Studies of the interactions between humans and pathogenic microorganisms require adequate representative animal infection models. Further, the availability of invertebrate models overcomes the ethical and financial issues of studying vertebrate materials. Insects have an innate immune system that is conserved in mammals. The recent utilization of silkworms as an animal infection model led to th...

Studies have emphasized the importance of wild birds in the transmission of pathogenic microorganisms to other animals, whether wild or industrial birds, as well as in humans. Among these microorganisms, Salmonella spp. has shown relevant importance. Sousa et al. (2010a) captured 48 wild birds near poultry facilities in the North of São Paulo city, Brazil and detected three birds positive for S...

Essential oils of peppermint Mentha piperita L. (Lamiaceae), which are used in flavors, fragrances, and pharmaceuticals, were investigated for their antimicrobial properties against 21 human and plant pathogenic microorganisms. The bioactivity of the oils menthol and menthone was compared using the combination of in vitro techniques such as microdilution, agar diffusion, and bioautography. It w...

Many animal-pathogenic bacteria can use heme compounds as iron sources. Like these microorganisms, rhizobium strains interact with host organisms where heme compounds are available. Results presented in this paper indicate that the use of hemoglobin as an iron source is not restricted to animal-pathogenic microorganisms. We also demonstrate that heme, hemoglobin, and leghemoglobin can act as ir...

These compounds have the potential to inhibit or eliminate the presence of pathogenic microorganisms and antioxidant compounds with the ability to assist in the elimination of free radicals in the body [3,4]. Conversely, the efficacy of active substances of the essential oils on free radicals and pathogenic microorganisms can be influenced by environmental conditions of temperature, light and o...

This review reflects the current state of collection activities related to use pathogenic microorganisms. A modern regulatory framework regulating key aspects and activities, which is a critical step in microbial development, presented. number tasks facing collections solutions ensure biosafety sanitary-epidemiological well-being population Russian Federation have been defined. Directions for i...

Investigations on the pollution of groundwater with pathogenic microorganisms, e.g. tracer studies for groundwater transport, are constrained by their potential health risk. Thus, microspheres are often used in groundwater transport studies as non-hazardous surrogates for pathogenic microorganisms. Even though pathogenic microorganisms occur at low concentrations in groundwater, current detecti...

Introduction Saliva is commonly referred to as bloodstream of the oral cavity and has a major role in maintaining teeth enamel mineralization.(1) Saliva plays an important role in defense against pathogenic microorganisms due to the presence of defense proteins that react in specific (immunoglobulins) or non-specific (lysozyme, peroxidase, cystatins, lactoferrin, histatins) ways inhibiting the ...
