1. ENDOPHYTIC FUNGI COMMUNITY IN Eremanthus erythropappus TREE FROM ANTHROPOGENIC AND NATURAL AREAS OF MINAS GERAIS
ABSTRACT It is know that many plants live in symbiosis with microorganisms that can be found on their interior, the endophytes. Environment and tissue type are modulating factors of this community, in which most of these microorganisms produce important antimicrobial molecules and they may be powerful biocontrol agents in agriculture. Thus, the aim of this s

2. Prospecção e purificação de peptídeos com atividade antimicrobiana a partir de corais da costa brasileira
Concerns about information security becomes increasingly more primordial, leading organizations, including managers and individuals to gain minimum knowledge on information security and information leak prevention. Over time models were created texts and general references to basic precautions and instructions in the technological environment, with the evolu

3. Chemical characterization of bioactive compounds from the endophytic fungus Diaporthe helianthi isolated from Luehea divaricata
Endophytic microorganisms, defined as fungi or bacteria that colonize the interior of plants without causing any immediate negative effects or damages, have reciprocal relationships with host plants. In some cases their presence is beneficial to the host due to the synthesis of bioactive compounds, among which several alcohols, esters, ketones and others tha

4. Molecular battles between plant and pathogenic bacteria in the phyllosphere
The phyllosphere, i.e., the aerial parts of the plant, provides one of the most important niches for microbial colonization. This niche supports the survival and, often, proliferation of microbes such as fungi and bacteria with diverse lifestyles including epiphytes, saprophytes, and pathogens. Although most microbes may complete the life cycle on the leaf s

5. ATIVIDADE ANTIMICROBIANA DO Pg-AMP1 RECOMBINANTE, UM PEPTÍDEO RICO EM GLICINA, ISOLADO DE GOIABA (Psidium guajava L.)
The search for new antibiotics of broad spectrum of activity has increased in recent decades due to the increasing number of bacteria resistant to conventional antibiotics. The Pg-AMP1 recombinant peptide expressed in a heterologous system in Escherichia coli, strains showed antibacterial activity against Gram-positive and Gram-negative. From the sequence of

6. Antimicrobial activity of wax and hexane extracts from Citrus spp. peels
Antibacterial and antifungal properties of wax and hexane extracts of Citrus spp. peels were tested using bioautographic and microdilution techniques against three plant pathogenic fungi (Penicillium digitatum, Curvularia sp., and Colletotrichum sp.), two human pathogens (Trichophyton mentagrophytes and Microsporum canis), and two opportunistic bacteria (Esc

7. Identificação de um novo Antígeno de Paracoccidioides brasiliensis (Lumazina Sintase) através da Técnica de IVIAT
Paracoccidioides brasiliensis is a thermally dimorphic fungus causing paracoccidioidomycosis (PCM), a mycosis that affects 10 million individuals in Latin America. The infection is acquired by inhaling airborne propagules produced by the fungal mycelium which transforms into the pathogenic yeast form, when at the body temperature. P brasiliensis expresses in

8. Risk factors for human disease emergence.
A comprehensive literature review identifies 1415 species of infectious organism known to be pathogenic to humans, including 217 viruses and prions, 538 bacteria and rickettsia, 307 fungi, 66 protozoa and 287 helminths. Out of these, 868 (61%) are zoonotic, that is, they can be transmitted between humans and animals, and 175 pathogenic species are associated

9. Quantitative Evaluation of the Therapeutic Effects of Antibiotics Using Silkworms Infected with Human Pathogenic Microorganisms
The injection of bacteria (Staphylococcus aureus, Stenotrophomonas maltophilia) or true fungi (Candida albicans, Candida tropicalis) that are pathogenic to humans into the silkworm hemolymph leads to death of the larvae within 2 days. Antibiotics used for clinical purposes have therapeutic effects on silkworms infected with these pathogens. The 50% effective

11. Production of Penicillin by Fungi Growing on Food Products: Identification of a Complete Penicillin Gene Cluster in Penicillium griseofulvum and a Truncated Cluster in Penicillium verrucosum
Mycobiota growing on food is often beneficial for the ripening and development of the specific flavor characteristics of the product, but it can also be harmful due to the production of undesirable compounds such as mycotoxins or antibiotics. Some of the fungi most frequently isolated from fermented and cured meat products such as Penicillium chrysogenum and

12. Synergistic Enhancement of the Antifungal Activity of Wheat and Barley Thionins by Radish and Oilseed Rape 2S Albumins and by Barley Trypsin Inhibitors.
Although thionins and 2S albumins are generally considered as storage proteins, both classes of seed proteins are known to inhibit the growth of pathogenic fungi. We have now found that the wheat (Triticum aestivum L.) or barley (Hordeum vulgare L.) thionin concentration required for 50% inhibition of fungal growth is lowered 2- to 73-fold when combined with
