflux Pump Inhibitor and Autolysis Inducer to Strengthen the Antibacterial Activity of β-lactam Drugs

Introduction Staphylococcus aureus infection and drug resistance problems have caused increasing public health problems. The increase in antimicrobial resistance coupled with intracellular infection makes this bacteria the third-largest threat to human health according to the WHO (Lowy 1998; Demon et al. 2012). MRSA is of particular concern because of its ability to spread extensively and rapidly, along with its multi-drug resistance to β-lactam and aminoglycoside antibiotics (Boucher et al

LISTERIOSIS. MODERN PERCEPTION OF EPIDEMIOLOGICAL THREAT

The presence of Listeria rods, especially Listeria monocytogenes, in the environment and food products, contributes each year to death of both humans and animals. The ability of bacteria to lead a saprophytic and parasitic existence as well as insensitivity to many physicochemical factors greatly facilitates the spread and guarantees access to a wide range of vulnerable organisms. Although the factors predisposing to infection result in a relatively low incidence of disease, infections are

THE APPLICATION OF GENOTYPING AND PHENOTYPING TECHNIQUES FOR EPIDEMIOLOGICAL ANALYSIS OF MICROORGANISMS

The research on similarity between bacteria in outbreak investigations enables the identification of bacterial strain responsible for infections, their source and modes of transmission. These investigations are also necessary for the analysis of spreading of bacteria, not only locally, e.g. in a hospital in a specific country, but also internationally and globally. Therefore, it is of great importance to have the most up to date knowledge regarding different methods used in bacterial typing

The paper presents a variety of microbiomes of the underground storage facilities and pipelines, showing that not only the sulfate-reducing bacteria are able to grow and develop in these extreme environments. Microorganisms producing CH4 may change the composition of the gas, and the produced H2S and CO2 are not only gas pollutants, but also generate corrosion of transmission networks. At the same time, the presence of bacteria and

growth of the root is too small to satisfy demand. So, P. polyphylla var. yunnanensis medicinal resources are close to depletion (Qi et al. 2013; Song et al. 2015). At present, the cultivation methods of P. polyphylla var. yunnanensis are mainly root block propagation and tissue culture, but tissue culture seedlings are easily infected by pathogenic bacteria, resulting in low yield (Duan et al. 2011). To make effective use of above-ground stems and leaves of P. polyphylla var. yunnanensis, and to
